I have tried a number of solutions to get this working, but I could not find one that it working for me. I am a beginner at programming in C# with ASP.net, and I would appreciate any help that I can get.
Currently, my gridview allows me to sort, if I click on the column header, and this sorts it by ascending to descending order. However, when I click a link button i.e. one of the buttons in the 'flags' column of my programme, it does highlight that option (it is supposed to do it), but it doesn't keep the sort - I want it to keep the sort after this has been clicked. Would someone be able to help with this please?
Here is my aspx code (this is in asp:GridView):
<%--Flags column--%>
<asp:TemplateField HeaderText ="Flags" ItemStyle-Width="34px" SortExpression="sortFlag">
<ItemTemplate>
<div style="width:34px">
<asp:HiddenField ID="HidSortFlag" Value='<%#Eval("sortFlag") %>' runat="server" />
<asp:HiddenField ID="hidAmended" Value='<%#Eval("Amended") %>' runat="server" />
<asp:HiddenField ID="hidPayAnyway" Value='<%#Eval("PaymentOverrideFlag") %>' runat="server" />
<asp:HiddenField ID="hidQueries" Value='<%#Eval("QueryCount") %>' runat="server" />
<asp:HiddenField ID="hidSupplierRefCount" Value='<%#Eval("SupplierRefCount") %>' runat="server" />
<asp:HiddenField ID="hdnElementRef" Value='<%# Eval("SuggestedMatches") %>' runat="server" />
<asp:LinkButton ID="flagQueries" runat="server" Text="<span class='glyphicon glyphicon-comment' data-toggle='tooltip' data-placement='top' title='Comments and Queries'></span>" OnClick="flagQueries_Click" CommandArgument='<%# Eval("StatementLineId") +";"+Eval("SupplierRef") +";" + Eval("SuggestedMatches")%>' > </asp:LinkButton><br />
<asp:LinkButton ID="flagAmends" runat="server" Text="<span class='glyphicon glyphicon-flag' data-toggle='tooltip' data-placement='top' title='Related Booking Has Been Amended' ></span>" OnClick="flagAmends_Click" CommandArgument='<%# Eval("StatementLineId") %>'></asp:LinkButton><br />
<asp:LinkButton id="flagPayments" runat="server" Text="<span class='glyphicon glyphicon-ok' data-toggle='tooltip' data-placement='top' title='Pay Anyway'></span>" OnClick="flagPayments_Click" CommandArgument='<%# Eval("StatementLineId") + ";" +Eval("SuggestedMatches")%>'></asp:LinkButton> <br />
</div>
</ItemTemplate>
</asp:TemplateField>
Here is the code behind which does the sort:
protected void gridSummary_Sorting(object sender, GridViewSortEventArgs e)
{
//Check if the sort field is being used or a new sort
if (ViewState["summarySortField"] == null)
{
ViewState["summarySortField"] = e.SortExpression;
}
else if (ViewState["summarySortField"].ToString() != e.SortExpression)
{
ViewState["summaryDirectionState"] = null;
ViewState["summarySortField"] = e.SortExpression;
}
summaryDirection = summaryDirection == SortDirection.Ascending ? SortDirection.Descending : SortDirection.Ascending;
string sortingDirection = summaryDirection == SortDirection.Ascending ? "Desc" : "Asc";
DataView summaryView = LoadStatement();
summaryView.Sort = string.Format("{0} {1}", e.SortExpression, sortingDirection);
//Session["SortedView"] = summaryView;
gridSummary.DataSource = summaryView;
gridSummary.DataBind();
//ColourFlags();
}
public SortDirection summaryDirection
{
get
{
if (ViewState["summaryDirectionState"] == null)
{
ViewState["summaryDirectionState"] = SortDirection.Ascending;
}
return (SortDirection)ViewState["summaryDirectionState"];
}
set
{
ViewState["summaryDirectionState"] = value;
}
}
protected void gridDetail_Sorting(object sender, GridViewSortEventArgs e)
{
//Check if the sort field is being used or a new sort
if (ViewState["detailSortField"] == null)
{
ViewState["detailSortField"] = e.SortExpression;
}
else if (ViewState["detailSortField"].ToString() != e.SortExpression)
{
ViewState["detailDirectionState"] = null;
ViewState["detailSortField"] = e.SortExpression;
}
detailDirection = detailDirection == SortDirection.Ascending ? SortDirection.Descending : SortDirection.Ascending;
string sortingDirection = detailDirection == SortDirection.Ascending ? "Desc" : "Asc";
//string gets toggle error field in order to add the colour red to certain columns
DataView detailView = LoadDetails(Session["arg"].ToString());
string[] args = Session["arg"].ToString().Split(';');
string status = args[0];
detailView.Sort = string.Format("{0} {1}", e.SortExpression, sortingDirection);
//Session["SortedView"] = summaryView;
gridDetail.DataSource = detailView;
gridDetail.DataBind();
ColourFlags();
ToggleErrorFields(string.IsNullOrEmpty(status));
}
public SortDirection detailDirection
{
get
{
if (ViewState["detailDirectionState"] == null)
{
ViewState["detailDirectionState"] = SortDirection.Ascending;
}
return (SortDirection)ViewState["detailDirectionState"];
}
set
{
ViewState["detailDirectionState"] = value;
}
}
Here is the click event for one of the flags:
protected void flagAmends_Click(object sender, EventArgs e)
{
LinkButton faBtn = sender as LinkButton;
int lineId = int.Parse(faBtn.CommandArgument);
using (SpamEntities spam = new SpamEntities())
{
SPM_Statement_Lines line = spam.SPM_Statement_Lines.Where(x => x.StatementLineID == lineId).FirstOrDefault();
line.Amended = !line.Amended;
spam.SaveChanges();
}
//reloads gridview
LoadDetails(hidStatus.Value + ";" + hidCategory.Value + ";" + lineId);
}
After the button clicks the button changes colour, and performs the necessary action, however it does not keep its sort - I have been trying to fix this but I have not been successful. I would appreciate any clear step by step solutions.

I need to set 3 different groups of radio button in a repeater. Using groupname property for it wasn't enough. So, after researching, I use a bit of JS and it works. My problem is when I want to implement more than one group of radiobuttons. Can anyone help me?
My best approach is:
CSHTML
<asp:Repeater runat="server" ID="repeaterImages" OnItemDataBound="repeaterImages_ItemDataBound">
<ItemTemplate>
<span>
<asp:RadioButton runat="server" ID="rbLogoSeleccionado" Text='Logo 0' GroupName="nombreLogo" /><br />
<asp:RadioButton runat="server" ID="rbLogoSeleccionadoApp" Text='Logo 1' GroupName="nombreLogoApp" /><br />
<asp:RadioButton runat="server" ID="rbLogoSeleccionadoAppBlanco" Text='Logo 2' GroupName="nombreLogoAppBlanco" />
</span>
</ItemTemplate>
</asp:Repeater>
JS
<script>
function SetUniqueRadioButton(nameregex, current) {
for (i = 0; i < document.forms[0].elements.length; i++) {
elm = document.forms[0].elements[i]
if (elm.type == 'radio') {
elm.checked = false;
}
}
current.checked = true;
}
</script>
CS
protected void repeaterImages_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
try
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
RadioButton rbLogoSeleccionado = (RadioButton)e.Item.FindControl("rbLogoSeleccionado");
RadioButton rbLogoSeleccionadoApp = (RadioButton)e.Item.FindControl("rbLogoSeleccionadoApp");
RadioButton rbLogoSeleccionadoAppBlanco = (RadioButton)e.Item.FindControl("rbLogoSeleccionadoAppBlanco");
string script = "SetUniqueRadioButton('repeaterImages.*nombreLogo',this)";
string scriptApp = "SetUniqueRadioButton('repeaterImages.*nombreLogoApp',this)";
string scriptAppBlanco = "SetUniqueRadioButton('repeaterImages.*nombreLogoAppBlanco',this)";
rbLogoSeleccionado.Attributes.Add("onclick", script);
rbLogoSeleccionadoApp.Attributes.Add("onclick", scriptApp);
rbLogoSeleccionadoAppBlanco.Attributes.Add("onclick", scriptAppBlanco);
}
}
catch (Exception ex)
{
PIPEvo.Log.Log.RegistrarError(ex);
throw;

With this code just getting 3 rows of radiobutton, sharing groupname behavior for all of them... (I want groupname behavior per row...)
Piece of cake. Prove how newie I am in JS. I am posting the solution because is a recurrent issue in asp programming and this bug is known. Beside I cant find the solution for some radio button.
JS.
<script>
function SetUniqueRadioButton(text, current) {
for (i = 0; i < document.forms[0].elements.length; i++) {

I am trying to store files from a Gridview upload into a Folder using Asp.net.
This is my markup code to generate Upload column and The button and File Upload control.
<asp:TemplateField HeaderText="Upload">
<ItemTemplate>
<asp:FileUpload ID="FileUpload1" runat="server" EnableViewState="true" AllowMultiple="true" />
<asp:Button ID="btnUpload" runat="server" CommandName="Upload" Text="OK" style=" color: #ff0000" OnClick="btnUpload_Click"/>
</ItemTemplate>
</asp:TemplateField>
I have my codebehind to handle btnUpload_Click as below:
protected void btnUpload_Click(object sender, GridViewCommandEventArgs e)
{
Response.Write("File has been passed");
Button bts = e.CommandSource as Button;
Response.Write(bts.Parent.Parent.GetType().ToString());
if (e.CommandName.ToLower() != "upload")
{
return;
}
FileUpload fu = bts.FindControl("FileUpload4") as FileUpload;//here
if (fu.HasFile)
{
bool upload = true;
string fleUpload = Path.GetExtension(fu.FileName.ToString());
if (fleUpload.Trim().ToLower() == ".xls" | fleUpload.Trim().ToLower() == ".xlsx")
{
fu.SaveAs(Server.MapPath("~/UpLoadPath/" + fu.FileName.ToString()));
string uploadedFile = (Server.MapPath("~/UpLoadPath/" + fu.FileName.ToString()));
//Someting to do?...
}
else
{
upload = false;
// Something to do?...
}
if (upload)
{
// somthing to do?...
}
}
else
{
//Something to do?...
}
}
I am getting this error:
CS0123: No overload for 'btnUpload_Click' matches delegate
'System.EventHandl
Can somebody please help me?
You're binding both Command and Click event with your button. Your button code should be like this-
<asp:TemplateField HeaderText="Upload">
<ItemTemplate>
<asp:FileUpload ID="FileUpload1" runat="server" EnableViewState="true" AllowMultiple="true" />
<asp:Button ID="btnUpload" runat="server" CommandName="Upload" Text="OK" style=" color: #ff0000"/>
</ItemTemplate>
</asp:TemplateField>
and from code behind capture the command not the event. like-
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
Response.Write("File has been passed");
Button bts = e.CommandSource as Button;
Response.Write(bts.Parent.Parent.GetType().ToString());
if (e.CommandName.ToLower() != "upload")
{
return;
}
FileUpload fu = bts.FindControl("FileUpload1") as FileUpload;//here
if (fu.HasFile)
{
bool upload = true;
string fileName = Path.GetFileName(fu.PostedFile.FileName);
string fleUpload = Path.GetExtension(fu.PostedFile.FileName);
if (fleUpload.Trim().ToLower() == ".xls" || fleUpload.Trim().ToLower() == ".xlsx")
{
fu.SaveAs(Server.MapPath("~/UpLoadPath/" + fileName));
string uploadedFile = (Server.MapPath("~/UpLoadPath/" + fileName ));
//Someting to do?...
}
else
{
upload = false;
// Something to do?...
}
if (upload)
{
// somthing to do?...
}
}
else
{
//Something to do?...
}
}
above I'm assuming your gridview ID is GridView1. And another one your File Uploader control's ID was mismatched with your code behind. This should work.
Hello Friends my Pagination works fine, but when sort any column, it gets sorted on first page but on next pages sorting gets lost.
Please any one can help me to figure this out.
My Markup Code for .aspx
<asp:TemplateField HeaderText="Actions" ItemStyle-Width="20%">
<ItemTemplate>
<span class="glyphicon glyphicon-eye-open"></span>View
</span>Edit
</span>Delete
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Substance_ID" HeaderText="Substance ID" SortExpression="Substance_ID" />
<asp:TemplateField HeaderText="CAS Number" ItemStyle-Width="10%" SortExpression="CAS_Number">
<ItemTemplate>
<%# Eval("CAS_Number").ToString().Trim()%>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="EC Number" ItemStyle-Width="10%" SortExpression="EC_Number">
<ItemTemplate>
<%# Eval("EC_Number").ToString().Trim()%>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Substance Name" SortExpression="Substance_Name">
<ItemTemplate>
<%#Eval("Substance_Name").ToString().Trim()%>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Primary SG ID" ItemStyle-Width="10%" SortExpression="Primary_SG_ID">
<ItemTemplate>
<%#Eval("Primary_SG_ID")%>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Status" ItemStyle-Width="5%" SortExpression="Status">
<ItemTemplate>
<%#Eval("Status")%>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<PagerStyle CssClass="my_pagination" />
<PagerSettings Mode="NumericFirstLast" FirstPageText="First" LastPageText="Last" PageButtonCount="10" />
<EmptyDataTemplate>No Data</EmptyDataTemplate>
</asp:GridView>
<asp:Label runat="server" ID="lblCount"></asp:Label>
And My Code Behind:
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
BindGridViewData();
}
}
private void BindGridViewData()
{
List<Substance_Display> Substance_List = new List<Substance_Display>();
Substance_List = Substance_MasterAccessLayer.GetAllSubstances("Substance_ID");
Substance_Master.DataSource = Substance_List;
Substance_Master.DataBind();
lblCount.Text = "Total " + Substance_List.Count().ToString() + " Records found.";
}
protected void Substance_Master_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
Substance_Master.PageIndex = e.NewPageIndex;
Substance_Master.DataBind();
}
private void SortGridView(GridView Substance_Master, GridViewSortEventArgs e, out SortDirection sortDirection, out string sortField)
{
sortField = e.SortExpression;
sortDirection = e.SortDirection;
if (Substance_Master.Attributes["CurrentSortField"] != null & Substance_Master.Attributes["CurrentSortDirection"] != null)
{
if (sortField == Substance_Master.Attributes["CurrentSortField"])
{
if (Substance_Master.Attributes["CurrentSortDirection"] == "ASC")
{
sortDirection = SortDirection.Descending;
}
else
{
sortDirection = SortDirection.Ascending;
}
}
Substance_Master.Attributes["CurrentSortField"] = sortField;
Substance_Master.Attributes["CurrentSortDirection"] = (sortDirection == SortDirection.Ascending ? "ASC" : "DESC");
}
}
protected void Substance_Master_Sorting(object sender, GridViewSortEventArgs e)
{
SortDirection sortDirection = SortDirection.Ascending;
string sortField = string.Empty;
SortGridView(Substance_Master, e, out sortDirection, out sortField);
string strSortDirection = sortDirection == SortDirection.Ascending ? "ASC" : "DESC";
Substance_Master.DataSource = Substance_MasterAccessLayer.GetAllSubstances(e.SortExpression + " " + strSortDirection);
Substance_Master.DataBind();
}
EDIT: I would suggest the following to fix the issue:
Change your Page_Load method to this:
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
Substance_Master.Attributes["CurrentSortField"] = "Substance_ID";
Substance_Master.Attributes["CurrentSortDirection"] = "ASC";
BindGridViewData();
}
}
And change the Substance_Master_PageIndexChanging method to this:
protected void Substance_Master_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
Substance_Master.PageIndex = e.NewPageIndex;
var sortField = Substance_Master.Attributes["CurrentSortField"];
var sortDirection = Substance_Master.Attributes["CurrentSortDirection"];
if (sortField != null && sortDirection != null)
{
Substance_Master.DataSource = Substance_MasterAccessLayer.GetAllSubstances(sortField + "" + sortDirection);
}
Substance_Master.DataBind();
}
Explanation: You need to set the datasource of GridView before databind in PageIndexChanging event method. And you may need to sort the datasource depending on the current sort conditions.
How to enable the sorting for dynamically setting the lbl field text in a GridView. Below is the code for the GridView and .cs code where i am setting the value for the dynamic label field. The question is, I am not able to apply the sorting expression for this particular asp:template similar to other templates.
<asp:GridView ID="gvAlertsStatus" runat="server" AllowSorting="true"
OnSorting="gvAlertsStatus_Sorting" AutoGenerateColumns="false"
OnRowDataBound="gvAlertsStatus_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="Owner" SortExpression="UsrName"
ItemStyle-Width="120px">
<ItemTemplate><%#Eval("UsrName") %></ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Last Result" SortExpression="lblLastResult"
ItemStyle-Width="40px" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Label runat="server" ID="lblLastResult" Font-Bold="true">
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Active" SortExpression="Active"
ItemStyle-Width="60px" >
<ItemTemplate>
<asp:Label runat="server" ID="lblActive"
Text='<%#Eval("Active") %>' >
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
.aspx.cs code
public void gvAlertsStatus_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex >= 0)
{
Label lblLastResult = (Label)e.Row.FindControl("lblLastResult");
// Get the dates
DateTime dtSuccess = (eScan.Lib.Shared.Utils.IsDate(lblSuccess.Text)) ?
DateTime.Parse(lblSuccess.Text) : DateTime.MinValue;
DateTime dtFailure = (eScan.Lib.Shared.Utils.IsDate(lblFailure.Text)) ?
DateTime.Parse(lblFailure.Text) : DateTime.MinValue;
DateTime dtDelay = (eScan.Lib.Shared.Utils.IsDate(lblDelay.Text)) ?
DateTime.Parse(lblDelay.Text) : DateTime.MinValue;
DateTime dtLastRun = (dtSuccess > dtFailure) ? dtSuccess : dtFailure;
// Set up the Last Result label
lblLastResult.Text = (dtSuccess > dtFailure) ? "Success" : "Fail";
}
}
protected void gvAlertsStatus_Sorting(object sender, GridViewSortEventArgs e)
{
// Set up the sort direction
SortDirection sd = SortDirection.Ascending;
// If the same column is clicked, then alternate sort direction
if (e.SortExpression.Equals(ViewState["SortExp"]))
{
sd = ((SortDirection)ViewState["SortDir"] == SortDirection.Descending) ?
SortDirection.Ascending : SortDirection.Descending;
}
// Save the states
ViewState["SortExp"] = e.SortExpression;
ViewState["SortDir"] = sd;
// Sort the view and rebind that
DataView dv = (DataView)gvAlertsStatus.DataSource;
dv.Sort = e.SortExpression + " " +
((sd == SortDirection.Descending) ? "DESC" : "ASC");
gvAlertsStatus.DataSource = dv;
gvAlertsStatus.DataBind();
}
Try this code.........
protected void RadgvData_SortCommand(object sender, GridSortCommandEventArgs e)
{
GridTableView tableView = e.Item.OwnerTableView;
e.Canceled = true;
GridSortExpression expression = new GridSortExpression();
expression.FieldName = e.SortExpression;
if (tableView.SortExpressions.Count == 0 || tableView.SortExpressions[0].FieldName != e.SortExpression)
{
expression.SortOrder = GridSortOrder.Descending;
}
else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Descending)
{
expression.SortOrder = GridSortOrder.Ascending;
}
else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Ascending)
{
expression.SortOrder = GridSortOrder.Descending;
}
tableView.SortExpressions.AddSortExpression(expression);
RadgvData.Rebind();
}
How to apply basic sorting in the gridview? Below is the gridview code.
<asp:TemplateField SortExpression="Sample1">
<HeaderTemplate SortExpression="Sample1">
<asp:Literal ID="litSample1" runat="server" Text="<%$ Resources:Resource, gvColSample1 %>"></asp:Literal>
<asp:DropDownList ID="ddlSample1" runat="server" OnSelectedIndexChanged="SelectionChanged" AutoPostBack="true" CssClass="dropdownS" AppendDataBoundItems="true">
<asp:ListItem Text=" " Value="-1"></asp:ListItem>
<asp:ListItem Text="ALL" Value="ALL"></asp:ListItem>
</asp:DropDownList>
</HeaderTemplate>
<ItemTemplate>
<%# Eval("RowSample1") %>
</ItemTemplate>
</asp:TemplateField>
As you can see the header template contains a literal. So how to apply sorting? will the addition of literal make a difference in applying sorting?
Use sort expression with template field and use the following code for sorting. ITs working perfectly fine for me.
protected void gvTool_Sorting(object sender, GridViewSortEventArgs e)
{
if (ViewState["sortMode"] == null)
{
ViewState["sortMode"] = SORT_DESC;
}
if (ViewState["sortMode"] != null)
{
if (Convert.ToString(ViewState["sortMode"]).Trim().Equals(SORT_ASC))
{
ViewState["sortMode"] = SORT_DESC;
}
else
{
ViewState["sortMode"] = SORT_ASC;
}
}
string sortexpr = e.SortExpression;
ViewState["sortexpr"] = e.SortExpression;
sort();
}
protected void sort()
{
if (ViewState["sortexpr"] != null)
{
DataView dvTool = default(DataView);
DataTable dtTool = new DataTable();
dtTool = (DataTable)ViewState["dtTool"];
if ((dtTool != null))
{
if (dtTool.Rows.Count > 0)
{
dvTool = dtTool.DefaultView;
dvTool.Sort = ViewState["sortexpr"].ToString().Trim() + " " + ViewState["sortMode"];
gvTool.DataSource = dvTool;
gvTool.DataBind();
}
}
}
}
