How to have a colspan with gridview - c#

I'm trying to make a grid view with asp.net. I want that columns' headers have a colspan like that :
But for the moment I have :
My code is :
<asp:GridView ID="GV" runat="server" AutoGenerateColumns="false" OnPreRender="gridView_PreRender">
<Columns>
<asp:BoundField HeaderText="" />
<asp:BoundField HeaderText="Num OF" DataField="cod_wo" />
<asp:BoundField HeaderText="Num Seq" DataField="dat_sequence" />
<asp:BoundField HeaderText="Article" DataField="article"/>
<asp:BoundField HeaderText="Qté OF Prévue" DataField="wo_qty" />
<asp:BoundField HeaderText="Qté OF Revue" DataField="qty_revue" />
<asp:BoundField HeaderText="Composant" DataField="composant" />
<asp:BoundField HeaderText="Restant à assigner" DataField="restant_a_assigner" />
<asp:BoundField HeaderText="Assignation HU" />
<asp:BoundField HeaderText="Qté totale" DataField="qte_totale_assignee" />
<asp:BoundField HeaderText="Num HU" DataField="num_hu" />
<asp:BoundField HeaderText="Qté" DataField="qte_assignee" />
</Columns>
</asp:GridView>
and in code behind C# i have :
public static void MergeColumns(GridView gridView)
{
gridView.HeaderRow.Cells[0].RowSpan = 2;
gridView.HeaderRow.Cells[1].RowSpan = 2;
gridView.HeaderRow.Cells[2].RowSpan = 2;
gridView.HeaderRow.Cells[3].RowSpan = 2;
gridView.HeaderRow.Cells[4].RowSpan = 2;
gridView.HeaderRow.Cells[5].RowSpan = 2;
gridView.HeaderRow.Cells[6].RowSpan = 2;
gridView.HeaderRow.Cells[7].RowSpan = 2;
gridView.HeaderRow.Cells[8].ColumnSpan = 3;
}
Do you have an idea ? thanks

You can do by using RowCreated event of grid view.For better understanding follow This Link
Hope it solves your problem.

Grid view footer not showing

I am building a gridview from an arraylist and want to include a footer to the bottom.
This is my c# code
gvOrder.DataSource = orderItemList;
gvOrder.DataBind();
gvOrder.ShowFooter = true;
gvOrder.Columns[0].FooterText = "Totals:";
gvOrder.Columns[2].FooterText = Convert.ToString(quantity);
gvOrder.Columns[4].FooterText = Convert.ToString(priceTotal);
Here is my asp code
<asp:GridView ID="gvOrder" runat="server" AutoGenerateColumns="False" ShowFooter="True">
<Columns>
<asp:BoundField DataField="ItemTitle" HeaderText="Title" />
<asp:BoundField DataField="ItemFormat" HeaderText="Format" />
<asp:BoundField DataField="ItemQuantity" HeaderText="Quantity" />
<asp:BoundField DataField="ItemPrice" HeaderText="Price" />
<asp:BoundField DataField="ItemTotal" HeaderText="Total" />
</Columns>
</asp:GridView>
The order of things matter. You have to set the footer values before DataBind() is called.
gvOrder.Columns[0].FooterText = "Totals:";
gvOrder.Columns[2].FooterText = Convert.ToString(quantity);
gvOrder.Columns[4].FooterText = Convert.ToString(priceTotal);
gvOrder.DataSource = orderItemList;
gvOrder.DataBind();
gvOrder.ShowFooter = true;
But you can set the values of the Footer Row after DataBind if you specify the footerrow cells instead of the Colums.
gvOrder.FooterRow.Cells[1].Text = "After DataBind";

How can I find a BoundField inside a GridView by DataField?

I want to change the CSS class behind the tenth BoundField inside my GridView, but I'd like to find it by DataField (i.e., use a string as index).
protected void gdDeliveryDates_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string DeliveryDue = DataBinder.Eval(e.Row.DataItem, "DeliveryDue").ToString();
((LinkButton) e.Row.FindControl("PostDelivery")).Enabled = !String.IsNullOrEmpty(DeliveryDue);
//e.Row.Cells[9].CssClass= "badge";
}
}
In the code above I have commented out the only solution I've found so far, which to me is unacceptable because a column number (i.e., column 9 as specified above) is very volatile. I would prefer to find the column by DataField (a string, in this case, "MailCount" as you'll see in the grid declaration further ahead). Below is what my grid looks like:
<asp:GridView ID="gdDeliveryDates" runat="server" AllowPaging="False" AllowSorting="True" DataSourceID="odsDeliveryDates" AutoGenerateColumns="False" CssClass="table table-striped table-bordered table-hover" OnRowCommand="gdDeliveryDates_RowCommand" OnSelectedIndexChanged="gdDeliveryDates_SelectedIndexChanged" DataKeyNames="PackageOfferedID, PackageID, PostageID, PackageNumber, PackageTitle, PostageName, Section, PostageStart, PostageEnd, DeliveryDue, LName, MailCount, Location" OnRowDataBound="gdDeliveryDates_RowDataBound" >
<Columns>
<asp:BoundField DataField="PackageID" HeaderText="PackageID" Visible="False" ReadOnly="True" SortExpression="PackageID" />
<asp:BoundField DataField="PackageOfferedID" HeaderText="PackageOfferedID" Visible="False" ReadOnly="True" SortExpression="PackageOfferedID" />
<asp:BoundField DataField="PostageID" HeaderText="PostageID" Visible="False" ReadOnly="True" SortExpression="PostageID" />
<asp:BoundField DataField="PackageNumber" HeaderText="Package" Visible="True" ReadOnly="True" SortExpression="PackageNumber" HeaderStyle-CssClass="visible-xs visible-sm visible-md visible-lg" ItemStyle-CssClass="visible-xs visible-sm visible-md visible-lg" />
<asp:BoundField DataField="PostageName" HeaderText="Postage" ReadOnly="True" SortExpression="PostageName" HeaderStyle-CssClass="visible-sm visible-md visible-lg" ItemStyle-CssClass="visible-sm visible-md visible-lg"/>
<asp:BoundField DataField="Section" HeaderText="Section" ReadOnly="True" SortExpression="Section" HeaderStyle-CssClass="visible-xs visible-sm visible-md visible-lg" ItemStyle-CssClass="visible-xs visible-sm visible-md visible-lg" />
<asp:BoundField DataField="PostageStartDate" HeaderText="Start Date" ReadOnly="True" SortExpression="PostageStartDate" DataFormatString="{0:MM/dd/yyyy}" HeaderStyle-CssClass="visible-md visible-lg" ItemStyle-CssClass="visible-md visible-lg" />
<asp:BoundField DataField="PostageEndDate" HeaderText="End Date" ReadOnly="True" SortExpression="PostageEndDate" DataFormatString="{0:MM/dd/yyyy}" HeaderStyle-CssClass="visible-md visible-lg" ItemStyle-CssClass="visible-md visible-lg" />
<asp:BoundField DataField="DeliveryDueDate" HeaderText="Delivery Due" ReadOnly="True" SortExpression="DeliveryDueDate" DataFormatString="{0:MM/dd/yyyy}" HeaderStyle-CssClass="visible-xs visible-sm visible-md visible-lg" ItemStyle-CssClass="visible-xs visible-sm visible-md visible-lg" />
<asp:BoundField DataField="MailCount" HeaderText="#" Visible="True" ReadOnly="True" SortExpression="MailCount" HeaderStyle-CssClass="visible-lg" ItemStyle-CssClass="visible-lg" />
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="PostDelivery" runat="server" CausesValidation="false" CommandName="Add"
Text="Post Delivery" CommandArgument='<%# DataBinder.Eval(Container, "RowIndex") %>'
CssClass="buttonLayout" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="LName" HeaderText="LName" Visible="False" ReadOnly="True" SortExpression="LName" />
<asp:BoundField DataField="Location" HeaderText="Location" Visible="False" ReadOnly="True" SortExpression="Location" />
</Columns>
</asp:GridView>
This is not possible but you can try this method:
public int FindIndexByDataField(this GridView gv, string datafieldname)
{
int index = -1, cnum = 0;
foreach (DataControlField col in gv.Columns)
{
if (col is BoundField)
{
BoundField coll = (BoundField)gv.Columns[cnum];
if (coll.DataField == datafieldname)
{
index = cnum;
break;
}
}
cnum++;
}
return index;
}
And call above method like this:
e.Row.Cells[FindIndexByDataField("MailCount")].CssClass= "badge";

Not able to access hyperlink column inside gridview from code behind

I want to access the HyperLinkField column of the GridView from code behind but I am unable to do so.
I have the column in my dataset but I am still not able to use it.
My HyperLinkField column is named Status.
Here is what I tried:
UltraWebGrid1.DataSource = ObjPriDsGrid;
UltraWebGrid1.DataBind();
string StrPriStatus = "";
for (int IntPriI = 0; IntPriI < UltraWebGrid1.Rows.Count; IntPriI++)
{
if (UltraWebGrid1.Rows[IntPriI].Cells[6].Text.Trim() != null)
{
StrPriStatus = UltraWebGrid1.Rows[IntPriI].Cells[6].Text.Trim();
}
else
{
}
if (StrPriStatus == "5")
{
UltraWebGrid1.Rows[IntPriI].Cells[8].Text = ""; // Not getting status column here
}
}
Here is my GridView:
<asp:GridView ID="UltraWebGrid1" ShowHeader="true" runat="server" AutoGenerateColumns="false"
DataKeyNames="mkey" OnRowDataBound="Grid_RowDataBound" Width="98%" Height="30%"
PageSize="10" AllowPaging="true" OnPageIndexChanging="Grid1_PageIndexChanging"

DataNavigateUrlFormatString="~/Administration/Dispatch/Inward/FrmInwardNextAction.aspx?Inward_mkey={0}&Status={0}&IWNO={0}"
HeaderText="Status" DataTextField="Status" Target="_blank" />
<asp:HyperLinkField ItemStyle-Width="5%" DataNavigateUrlFields="Mkey, Status, Doc_No"
HeaderText="View" DataTextField="View" Target="_blank" DataNavigateUrlFormatString="~/Administration/Dispatch/Inward/InwardDocDetails.aspx?Key={0}&Status={0}&IWNO={0}" />
</Columns>
</asp:GridView>
Columns like HyperLinkField and CheckBoxField behave a little differently than BoundField. They don't just simply contain text like BoundField. You have to get the control within the cell. You can get the child controls of the cell using the Controls collection. We know that specifically for a HyperLinkField, the HyperLink will be the first control in the collection.
HyperLink hyp = (HyperLink)UltraWebGrid1.Rows[IntPriI].Cells[12].Controls[0];
Can you try it like this
if (StrPriStatus == "5")
{
HyperLink HyperLinkObj = (HyperLink)UltraWebGrid1.Rows[IntPriI].Cells[12].Controls[0];
HyperLinkObj.Text = "";
}

Value from row with DropDownList on DropDownList Index Changed Event

Code:
<asp:GridView ID="gv_Recruit" AutoGenerateColumns="False" Width="100%"
runat="server" OnRowCreated="gvStates_RowCreated"
OnRowDataBound="gvStates_RowCreated">
<Columns>
<asp:BoundField HeaderText="key" DataField="key" />
<asp:BoundField HeaderText="Name" DataField="Name" />
<asp:BoundField HeaderText="Quota" DataField="Quota" />
<asp:BoundField HeaderText="Session" DataField="Sess" >
<ItemStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:DropDownList ID="ddlCities" Width="100%" AutoPostBack="true" runat="server" OnSelectedIndexChanged="ddl_selected">
</asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="Recruiter" DataField="Recruiter" />
<asp:BoundField HeaderText="MN Phone" DataField="MN Phone" />
<asp:BoundField HeaderText="Cell Phone" DataField="Cell Phone" />
</Columns>
</asp:GridView>
Code Behind:
protected void ddl_selected(object sender, EventArgs e)
{
string _dd_value = ((DropDownList)sender).SelectedValue;
string trying_to_get = gv_Recruit.Rows[???].Cells[0].Text.ToString();
string also_tried = gv_Recruit.SelectedRow.Cells[0].Text.ToString();
}
Basically what I'm trying to do is get the key value from the first row when the drop down is changed so I can perform an update ???
Can't figure this out.
Thanks in advance for the help...
Try
GridViewRow gRow = (GridViewRow)(sender as Control).Parent.Parent;
string trying_to_get = string.Empty;
if (gRow != null)
{
trying_to_get = gRow.Cells[0].Text;
}

asp.net Gridview: buttons accessing data for each row

I'm trying to code a Gridview that has a button on each row that when clicked will expose that particular rows data for use, but I'm not sure how the data would be passed.
The Gridview:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ID"
DataSourceID="SqlDataSource2">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True"
SortExpression="ID" Visible="False" />
<asp:BoundField DataField="RelationID" HeaderText="RelationID" InsertVisible="False"
SortExpression="RelationID" Visible="False" />
<asp:BoundField DataField="UserRole" HeaderText="UserRole" InsertVisible="False"
SortExpression="UserRole" Visible="False" />
<asp:BoundField DataField="FirstName" HeaderText="First Name" SortExpression="FirstName" />
<asp:BoundField DataField="Surname" HeaderText="Surname" SortExpression="Surname" />
<asp:BoundField DataField="Telephone" HeaderText="Telephone" SortExpression="Telephone" />
<asp:BoundField DataField="Email" HeaderText="Email" SortExpression="Email" />
<asp:BoundField DataField="Hash" HeaderText="Hash" InsertVisible="False" SortExpression="Hash"
Visible="False" />
<asp:BoundField DataField="DateCreated" HeaderText="Date Invited" SortExpression="DateCreated" />
<asp:TemplateField HeaderText="Resend Welcome Email">
<ItemTemplate>
<asp:Button runat="server" ID="btnResend" Text="Resend" OnClick="btnResend_Click" />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
</asp:TemplateField>
</Columns>
</asp:GridView>
The button_OnClick
protected void btnResend_Click(object sender, EventArgs e)
{
bool boolEmailSent = Email.sendWelcomeEmail(//Email from Row, //FirstName from Row, //Surname from Row, //Hash from Row);
if (boolEmailSent == true)
{
//Confirm to User
}
else
{
//TODO: write error to log
}
}
