I am trying to calculate the sum of the grand total column and showing it to the footer of the gridview, which I am able to achieve it. However I have a condition which makes some rows invisible from the gridview, but it is also summing the value of the rows which are invisible. How to sum the column value only for the rows which are visible?
Below is my gridview:
<asp:GridView ID="GridView9" runat="server" AllowPaging="false" AutoGenerateColumns="False"
ShowFooter="true" BackColor="White" DataKeyNames="ID" BorderColor="#999999" CssClass="tableUserInfo"

<AlternatingRowStyle BackColor="#CCCCCC" />
<Columns>
<asp:TemplateField HeaderText="SessionId" Visible="true">
<ItemTemplate>
<asp:TextBox ID="txt_GSessionId" runat="server" Text='<%# Eval("SessionId") %>' ReadOnly="true"
Visible="false"></asp:TextBox>
</ItemTemplate>
<HeaderStyle Width="10%" />
<ItemStyle Width="10%" />
</asp:TemplateField>
<asp:TemplateField HeaderText="Customer" Visible="true">

</Columns>
<FooterStyle BackColor="Black" ForeColor="Red" Width="100%" Wrap="false" />
<HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
</asp:GridView>
Here is my code behind:
decimal grdTotal;
protected void GridView9_RowDataBound(object sender, GridViewRowEventArgs e)
{
txt_SessionId.Text = ddlSession.SelectedValue;
foreach (GridViewRow row2 in GridView9.Rows)
{
TextBox sid = row2.FindControl("txt_GSessionId") as TextBox;
int a, b;
a = int.Parse(sid.Text);
b = int.Parse(txt_SessionId.Text);
if (a == b)
{
row2.Visible = true;
}
else
{
row2.Visible = false;
}
}
if (e.Row.Visible && e.Row.RowType == DataControlRowType.DataRow)
{
decimal rowTotal = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "GTotal"));
grdTotal = grdTotal + rowTotal;
}
if (e.Row.RowType == DataControlRowType.Footer)
{
Label lbl = (Label)e.Row.FindControl("lblTotal");
Label lbl1 = (Label)e.Row.FindControl("lblLabourTotal");
lbl.Font.Size = 12;
lbl.Text = "Rs. " + grdTotal.ToString("0");
lbl.ForeColor = System.Drawing.Color.White;
}
}
I have tried several so called answers for this and it has me lost. I am simply trying to default a TextBox Text value with today's date and time, but I cannot find the control when I click LinkButton with CommandName "Edit".
Here is my gridview...

The LinkButton btnEDT works and puts the gridview in edit mode. But in code behind I cannot find "txtReturned".
This is what I've tried so far...
protected void gvSignInRegister_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Edit")
{
int rowIdx = Convert.ToInt32(e.CommandArgument);
GridViewRow row = gvSignInRegister.Rows[rowIdx];
if (row != null && row.RowType == DataControlRowType.DataRow)
{
TextBox tb = (TextBox)row.FindControl("txtReturned");
if (tb != null) tb.Text = DateTime.Now.ToString("dd/MM/yyyy HH:mm");
//I've tried this too but it does not work. Interestingly, it does not crash, so cells[4] must exist!
//row.Cells[4].Text = DateTime.Now.ToString("dd/MM/yyyy HH:mm");
}
}
}
For some reason the rowIdx is always 0. Why? I thought a row index of 0 meant the header of the gridview control.
I've also tried using the NamingContainer that most other people have suggested in other posts, but that returns a blank (I suspect new?) GridViewRow.
ie
GridViewRow row = (GridViewRow)((GridViewRow)(e.CommandSource).NamingContainer);
UPDATE
I found this, which is exactly the problem I am having, but the solution via the RowEditing still does not find the textbox!
However the RowDataBound() solved it! Read my answer below.
The answer was in getting into the editmode version of the GridView itself and then find the control!
As per this post...
<asp:GridView ID="gvSignInRegister" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" CellPadding="3"
DataSourceID="sdsSignInRegister" ForeColor="Black" BackColor="White" BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" GridLines="Vertical" OnRowDataBound="gvSignInRegister_RowDataBound">
<Columns> ...etc...
protected void gvSignInRegister_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if ((e.Row.RowState & DataControlRowState.Edit) > 0)
{
TextBox tb = (TextBox)e.Row.FindControl("txtReturned");
if (tb != null) tb.Text = DateTime.Now.ToString("dd/MM/yyyy HH:mm");
}
}
}
Use Container.DisplayIndex instead of Container.DataItemIndex
But I dont think you will get textBox control if you are placing it in EditItemTemplate
If your expectation is editing operation then please use the below code

decimal.TryParse(txtQty.Text, out qty);
if (qty < 0)

lblErrorSummary.InnerText = "Please provide valid Quantity";

itemList[e.RowIndex].Quantity = qty

I have a little problem when I go to my gridview in website my button for row command doesn't work. I don't know why.
This is my code for the page:
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Ver")
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow selectedRow = GridView1.Rows[index];
Session["Imagem"] = GridView1.DataKeys[index]["Imagem"];
Session["Nome"] = GridView1.DataKeys[index]["Nome"];
Session["Preço"] = GridView1.DataKeys[index]["Preço"];
Session["Descricao"] = GridView1.DataKeys[index]["Descricao"];
Session["Categoria"] = GridView1.DataKeys[index]["Categoria"];
Session["id"] = GridView1.DataKeys[index]["Id"];
Session["estado"] = GridView1.DataKeys[index]["estado"];
GridView1.DataBind();
Response.Redirect("Detalhes.aspx");
}
}
And my gridview markup is this:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="Imagem ,Nome,Preço,Descricao,Categoria,id,estado"
DataSourceID="SqlShop" OnRowCommand="GridView1_RowCommand"

</asp:GridView>
<asp:SqlDataSource ID="SqlShop" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [Produtos]">
</asp:SqlDataSource>
Command name is incorrect in the C# code
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Select") //this part
{
int index = Convert.ToInt32(e.CommandArgument);
...
...
Response.Redirect("Detalhes.aspx");
}
}
Or
You can change the values ButtonField parameters as
<asp:ButtonField ButtonType="Button" CommandName="ver" Text="Select" />
I am not getting the point why this is happening.
I have a Gridview, inside that I have implemented a pagerTemplate. It is showing me the correct records which are coming from the database.
First of All, I took the logic of implementing the gridview pager part from here. And I implemented the same as described their.
Now the scenario which I came up with is that, When I change the dropdown selection, my gridview gets postback and all the Row of the grid gets disturbed. I dont know why this is happening.
See the code which I implemented:-
<asp:GridView ID="grdCSRPageData" runat="server" Width="100%" border="1" Style="border: 1px solid #E5E5E5;" CellPadding="3"
AutoGenerateColumns="False" OnDataBound="grdCSRPageData_DataBound" AllowPaging="true" CssClass="hoverTable" EmptyDataText="No Records Found"
OnPageIndexChanging="grdCSRPageData_PageIndexChanging" DataKeyNames="Id" OnRowDeleting="grdCSRPageData_RowDeleting"

<Columns>
<asp:TemplateField HeaderText="Select" HeaderStyle-Width="5%" HeaderStyle-CssClass="k-grid td">

<asp:CheckBox ID="chkSelect" runat="server" AutoPostBack="false" />

</asp:TemplateField>

<td style="width:70%; text-align:right">
<asp:label id="CurrentPageLabel" runat="server"/>
</td>
</td>
</tr>
</table>
</pagerTemplate>
</asp:GridView>
The code is added with PagerTemplate. Also see my code behind as given their:-
Cs Code for the PagerTemplate:-
protected void grdCSRPageData_DataBound(object sender, EventArgs e)
{
GridViewRow pagerRow = grdCSRPageData.BottomPagerRow;
DropDownList pageList = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");
Label pageLabel = (Label)pagerRow.Cells[0].FindControl("CurrentPageLabel");
if (pageList != null)
{
for (int i = 0; i < grdCSRPageData.PageCount; i++)
{
int pageNumber = i + 1;
ListItem item = new ListItem(pageNumber.ToString());
if (i == grdCSRPageData.PageIndex)
{
item.Selected = true;
}
pageList.Items.Add(item);
}
}
if (pageLabel != null)
{
int currentPage = grdCSRPageData.PageIndex + 1;
pageLabel.Text = "Page " + currentPage.ToString() +
" of " + grdCSRPageData.PageCount.ToString();
}
}
protected void PageDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow pagerRow = grdCSRPageData.BottomPagerRow;
DropDownList pagelist = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");
grdCSRPageData.PageIndex = pagelist.SelectedIndex;
}
Please help. Any help would be appreciable
try changing the AutoPostBack="true" to false of your dropDownList and be sure to load data in Page_Load inside
if (!IsPostBack){
//bind gridview
}
update
try inserting your dropDownList (with AutoPostBack="true") and your GridView inside an UpdatePanel with "UpdateMode=Conditional" like this
<asp:UpdatePanel runat="server" ID="up1" UpdateMode="Conditional">
<ContentTemplate>
//put here gridview
<ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="PageDropDownList" EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
update

When a Button in the GridView is clicked I can't seem to get the row index or the row that is to be eliminated, I need the Id and the Complete route of the archive, both of them are on the bound fields of the GridView, here is the code I have:

I have tried various methods found here on StackOverflow, hope you guys can help me. Thanks.
Instead of using .Parent.Parent, I recommend using the CommandArgument property of the ImageButton and set the dataitem's Id.
Here is another post on StackOverflow that give a good bit of code: ASP.NET GridView RowIndex As CommandArgument
It appears to me that all you need is the Id of the data you want to delete. So instead of trying to use the row's index, just put the Id in the button's CommandArgument
Example:
<asp:ImageButton ID="ImgDelete"
runat="server"
CommandArgument="Delete"
ImageUrl="~/Images/page_delete.ico"
OnClick="btnEliminar_Click"
CommandArgument='<%#Eval("Id")%>'
OnClientClick="return confirm('¿Esta seguro de eliminar este archivo?');"
ToolTip="Borrar Documento"/>
Code Behind:
protected void btnEliminar_Click(object sender, EventArgs e)
{
try
{
Int64 intId = 0;
ImageButton btn = (sender as ImageButton)
if(btn != null)
{
Int64 tempId;
if(Int64.TryParse(btn.CommandArgument, out tempId))
{
intId = intId;
/*Other part of the code*/
}
}
}
catch(Exception)
{
/*Other part of the code*/
}
}
