Attach a Click Event for the LinkButton which is placed in the ItemTemplate and access the Row like

protected void LinkButton1_Click(object sender, EventArgs e)
{
        LinkButton lb = (LinkButton)sender;
        GridViewRow row = (GridViewRow)lb.NamingContainer;
}

{    
// here gridview gv.     
    int id = Convert.ToInt32(gv.DataKeys[e.RowIndex].Values[0].ToString());
    string name = ((TextBox)gv.Rows[e.RowIndex].FindControl("txtname")).Text;
    string dstn = ((TextBox)gv.Rows[e.RowIndex].FindControl("txtdstn")).Text;
    string add = ((DropDownList)gv.Rows[e.RowIndex].FindControl("ddladd")).Text;

Use RowCommand Event for that.

Eg in .aspx page:

ASP.NET

<asp:templatefield headertext="Link" xmlns:asp="#unknown">
            <itemtemplate>
                <asp:linkbutton id="LinkButton1" runat="server">
CommandName ="Link">LinkButton</asp:linkbutton>
            </itemtemplate>
            </asp:templatefield>

In .CS page:C#

C#

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
         if (e.CommandName == "Link")
            {
                LinkButton img = (LinkButton)e.CommandSource as LinkButton;
                GridViewRow row = img.NamingContainer as GridViewRow;

                Label lbid = (Label)row.FindControl("label1");//Label ID
                int  id = Convert.ToInt32(lbid.Text);

            }
     }

VB:

VB

Protected Sub GridView1_RowCommand(sender As Object, e As GridViewCommandEventArgs)
    If e.CommandName = "Link" Then
        Dim img As LinkButton = TryCast(DirectCast(e.CommandSource, LinkButton), LinkButton)
        Dim row As GridViewRow = TryCast(img.NamingContainer, GridViewRow)

        Dim lbid As Label = DirectCast(row.FindControl("label1"), Label)
        'Label ID

        Dim id As Integer = Convert.ToInt32(lbid.Text)
    End If
End Sub

Solution 6

try this:-

XML

<asp:TemplateField HeaderText="Link">
<ItemTemplate>
<asp:ImageButton ID="imgbtnLinked" CommandName="Link" CommandArgument='<%# Eval("Bank_TrxID") %>'runat="server" ImageUrl="~/Images/linkbtn.png" ToolTip="Link" Width="12px" />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>

in backend (change your code as per your requirement):-

VB

Protected Sub Gridview1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles Gridview1.RowCommand
Dim row As GridViewRow = DirectCast(DirectCast(e.CommandSource, Control).NamingContainer, GridViewRow)
Dim str As String = row.Cells(1).Text   //Change your cell index.
End Sub

hope it hepls.

@Goenitz I too did the same mistake.sorry for that

Goenitz 29-Jan-14 1:15am

Dont worry about it :)

TrushnaK 29-Jan-14 2:28am

you want exact answers..
don't you want to take any efforts yourself..

Dim row As GridViewRow = DirectCast(DirectCast(e.CommandSource, Control).NamingContainer, GridViewRow)
Dim str As String = row.Cells(1).Text

this two lines solves your problem..

Goenitz 29-Jan-14 3:14am

You can use GridView.RowCommand Event[^] for this.

So, declare it inside GridView.

ASP.NET

<asp:GridView ID="grdYourGridView" runat="server" OnRowCommand="GridViewCommandEventHandler" />

Now declare CommandName and CommandArgument properties inside LinkButton.

ASP.NET

<asp:LinkButton ID="lnkSomeLinkButton" 
                runat="server" 
                CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" 
                CommandName ="SomeCommandName">LinkButtonText</asp:LinkButton>

Now, in .cs page, write the Event Handler like...

VB

Sub ProductsGridView_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)

    ' If multiple buttons are used in a GridView control, use the
    ' CommandName property to determine which button was clicked.
    If e.CommandName = "SomeCommandName" Then

      ' Convert the row index stored in the CommandArgument
      ' property to an Integer.
      Dim index = Convert.ToInt32(e.CommandArgument)

      ' Retrieve the row that contains the button clicked 
      ' by the user from the Rows collection.
      Dim row = grdYourGridView.Rows(index)

      Dim someBoundFieldValue As String = row.Cells(CellIndex).Text

    End If

  End Sub
