  yeah. The button too. I see "Index was out of range." indicate the code executed with wrong value. Use btn in itemtemplate, not btnfield.

  Pass itemindex to button eventargument

  <Columns>
                  .
                  .
                  .
                  <asp:TemplateField>
                      <ItemTemplate>
                          <asp:Button ID="Button1" runat="server" Text="Button"
                          commandname="Button1Command"
                          CommandArgument='<%# Container.DataItemIndex %>' />
                      </ItemTemplate>
                  </asp:TemplateField>
              </Columns>

  if (e.CommandName=="Button1Command")
  {
  GridViewRow row =
         ((System.Web.UI.WebControls.GridView)(sender)).Rows[int.Parse(e.CommandArgument.ToString())];
  
  string idString = row.Cells[0].Text;
  int id = Convert.ToInt32(idString);
  }

  
  
  Sorry for changing code, no problem with your code.

  Add if condition to your code to make sure only the button will execute the code. Without IF condition, your code will be executed by all rowcommands.

  Hi,

  Thanks again for the response, and for sticking with this.

  I have implemented your code as an ImageButton (as I would like to use an Image for the button), like so:

  <asp:TemplateField>
  	<ItemTemplate>
  		<asp:ImageButton ID="addToQuoteButton" runat="server" ImageUrl="~/assets/images/buttons/addtocart_small.gif"
  			CommandName="adToQuoteButtonCommand" CommandArgument='<%# Container.DataItemIndex %>' />
  	</ItemTemplate>
  </asp:TemplateField>

  and here's the new code in CodeBehind:

  protected void listProductsGridView_RowCommand(object sender, GridViewCommandEventArgs e)
  {
  	if (e.CommandName == "adToQuoteButtonCommand")
  	{
  		GridViewRow row = ((System.Web.UI.WebControls.GridView)(sender)).Rows[int.Parse(e.CommandArgument.ToString())];
  	string idString = row.Cells[0].Text;
  	int id = Convert.ToInt32(idString);

  I am NOW getting an error with a different piece of code:

  protected void listProductsGridView_RowCreated(Object sender, GridViewRowEventArgs e)
  {
  	if (e.Row.RowType == DataControlRowType.DataRow)
  	{
  		ImageButton addButton = (ImageButton)(e.Row.Cells[5].Controls[0]);
  		addButton.CommandArgument = e.Row.RowIndex.ToString();

  The error is:

  Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.ImageButton'.

  **********

  Any ideas?

  GridViewRow row =(GridViewRow)listProductsGridView.Rows[int.Parse (e.CommandArgument.ToString())];

  oned_gk.

  I assume this code was to replace the same in "RowCommand"?

  Doing so leaves me with the same error in RowCreated.

  Ideas?

  The error is here:

  protected void listProductsGridView_RowCreated(Object sender, GridViewRowEventArgs e)
  {
  	if (e.Row.RowType == DataControlRowType.DataRow)
  	{
  		ImageButton addButton = (ImageButton)(e.Row.Cells[5].Controls[0]);
  		addButton.CommandArgument = e.Row.RowIndex.ToString();

  I haven't changed this code at all since it worked well with the ButtonField code we have now changed into a TemplateField containing an ImageButton.

  You probably added a pager template to the gridview at some point and it is blank.  You won't see the pager at all if it is blank regardless of the other settings.  You have to delete your pager template to get it to go back to the built-in pager style.
