Hi all,
I have gridview1 with template columns.
In one of the columns I have gridView2 with template columns too. In the edittemplate, gridview2, I have a button (insertDateCodeButton) and I want to set the commandArgument of that button to e.Row.RowIndex. How do I "find" insertdateCodeButton?
I am using:

Protected Sub GridView2_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)

        If e.Row.RowType = DataControlRowType.DataRow Then

            If e.Row.RowState = DataControlRowState.Edit Then
               
            CType(e.Row.FindControl("addNewDateCodeButton"), Button).CommandArgument = e.Row.RowIndex
               
            End If

        End If

End Sub

The if statement is true for only row number:0,2,4 , etc... How do i get the alternate rows?
Thank you !

yeah MS dropped the ball on this one, you have to do a bit check to see if the alternate row is in an edit state. The snippet below works for all rows
 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if ((e.Row.RowType == DataControlRowType.DataRow) && ((e.Row.RowState & DataControlRowState.Edit) > 0))
            {
                Button btn = (Button)e.Row.FindControl("insertDateCodeButton");
                btn.CommandArgument = e.Row.RowIndex.ToString();
                btn.Text = e.Row.RowIndex.ToString();
            }
        }

Thank you wht1986,

"e.Row.RowType == DataControlRowType.DataRow) && ((e.Row.RowState & DataControlRowState.Edit) > 0))" is the same as what I already have (in vb.net):
" If e.Row.RowType = DataControlRowType.DataRow Then
            If e.Row.RowState = DataControlRowState.Edit Then " 
Am I missing something?

it's not the same, look at the code

(e.Row.RowState & DataControlRowState.Edit) > 0

is a bitwise compare

the problem is on alternate rows, the row state is actually a combination of edit and alternate row states, so what the above statement does is looks at the bit mask for just the edit portion to see if it is set

I converted your c# code wrongly to vb.net.

But now it works:

If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then
      CType(e.Row.FindControl("addNewDateCodeButton"), Button).CommandArgument = e.Row.RowIndex
End If

Thank you!!!!!!

Here's the VB.NET Version
    Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If ((e.Row.RowType = DataControlRowType.DataRow) And ((e.Row.RowState And DataControlRowState.Edit) > 0)) Then
            Dim btn As Button = e.Row.FindControl("insertDateCodeButton")
            btn.CommandArgument = e.Row.RowIndex.ToString()
            btn.Text = e.Row.RowIndex.ToString()
        End If
    End Sub
