Question

In my application i am using a GridView and i am adding an onlick attribute to the GridView through the following Code..

  Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)


    If e.Row.RowType = DataControlRowType.DataRow Then
        e.Row.Attributes("onclick") = Page.ClientScript.GetPostBackClientHyperlink(GridView1, "Select$" & e.Row.RowIndex.ToString())
    End If

When someone selects a row in the Grid view, i want the GridView to get disabled and not allow any other selections unless the user presses a button. I tried using

GridView1.Enabled = false

But still the user is able to select a row.

How can i disable the GridView Selection ??

Answer 1

Since you are selecting a row by the above code the easiest fix would be to check if selected index is not equal to -1 (meaning a row has been selected) in the row databound event.

If GridView1.SelectedIndex = -1 Then
    If e.Row.RowType = DataControlRowType.DataRow Then
        e.Row.Attributes("onclick") = Page.ClientScript.GetPostBackClientHyperlink(GridView1, "Select$" + e.Row.RowIndex.ToString())
    End If
End If

and to reattach the selecting code on the click of a button you can just set the selectedIndex to -1 and rebind the gridview in the button click event.
