Hi,

I have a LinkButton in a TemplateField inside my GridView
How do I access this control in the RowDataBound handler?

I've tried this:

Dim LinkEdit As LinkButton
If e.Row.RowType = DataControlRowType.DataRow Then
LinkEdit = e.Row.FindControl("LinkEdit")
LinkEdit.CausesValidation="true"
End If

but it I get the error "Object reference not set to an instance of an
object"

Hi,

that should be somewhat right assuming LinkButton has ID "LinkEdit" and it's
not inside EditItemTemplate (except that if you have it declaratively there,
you might want to set CausesValidation already at that point, in aspx, to
avoid unnecessary state to be kept in ViewState,l when possible)

Can you show how you have declared the TemplateField?
