Hi,
I am trying to check a value of a contril in my gridview but this %$%&^^&*
thing is driving me nuts.

I tried

Dim t As TextBox = CType(e.Row.Cells(16).FindControl("Status"), TextBox)
If t.text = "N" Then
e.Row.Cells(16).Controls(1).Visible = True
End If

This crap doesn't work. I get either Object not set to instance BS or can
cast from literal to system.web.ui crap.

The column is a template column with 2 controls, one label control and
another is a checkbox. I want to set the checkbox to visible only when the
label control says "N" and at the same time make the label contril visible =
flase.

Please assist.

Thanks

I'm not surprised! The above code is indeed crap - I suggest you fire the
idiot who wrote it...

The main problem, of course, is that the cell in question contains a Label
control which the above code is trying to CType to a TextBox...

Dim l As Label = CType(e.Row.Cells(16).FindControl("Status"), Label)
If l.Text = "N" Then
e.Row.Cells(16).Controls(1).Visible = True
e.Row.Cells(16).Controls(0).Visible = False
End If

The code is similar to yours except it was tried against a text box as well.
Even with yours didn't work. Eventually adding .Trim() worked! Pardon my
frustration.

Dim t As TextBox = CType(e.Row.Cells(16).FindControl("Status"),
TextBox)
If t.text.Trim() = "N" Then
e.Row.Cells(16).Controls(1).Visible = True
End If
