GridView DataRowBound question

[pvong]

Doing this in VB.NET with VS2008.

I have a simple GridView with two columns. Column1 Header is called
"Reason" and the rows contain a Label called "ReasonL". Column2 header is
called Add/Edit and the row has a LinkButton called "AddEditLB" . Basically,
it looks like this.

Reason Add/Edit
ReasonL AddEditLB

All I want to do is make AddEditLB Text to say "Add" if ReasonL is
string.empty and "Edit" if it's not. This is what I tried in the
RowDataBound event and it didn't work:

Protected Sub GridView1_RowDa taBound(ByVal sender As Object, ByVal e As
System.Web.UI.W ebControls.Grid ViewRowEventArg s) Handles
GridView1.RowDa taBound

If e.Row.RowType = DataControlRowT ype.DataRow Then
If e.Row.DataItem( "ReasonL").ToSt ring = String.Empty Then
e.Row.DataItem( "AddEditLB" ) = "Add"
Else
e.Row.DataItem( "AddEditLB" ) = "Edit"
End If
End If

End Sub

Can someone tell me what I did wrong?
This is the error msg I got.

ReasonL is neither a DataColumn nor a DataRelation for table DefaultView.

Thanks!

e.Row.DataItem( "AddEditLB" ) = "Add"

What happens if you try:

e.Row.Cells(2). Text = "Add"

Mark - This does work, but it only puts the word "Add" or "Edit" in my
column where I had my AddEdit LinkButton. It's just text and no LinkButton.
I want to assign the text for the LB in each row. My users need to have
access to the LB.

OK, then. How about:

DirectCast(e.Ro w.Cells(2).Find Control("AddEdi tLB"), Button).Text = "Add"

The syntax may not be 100% accurate, as I never go anywhere near VB.NET, but
should be close enough...

Re: GridView DataRowBound question

This worked perfectly. Now I need to do some reading on what DirectCast
actually does. Learned something new today. Thanks!
