For those playing the home version, I was able to find a solution to the
problem. I still don't understand why my previous idea didn't work (and not
having received any responses I guess I will have to continue wondering),
but this is what I did to get it to work:
Protected Sub ShowScores(ByVal sender As System.Object, ByVal e As
System.EventArgs)
.....
' Cast the sender object
LButton = DirectCast(sender, LinkButton)
' From the Button's level, go up to the DataList control
' Parent.Parent because the first Parent is the DataListItem, the
second is the DataList
' Run through the list and enable each button
For i As Int16 = 0 To (LButton.Parent.Parent.Controls.Count - 1)
DirectCast(LButton.Parent.Parent.Controls.Item(i). Controls.Item(1),
LinkButton).Enabled = True
Next
' Now disable the button that was clicked
LButton.Enabled = False
.....
End Sub
