I have a web application that I'm writing. I have a lot of buttons, all named the same thing except with a number appended (button1,button2,button3...etc.). All of these are in a panel named Panel3. I would like to loop through these blank ImageButtons and set their image using .ImageUrl. I know my getIconImage() function works.
Dim cntrl As Control
For Each cntrl In Me.Panel3.Controls
cntrl.ImageUrl = getIconImage(4)
Next
The problem is "cntrl" does not recognize .ImageUrl as an option. It is like it doesn't recognize itself as an ImageButton. I am using asp.net and vb.net. Thanks!
(as a note: I have also tried "Me.Controls" with no such luck. Also, I have tried setting a temporary ImageButton object equal to "cntrl" and modifying the .ImageUrl from there.)
You don't say what the issue is so i'll assume you need to check which type of control you are getting in the loop:
Dim cntrl As Control
For Each cntrl In Me.Panel3.Controls
if TypeOf cntrl Is ImageButton Then
cntrl.ImageUrl = getIconImage(4)
End if
Next
Try this:
For Each cntrl As ImageButton In Me.Panel3.Controls.OfType(Of ImageButton)
May have to do Imports System.Linq
