Page.FindControl for not a full name

Can I find a control using Page.FindControl() if I don't know the full name? I know only part of it, this part is unique, so it won't appear in any other control id.

Haven't tested it, just a thought:

Loop through the controls

Public Function FindControls(ByVal parent As Control) As Control
For each ctrl As Control In parent.Controls
  If ctrl.ID.IndexOf("YOUR PART OF ID") > -1 Then
    return ctrl
    Exit Function
  End If
  If ctrl.HasControls Then
  End If
return Nothing
End Function

maybe still some errors, but it's a first thought

I actually started from this iteration, but apparently in my case it's a bit more complicated as I have not asp-control table on my page, where among other controls, asp and html ones, I have my control. So, it should be more thorough iteration first (checking for not asp controls as they can through exceptions), and second I would use it only if I can't find a way to twick this FindControl function.

I guess I'll have to iterate after all...

kG, your function is actually not recursive... it will return the first control that has a matching ID and terminate the recursion on that. If I have my control not first, it will not pick it up.

I found a simple way to work out this by using a few if-elses, but still need to do recursion to reset attributes of all controls of this type to default values.

I've done it some time ago already but never had time to get back to the question. Thank you for your input.
