I want to find dynamic controls. Example: - In my aspx:
<table id='vertragstypPVN_<%# Eval("Vertragstyp") %>' style="display: none" runat="server">
Table Ids will be generated like: vertragstypPVN_Test1, vertragstypPVN_Test2, etc.
Since you generate the dynamic tables yourself, you already have a list of all the names that you have used. Use the Forms Collection to loop through all the tables and do a compare to hit to the right table.
