While working with one web application I was adding some controls from telerik and this message appears:
"The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases. "
The application came normal when I remove the tag <telerik:RadComboBox ID="TESTE" runat="server"></telerik:RadComboBox>.
What is the problem?
Thanks in advance.
