Alternatively you could disable the ServerForm/Event-validation on the page that is rendering the control to a string.

The following example illustrates how to do this.

 public override void VerifyRenderingInServerForm(Control control)
{ /* Do nothing */ }

public override bool EnableEventValidation
{
get { return false; }
set     { /* Do nothing */}
}
