First of all, you should not be setting Text in Render(). (It should
not change any property)
Render really wants to be something like:
protected override void Render(HtmlTextWriter output)
{
string myhtml = ReportUIClassLibrary.BizObjects.GeneratePrompts(Te xt,
MoreText);
output.Write(myhtml);
}
Then in your webpage's codebehind:
WC1.Text = Request.QueryString["dbid"];
WC1.MoreText = Request.QueryString["reportid"];
Actually, you'll probably want to create properties called DbId & ReportId
instead of Text & MoreText
