The code below creates a button, but because I MUST modify the page, the QueryStringState is missing the pid. What I have below would add the PageId, but since it is a string, I get an error, "cannot implicitly convert from string." <BR><BR> XmlQueryStringAction cancelled = new XmlQueryStringAction("CancelThis", Estrada.Rendering.QueryStringState.Current[UnitId]));<BR><BR>commands.Add(cancelled);<BR><BR>I tried using a String Reader, and passing that in, but to no avail. <BR><BR>I also tried converting to XMLActionType and to XMLQueryStringAction.<BR><BR>Any ideas?
