I am trying to use MessageDisplay.aspx to present a user friendly message to the user when an exception occurs. It works fine until I changed MessageDisplay.aspx to use a Master Page. I thought that would be a reasonable thing to do.

The first problem I had was with the following code in mmMessageDisplay.DisplayPage():

this.DisplayPage((Label)this.FindControl("lblHeader"),
(Label)this.FindControl("lblMessage"),
(Label)this.FindControl("lblRedirectHyperLink"));

This was not finding the controls because of the Master Page. I changed the code to the following, which now works okay:

this.DisplayPage((Label)this.Master.FindControl("MainContent").FindControl("lblHeader"),
(Label)this.Master.FindControl("MainContent").FindControl("lblMessage"),
(Label)this.Master.FindControl("MainContent").FindControl("lblRedirectHyperLink"));

Once I got past the above issue, I ran into another problem that I am really struggling to resolve. I now get an exception saying “A page can have only one server-side Form tag.”

If I run the same test with debugging, I get an exception saying "Error executing child request for /LendRite/MessageDisplay.aspx." This exception occurs on the following line in mmMessageDisplay.DisplayMessage():

Context.Server.Transfer(mmWebDataHelper.GetFilePath("/" + templatePageName));

As always, any help would be appreciated.

Thanks,

Al
