Web Resources demystified: Part 3 (Troubleshooting)
In this post I will show you how to troubleshoot Web Resource related problems and how to deal with them. If you are using an ASP.NET server control with rich client-side behavior it is likely built to utilize web resources. Sometimes your page loads and that rich server side control does not work at all - the tree view does not expand, the grid cannot sort etc. Most of the times this is because the JavaScript files of those controls have failed to load. If your browser is configured to prompt on JavaScript errors you may see the following error messages: "RadTreeView... -

RadRotator binding to XML data
As you already know, the upcoming RadControls for ASP.NET AJAX Q2 2008 release will add a new control to the suite - the RadRotator. If you are familiar with the RadRotator control from the classic ASP.NET controls suite, you will be glad to know that it is now included in the new Ajax suite as well.

She has prepared a short list of tips and tricks based on some recurring questions that we have noticed over time. The original tips&tricks list had 12 entries, but some of the solutions were eventually built into the RadToolTip code, so it was reduced to 7 :) We hope this post will be useful to all who try to combine the tooltip with other RadControls and use it in more advanced scenarios that are not always covered in... -

Page Request Manager Parser Error with ASP.NET AJAX 1.0
How many times you get this in your ASP.NET AJAX 1.0 applications? After several support tickets we manage to isolate this to very simple case - standard UpdatePanel and a Button writing in Session. How weird? Here is the code: <%@ Page Language="VB" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <script runat="server"> Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Page.Session("test") = "test" End Sub </script> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body>...
