Never access the controls collection in Page_Init or Page_PreInit with declarative data-binding in ASP.NET 2.0
If you have a GridView, DataGrid, DetailsView, FormView, DataList or Repeater bound using DataSourceID you should never touch the controls collection in Page_Init or Page_PreInit. If you do this your declarative data-binding will be lost on any outside of the control post-back. How to check this?Example:aspx<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title>Untitled Page</title></head><body> <form id="form1" runat="server"> <asp:Button ID="Button1" Text="Button1" runat="server" /> <asp:GridView ID="GridView1" AllowPaging="true" DataSourceID="AccessDataSource1" runat="server"> </asp:GridView> <asp:DetailsView ID="DetailsView1" DataSourceID="AccessDataSource1" AllowPaging="true" runat="server"> </asp:DetailsView> <asp:FormView ID="FormView1" DataSourceID="AccessDataSource1" AllowPaging="true" runat="server"> <ItemTemplate> ProductID : <%# Eval("ProductID") %> </ItemTemplate> </asp:FormView> <asp:DataList ID="DataList1" DataSourceID="AccessDataSource1" runat="server"> <ItemTemplate> ...June 25, 2007 -
Web ASP.NET AJAX
Firewalls breaking ASP.NET AJAX!
This one is serious and may bite you any time. Yesterday Shaun posted this problem in our forums: he and his users were experiencing odd errors when requesting ASP.NET AJAX-based sites, and yes, that means RadControls "Prometheus" based ones as well. Partial rendering requests initiated by UpdatePanel controls failed with the cryptic message: ============== Sys.WebForms.PageRequestManagerParserErrorExeption: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near '<!DOCTYPE html P''. ============== Of course all that comes without any trace of Response.Write(),...June 25, 2007 -

RadEditor for MOSS; Telerik RadControls for MOSS
When we released the RadEditor Lite for MOSS a few months back, customers immediately contacted us and clearly stated that they need a rich-text editor that was not limited only to the features that are available in the Microsoft's default MOSS editor. People not only required a cross-browser editing experience but also demanded ALL the capabilities of RadEditor in MOSS. So, after a few months of preparations and development, I'm really excited to make a few announcements: 1. RadEditor for MOSS is finally here! You can find more information here: http://www.telerik.com/products/sharepoint/overview.aspx. You can also find a comparison between the Lite and the...June 18, 2007 -

How to: Optimize RadCombobox Ajax
One of the nice things about attending conferences like TechEd is all of the direct feedback you get from Telerik "fans" (people that use the RadControls everyday and love them). These fans love to use the RadControls and they also love to push the controls to their limits. That often leads to some interesting questions, such as this one I was presented with at the Telerik booth:"Is it possible to delay the RadCombobox autocomplete callback until a certain number of characters have been typed? Or is it possible to delay the callback so that it doesn't start until users stop...June 18, 2007
