As far as I can tell from the experience of my colleagues with RadControls for ASP.NET AJAX, one of the common feature requests for RadComboBox and RadTreeView is combining them into one piece. Recently we started to receive similar requests for RadComboBox and RadTreeView for Silverlight. Placing a TreeView in a ComboBox sometimes makes a lot of sense, so I decided to research the best way to do it.   The first, the simplest and most obvious way is to place a RadTreeView as content of RadComboBox: <input:RadComboBox> <nav:RadTreeView  ItemTemplate="{StaticResource ItemTemplate}"  ItemsSource="{StaticResource ItemsSource}" /></input:RadComboBox> This works, but it has one important limitation: RadComboBox cannot...

Did you know that if your user agent string is more than 260 characters in length then your user agent string suddenly and almost magically becomes “Mozilla/4.0 (compatible; MSIE 6.0)”. I've just realized that I have exactly the same problem: Be extra careful!...

The Q3 2008 release is now out and I am glad to inform you that RadScriptManager provides support for ASP.NET MVC view and master pages. What this means is that RadControls for ASP.NET Ajax can be used in ASP.NET MVC. We have tested with the ASP.NET MVC Beta 1 release. .csharpcode { overflow:auto; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Using RadControls for ASP.NET Ajax in ASP.NET MVC View Pages 1.

Just before our Q3 release I've made quick test to see how the grid will perform with 1 mil. records table and here is the result: In this example the grid is bound with our new client-side declarative approach to a static page method: ... <DataBinding Location="~/Default.aspx" SelectMethod="GetData" SortParameterType="Linq"  FilterParameterType="Linq" />   ... ... [System.Web.Services.WebMethod]    public static Telerik.Web.UI.GridBindingData GetData(int startRowIndex, int maximumRows, string sortExpression, string filterExpression)    { ...

I've already blogged about the new RadInputManager control in the Beta of Q3 2008 for RadControls ASP.NET AJAX. One of the other very useful features that you can now take advantage of in the RadInputManager is its RegExpTextBox setting. Regular expressions are a good way to validate text fields such as names, addresses, phone numbers, and other user information. You can use it to constrain input, apply formatting rules, and check lengths. If you capture input by using TextBox controls, you can use the RegExpTextBoxSetting settings to validate that input - for example to restrict the range of valid characters, to strip...
