Grouping data in the RadGridView for WPF
When you first add the RadGridView to your WPF application you will undoubtedly notice the section at the top of the control which I have outlined in red. This area is officially called the GridViewGroupPanel, but I am just going to call it the Group Panel to save myself some typing. The Group Panel allows the user to drag and drop column headers into the panel in order to group the data in the RadGridView at runtime. Below you will see that I have grouped my data by the "Make" column in my grid of vehicles. Additionally, the sort order of...May 27, 2021 3 min read -

Reporting: How to set default value for a multivalue parameter
Generally when you want to set a default value for a parameter, you use the Value property of the parameter (this.ReportParameters["MyParam"].Value), but what to set when you want all values to be selected by default i.e you have a multivalue parameter? You can do that by providing an ArrayList containing all your values to the report parameter Value property. For consistency of the Tips & Tricks series, I am going to use the project from the Using Report parameters UI to sort by column blog post. Let's make the SortByColumn parameter accept multivalues by setting the MultiValue property to True. We... -

RadControls for WinForms and Windows 7 beta
A couple of days ago I finally managed to get my hands on the latest hype, Windows 7, and to give it a spin. The first impression I got after installing the new OS went to the performance improvements it offered – it felt better than Vista, and the boot up time was really impressive. Then came the appreciation of the UI improvements which seem to be a natural evolution of the features Vista introduced. Win7 goodies aside, I am happy to say that RadControls for WinForms run perfectly fine on the beta – there are no hiccups, messed layouts... -

RadComboBox and ASP.NET AJAX 4.0 Preview – using client-side templates and webservice load on demand
Edit: The following content applies to ASP.NET Ajax 4.0 Preview 4. Download the project that uses the latest MS Ajax 4.0 Preview 6 from Here Many of you have asked us, the ASP.NET support officers, whether RadComboBox supports templates when bound to WebService. Using the latest official .NET Framework (3.5) the answer was ‘no’. Fortunately, this is possible with the client-side templates introduced in the next version of the .NET Framework – 4.0. Currently it is in a Preview stage and you can find its roadmap here. We have already demonstrated how to use the new client-side templates in RadTreeView and RadGrid. -

Encode and Decode strings using JavaScript
In order for a string to be read from all computers sometimes it is useful to encode and decode it. This can be easily achieved using the JavaScript built-in escape() and unescape() methods. Both the escape() and the unescape() methods have the same argument – the string which will be escaped or unescaped. The escape() method returns a string value (in Unicode format) that represents the encoded contents of the function argument. All spaces, punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding, where xx is equivalent to the hexadecimal number representing the character. For example, a space is returned as "%20". Additionally, having... -
