Do not filter on null
This post might seem like a no brainer, but I've received quite a few inquiries on this matter recently, so decided to post here. Let's say you have a parameter of Type: DateTime with AllowNull: true and we filter on a field based on the input parameter value i.e.: Expression Operator Value =========== ======== ================================= =Fields.MyField = =Parameters.MyParam When we tick the 'null' checkbox, it basically filters the report to find the Fields with Nulls. However one might expect that it just won't filter at all with this setup. And indeed if you do not wish to filter, you should not have to. Then how do you handle "empty/blank" values in such cases and... -
Web ASP.NET AJAX

It's alive. Before anything else, it's a preview, so it may burn you. You've been warned! Colorization Surprise, surprise! I hope you didn't see that one coming.

Saving some lines of code when using RadWindow
If you are using some of the predefined modal dialogs part of RadWindow: Alert, Prompt and Confirm you may find this article quite handy. As you know the calls to these methods are asynchronous, thus you cannot stop the current UI thread in order to get the user feedback from the windows synchronously. This introduces some issues such as the need to declare class member variables whenever they may not be necessary. Due to that there have been a few requests on our support website to create a generic parameter inside the static calls of the dialogs with the purpose of carrying... -

Integrating RadChart for Silverlight in existing ASP.NET applications
There’s an emerging trend to integrate cool new silverlight controls into existing production asp.net solutions. And why wouldn’t it be there? There are many asp.net applications in production out there that have been working quite well and don’t need to be replaced by a completely new technology. Wouldn’t it be nice, however, to spice them up a little with some rich silverlight visualization tools? This is exactly what a lot of our customers have been asking for lately. Well, here you can see some resources we published that will help anyone who wants to plug in RadChart for Silverlight in... -

Applying Themes on RadControls for Silverlight
The theme engine of RadControls for Silverlight is quite powerful and provides the developers with the ability to apply application-wide theme on all RadControls, as well as specific theme on a single control. If the theme does not contain the needed styles, the controls fallback to their default styles, so you could create an application theme for just a couple of controls and the rest will display with their default styles. We also provide styles for the standard controls, such as Button, CheckBox, RadioButton, etc. which enables you to create application with consistent look and feel. Each theme is distributed as...May 27, 2021 5 min read -

GridView in ComboBox with RadControls for Silverlight
Recently we received several requests for an example, demonstrating how to put a virtualized GridView in a ComboBox popup. The best way to do this in my opinion is to replace the ItemsPresenter of the ComboBox with a GridView. There is some plumbing that has to be done, but I managed to separate it in two attached behaviors. The original idea is described in my blog post for TreeView in ComboBox which I recently updated with the latest control template of RadComboBox for Silverlight. The principle is exactly the same with RadGridView and it should work with very minor adjustments with...May 27, 2021 3 min read -
