If you are familiar with the RadGridView‘s Custom Filtering Functionality you probably know that you can create any kind of user control to replace the default one which looks like this:

Very often, however, you may be perfectly happy with the stock filtering control, but you wish you could modify and adapt it just a little bit to match your particular requirements. What should you do then? Maybe build an entirely new filtering control from scratch that looks just like RadGridView’s default one and adds this tiny bit of functionality? No, that would be insane. There is an ...

In my previous blog post I have demonstrated how to display master-details data in an asynchronous manner with RadGridView for Silverlight and WCF RIA Services. I have decided to refactor the sample project a little bit and add some very basic editing support. Here is the changes I have made to the sample project:

1. I have recreated the ChinookService to support editing.
2. I have encapsulated the details grid into a new user control called AlbumsControl.
3. I have added a “Submit Changes” button below the details grid.
4. I got rid of the IValueConverter that used to create the albums DomainDataSource ...

Q2 and Q3 releases brought up support for commands usable in a similar way as the commanding mechanism from WPF.

In a few points the Commanding mechanism provides several classes:

• RoutedCommand and RoutedUICommand – ICommand implementations, the second has a Text property
• ICommandSource – once an object implement it, it knows how to invoke a command, i.e. it receives Command, CommandParameter and CommandTarget properties.
• CommandBinding – maps the command logic to the command
• CommandManager – provides methods that register CommandBinding and InputBinding objects, add and remove command event handlers, and provides services for querying the status of a command. ...

Inspired by Brad Abrams’ marvelous series of blog posts, I have decided to create a simple project demonstrating how to harness the enormous power of RIA Services with Telerik RadGridView for Silverlight. I have decided to use the new Chinook database after reading this wonderful post by Tim Heuer explaining how to work with relational data in the RIA Services paradigm. Make sure you have this database installed on the default instance of your SQL Server 2008 Express or you will have to modify the connection string as needed.

In one of my previous blog posts I have ...

Sometimes when using a Docking control and implementing complex UI with it we need to add some custom rules about allowing some panes to be docked in some parts of the application and to disallow them to dock to other parts. As this behavior is quite complex itself, we’ve decided to enable some scenarios to be available in XAML in a declarative way (the more static scenarios) and some scenarios to be available only through the code-behind.
 
In this post I will guide you through some simple steps that will show you how you could use both approaches. First ...

In my previous blog post I explained how to display RadGridView Row Details with a RadWindow. Several days after the post was published I received a suggestion to create another sample that will be showing Row Details in a mouse-over tooltip fashion. And guess what. Christmas came earlier this year.

The full credit for coming up with this brilliant idea goes to my friend and colleague Kalin Milanov, our Front-end Developer. He decided to edit the GridViewRow ControlTemplate and removed the DetailsPresenter from the spot it usually occupies under the cells. He then placed it inside a ToolTip...

In one of my previous blog posts I have explained how to display hierarchical data with Row Details. Now, if you are familiar with Row Details features, you know that you are not limited to showing the details inside RadGridView. You can show them anywhere by using the handy external DetailsPresenter. As a matter of fact, each GridViewRow has one of those DetailsPresenter’s inside its template. So you will be using the same class that we are using internally to show the details of each single row.

The documentation states that in order to display Row ...

As we received a lot of questions on how to add a ScrollViewer to the RadMenu control for Silverlight, in this blog post I am going to explain how you can achieve this.

Adding a ScrollViewer to RadMenu for Silverlight can be easily accomplished using Expression Blend.

Step 1. Create a new Silverlight 3 Application.

Step 2. Add references to Telerik.Windows.Controls.dll and Telerik.Windows.Controls.Navigation.dll in your project.

Step 3. Drag RadMenu and RadMenuItem controls from the Toolbox and drop them on the design surface.

 

Step 4. Right-click on one of the RadMenuItems and select EditStyle or ...

It’s been a while since the Q3 2009 release. Lots of controls have been added in our toolbox for WPF. One of them is considered as a final official release of RadDocking control for WPF. We have made a lot of improvements since the last release of the controls. For example each of the six themes included in the bundle now has different type of appearance when applied to a control. RadDocking is a fully customizable and skinnable control that enhances the power of a layout system. It is providing you with a docking system like the one in Microsoft Visual Studio. You are getting the dockable ToolWindows, ...

If you are familiar with the Row Details feature of RadGridView, you probably have used the VisibleWhenSelected mode in the beginning. In case you have not, you should definitely check out the online example of Row Details.

A couple of months after the Row Details debut, we introduced a new type of column called GridViewToggleRowDetailsColumn, which does exactly what its names says – it provides and easy and fast way of toggling the details visibility of individual rows.

Now, what if you are using this specialized column, but want to achieve a VisibleWhenSelected-like behavior. Let’s see how to ...
