    Silverlight/WPF : Custom Legend with RadChart

      One of the less known features supported by Telerik’s RadChart for Silverlight/WPF is the ability to completely abandon the default control layout and build one of your own with no constraints for the number of elements used. The goal of this blog post is to shed some light on this functionality and to demonstrate the most common techniques that can be used to customize the legend. First of all, to build your own custom chart layout you should set the UseDefaultLayout property of the RadChart object to false. Here is the custom layout I prepared: <telerik:RadChart x:Name="RadChart1" UseDefaultLayout="False">             <Grid>                 <Grid.ColumnDefinitions>                     <ColumnDefinition Width="50"/>                     <ColumnDefinition Width="*"/>                 </Grid.ColumnDefinitions>                 <Grid.RowDefinitions>                     <RowDefinition Height="*"/>                    ...

    Telerik RadMap for Silverlight – OpenStreetMap provider

    RadMap_OpenStreetMap.zip I am glad to announce that with the release of RadControls for Silverlight Q3 2009 Service Pack 1 RadMap has been updated to support OpenStreetMap provider. It is as easy as setting a single property: MyRadMap.Provider = new OpenStreetMapProvider();   Set the Center and Location properties and you are ready to go. Here is an example of RadMap with our Boston office address in the center: <map:RadMap x:Name="RadMap1" ZoomLevel="13">     <map:RadMap.Provider>         <mapNamespace:OpenStreetMapProvider />     </map:RadMap.Provider>     <map:RadMap.Center>             <mapNamespace:Location Latitude="42.397223" Longitude="-71.254685" />      </map:RadMap.Center> </map:RadMap>    And this is the result   You can find a link to a sample project in the beginning of this blog...

    How To: Tooltip Row Details with RadGridView for Silverlight

    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: 1: <ToolTipService.ToolTip> 2: <ToolTip Style="{StaticResource ToolTipStyle}" ...

    How To: Display RadGridView Row Details with RadWindow for Silverlight

    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 Details outside RadGridView, you need to place...
