Last week Telerik released the Data Service Wizard Beta 1. It will automatically create for you the end points for an Astoria, WCF, or RESTful service. New in the beta of the Data Service Wizard is the ability of the wizard to automatically generate the DataServiceKey attribute required to make relationships in Astoria work. When you use "Astoria" (ADO.NET||WCF) Data Services, by default Astoria tries to map the primary keys in your entities using a convention. This is important for your service to work. The mapping works out of the box for the Entity Framework, however, if you are using LINQ to SQL or Telerik Open Access, it does not since some...

  A client has recently asked for these little fancy math toolbars in the column header. I found it a great idea and thought it might be useful to share the way of implementing this with RadGridView for Silverlight.   *Since RadGridView for WPF shares the same code base  the approach bellow may be used for both platforms ( Silverlight and WPF ) .   Things are easy with RadGridView !   To have this in your project follow these three easy steps :   1. Copy the MathToolBar user control from the attached sample project (MathToolBar.xaml, MathToolBar.cs). MathToolbarDemo.zip 2. Replace the default header in the column with the user control. <telerik:GridViewDataColumn ... <telerik:GridViewDataColumn.Header> <local:MathToolBar HeaderText="Value1"/> </telerik:GridViewDataColumn.Header> </telerik:GridViewDataColumn>   3. Adjust...

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 easier way to do this....

Did you know that you can serialize any DataTable to Silverlight easily from your custom WCF service in very few lines of code? [OperationContract] public IEnumerable<Dictionary<string, object>> GetData() { var table = YourDataTable; var columns = table.Columns.Cast<DataColumn>(); return table.AsEnumerable().Select(r => columns.Select(c => new { Column = c.ColumnName, Value = r[c] }) ...
