[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] }) ...

    How To: Server sorting, filtering, grouping and paging with RadGridView for Silverlight without WCF RIA services

    With our upcoming service pack (Q3 SP2) of RadGridView for Silverlight all operation like sorting, grouping and paging on the server can be achieved completely codeless when the grid is bound to DomainDataSource and in my previous post I’ve showed how to do the same for filtering with minimum code. You can even force the grid vertical scrollbar to page on the server instead DataPager. Since WCF RIA services is still in beta I’ve made small example how to achieve sorting, grouping, paging and filtering using custom web service: XAML <UserControl x:Class="SilverlightApplication1.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"> ...

    How To: Populate RadGridView for Silverlight distinct filters asynchronously using WCF RIA Services

    With our upcoming service pack (Q3 2009 SP2) you will be able to populate distinct values asynchronously using the DistinctValuesLoading event. To achieve this you can assign any INotifyCollectionChanged collection for distinct values ItemsSource and RadGridView will update the UI immediately on any change. I’ve made small demo on how to achieve this using WCF RIA Services and RadGridView bound to DomainDataSource with DataPager – in this case the grid distinct values are populated from the entire collection server-side not only from the current downloaded page:   server-side: public List<DistinctValue> GetDistinctValues(string propertyName) { var list...
