Binding to the DataView of a DataTable

This article will demonstrate how to bind a RadGridView to the DataView of a DataTable. An important thing when using a DataTable as a data source for a RadGridView is to make sure that the ItemsSource property of the control is bound to the DefaultView property of the DataTable, which is of type DataView.

Binding to DataTable's DefaultView

Example 1 demonstrates how you can set up a ViewModel containing a DataTable in order to bind it to the RadGridView.

Example 1: Setting up the ViewModel

public class MyViewModel : ViewModelBase 
    private DataTable datatable; 
    public DataTable DataTable 
            if (this.datatable == null) 
                this.datatable = this.CreateDataTable(); 
            return this.datatable; 
    private DataTable CreateDataTable() 
        var dataTable = new DataTable(); 
        dataTable.Columns.Add(new System.Data.DataColumn("FirstName", typeof(string))); 
        dataTable.Columns.Add(new System.Data.DataColumn("LastName", typeof(string))); 
        dataTable.Columns.Add(new System.Data.DataColumn("City", typeof(string))); 
        for (int i = 1; i <= 50; i++) 
            var row = dataTable.NewRow(); 
            row["FirstName"] = "FirstName " + i; 
            row["LastName"] = "LastName" + i; 
            row["City"] = "City " + i; 
        return dataTable; 
Public Class MyViewModel 
    Inherits ViewModelBase 
        Private _datatable As DataTable 
        Public ReadOnly Property DataTable() As DataTable 
                If Me._datatable Is Nothing Then 
                    Me._datatable = Me.CreateDataTable() 
                End If 
                Return Me._datatable 
            End Get 
        End Property 
        Private Function CreateDataTable() As DataTable 
            Dim _datatable = New DataTable() 
            _datatable.Columns.Add(New System.Data.DataColumn("FirstName", GetType(String))) 
            _datatable.Columns.Add(New System.Data.DataColumn("LastName", GetType(String))) 
            _datatable.Columns.Add(New System.Data.DataColumn("City", GetType(String))) 
            For i As Integer = 1 To 50 
                Dim row = _datatable.NewRow() 
                row("FirstName") = "FirstName " & i 
                row("LastName") = "LastName" & i 
                row("City") = "City " & i 
            Next i 
            Return _datatable 
        End Function 
End Class 

Example 2 demonstrates how the RadGridView is set up in XAML. Please, pay attention to the fact that the ItemsSource is bound to the DefaultView property of the DataTable.

Example 2: Setting up the RadGridView

        <!-- The namespace "my" refers to the namespace where the MyViewModel class is defined--> 
        <my:MyViewModel /> 
    <telerik:RadGridView ItemsSource="{Binding DataTable.DefaultView}" 
            <telerik:GridViewDataColumn DataMemberBinding="{Binding FirstName}"/> 
            <telerik:GridViewDataColumn DataMemberBinding="{Binding LastName}"/> 
            <telerik:GridViewDataColumn DataMemberBinding="{Binding City}" />
