Filtering data items (Filter Event)
The following example demonstrates how to filter the data items displayed in a grid using the Filter event. Only the data items whose ShipVia property value is "3" will be displayed in the grid.
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">
<Grid.Resources>
<xcdg:DataGridCollectionViewSource x:Key="cvs_orders"
Source="{Binding Source={x:Static Application.Current},
Path=Orders}"
Filter="ShipViaFilter"/>
</Grid.Resources>
<xcdg:DataGridControl x:Name="OrdersGrid"
ItemsSource="{Binding Source={StaticResource cvs_orders}}"/>
</Grid> | The following code provides the implementation of the ShipViaFilter event. This code should be placed in the "code-behind" of your XAML page.
VB.NET
Private Sub ShipViaFilter( sender As Object, e As FilterEventArgs )
Dim value As Object = CType( e.Item, System.Data.DataRow )( "ShipVia" )
If( Not value Is Nothing ) And ( Not value Is DBNull.Value ) Then
If CInt( value ) = 3 Then
e.Accepted = True
Else
e.Accepted = False
End If
End If
End Sub
C#
private void ShipViaFilter( object sender, FilterEventArgs e )
{
object value = ( ( System.Data.DataRow )e.Item )[ "ShipVia" ];
if( ( value != null ) && ( value != DBNull.Value ) )
{
if( ( int )value == 3 )
{
e.Accepted = true;
}
else
{
e.Accepted = false;
}
}
