Example

All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.

The following examples demonstrates how to change the edit template of the cell editor for the ShipVia column to a Slider control.

XAML

<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}"/> 

  </Grid.Resources> 

  <xcdg:DataGridControl x:Name="OrdersGrid" 

                        ItemsSource="{Binding Source={StaticResource cvs_orders}}"> 

    <xcdg:DataGridControl.Columns> 

 

     <xcdg:Column FieldName="ShipVia"> 

       <xcdg:Column.CellEditor> 

         <xcdg:CellEditor> 

           <xcdg:CellEditor.EditTemplate> 

             <DataTemplate> 

               <Slider Value="{xcdg:CellEditorBinding}" Minimum="1" Maximum="3"/> 

             </DataTemplate> 

           </xcdg:CellEditor.EditTemplate> 

           <xcdg:CellEditor.ActivationGestures> 

             <xcdg:KeyActivationGesture Key="Right"/> 

             <xcdg:KeyActivationGesture Key="Left"/> 

           </xcdg:CellEditor.ActivationGestures> 

         </xcdg:CellEditor> 

       </xcdg:Column.CellEditor> 

     </xcdg:Column> 

    </xcdg:DataGridControl.Columns> 

  </xcdg:DataGridControl> 

</Grid>

The following example demonstrates how to change the edit template of the cell editor for the Freight column to a custom calculator control. The C# code for the Calculate method called in the buttons' Click event simply calculates the new equation and is not provided. To shorten the code, some of the Button and KeyActivationGesture declarations have been removed.

XAML

<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}"/> 

  </Grid.Resources> 

   <xcdg:DataGridControl x:Name="OrdersGrid" 

                         ItemsSource="{Binding Source={StaticResource cvs_orders}}"> 

      <xcdg:DataGridControl.Columns> 

 

        <xcdg:Column FieldName="Freight"> 

           <xcdg:Column.CellEditor> 

              <xcdg:CellEditor> 

                 <xcdg:CellEditor.EditTemplate> 

                    <DataTemplate> 

                        <DockPanel> 

                           <TextBlock x:Name="actual_value" 

                                     Text="{xcdg:CellEditorBinding}" 

                                      DockPanel.Dock="Top"/> 

                           <UniformGrid Columns="4" x:Name="parentPanel" 

                                        Tag="{Binding ElementName=actual_value, 

                                                      Path=Text, 

                                                      Mode=TwoWay, 

                                                      UpdateSourceTrigger=PropertyChanged}" 

                                        Button.Click="Calculate" 

                                        DockPanel.Dock="Top"> 

                              <Button x:Name="seven" Content="7"/> 

                              <!-- ... --> 

                              <Button x:Name="addition" Content="+"/> 

                           </UniformGrid> 

                           <TextBlock x:Name="current_equation" DockPanel.Dock="Bottom"/> 

                         </DockPanel> 

                     </DataTemplate> 

                 </xcdg:CellEditor.EditTemplate> 

                 <xcdg:CellEditor.ActivationGestures> 

                    <xcdg:KeyActivationGesture Key="NumPad0"/> 

                    <!-- ... --> 

                    <xcdg:KeyActivationGesture Key="NumPad9"/> 

                 </xcdg:CellEditor.ActivationGestures> 

              </xcdg:CellEditor> 

           </xcdg:Column.CellEditor> 

        </xcdg:Column> 

      </xcdg:DataGridControl.Columns> 

   </xcdg:DataGridControl> 

</Grid>

The following example demonstrates how to provide a default cell editor for columns that have an Int32 data type.

XAML

<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid" 

      xmlns:s="clr-namespace:System;assembly=mscorlib"> 

  <Grid.Resources> 

    <xcdg:DataGridCollectionViewSource x:Key="cvs_orders" 

                                    Source="{Binding Source={x:Static Application.Current}, 

                                                      Path=Orders}"/> 

  </Grid.Resources> 

  <xcdg:DataGridControl x:Name="OrdersGrid" 

                        ItemsSource="{Binding Source={StaticResource cvs_orders}}"> 

 

   <xcdg:DataGridControl.DefaultCellEditors> 

     <xcdg:CellEditor x:Key="{x:Type s:Int32}"> 

       <xcdg:CellEditor.EditTemplate> 

         <DataTemplate> 

           <Slider Value="{xcdg:CellEditorBinding}"/> 

         </DataTemplate> 

       </xcdg:CellEditor.EditTemplate> 

     </xcdg:CellEditor> 

   </xcdg:DataGridControl.DefaultCellEditors> 

  </xcdg:DataGridControl> 

</Grid>
