How To

Create DataTemplates and then apply them as grid cell editors.

Solution

To achieve this, follow these steps:

1. Specify the DataGrid's namespace.

xmlns:c="clr-namespace:VIBlend.Silverlight.Controls;assembly=VIBlend.Silverlight.DataGrid"

2. Create Data Templates which represent a TextBox and CheckBox editors.

<UserControl.Resources>
    <!-- DataTemplate for TextBox in-place editor -->
    <DataTemplate x:Key="cellEditTextBoxTemplate">
        <TextBox Text="{Binding BookTitle, Mode=TwoWay}"/>
    </DataTemplate>

    <!-- DataTemplate for CheckBox in-place editor -->
    <DataTemplate x:Key="cellEditCheckBoxTemplate">
        <Grid>
            <editors:CheckBox IsChecked="{Binding IsInStock, Mode=TwoWay}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
        </Grid>
    </DataTemplate>

    <!-- DataTemplate for CheckBox column -->
    <DataTemplate x:Key="cellCheckBoxTemplate">
        <Grid>
            <editors:CheckBox IsChecked="{Binding IsInStock}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
        </Grid>
    </DataTemplate>
</UserControl.Resources>

3. Create a new DataGrid instance and add its BoundFields. Set the CellEditTemplate property to point to the cellEditTextBoxTemplate.

<viblend:DataGrid x:Name="dataGrid" Margin="4" Grid.Row="1" AutoGenerateColumns="True">
<c:DataGrid.BoundFields>
    <c:BoundField Text="Book Title" DataField="BookTitle" Width="145" CellEditTemplate="{StaticResource cellEditTextBoxTemplate}" CellEditorActivationFlags="MOUSE_CLICK_SELECTED_CELL" CellEditorDeActivationFlags="MOUSE_CLICK" />
    <c:BoundField Text="ISBN" DataField="ISBN" Width="165"/>
    <c:BoundField Text="Author" DataField="Author" Width="155" SortMode="Automatic" />
    <c:BoundField Text="In Stock" DataField="IsInStock" Width="147" SortMode="Automatic" CellEditorActivationFlags="MOUSE_MOVE" CellEditorDeActivationFlags="MOUSE_MOVE" CellDataTemplate="{StaticResource cellCheckBoxTemplate}" CellEditTemplate="{StaticResource cellEditCheckBoxTemplate}"/>
</c:DataGrid.BoundFields>
