  1. POHow to select all the text when the edit textbox in a DataGridTemplateColumn receives focus?
    text
    copied!<p>I'm trying to get a DataGridTemplateColumn to behave identically to a TextColumn </p> <ul> <li>when the cell goes into edit mode (Press F2), the user can immediately start typing in the new value</li> <li>by default, existing text content is selected - so that you can set new values easily</li> </ul> <p>Got the first one done ; however selecting all the text isn't working. As mentioned by a number of posts, tried hooking into the GotFocus event and selecting all the text in code-behind. This worked for a standalone textbox ; however for a Textbox which is the edit control for a TemplateColumn, this doesn't work.</p> <p>Any ideas? Code Sample:</p> <pre><code>&lt;Window.Resources&gt; &lt;Style x:Key="HighlightTextBoxStyle" TargetType="{x:Type TextBox}"&gt; &lt;EventSetter Event="GotFocus" Handler="SelectAllText"/&gt; &lt;EventSetter Event="GotMouseCapture" Handler="SelectAllText"/&gt; &lt;Setter Property="Background" Value="AliceBlue"/&gt; &lt;/Style&gt; &lt;DataTemplate x:Key="DefaultTitleTemplate"&gt; &lt;TextBlock Text="{Binding Title}"/&gt; &lt;/DataTemplate&gt; &lt;DataTemplate x:Key="EditTitleTemplate"&gt; &lt;TextBox x:Name="Fox" FocusManager.FocusedElement="{Binding RelativeSource={RelativeSource Self}}" Text="{Binding Path=Title, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Style="{StaticResource HighlightTextBoxStyle}"&gt; &lt;/TextBox&gt; &lt;/DataTemplate&gt; &lt;/Window.Resources&gt; &lt;DockPanel&gt; &lt;TextBox DockPanel.Dock="Top" x:Name="Test" Text="{Binding Path=(FocusManager.FocusedElement).Name, ElementName=MyWindow}" Style="{StaticResource HighlightTextBoxStyle}"/&gt; &lt;toolkit:DataGrid ItemsSource="{Binding Items}" AutoGenerateColumns="False"&gt; &lt;toolkit:DataGrid.Columns&gt; &lt;toolkit:DataGridTemplateColumn Header="Templated Title" CellTemplate="{StaticResource DefaultTitleTemplate}" CellEditingTemplate="{StaticResource EditTitleTemplate}" /&gt; &lt;toolkit:DataGridTextColumn Header="Title" Binding="{Binding Path=Title}" /&gt; &lt;/toolkit:DataGrid.Columns&gt; &lt;/toolkit:DataGrid&gt; &lt;/DockPanel&gt; </code></pre>

An individual column

Larger individual text columns get their own page to allow for proper reading.
