I have a custom control template which is set via the style property on a TextBox. The visual poperties are set correctly, even typing to the textbox works, but there is no insertion cursor (the | symbol) visible which makes editing challenging for our users.
How does the control template need changing to get the traditional TextBox behavior back?
<Style x:Key="DemandEditStyle" TargetType="TextBox">
<EventSetter Event="LostFocus" Handler="DemandLostFocus" />
<Setter Property="HorizontalAlignment" Value="Stretch" />
<Setter Property="VerticalAlignment" Value="Stretch" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="1" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="1" />
</Grid.RowDefinitions>
<Grid.Background>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Color="White" Offset="0" />
<GradientStop Color="White" Offset="0.15" />
<GradientStop Color="#EEE" Offset="1" />
</LinearGradientBrush>
</Grid.Background>
<Border Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2" Background="Black" />
<Border Grid.Row="0" Grid.Column="1" Grid.RowSpan="2" Background="Black" />
<Grid Grid.Row="0" Grid.Column="0" Margin="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="1" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="1" />
<RowDefinition Height="*" />
<RowDefinition Height="1" />
</Grid.RowDefinitions>
<Border Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="3" Background="Black" />
<Border Grid.Row="0" Grid.Column="0" Grid.RowSpan="3" Background="Black" />
<Border Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="3" Background="#CCC" />
<Border Grid.Row="0" Grid.Column="2" Grid.RowSpan="3" Background="#CCC" />
<TextBlock Grid.Row="1" Grid.Column="1"
TextAlignment="Right" HorizontalAlignment="Center" VerticalAlignment="Center"
Padding="3 0 3 0" Background="Yellow"
Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Text}"
Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Grid}, AncestorLevel=1}, Path=ActualWidth}" />
</Grid>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Update: Replacing the inner-most TextBox with a ScrollViewer and naming it PART_ContentHost indeed shows the text insertion cursor.
Trying to right-align the text in the TextBox by either setting the HorizontalContentAlignment in the Style or as a property on the ScrollViewer were unsuccessful.
Suggestions?
