I have a textbox withing a template that is not updating. I have forced update thru code behind, but that is far from ideal. Here is the template:

<Style x:Key="CellPresenterButtonTextbox"
 TargetType="{x:Type igDP:CellValuePresenter}"
 BasedOn="{StaticResource {x:Type igDP:CellValuePresenter}}">
<Style.Resources>
</Style.Resources>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">
<Grid>
<Button Name="AggregationButton"
HorizontalAlignment="Stretch"
Margin="2,.5"
Padding="4,0"
Height="20"
Command="{Binding DataContext.DataItem.CommandInterface, RelativeSource={RelativeSource Self}}"
CommandParameter="Aggregate"
Visibility="Hidden">
<TextBlock Text="Aggregate"
 FontWeight="Black"
 FontSize="10" />
</Button>
<TextBox Name="BasketTextBox"
 HorizontalAlignment="Stretch"
 VerticalAlignment="Stretch"
 Background="#FF222222"
 Foreground="White"
 Margin="2,.5"
 Text="{TemplateBinding Content}"
 LostFocus="UpdateStrategy"
 Visibility="Hidden" />
</Grid>
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding DataContext.DataItem.Type, RelativeSource={RelativeSource Self}}"
 Value="Aggregation">
<Setter Property="Visibility"
TargetName="BasketTextBox"
Value="Visible" />
</DataTrigger>
<DataTrigger Binding="{Binding DataContext.DataItem.Type, RelativeSource={RelativeSource Self}}"
 Value="Basket">
<Setter Property="Visibility"
TargetName="AggregationButton"
Value="Visible" />
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Here is the Field:

 <igDP:Field Name="Strategy"
Label="Strategy"
Width="72">
<igDP:Field.Settings>
<igDP:FieldSettings CellValuePresenterStyle="{StaticResource CellPresenterButtonTextbox}"
CellClickAction="EnterEditModeIfAllowed"
AllowEdit="True" />
</igDP:Field.Settings>
</igDP:Field>

As I said have it working with code behind, but not a good situation.
