I want to create a number of grids that are bound to objects that have Boolean properties.

I want create a generic style that I can apply to various columns of my choosing that causes a cell to have "tick" if the value is true, but a "cross" if the value is false.

    
              <Style x:Key="YesNoCellStyle" TargetType="telerik:GridViewCell"> 
        
                            <Setter Property="Template"> 
        
                                <Setter.Value> 
        
                                    <ControlTemplate TargetType="telerik:GridViewCell"> 
        
                                        <Image x:Name="img" Source="Images/tick.png" 
        
                                                Width="16" Height="16" /> 
        
                                        <ControlTemplate.Triggers> 
        
                                            <DataTrigger Binding="{Binding}" Value="False"> 
        
                                                <Setter TargetName="img" Property="Source" Value="Images/cross.png"/> 
        
                                            </DataTrigger> 
        
                                        </ControlTemplate.Triggers> 
        
                                    </ControlTemplate> 
        
                                </Setter.Value> 
        
                            </Setter> 
        
                        </Style>

So far I have not been able to accomplish this because the DataContext for the GridViewCell is an entire DataRecord, rather than just the field that I'm binding to that column.

Therefore my DataTrigger requires that I know the FieldName or the FieldPosition in order to retrieve the value; so I have to create a template for each DataObject. E.g.

    
            <DataTrigger Binding="{Binding Path=Data.Type}" Value="False"> 
        
            <DataTrigger Binding="{Binding Path=Data.IsAvailable}" Value="False"> 
        
            <DataTrigger Binding="{Binding Path=Data.IsValid}" Value="False">

What I really want is for the Binding to be boudn to whatever value is in the cell being styled. Does anyone know how to acheieve this.

Regards

Justin

Tabbing away from RadDatePicker causes exception in WPF core code

We are currently using a RadDatePicker in an input form and we have discovered a problem with tabbing - when we tab away from the RadDatePicker, we get an exception:

'ContentControl' TargetType does not match type of element 'Control'.

The stack trace shows that the exception is being thrown deep within WPF.

This is very simple to reproduce:

<Window x:Class="RadDatePickerTabBug.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:UI="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Input"
Title="Window1" Height="300" Width="300">
<StackPanel Orientation="Vertical">
<UI:RadDatePicker/>
<TextBox/>
</StackPanel>
</Window>

Running this will reproduce the problem!

Can you help us? The simplicity of reproducing this shows that it's not anything we're doing with styling, retemplating, etc. on the RadDatePicker.

Regards

Chris

RadGridView in a User control

Hi

I am having trouble with the automaic resizing of the radgridview control. If I place it directly inside a grid column row and then set margins to 0 every thing works great and the radgridview fills the area.

If, however, I package the gridview in a usercontrol (within a grid element), and set the margins to 0, the radgridview fills the area as expected. When I then place the resultant usercontrol within a grid cell on a page the usercontrol does not honour the margin 0 properties. The radgridview seems to keep the usercontrol a constant size when manipulating the anchored margins within expression, Visual Studio or manually in the XAML.

I am wondering firstly if this is a bug, secondly if there is a workaround. In your sample application it seems to work fine.

Thanks in advance
Dylan

Style for GridViewHeaderCell in theme is partially ignored

Dear All

We are using a theme to restyle the GridView. We had it looking great in our app before we incorporated the service pack, but now certain things have changed and it looks as if parts of the style for GridViewHeaderCell objects in the header are not being honoured.

In particular, we have this in the ControlTemplate:

<

ContentPresenter Margin="7,4"

HorizontalAlignment="Left"

.../>

-------------
When we use Snoop to look at the resulting visual tree, neither the margin nor the alignment are set to these values. They are "0" and "Center" respectively and their source is given as "ParentTemplate". I had to resort to setting a margin on GridViewHeaderCell to get the previous appearance and I can't find a way of getting Left alignment on the header text.

Is the GridView setting these programmatically? If we had the source for the service pack, we could track this down ourselves.

Thanks for your help

Chris
