Value Converter In GridViewDataColumn in RadTreeListView colums

[Manishkumar]

Hi,
I am having an issue in binding a Value Converter in a GridViewDataColumn in RadTreeListView columns. If i add the same to DataTemplate then it works fine. Is there any way to directly use with the GridViewDataColumn .

Please find the code below.

This does not work.

<

 

telerik:RadTreeListView x:Name="rtlvPeopleInfo" >

 

 

 

 

    <telerik:RadTreeListView.Columns>

 

 

 

        <telerik:GridViewDataColumn x:Name="gvcPlanFinish" DataMemberBinding="{Binding PlanEndDate}" Header="Plan Finish"

 

 

                Background="{Binding PlanEndDate, Converter={StaticResource PlanFinishBackColorConverterKey}}" 
                DataFormatString="{}{0:MM-dd-yyyy}" />

 

 

 

 

    </telerik:RadTreeListView.Columns>

 

 

 

</telerik:RadTreeListView>

But if i am doing the same in code behind with data template that works fine

 

private

 

void SetValueConvertersInColumns()

 

{

 

GridViewDataColumn gvcPlanFinish = new GridViewDataColumn();

 

 

FrameworkElementFactory tbPlanWork = new FrameworkElementFactory(typeof(TextBlock));

 

 

Binding bndText = new Binding("PlanEndDate");

 

bndText.Mode =

BindingMode.TwoWay;

 

tbPlanWork.SetBinding(

TextBlock.TextProperty, bndText);

 

 

Binding bndPlanWorkBackGround = new Binding("PlanEndDate");

 

bndPlanWorkBackGround.Converter =

this.FindResource("PlanFinishBackColorConverterKey") as IValueConverter;

 

tbPlanWork.SetBinding(

TextBlock.BackgroundProperty, bndPlanWorkBackGround);

 

 

 

DataTemplate dataTemplate = new DataTemplate();

 

dataTemplate.VisualTree = tbPlanWork;

gvcPlanFinish.CellTemplate = dataTemplate;

gvcPlanFinish.CellTemplate.Seal();

gvcPlanFinish.DataMemberBinding =

new Binding("PlanEndDate");

 

rtlvTreeListView.Columns.Add(gvcPlanFinish); //Adding the new column

}

Hi Manishkumar,

You should not set the background of the whole column as you need the color set at cell level.
If you need this done in XAML , you can do it by defining the same cell template in XAML .

As a side note, it seems you are trying to implement conditional cell formatting . the recommended way of doing this is to use a CellStyleSelector.

Thank you so much. I could find my mistake and could successfully develop my requirement.
