="{Binding Path=DisplayContent}" doesn't get any value

[Elena]

Hi,
Jag have an existing Custom Theme for RadGridView which is not entire correct because in
<ControlTemplate x:Key="GridViewGroupPanelItemTemplate" TargetType="grid:GridViewGroupPanelItem">
Content="{Binding Path=DisplayContent}" doesn't get any value. I think it something is missing in our GridViewTheme.xaml. Would be very grateful for any tip.
Best regards
Elena


<ControlTemplate x:Key="GridViewGroupPanelItemTemplate" TargetType

Hello Elena,

Thank you for this feedback. I have reproduced the behavior that you experience. You may fix this by using "Column.Header" instead of DisplayContent. They are returning one and the same value.

<telerik:GridViewGroupPanelCell Content="{Binding Column.Header}"  />

We are going to investigate further what would be causing this strange behavior with the binding to the DisplayContent.  Greetings,

Thank you sa much!
 I will test your advice tomorrow because of DataBase problem. After Windows updatings SQL Server doesn't start and I can't debug/start my project :(. 
Yours truly.

Hy,

I've got the same problem...

This isn't work:

<telerik:GridViewGroupPanelCell Content="{Binding Column.Header}"  />

<telerik:GridViewGroupPanelCell
                Content="{Binding Path=DisplayContent}"
                Style="{StaticResource GridViewGroupPanelCellStyle}"
                SortDirection="{Binding Path=SortDirection}" />

 To:

<telerik:GridViewGroupPanelCell
                Content="{TemplateBinding Content}"
                Style="{StaticResource GridViewGroupPanelCellStyle}"
                SortDirection="{Binding Path=SortDirection}" />

Would be very grateful for any tip, too :-)

Thanks

Olli

Hi,

Have you tried the following:

<telerik:GridViewGroupPanelCell
     Content="{TemplateBinding Content.Header}"
     Style="{StaticResource GridViewGroupPanelCellStyle}"
     SortDirection="{Binding Path=SortDirection}" />

Regards,

Hy Didie,

yes, but isn't works too...

Do you have a any idea?

<telerik:GridViewGroupPanelCell
     Content="{TemplateBinding Content.Header}"
     Style="{StaticResource GridViewGroupPanelCellStyle}"
     SortDirection="{Binding Path=SortDirection}" />

--> In VS 2010 comes this error:

Type 'Content' was not found. 

Thanks

Hi,

It was long time ago. Try this. It works for me.

              <grid:GridViewGroupPanelCell

                                                              Background="Transparent"

                                                              BorderThickness="0"

                                                              Content="{Binding Column.Header}"

                                                              Foreground="#204d89"

                                                              Padding="12,0,12,2"

                                                              SortDirection="{Binding Path=SortDirection}"/>

Hy,

@Elena
            It was long time ago
yeah  :-)


This will works for me:

<grid:GridViewGroupPanelCell
        FontSize="{StaticResource FontSizeGridViewHeaderGroup}"
        Foreground="{StaticResource BaseForeground}"
        Content="{Binding Column.Header}"
        Padding="12,3,12,2" Height="24"
        SortDirection="{Binding Path=SortDirection}"
        Style="{StaticResource GridViewGroupPanelCellStyle}" />

The problem was my style definition (GridViewGroupPanelCellStyle), this was corrupt...


Thanks all for support...

Best Regards
Olli
