Pressed VisualState for GridViewHeaderCell

[Sergey]

Hello!
I try to customize style for GridViewHeaderCell. I created template for it and it works fine. But I'm surprized that it have no "Pressed" visual state. I want to change background of header of GridView when it pressed. Any ideas how I can do it?

Hi Sergey,

Actually, the pressed state of GridViewHeaderCell is the selected one. So, you may try to edit the "_Selected" elements of its template. Please take a look at our online documentation for a reference.

Selected state doesn't works.
Can you share sample where it works for you?

Hello Sergey,

I am sending you a sample project illustrating how you may change the background of a GridViewHeaderCell when it is selected. You mainly need to edit the following part:

<Border x:Name="GridViewHeaderCell_Selected" BorderBrush="{StaticResource GridView_HeaderOuterBorder_Selected}" BorderThickness="{TemplateBinding BorderThickness}" Grid.ColumnSpan="2" Opacity="0">
                    <Border BorderBrush="{StaticResource GridView_HeaderInnerBorder_Selected}" BorderThickness="1" Background="{StaticResource GridView_HeaderBackground_Selected}"/>
                </Border>

 

Kind regards,

I have the same question Maya. Is there a way to change a header background color only when the mouse is in the down position (pressed position)? I am looking for something similar to what is described in this article: http://msdn.microsoft.com/en-us/library/ms742286(v=vs.85).aspx, but for a silverlight project.

Thanks,

Karan

Hi Karan,

Such behavior in Silverlight will require more code and customization that in WPF. You need to create your own custom state (for pressed position of the header), handle MouseLeftButtonDown event, call GoToState method of VisualStateManager to invoke the state you want. However, you will need to handle MouseLeftButtonUp event and return the state of the header to is default one when it is clicked - sorted in descending, ascending or none state.
