[Solved] Header-styles for group and filler-column

[Rudolf Bösch]

Hi there

I'm trying to customize the styles in a RadGridView. Basically, using cutomized HeaderCellStyle and RadGridViewStyle works fine, but how to apply such customisations for the filler-cloumn header and the groups header ?
(see attached screenshot, the custom color is the gray gradient)

Thanks in advance for your help!

Cheers

Hi Rudolf Bösch,

What you are looking for is the style for the GridViewHeaderRow. You can apply a style to it using HeaderRowStyle property of the RadGridView.

Let me know if you encounter any difficulties in this task.

Hi Kalin Milanov,

thanks for your help! However, this does not seem to work. I create a style, kinda like

Style oStyle = new Style(typeof(GridViewHeaderRow));
oStyle.Setters.Add(new Setter(GridViewHeaderRow.BackgroundProperty, _headerColor));
oStyle.Setters.Add(new Setter(GridViewHeaderRow.BorderBrushProperty, _headerColor));

and then assining it to the grid:

RadGrid.HeaderRowStyle = oStyle;

the result is that the header does not change its style at all (remains all blue gradient).
Anyways, the same procedure with the HeaderCellStyle for each column of the grid works fine, it just does not consider the grouping and the filler columns.

It would be great if you could tell me how the whole header row can be styled the same :o)

cheers

Hello Rudolf Bösch,

I would suggest you do all your styling in XAML. Here is how the header row style might look like.

    <UserControl.Resources>
        <Style x:Key="GridViewHeaderRowStyle" TargetType="Telerik_Windows_Controls_GridView:GridViewHeaderRow">
            <Setter Property="Background" Value="Red"/>
            <Setter Property="MinHeight" Value="26"/>
            <Setter Property="BorderBrush" Value="Blue"/>
            <Setter Property="BorderThickness" Value="0,0,0,1"/>
        </Style>
    </UserControl.Resources>

    <Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding Source={StaticResource SampleDataSource}}">
        <telerikGridView:RadGridView Margin="0" ItemsSource="{Binding Collection}" HeaderRowStyle="{StaticResource GridViewHeaderRowStyle}" />
    </Grid>

I hope this helps.

Kind regards,

Hi Kalin Milanov,

basically this is no solution inmy project, the styles are applied after getting the users credentials and assigned depending on them. This works for all of the other components I use.

But never mind, I'll find a solution somehow.

Thanks for your help anyways.
