How to cell HeaderCellStyle for Columns of a grid with AutoGenerateColumns=true?

[Abhay]

Hello,

I have a grid with AutogenerateColumns=true and all it's columns are generated dynamically. I want to set HeaderCellStyle property for it's columns. Please suggest a solution.

Thanks,

Hello,

You can define the style as an implicit one, thus applying it for all the columns. If you want to set it only to some particular ones, you can handle AutoGeneratingColumn event and assign the style defined in xaml to the HeaderCellStyle of the column.

Hello Pascal,

You can define an implicit style that will be applied to all header cells:

<UserControl.Resources>
   <Style TargetType="telerik:GridViewHeaderCell">
       <Setter Property="Background" Value="SpringGreen" />
   </Style>
</UserControl.Resources>

The other possible approach would be to set it explicitly during AutoGeneratingColumn:

//XAML:
 <UserControl.Resources>
        <Style x:Key="MyHeaderCellStyle" TargetType="telerik:GridViewHeaderCell">
            <Setter Property="Background" Value="SpringGreen" />
        </Style>
    </UserControl.Resources>

//C#:
    private void clubsGrid_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)
        {
            e.Column.HeaderCellStyle = (Style)this.Resources["MyHeaderCellStyle"];
        }
