I have telerik:RadGridView  control, I want to set text 's color of header for Grid, I tried some ways as implement behind code, set property in XAML file, but I can't set color for text of Grid's header. (I'm using the latest ver of SilverLight 4.0 )
- case of XAML file:

 <Grid Grid.Row="3" Grid.Column="1" Margin="15,15,15,12" Grid.RowSpan="2">
                            <Grid.Resources>
                                <Style x:Key="GridViewHeaderRowStyle" TargetType="telerik:GridViewHeaderRow">
                                    <Setter Property="Template" Value="{StaticResource GridViewHeaderRowTemplate}"/>
                                    <Setter Property="Background" Value="#CC0010"/>
                                    <Setter Property="Foreground" Value="White"/>
                                   
                                </Style>
                            </Grid.Resources>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="0.041*"/>
                                <ColumnDefinition Width="0.145*"/>

                                ShowGroupPanel="False"  Grid.ColumnSpan="3"   telerikGridViewFilter:CustomFilterRow.IsEnabled="True"
                                                                         >

                        </Button.RenderTransform>
                    </Button>
                </Grid>
            </telerik:RadBusyIndicator>
        </Grid>
- Case of code hehind:

 this.grdRDFMatrix.DataLoaded += new System.EventHandler<System.EventArgs>(grdRDFMatrix_DataLoaded);
 private void grdRDFMatrix_DataLoaded(object sender, System.EventArgs e)
        {
            foreach (var col in this.grdRDFMatrix.Columns)
            {
                col.HeaderCellStyle = (Style) this.Resources["GridViewHeaderRowStyle"];
            }
        }

More: I changed successfully with background property but impossible with Foreground.
It's better, if you have simple example about change text 's color of header Grid using Foreground property.

Hello Totti,

You can try to set a style targeting the GridViewHeaderCell:

Is there a way to control a grid header foreground and background individually? Meaning not change all the column headers to the same color or same text? i'm using GridViewTextBoxColumn in WinForms version 2012.2.912.40

Hi Claudio,

Will it be possible to post your question on the related WinForms telerik forum ?
Thank you in advance.
