How to modified text 's color of header

[Totti]

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*"/>
                                <ColumnDefinition Width="0.814*"/>
                            </Grid.ColumnDefinitions>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="*"/>
                                <RowDefinition Height="auto"/>
                                <RowDefinition Height="30"/>
                            </Grid.RowDefinitions>
                            <telerik:RadGridView Grid.Row="0" AutoGenerateColumns="False" Name="grdRDFMatrix"
                                ColumnWidth="*" GridLinesVisibility="Horizontal"
                                ScrollViewer.VerticalScrollBarVisibility="Auto"                                
                                IsReadOnly="True" ItemsSource="{Binding DataList, Mode=TwoWay}"                                      
                                CanUserInsertRows="True"  
                                          
                                ShowGroupPanel="False"  Grid.ColumnSpan="3"   telerikGridViewFilter:CustomFilterRow.IsEnabled="True"
                                                                         >
                                <telerik:RadGridView.Columns>
                                    <telerik:GridViewDataColumn Header="Rate" UniqueName="Rate" Width="*"  HeaderCellStyle="{StaticResource GridViewHeaderRowStyle}" />
                                    <telerik:GridViewDataColumn Header="Destination" UniqueName="Destination" Width="*" HeaderCellStyle="{StaticResource GridViewHeaderRowStyle}"/>
                                    <telerik:GridViewDataColumn Header="Format" UniqueName="Format" Width="*" HeaderCellStyle="{StaticResource GridViewHeaderRowStyle}" />
                                    <telerik:GridViewDataColumn Header="Fee Table" UniqueName="FeeTable" Width="*" HeaderCellStyle="{StaticResource GridViewHeaderRowStyle}"/>
                                </telerik:RadGridView.Columns>
                            </telerik:RadGridView>
                            <telerik:RadDataPager Grid.Row="1" Template="{StaticResource RadDataPagerTemplate}"
                                   x:Name="radDataPager1"
                                   PageSize="{Binding Value, ElementName=Pagesize,Mode=TwoWay}"
                                   Source="{Binding Items, ElementName=grdRDFMatrix}"
                                   DisplayMode="All"
                                   AutoEllipsisMode="Both"

                                   IsTotalItemCountFixed="True"  Grid.ColumnSpan="3" />
                            <StackPanel Orientation="Horizontal" Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="2" Width="200">

                                    <ColumnDefinition Width="*"/>
                                    <ColumnDefinition Width="*"/>
                                </Grid.ColumnDefinitions>
                                <Button Grid.Column="0" Content="Save" Width="66" Height="25" VerticalAlignment="Center" Command="{Binding SaveRDFCommand}" CommandParameter="InsertRDFMatrix" HorizontalAlignment="Left"/>
                                <Button Content="Associate" Height="25" Grid.Column="1" HorizontalAlignment="Center" Width="83" VerticalAlignment="Center" Click="btnAssociate_Click"/>
                                <StackPanel Grid.Column="2" Orientation="Horizontal" HorizontalAlignment="Right" Margin="0,0,5,0">
                                    <HyperlinkButton Content="Import" Grid.Column="1" FontSize="12"  Name="lnkImport" VerticalAlignment="Center" Grid.Row="2" />
                                    <TextBlock Grid.Column="1"  Text="/" VerticalAlignment="Center" FontSize="12" Margin="5,0,5,0"/>
                                    <HyperlinkButton Content="Export" Grid.Column="1"  Name="lnkExport" FontSize="12" VerticalAlignment="Center"/>
                                </StackPanel>
                            </Grid>
                        </Grid>
                    </Border>

                    <Button Click="btnNextFT_Click" x:Name="BtBottomRight" Content="" Grid.Column="1" Grid.Row="4" HorizontalAlignment="Right" VerticalAlignment="Center"  Style="{StaticResource ArrowButton}"  Width="28" Grid.ColumnSpan="2" Margin="0,130,97,80">
                        <Button.RenderTransform>
                            <CompositeTransform Rotation="90"></CompositeTransform>
                        </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:

<Style TargetType="telerik:GridViewHeaderCell">
    <Setter Property="Foreground" Value="HotPink"/>
    <Setter Property="Background" Value="Azure" />
</Style>

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.
