[Solved] Changing Header Cell Color

[Keith Stephens]

Hello all,

I have searched for this, but could not find a simple exapmle of what I am trying to do.

I have a gridview and I need to change the header color of just some of the header cells. Some need to be blue and some red.

Also some of the datacolumn use the header property and some use.  Also I do not have expression blend so that is no help to me right now.

<telerikGridView:GridViewDataColumn.Header>
                                            <StackPanel Orientation="Vertical">
                                                <TextBlock Text="Cost" HorizontalAlignment="Center" />
                                                <TextBlock Text="Rate" HorizontalAlignment="Center" />
                                            </StackPanel>
                                        </telerikGridView:GridViewDataColumn.Header>

Thanks,
KS

Hi Keith Stephens,

You can easily achieve this result without using Blend  if you define a HeaderCellStyle for your columns as you can see in the following code snippet:

<telerik:GridViewDataColumn  DataMemberBinding="{Binding Property1}">
  <telerik:GridViewDataColumn.Header>
       <StackPanel Orientation="Vertical">
       <TextBlock Text="Cost" HorizontalAlignment="Center"/>
          <TextBlock Text="Rate" HorizontalAlignment="Center"/>
       </StackPanel>
  </telerik:GridViewDataColumn.Header>
  <telerik:GridViewDataColumn.HeaderCellStyle>
   <Style TargetType="telerik:GridViewHeaderCell">
       <Setter Property="Background" Value="Red"/>
      <Setter Property="Foreground" Value="Black"/>
     <Setter Property="FontSize" Value="20"/>
    </Style>
</telerik:GridViewDataColumn.HeaderCellStyle>
</telerik:GridViewDataColumn>

is there a way to use color codes?

D7E4BC - greenish color
FFFFCC - yellowish color

Also could you explain to me what the difference is in the following 2 assemblies?
In order for me to see the HeaderCellStyle I had to add the xmlns:telerikGridView1 name space.

xmlns:telerikGridView="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
xmlns:telerikGridView1="clr-namespace:Telerik.Windows.Controls.GridView;assembly=Telerik.Windows.Controls.GridView"

Thanks,
KS

Hi Keith Stephens,

Yes you can use the hexadecimal representation of the colours,please refer to the following:

<Setter Property="Background" Value="#FFD7E4BC"/>

To answer to your the second question there are some differences between these namespaces,beause there are elements that are missing in the first namespace,but they are available for use in the second namespace.
Please let me know if you need any further assistance.

All the best,
