Simple Theme: Vertical grid lines missing.

Greetings,
I have run into an issue when changing the GridViewRow background color. I have changed the background color based on IsAlternating in the example below: (Note that VerticalGridLinesVisibility is set to True)

    
            <Window.Resources> 
        
                    <Style TargetType="{x:Type telerik:GridViewRow}" > 
        
                        <Style.Triggers> 
        
                            <DataTrigger Binding="{Binding IsAlternating}" Value="False"> 
        
                                <DataTrigger.Setters> 
        
                                    <Setter Property="Background" Value="#ABD5F3" /> 
        
                                </DataTrigger.Setters> 
        
                            </DataTrigger> 
        
                            <DataTrigger Binding="{Binding IsAlternating}" Value="True"> 
        
                                <DataTrigger.Setters> 
        
                                    <Setter Property="Background" Value="#CAEEFE" /> 
        
                                </DataTrigger.Setters> 
        
                            </DataTrigger> 
        
                        </Style.Triggers> 
        
                    </Style> 
        
                </Window.Resources> 
        
                <Grid> 
        
                    <telerik:RadGridView Name="radGridViewStyleSimpleTheme" VerticalGridlinesVisibility="Visible"> 
        
                        <telerik:Theming.Theme> 
        
                            <simple:SimpleTheme /> 
        
                        </telerik:Theming.Theme> 
        
                    </telerik:RadGridView> 
        
                </Grid>

In this example the grid will not show vertical lines with in the rows. I'm guessing this is due to how the controls are layered and the control (Border?) that serves as the row background is overlaying the base grid structure and hiding the grid lines.

I was going to attempt to just change the cell colors themselves based on whether or not they were in an alternating row, however I haven't found a way to accomplish that. I have been unable to find a way to tell if the cell is in an alternating row.

Is there tweak I can make to the control templates to allow grid lines to show in this scenario?

Thanks,
Chris

Custom Styling

Greetings,
I am attempting to do some custom styling based on the Simple theme. I looked over the example provided on this post (http://www.telerik.com/community/forums/thread/b311D-bkeeck.aspx) however it does not work with the latest builds of the WPF gridview control.

Specifically I am having trouble styling the GridViewHeaderRow (or GridViewHeaderCell) and the row selectors (I haven't found the object name for these yet).

The following is a small piece of code from the styling: (Note the dark blue is for testing purposes, end goal is a gradient brush)

    
            <Window x:Class="radGridStyling.Window1" 
        
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                xmlns:radGrid="http://schemas.telerik.com/2008/xaml/presentation" 
        
                xmlns:Simple="clr-namespace:Telerik.Windows.Controls.Simple;assembly=Telerik.Windows.Controls.Simple" 
        
                Title="Window1" Height="401" Width="654" > 
        
                <Window.Resources> 
        
                    <Style TargetType="{x:Type radGrid:GridViewRow}" > 
        
                        <Style.Triggers> 
        
                            <DataTrigger Binding="{Binding IsAlternating}" Value="False"> 
        
                                <DataTrigger.Setters> 
        
                                    <Setter Property="Background" Value="#ABD5F3" /> 
        
                                </DataTrigger.Setters> 
        
                            </DataTrigger> 
        
                            <DataTrigger Binding="{Binding IsAlternating}" Value="True"> 
        
                                <DataTrigger.Setters> 
        
                                    <Setter Property="Background" Value="#CAEEFE" /> 
        
                                </DataTrigger.Setters> 
        
                            </DataTrigger> 
        
                        </Style.Triggers> 
        
                    </Style> 
        
                    <Style TargetType="{x:Type radGrid:GridViewHeaderRow}" > 
        
                        <Setter Property="Background" Value="DarkBlue" /> 
        
                    </Style> 
        
                    <Style TargetType="{x:Type radGrid:GridViewHeaderCell}" > 
        
                        <Setter Property="Background" Value="DarkBlue" /> 
        
                    </Style> 
        
                </Window.Resources> 
        
                <Grid> 
        
                    <radGrid:RadGridView Margin="26,22,79,43" Name="radGridView1" > 
        
                        <radGrid:Theming.Theme> 
        
                            <Simple:SimpleTheme/> 
        
                        </radGrid:Theming.Theme> 
        
                    </radGrid:RadGridView> 
        
                </Grid> 
        
            </Window>

In the example above, the GridViewRow style changes work as expected. However the GridViewHeaderRow and GridViewHeaderCell styles have no impact.

Any guidance would be greatly appreciated!

Thanks,
Chris
