I am looking for a way to set a gradientbrush as the background for a listbox item. I have a DataTemplate defined and have specified a gradient brush but it always appears as the listbox background (i.e. it never shows as a gradient brush).

I have been able to set the background of the listbox itself, and I can set the listboxitem's background to a standard color using the "setter" object....but none of these are what I am after.

I really want the background on each list item to be a gradient brush.

Below is the datatemplate that I have constructed.

<ListBox Name="MyListBox"  Margin="12,67,12,169">

        <ListBox.ItemTemplate>
        <DataTemplate>
                <Grid Height="51"  VerticalAlignment="Bottom">
                    <Grid.Background>
                        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                            <GradientStop Color="#FFC9F4D0"/>
                            <GradientStop Color="#FF2AC12A" Offset="0.333"/>
                            <GradientStop Color="#FF35DE35" Offset="1"/>
                        </LinearGradientBrush>
                    </Grid.Background>
                    <Canvas >
                        <dataInput:Label Width="227" Foreground="Yellow" Canvas.Left="158" Canvas.Top="8" Content="{Binding Place}"/>
                        <dataInput:Label Width="146" Foreground="Yellow" Canvas.Left="8" Canvas.Top="8" Content="{Binding Date}"/>
                        <dataInput:Label Content="{Binding People}" Width="346" FontSize="9.333" Foreground="Black" Canvas.Left="166" Canvas.Top="28"/>
                        <!-- <dataInput:Label Width="45" Content="Accept" Foreground="White" Canvas.Left="8" Canvas.Top="28"/>
                        <dataInput:Label Width="45" Content="Decline" Foreground="White" Canvas.Left="57" Canvas.Top="28"/> -->
                        <dataInput:Label Content="SomeText" Width="101" FontSize="9.333" Foreground="White" Canvas.Left="389" Canvas.Top="10"/>
                        <Image Height="21" Width="21" Canvas.Left="500" Canvas.Top="8" Source="Green Button.png"/>
                    </Canvas>
                </Grid>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

Any Thoughts?
