[Solved] Group height

[Voss Grose]

Is it possible to set the height of a GroupHeader?

[Kalin Milanov]

Hello Voss Grose,

There is a way to adjust the height of the group header though it will require editing the template of the group row. Attached I am sending you a sample application which does just that.

I hope you will find it useful.

Thanks for the zip, but I was pretty overwhelmed by the zip file you sent.

Is all of that code necessary to alter the height of a group header?

This is my group header template xaml code (from the direction of previous Telerik assistance):

            <telerik:RadGridView.GroupHeaderTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Header, Converter={StaticResource TimeConverter}}" Loaded="Group_Loaded" Width="375" Height="12" FontSize="10">
                        <telerikNavigation:RadContextMenu.ContextMenu>
                            <telerikNavigation:RadContextMenu EventName="MouseRightButtonDown">
                                <telerikNavigation:RadContextMenu.Items>
                                    <telerikNavigation:RadMenuItem Header="Block Time Slots" Click="OnMenuItemClick" Tag="Block" />
                                    <telerikNavigation:RadMenuItem Header="Un-Block Time Slots" Click="OnMenuItemClick" Tag="Un-Block" />
                                    <telerikNavigation:RadMenuItem Header="Add Time Slot" Click="OnMenuItemClick" Tag="Add" />
                                </telerikNavigation:RadContextMenu.Items>
                            </telerikNavigation:RadContextMenu>
                        </telerikNavigation:RadContextMenu.ContextMenu>
                    </TextBlock>
                </DataTemplate>
            </telerik:RadGridView.GroupHeaderTemplate>
            <telerik:RadGridView.GroupDescriptors>
                <data:GroupDescriptor Member="Time">
                    <!--
                    <data:GroupDescriptor.AggregateFunctions>
                        <data:CountFunction Caption="COUNT: " />
                    </data:GroupDescriptor.AggregateFunctions>
                    -->
                </data:GroupDescriptor>
            </telerik:RadGridView.GroupDescriptors>

Hi Voss Grose,

 I realize the amount of XAML needed to change the value of a simple property is rather big. The problem lies in the template of the group row (which is missing a proper Height binding) and thus setting the height only in GroupRowStyle results are less than satisfactory. That being said we are going to be implementing a fix which will reduce the amount of XAML needed to just 3 lines.

Until then the proposed solution is the best way of meeting your requirements.

Best wishes,
