I have some strange problems with the GroupByArea in the xamDataGrid. First I tried to change the colors in the GroupByArea with following commands in the xamDataGrid.Resources
<LinearGradientBrush x:Key="{ComponentResourceKey {x:Type igDP:XamDataGrid}, GroupByBackground}" StartPoint="0,0" EndPoint="0,1" PresentationOptions:Freeze="true"> <GradientStop Color="DarkSeaGreen" Offset="0"/> <GradientStop Offset="1"> <GradientStop.Color> <Color A="255" R="35" G="69" B="36"/> </GradientStop.Color> </GradientStop></LinearGradientBrush>
or
<SolidColorBrush x:Key="{x:Static igDP:DataPresenterBrushKeys.GroupByBackgroundKey}" Color="Red" />
Nothing happened, even with other GroupByArea-Keys.
So I settled for using the grey GroupByArea in the Onyx Theme, but then the next problems occured. When I set Theme to Onyx in XAML, the GroupByArea is displayed in the default blue, only when I set Theme to Onyx in the C# - Code Behind with
ThemeManager.SetTheme(xamDataGrid1, "Onyx");
the GroupByArea is displayed in grey. Next problem is, when I try to change its prompts, because they need to be in German language
<Window.Resources> <Style x:Key="grpStyle" TargetType="{x:Type igDP:GroupByArea}"> <Setter Property="Prompt1" Value="Gruppieren"/> <Setter Property="Prompt2" Value="Hierher ziehen"/> </Style> </Window.Resources>
<igDP:XamDataGrid DockPanel.Dock="Top" Name="xamDataGrid1" Width="Auto" Height="Auto" BorderThickness="2" GroupByAreaStyle="{StaticResource grpStyle}">
the prompts are changed, but the GroupByArea is blue again.
I have no idea to deal these problems, please tell me, what i´ve done wrong.

Hello Frank,
Customizing the GroupByArea is an easy task to accomplish -- there is a great example in the XamFeatureBrowser in the XamDataGrid - Themes and Custom Styles - Custom GroupByArea Style. The default styles of all the controls parts you can find in the local directory on your computer:
"~\Infragistics\NetAdvantage for WPF 2008 Vol. 2\DefaultStyles" where you can get the base style and build your own.
Here is a simpel style:
<Style x:Key="MyCustomGroupByArea" TargetType="{x:Type igDP:GroupByArea}"> <Setter Property="FontSize" Value="12"/> <Setter Property="Foreground" Value="#FFFFFF"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type igDP:GroupByArea}"> <ControlTemplate.Resources> <Storyboard x:Key="TurnOnInsertionPoint"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="PART_InsertionPoint" Storyboard.TargetProperty="(UIElement.Opacity)"> <SplineDoubleKeyFrame KeyTime="00:00:00.2500000" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <Storyboard x:Key="TurnOffInsertionPoint"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="PART_InsertionPoint" Storyboard.TargetProperty="(UIElement.Opacity)"> <SplineDoubleKeyFrame KeyTime="00:00:00.2500000" Value="0"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </ControlTemplate.Resources> <Grid x:Name="outerGrid" d:LayoutOverrides="Height"> <Rectangle Opacity="1" Stroke="#FFBAB7B7" StrokeThickness="0" Width="Auto" Height="Auto" Margin="0,0,0,0"> <Rectangle.Fill> <LinearGradientBrush EndPoint="0.575,0.986" StartPoint="0.575,-0.017"> <GradientStop Color="#4C30245C" Offset="0"/> <GradientStop Color="#FFFFFFFF" Offset="1"/> </LinearGradientBrush> </Rectangle.Fill> </Rectangle> <StackPanel Orientation="Horizontal" Margin="6,12,0,0"> <TextBlock x:Name="prompt1" FontSize="24" Text="Grupieren" Opacity=".5" /> <TextBlock x:Name="prompt2" Opacity=".8" Margin="5,11.2,0,0" Text="Hierher ziehen" /> </StackPanel> <!-- GroupedFieldLabelsArea--> <Grid x:Name="PART_GroupedFieldLabelsArea" Margin="0,12,0,0" VerticalAlignment="Top" d:IsLocked="True"> <!-- GroupedFields List --> <igDP:GroupByAreaFieldListBox x:Name="GroupedFieldList" ItemsSource="{TemplateBinding GroupedFieldLabels}"/> </Grid> <!-- End GroupedFieldLabels Area --> <!-- AvailableFieldLabels Area --> <Grid x:Name="PART_AvailableFieldLabelsArea" Margin="0,49,0,15" Visibility="Visible" d:IsLocked="True"> <!-- AvailableField List --> <igDP:GroupByAreaFieldListBox ItemsSource="{TemplateBinding AvailableFieldLabels}"/> </Grid> <!-- End AvailableFieldLabels Area --> <!-- Insertion Point --> <Polygon x:Name="PART_InsertionPoint" Opacity="0" Fill="#FF151C55" Points="0,0 10,0 5,5" StrokeEndLineCap="Round" StrokeStartLineCap="Round" StrokeLineJoin="Round" HorizontalAlignment="Left" Margin="0,12,0,0" VerticalAlignment="Top"/> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsExpanded" Value="True"/> <EventTrigger RoutedEvent="igDP:GroupByArea.ShowInsertionPoint"> <EventTrigger.Actions> <BeginStoryboard x:Name="TurnOnInsertionPoint_BeginStoryboard" Storyboard="{StaticResource TurnOnInsertionPoint}"/> </EventTrigger.Actions> </EventTrigger> <EventTrigger RoutedEvent="igDP:GroupByArea.HideInsertionPoint"> <EventTrigger.Actions> <BeginStoryboard x:Name="TurnOffInsertionPoint_BeginStoryboard" Storyboard="{StaticResource TurnOffInsertionPoint}"/> </EventTrigger.Actions> </EventTrigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style>
<igDP:XamDataGrid Theme="Onyx" Name="xamDataGrid1" GroupByAreaStyle="{StaticResource MyCustomGroupByArea}" >
Concerning the theme, I set the theme through xaml and code bihind and it is working just fine as you can see in the screenshot. I do not know where the problem might be.
Hope this helps.
Alex, Great job on the grouping design! In your snippet is there a way to set this style to open collapsed rather than expanded as does this example?
Thanks,
Glenn
Alex,
Thanks for the update looking good!
Viel Spass
Glenn,
This time I am going to propose a more "civilized" way of doing this with Customization Strings
Infragistics.Windows.DataPresenter.Resources.Customizer.SetCustomizedString("GroupByArea_Prompt1", "New Custom Prompt 1");
Infragistics.Windows.DataPresenter.Resources.Customizer.SetCustomizedString("GroupByArea_Prompt2", "New Custom Prompt 2");
I am also attaching a file with the default GroupByArea style, which you can also find in the DefaultStyles directory.
