Hi Priya,

Hello Priya,

I am just checking if you require any further assistance on the matter.

Hello Priya,

Thank you for your reply. I have been looking into it and I believe that the style for the ‘ExpansionIndicator’ is not applied in your application since in Krasimir’s application everything is applied as expected. I tested your style on my side and it is applied as expected, too. I am attaching a sample application(xamDataGrid-ExpandIndicator.zip) that shows that.

It seems that you are missing something in your application.

Let me know, if you need any further assistance on this matter.

Hello Yanko,

I added below code:

<Grid.Resources>
--><!--<local:MarginConverter x:Key="MarginConverter"/>
<Style TargetType="{x:Type igDP:DataRecordPresenter}" BasedOn="{x:Null}">
<Setter Property="Margin" Value="{Binding RelativeSource={RelativeSource Self}, Path=DataRecord.NestingDepth, Converter={StaticResource MarginConverter}}"/>
</Style>--><!--
<Style TargetType="{x:Type igWindows:ExpansionIndicator}">
<Setter Property="Background">
<Setter.Value>
<LinearGradientBrush EndPoint="1,1" StartPoint="0,0">
<GradientStop Color="sc#1, 0.57900393, 0.57900393, 0.57900393" Offset="1"/>
<GradientStop Color="Wheat" Offset="0.36153846153846259"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
<Setter Property="BorderBrush" Value="#FF999999"/>
<Setter Property="Foreground" Value="Black"/>
<Setter Property="Cursor" Value="Hand"/>
<Setter Property="ClipToBounds" Value="False"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type igWindows:ExpansionIndicator}">
<Grid Background="Transparent">
<Grid x:Name="grdExpansionIndicatorClosed" Height="9" RenderTransformOrigin="0.5,0.5" SnapsToDevicePixels="True" Width="9">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
</Grid.RowDefinitions>
<Border x:Name="outerBorder" Background="{TemplateBinding BorderBrush}" CornerRadius="2" RenderTransformOrigin="0.5,0.5"/>
<Border x:Name="innerFill" Background="{TemplateBinding Background}" CornerRadius="1.5" Height="Auto" Margin="1" RenderTransformOrigin="0.5,0.5" Width="Auto"/>
<Rectangle x:Name="plusHorizontal" Fill="{TemplateBinding Foreground}" HorizontalAlignment="Stretch" Height="1" Margin="2,4" RenderTransformOrigin="0.5,0.5" VerticalAlignment="Stretch" Width="Auto"/>
<Rectangle x:Name="plusVert" Fill="{TemplateBinding Foreground}" Height="Auto" Margin="4,2" RenderTransformOrigin="0.5,0.5" Width="1"/>
</Grid>
</Grid>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsChecked" Value="True"/>
</MultiTrigger.Conditions>
<Setter Property="Visibility" TargetName="plusVert" Value="Collapsed"/>
</MultiTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Grid.Resources>

It still does not indent expansion indicators. Is there anything else I am supposed to do.

Surprisingly solution provided by Krasimir works as expected. But in my code it does not get reflected. 

The only difference is the datasource we are binding. I am binding nested collection to my Xamdatagrid. Is there something I am missing?

Thanks,

Priya
