Hello Manishkumar,

You can try to define a simple style targeting GridViewToggleButton and set its PresentationMode property to "PlusMinus".

I defined the style in Resource.
<Style x:Key="PlusMinusButtonStyle" TargetType="telerik:GridViewToggleButton">

 

 

 

<Setter Property="PresentationMode" Value="PlusMinus" />

 

 

 

</Style>

 

I implemented the style in TreeListView.

 

HierarchyExpandButtonStyle = "{StaticResource PlusMinusButtonStyle}"

Still it is not working. Can u please help me
