How to set alternate row background in MultiColumn TreeViewAdv?
This article describes how to set alternate row background for multiple column TreeViewAdv control.
AlternationCount and AlternationIndex
Use AlternationCount and AlternationIndex properties to specify the appearance for alternating item containers.
The following code example demonstrates the same.
XAML
<syncfusion:TreeViewAdv AlternationCount="2" MultiColumnEnable="True">
<syncfusion:TreeViewAdv.Resources>
<Style TargetType="syncfusion:TreeViewItemAdv">
<Style.Triggers>
<Trigger Property="AlternationIndex" Value="0">
<Setter Property="Background" Value="LightBlue" />
</Trigger>
<Trigger Property="AlternationIndex" Value="1">
<Setter Property="Background" Value="LightGray" />
</Trigger>
</Style.Triggers>
</Style>
</syncfusion:TreeViewAdv.Resources>
<syncfusion:TreeViewItemAdv>
<syncfusion:TreeViewItemAdv.Header>
<local:TreeModel TreeHeader ="Item 1" Description="Description about Item 1"/>
</syncfusion:TreeViewItemAdv.Header>
</syncfusion:TreeViewItemAdv>
<syncfusion:TreeViewItemAdv>
<syncfusion:TreeViewItemAdv.Header>
<local:TreeModel TreeHeader ="Item 2" Description="Description about Item 2"/>
</syncfusion:TreeViewItemAdv.Header>
</syncfusion:TreeViewItemAdv>
