+This sample illustrates how to change the checkbox column values based on selection in [WPF TreeGrid](https://www.syncfusion.com/wpf-controls/treegrid) (SfTreeGrid).
 
-In `TreeGrid`, you can select multiple rows using the [SelectionMode](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Grid.SfGridBase.html#Syncfusion_UI_Xaml_Grid_SfGridBase_SelectionMode) property. You can process the CheckBoxSelection using [TreeGridCheckBoxColumn](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.TreeGridCheckBoxColumn.html) and a boolean property called `IsSelected` in Model. You can also select all the rows in `TreeGrid` by defining the CheckBox in header cell of `GridCheckBoxColumn` using [GridColumn.HeaderTemplate](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.SfTreeGrid.html#Syncfusion_UI_Xaml_TreeGrid_SfTreeGrid_HeaderTemplate).
