SfTreeGrid is designed to display the self-relational and hierarchical data in tree structure with columns. The data binding can be achieved by assigning the data source to [SfTreeGrid.ItemsSource](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.SfTreeGrid.html#Syncfusion_UI_Xaml_TreeGrid_SfTreeGrid_ItemsSource) property directly through self-relational binding or nested collection or retrieving the parent and child nodes items dynamically using [RequestTreeItems](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.SfTreeGrid.html#Syncfusion_UI_Xaml_TreeGrid_SfTreeGrid_RequestTreeItems) or [LoadOnDemandCommand](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.SfTreeGrid.html#Syncfusion_UI_Xaml_TreeGrid_SfTreeGrid_LoadOnDemandCommand).
