In order to make a grid with TreeView selection mode, we need to set the IsTreeViewSelectionMode to true. Please check sample code belows:

C# Copy Code 
WebGrid1.RootTable.SelfReferencingSettings.Enabled = true;
WebGrid1.RootTable.SelfReferencingSettings.ParentDataMember = "FolderID";
WebGrid1.RootTable.SelfReferencingSettings.ChildDataMember = "ParentFolderID";
WebGrid1.RootTable.SelfReferencingSettings.ExpandColumnMember = "Name";
WebGrid1.RootTable.SelfReferencingSettings.IsTreeViewSelectionMode=True;
WebGrid1.RootTable.SelfReferencingSettings.ParentRootMode =
    ISNet.WebUI.WebGrid.ParentRootMode.UseParentRootValue;


This is the result of the TreeView mode sample using SelfReference feature of WebGrid :
