How to allow selection of just one row

Hi, when I enable selection on a GridTree control, I can highlight multiple rows.  Disabling selection prevents this but then of course you don't get the necessary data in SelectionChange events.

How can you prevent selection of multiple rows in the GridTree please?

Hi Craig, 
Thanks for contacting Syncfusion support. 
We have analyzed your query and you can achieve your requirement using ListBoxSelectionMode property in GridTreeControl. Using this property, you can change the SelectionMode in GridTreeControl. 
Please refer the below code example. 
     this.treeGrid.EnableNodeSelection = true;               this.treeGrid.Model.Options.AllowSelection = GridSelectionFlags.Row; 
            this.treeGrid.Model.Options.ListBoxSelectionMode = GridSelectionMode.One;     
Please download sample from the below location. 
Sample Location: WPF
