NuGet Package: DevExpress.Wpf.Grid.Core
If you lock the GridControl, a user cannot change data within the control. You can accumulate changes and update data in one action. As a result, you can improve the performance of the GridControl during data shaping operations. Call the DataControlBase.BeginDataUpdate method to lock updates.
An EndDataUpdate() method call should follow every DataControlBase.BeginDataUpdate call.
The TreeListView saves the current state of all nodes (selected or expanded) when you call the DataControlBase.BeginDataUpdate method and restores this state when you call EndDataUpdate(). If properties bound to the state are changed during data updates (see IsCheckBoxEnabledBinding and ExpandStateBinding), you can save the changed state. To do that, call the TreeListView.SaveNodesState method before EndDataUpdate().
