Hi yong kong,

I have talked to the team. It seems it is a known issue which appears in certain scenarios with popup windows.

The good news is that there are workarounds.
Can you please paste me the code where you open the child window on row click , and I will prepare a small sample app with the workaround for you.

Kind regards,

i meet the same problem, the gridview SelectionMode set to Extend.
it's seems handle Grid view  MouseLeftButtonDown event

Mouse.AddMouseDownHandler(this.GridView, new EventHandler<Telerik.Windows.Input.MouseButtonEventArgs>(MouseEventArgsHanderl), true);

void MouseEventArgsHanderl(object sender, Telerik.Windows.Input.MouseButtonEventArgs e)
        {
           // pop a childwindow here.
        }

then you select/click any row,  then close the popup window, move mouse over the gridview, it is will highlight multiple rows.

1.User MVVM to bind Grid

2.PagedCollectionView object on ViewModel.

3.PagedCollectionView.CurrentChangingEventHandler popup childWindow

Hello yong kong,

Ok here is a small hack that should do the trick for you .

Before opening the popup window set

RadGridView.CanUserSelect = false;

and after hiding the window
RadGridView.CanUserSelect = bool;
