WPF Toolkit: how to scroll datagrid to show selected item from code behind?

Question

I tried following, all of following fails on function ScrollIntoView and gives NullReferenceException.

// doesnt work
grid.SelectedItem = sItem;
grid.ScrollIntoView(sItem);

// doesnt work
grid.SelectedItem = sItem;
grid.Focus();
grid.CurrentColumn = grid.Columns[0];
grid.UpdateLayout();
grid.ScrollIntoView(sItem,grid.Columns[0]);

// doesnt work
grid.SelectedItem = sItem;
grid.UpdateLayout();
grid.ScrollIntoView(sItem);

The problem is, when I select row from codebehind, selection is not visible its somewhere down in bottom, unless user scrolls he feels that selection has vanished. I need to scroll datagrid to the point user can see the selection.

I also tried "BringIntoView" as well but no luck.

Answer 1

Try:

grid.SelectedItem = sItem; 
grid.UpdateLayout();
grid.ScrollIntoView(grid.SelectedItem);

Answer 2

Virtualized Stack Panel didnt have item container, because Item Container does not exist for the item outside the view and thats why this error was shown. Disabling virtualization resolves issue for now, and the bug has been reported to codeplex toolkit project.
