Hierarchy child tables

[Yaakov Davis]

It appears that child grid control references are kept in the parent row, even after the row has been collapsed.
Can I make the child grid get disposed?

Hi,

 Indeed the child grid is cached currently and not created on every expand. Here is an example how use RowIsExpandedChanged event to clear this:

private void RadGridView1_RowIsExpandedChanged(object sender, RowEventArgs e)

{

    var row = e.Row as GridViewRow;

    if (row != null && !row.IsExpanded)

    {

        var presenter = e.Row.ChildrenOfType<ContentPresenter>().Where(c => c.Name == "PART_HierarchyChildPresenter").FirstOrDefault();

        if (presenter != null)

        {

            presenter.Content = null;

        }

    }

}
