    I'm trying to figure out how to collapse the visible rows, and then to expand them again. Is there a straightforward way to do that?

    I'm able to get the correct visual behavior by removing the items from the RadGridView (Collapse) and adding them back (Expand). Is there a better way?

    For clarification, here are screenshots of what I'm after:

    Expanded state: (see radgridview_expanded.png)

    Collapsed state: (see radgridview_collapsed.png)

    Thank you,

    Hi Jon,

    You may try to change the ItemsSource of the grid from a filled-in one and an empty one. Thus on clicking each of the buttons, the grid will either be with all its items or with none. You can take a look at this blog post for a reference on similar scenario.
