    [CLOSED] Unable to deselect selected rows in gridpanel if all rows selected and drag and drop enabled

    1. Select All Rows using shift click
    2. Note that there is now no way to unselect selected rows

    Normal behavior is that clicking on a selected row will unselect all other rows. However, this doesn't work if EnableDragDrop="true" for the grid. While I understand that if you click a row without releasing the mouse, you should be able to keep current selected rows and drag. However, if you click and release the mouse, it should unselect all other rows. I dont see a RowKeyUp listener in the grid or in the selectionmodel.

    This happen more often than you think where our users select all the rows in a grid and are "stuck". They are not super tech savy so they dont know that ctrl+click will unselect that row. They are used to other applications where selection will be reset if you click a row.
