Question

When running a getSelectionModel().clearSelections() on a grid that uses a Ext.selection.CheckboxModel and all rows was selected using the “select all” check box at the top of the select column, the “select all” check box remains checked.

I did a dirty hack to get around this but I wish to know if there is a cleaner way or if this is a bug.

Answer 1

I’d try to put a listener on a grid component to track selection changes (not sure if it will help):

listeners: {
   selectionchange: function(grid, selected) {
        if(!selected.length) {
            grid.getSelectionModel().deselectAll();
        }
   }
}

Btw, have you tried to do getSelectionModel().deselectAll()? clearSelections is deprecated in ExtJS 4.1 and it’s runned on view not selection model.
