Bug with focus at DataGrid

[iseeyou]

I have DataGrid? and ToolTipDialog?, for setup visibility of columns, on my page. So, when i click to DataGrid?, header was get focus, and when i open dropdown menu with my ToolTipDialog? and changing visibility of column (checkbox), then tooltip was closed. I found with debugger, that when header has focus, focus always changing to grid.domNode in function _delayedHeaderFocus, becouse even if focus was removed from DataGrid?, header of grid stay focused. This condition checked in function isNavHeader. So, i changed isNavHeader to (i added checking to if current focused node is descendant of grid.domNode)

isNavHeader: function(){ 
                // summary: 
                //	states whether currently navigating among column headers. 
                // returns: 
                //	true if focus is on a column header; false otherwise. 
                return (!!this._colHeadNode && (!dijit._curFocus || dojo.isDescendant(dijit._curFocus,this.grid.domNode))); 
        },

DojoX Grid and EnhancedGrid are deprecated in favor of ​dgrid and ​gridx.

You should upgrade your code to use one of those two grids.

We will consider patches to the old DojoX Grid code though.
