Hello anandbabu,

Here is a modification of the jqxGrid demo Context Menu. In the example, the menu opens according to the window bounds (note that only the rowclick binding has been changed):

This works great, except if you have a sub menu. The sub-menu still draws off the page/screen. Is there any way to force the sub-menu to draw up?
You can see here how it draws it off the screen.

Never mind 🙂
Found this in a sample and it works like a champ.

$("#taskGridContextMenu").jqxMenu('setItemOpenDirection', 'LinkTasks', 'right', 'up');
