UniPanel.UniGrid has ContextMenu disabled (disabling works when rows present) - Blank Rows still pops up ContextMenu - How to prevent ?

[andyhill]

When Grid shows no rows the user can still invoke ContextMenu, if Grid contains row(s) then my current coding below disables ContextMenu.

How do we prevent Grid ContextMenu with zero rows ? Please advise - thanks

function beforecontainercontextmenu(sender, e, eOpts)
{                     
    e.preventDefault();
}

My apologies Sherzod for using the wrong parameters  I trust the others are correct.

No problem, so, were you able to achieve success?

[andyhill]

Yes - Thank you
