andyhill Posted March 24 Share Posted March 24 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 ////////////////////////////////////////////////////////////////////////////// // Before Container MyScript:= 'beforecontainercontextmenu=function beforecontainercontextmenu(sender, td, cellIndex, record, tr, rowIndex, e, eOpts) '#13#10 + '{ '#13#10 + ' e.preventDefault(); '#13#10 + '} '; grdWorkSheet.ClientEvents.ExtEvents.Add(MyScript); // Container MyScript:= 'containercontextmenu=function containercontextmenu(sender, td, cellIndex, record, tr, rowIndex, e, eOpts) '#13#10 + '{ '#13#10 + ' e.preventDefault(); '#13#10 + '} '; grdWorkSheet.ClientEvents.ExtEvents.Add(MyScript); // Row MyScript:= 'rowcontextmenu=function rowcontextmenu(sender, td, cellIndex, record, tr, rowIndex, e, eOpts) '#13#10 + '{ '#13#10 + ' e.preventDefault(); '#13#10 + '} '; grdWorkSheet.ClientEvents.ExtEvents.Add(MyScript); // Before Cell MyScript:= 'beforecellcontextmenu=function beforecellcontextmenu(sender, td, cellIndex, record, tr, rowIndex, e, eOpts) '#13#10 + '{ '#13#10 + ' e.preventDefault(); '#13#10 + '} '; grdWorkSheet.ClientEvents.ExtEvents.Add(MyScript); // Cell MyScript:= 'cellcontextmenu=function cellcontextmenu(sender, td, cellIndex, record, tr, rowIndex, e, eOpts) '#13#10 + '{ '#13#10 + ' e.preventDefault(); '#13#10 + '} '; grdWorkSheet.ClientEvents.ExtEvents.Add(MyScript); // Before Item MyScript:= 'beforeitemcontextmenu=function beforeitemcontextmenu(sender, td, cellIndex, record, tr, rowIndex, e, eOpts) '#13#10 + '{ '#13#10 + ' e.preventDefault(); '#13#10 + '} '; grdWorkSheet.ClientEvents.ExtEvents.Add(MyScript); // Item MyScript:= 'itemcontextmenu=function itemcontextmenu(sender, td, cellIndex, record, tr, rowIndex, e, eOpts) '#13#10 + '{ '#13#10 + ' e.preventDefault(); '#13#10 + '} '; grdWorkSheet.ClientEvents.ExtEvents.Add(MyScript); // Header MyScript:= 'headercontextmenu=function headercontextmenu(sender, td, cellIndex, record, tr, rowIndex, e, eOpts) '#13#10 + '{ '#13#10 + ' e.preventDefault(); '#13#10 + '} '; grdWorkSheet.ClientEvents.ExtEvents.Add(MyScript); Quote Link to comment Share on other sites More sharing options...
