Hi Ricardo,
Sorry for delay in response
1. I got this message.
Sys.InvalidOperationException: Handler must be a function.We suggest you to set value for "ClientSideOnCellValidate" property as "FunctionName" and do avoid using function braces "()".
2. There isn't any documentation about it.Please refer the below documentation link to get list of ClienSide events and their purposes.
http://help.syncfusion.com/ug_81/ASP.NETUI_Grid/Client-sideEvents.html "ClientSideOnCellValidate's" handler function will be called when cell is clicked in the ExcelEditMode and it will supply an event argument. That have the following properties. Please make use of it
1. e._curVal - Returns Current Cell Value
2. e._preval - Returns Previous Cell Value
3. e.getType() - Returns Current Cell Type
4. e.getCell() - Returns Current Cell element
5. e.cancel - "true": will cancel current cells update when press Save.
Let me know if this meets up your requirement.
Regards,
Bharath
