Hi,



I am using dhtml xgrid with DataProcessor, I have a problem like I need to check each and every cell after onCellEdit with respect to empty or not empty.

I am getting the data from Database that which column is NULL and which column is NOT NULL. so I would like to add an hidden property/property like nullable to each header column and when onCellEdit I wants to get the value of nullable and do the validation respect to the cell using nullable variable. if condition pass/fail I want to display en alert message.



Can u please help me inthis regard, how to solve this problem?



Is there any function like we are adding column id using setColumnIds(), to do the above one?



/Thanks

Raj

You can store necessary info in userdata sections




 
 …
 
 null
 not null
 …
 
 
 
mygrid.attachEvent(“onEditCell”,function(stage, id, ind, value){
 if (stage==2 && mygrid.getUserData("",“column_”+ind) && value=="")
  alert(“value not valid”);
 
 return true;
})
