Validating the element which is opened while editing a cell

Hi,

I am using dhtml grid in which a cell is editable.
Now, I would like to validate the values in the Text area which is opened while double click on the editable cell.

Conditions:

1. The text area should not have blank value when TAB key is pressed or Text area lose its focus.


Thanks in advance for your help.

You can use "onEditCellEvent":

mygrid.attachEvent("onEditCell",function(stage,rowId,cellInd,newValue,oldValue){

if ((stage==2)&&(newValue=="")) {//if editor is closed and newValue is empty

alert("value is empty");

}

})
