grid attachEvent on Special only.

hi:
mygrid.attachEvent(“onRowDblClicked”, function(rId,cInd){
if(cInd==1){
mygrid.cellById(rId,cInd).setValue(“111”);
}
});
i use the above code to attach the Event on the colum one of the gird.after i double clicked on the other cells ,the cells cannot be edited.
i want to use one colums for event only.how could i do it?

            thanks!

Event handler must return true to allow default processing

mygrid.attachEvent("onRowDblClicked", function(rId,cInd){ if(cInd==1){ mygrid.cellById(rId,cInd).setValue("111"); } return true; });
