Whenever the java script call this method cell.endEdit(true), the event stop at this line
try{result=eval(eventObj[0]+eventString);}catch(ex){return false;}
in the above event handler.
The value for eventObj[0] is "UltraWebGrid1_EditKeyDownHandler" and the eventString is ("UltraWebGrid1","UltraWebGrid1_rc_0_0",9). How come the eval statement does not work. The ex name is "TypeError". The ex description and dessage are the same - "Object does not support this property or method."
Hello,
This one is a bit hard to tell without seeing the setup of the grid and the body of the EditKeyDownHandler client-side event handler. There is a possibility that the custom javascript code that you have used in EditKeyDownHandler produces the javascript event handler.Or maybe the actual event handler is not defined in HTML, it is tough to say. The "Object does not support..." error is the most common generic javascript error and it could happen for a number of reasons.
Any additional information you share would certainly provide additional clues.
