jqGrid response after Add/Edit/Delete?

You needn't do any Java/Spring logic. You will be doing add/update/delete operation in the AJAX call(may be using Jquery) ..
1) Place a <DIV it="myStatus"> just above the table, which can display your add/update/delete status
2) Based on the response of your AJAX call, decide your message

for example if AJAX call failed for ADD

if(failed){
document.getElementById("myStatus").innerHTML="Failed to add the record"
}

As Nithyanandhan said is correct !!

ur using jGrid define in jsp that time u can define the div tag ....


Other wise u can set msg (succes or failer ) in ur controller at request scope

and u can get the  resuest scope variable in JSP using JSTL tag ....

Thanks guys, but what i am looking for is displaying the message on the form pop-up not the actual page.

then its simple..

do this in your javascript...

var status = <your AJAX call response>;

if(status){
alert("Your operation failed");
}else{
alert("Your operation completed successfully");
}

if you want to do a popup window instead of alert  then you can use window.open

want to show it on the form itself not as a alert or a pop-up.

what do you mean by "form itself"?
Early you have mentioned "form pop-up"...

Do you have a form in a pop-up and want to display the message there? In that case you can do the same logic which I mentioned... using <DIV>
logic doesn't change based on your target place for message display...

Please make your statements clear.. it will save both of our time!!
