What's the javascript equivalent of MasterTableView.IsItemInserted =False

[Paul]

I've done some server side validation on Insert, and then called the confirmation box 

RadWindowManager1.RadConfirm("Are you sure?", "confirmInsertCallBackFn", 330, 100, null, "System Alert");

 

So on my client side I can cancel the user response ...

function confirmInsertCallBackFn(arg) {
                if (arg) {
                    $find("<%=RadGrid1.ClientID%>").get_masterTableView().fireCommand("InitInsert", "");
                    ### NEED TO CLOSE THE INSERT FORM ###
                }
            }

The only issue is that the the Insert form doesn't close when the RadConfirm is OK. What is the java script equivalent of "RadGrid1.MasterTableView.IsItemInserted =False" in order to close the Insert form.

 

I found general guidance here, but the cancelInsert() call actually cancels the Insert altogether and closes the insert form, rather than just close the form.

$find("<%=RadGrid1.ClientID%>").get_masterTableView().cancelInsert();
