Batch edit changes server side

[Mitch]

if save changes is never invoked client side, can we get the changes made to a batch edit radgrid server side? we'd like to eliminate the need to click 'save changes' and have the whole form (grid and non grid fields) submitted by a single action.

if i call savechanges thru javascript automatically on submit, is there some way to ensure it executes first?

$(document).ready(function () {
            // do radgrid save on form submit
            var originalSubmit = document.forms[0].onsubmit;
            document.forms[0].onsubmit = function () { SaveChangesInGrid(); onsubmit; }
        });
        
        function SaveChangesInGrid(sender, args) {
            $find('<%=rgAffectedOther.ClientID%>').get_batchEditingManager().saveChanges(grid.get_masterTableView());
        }

Hello Mitch,

Actually you may experience problems when following this approach. If the postback does not get initiated by the batch editing manager the user changes will not be sent to the server. That said I would recommend calling the saveChanges method when a button is clicked thus transferring the grid changes the server. Later you can access them inside the OnBatchEditCommand handler alongside with the other form elements values.

is there any way to ensure a call to savechanges finishes before the form is allowed to submit? it seems when I call savechanges immediately before form submit, it sometimes executes first and sometimes second.

Hello Mitch,

In order to ensure that the saveChanges method gets called I would recommend modifying the logic so that the button which triggers the postback calls the method.

ASPX:

<script>
            function SaveChanges() {
                var grid = $find('<%=rgAffectedOther.ClientID%>');
                grid.get_batchEditingManager().saveChanges(grid.get_masterTableView());
            }
        </script>
        <asp:Button Text="Save Changes" OnClientClick="SaveChanges(); return false;" runat="server" />

By following the above approach you should be able to make things work as expected.
