Determine if grid has changes, server side

[Samuel]

I'm developing sharepoint web parts using Telerik controls as a base. I have a web part that drops a Telerik RadGrid onto a page with data in it, and automatically sets all rows to be in edit mode server side before the web part is rendered. There is a button on the web part that the user clicks to save their data.

When the data comes back, server-side, I need to determine if the user has actually made any changes, and if they have, which rows they have changed. My current method is to get all rows and compare their values to their "SavedOldValues." Is there a simpler, or more important, a more performant way to do this?

Hi,

Here is a demo link that performs a similar functionality though the changes are being tracked on the client.
The  global variable is set to true false  based on changes in the edit form controls

Give it a try and let me know if this works for you.

Thanks,
Princy

I think this is it: http://www.telerik.com/help/aspnet-ajax/grid-going-into-edit-mode-with-ajax-double-click.html

Seems to work quite well with the new UserAction option (if you're not using Batch editing):

            function UserAction(sender, args) {

                if (hasChanges && 
                    !confirm("Any changes will be lost. Are you sure?")) {
                    args.set_cancel(true);
                }
            }

 I haven't un-set the value yet, but should be ok to run a "RegisterStartupScript" after clicking "Save Changes" button.

Hi Peter,

I'm glad you've managed to find out about the OnUserAction event and thank you for sharing your approach with our community. For other commands, you can also use the OnCommand event handler provided by RadGrid.

Can you provide an update to this link?

It does not seem to work.
