stay edit mode on server side validation fails

[Soori]

Hi,
I am sending an ajax request inside datasource update method. How can stay in edit mode if this request fails ?

Following is a sample code snippet of mine .

 this._datasource = new kendo.data.DataSource({
              transport: {
                create: create,
                read: read,
                update: update,
                destroy: destroy
            }
})

  function update(options) {
                that._api.put(resource, inputData)
                    .done(function (data) {
                  
                    })
                    .fail(function (error) {
                             that._datasource.cancelChanges();
                    });       
        }

Hello Charith,

The Grid should not close until the success function of the arguments object is not invoked. Here is a small demo:

Feel free to modify the example and share if you have different setup. Let me know if I missed something

Thanks Petur . But the problem is with ListView . Save event fires before update process finishes .

Hello Chartih,

My apologies I forgot that detail. Indeed when using the ListView it will close the edit mode immediately after starting the request (so the edit mode will be closed before the response is sent to the client). So you can prevent the save event of the ListView. The same question is discussed here:

http://www.telerik.com/forums/keep-listview-in-edit-mode-after-server-side-error

The DataSource will anyway trigger a change event and the ListView will successfully close edit mode if the response will "successful save".

I hope this helps.
