Hello ,
Do you use Batch editing mode?
http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx
Batch editing is a tad specific. You can check the following post for further clarification on Batch editing. There is also sample for external save button implementation:
http://www.telerik.com/forums/radgrid-within-dataform#n5vi8Bq46UaeI2H-tURExg
To wrap it up - the postback to the server should be initiated only by the saveChanges method, which means that you should disable the AutoPostBack property of the button. Then, you can use the BatchEditCommand event handler provided by RadGrid and extract the changes. You can also can call any additional server-side logic within this event handler:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-editing/edit-mode/batch-editing/server-side-api
For detecting and canceling the command action on client-side, you can check the provided explanation in the following post:
http://www.telerik.com/forums/identify-the-button-clicked-in-batcheditcommand#vGZdD79bxkeyYMTYh_ycNg
Here is a live sample with OnUserAction:
http://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/client-side/client-data-source-binding/defaultcs.aspx
If you want to automatically save the changes before commencing some grid action, you should cancel the page, sort, filter, etc. events and then call the saveChanges method explicitly. After that, you can use the FireCommandEvent method on the server:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/control-lifecycle/how-to-fire-command-events
In addition, I am also sending a sample RadGrid web site to demonstrate a similar implementation.
I hope this will prove helpful.

Eyup

Hi Eyup,
I am using Editform.
I want to cancel the "add new" if there is new record which is not saved yet. I do not want to lose any data.
Or Can I hide the "Add new" and bring it back to visible when new record is saved?

Hi ,
Yes, you can achieve both of these implementations. The first one can be achieved using some custom validation, similar to the approach demonstrated in the attached application.
The other can be achieved by accessing the Add new record and hiding it explicitly when the row is opened in edit mode.
