Check if event was cancelled after calling client side updateItem

[Hosney]

Is there a way to find out if the event was cancelled on the server after calling grid table view updateItem method from the client?

Hello Hosney,

I am afraid it is difficult to figure out your exact scenario by the provided information so far. Could you please elaborate on what you want to achieve?

Generally, you could use the OnItemUpdated server event of RadGrid to check whether the update has been successfully performed as demonstrated in the following demo:

I hope this will prove helpful.

I'm calling the following function from the client:

masterTableView.updateItem(editIndex);

Then I capture the OnUpdateCommand event on the server to perform the update. Here I do some validations and if the data is invalid i cancel the event by setting e.Canceled = true; (where e is the GridCommandEventArgs parameter)

What I'd like to know is if there is a method called back on the client after this where I can check if the UpdateCommand was cancelled.

I'm doing something similar to what can be found here:
http://mono.telerik.com/Grid/Examples/DataEditing/EditOnDblClick/DefaultCS.aspx

Only difference being that I do the saving manually inside the UpdateCommand event, and cancel the event based on the validity of the record. But cancelled or not the editedRow variable will be set to null and the next row click will not fire the updateItem function.

Hi Mohamed,

I am afraid there is no a direct callback function when you cancel the update operation. Instead, you could fire a JavaScript function when you use e.Cancel= true or OnItemUpdated, which is being fired if the actual update has been performed:

ScriptManager.RegisterStartupScript(Page, typeof(Page), "myScript", "functionName()", true);

I hope this helps.

I thought so. That's not so hard anyway. Thanks!
