How to use SharePoint notification from Event Receiver

Question

I have an event receiver, which fires when item is being deleted ( ItemDeleting event ). I have some logic that checks whether item can be deleted or not, and if it can't, I need to show notification message - reason why item can't be deleted.

Now I would like to use SharePoint notifications, to have notification appear on the upper right corner, under the ribbons panel.

Any ideas how can I do that ? Or is it even possible ?

Answer 1

The only way you can get the call of the Javascript from the EventReceiver to the browser is through the SPEventPropertiesBase.RedirectUrl, but unfortunately you can't just specify javascript:... so you may have to:

• Add something to your master page looking for a query parameter and showing the notification if that query parameter is present
• In the EventReceiver set RedirectUrl to the original Url + the special query parameter

You should check it this code works as you want in all scenarios like when the users open an item in a dialog box (view/edit) and clicks delete, ...
