2013 - deleting event receiver programatically using c#

2 hours ago

3 Answers 3 3 Answers 3 1 It's mostly likely because you already have an instance of the SPList (from another context) before you try to execute the deletion of an EventReceiver. That's why the ThreadAbortionException is thrown. Instead of sending in the list, send its name instead and get the list inside the RunWithElevatedPrivileges codeblock. private void RemoveEventReceiver(string listName, bool isRemove) { // No need to continue if it's FALSE if (isRemove) return; SPSecurity.RunWithElevatedPrivileges(() => { using (var site = new SPSite(SPContext.Current.Site.ID)) { using (var web = site.OpenWeb()) { // Get the list with elevated permissions var list = web.Lists.TryGetList(listName); try { web.AllowUnsafeUpdates = true; foreach (SPEventReceiverDefinition eventReceiver in list.EventReceivers) { if (eventReceiver.Type == SPEventReceiverType.ItemUpdating) { eventReceiver.Delete(); } } // Update the list after the iteration is complete. list.Update(); } catch(Exception ex) { //... } finally { // Remember to set AllowUnsafeUpdates to false again when you're done. web.AllowUnsafeUpdates = false; } } } }); } Follow answered Jun 30 '15 at 12:44 user2536user2536 | 2 I would try the following: Get the List again from the elevated Web instead of the instance you pass to this method. Try searching your eventreceiver additional by assembly or classname to make sure you don't delete some SharePoint internal Receiver. finally{ web.AllowUnsafeUpdates = false;} Follow answered Jun 30 '15 at 12:22 Gwny 1,22411 gold badge77 silver badges1616 bronze badges | 0 Also, it looks to me like you are trying to modify a collection while iterating through it. I would try a regular for/next loop going from (SPList.EventReceivers.Count - 1) to 0. And you do need to get the list again from an elevated web. Which you get from an elevated site (I always indicate the SystemAccount token specifically for clarity): string ListName="<Title of List>"; SPSecurity.RunWithElevatedPrivileges(delegate () { using (SPSite site = new SPSite(web.Site.ID, SPUserToken.SystemAccount)) { using (SPWeb elevatedWeb = site.AllWebs[web.ID]) { elevatedWeb.AllowUnsafeUpdates = true; try { SPList list = elevatedWeb.Lists[ListName]; int numEventReceivers = list.EventReceivers.Count; int topIndexOfEventReceivers = numEventReceivers - 1; for (int i=topIndexOfEventReceivers;i>-1;i--) { SPEventReceiverDefinition eventRecieverDefinition = list.EventReceivers[i]; eventRecieverDefinition.Delete(); } list.Update(); } finally { elevatedWeb.AllowUnsafeUpdates = false; } } } }); Follow answered May 18 '18 at 18:44 towkneed 4144 bronze badges |
