sharepoint 2019 event receiver is not firing

Question

We have a provider hosted app deployed which used to upload/ modify/ delete documents into document library. We have deployed a ItemDeleting event receiver (not RER) into document library. Event receiver is not firing when the item is deleted from provider hosted app web however it works if any document is getting deleted directly from SharePoint library. Would like to know why the event is not getting fired when the item is deleted from app web?

Hi @Raja ,

I tested with the code snippet below to delete a file item in host web from Provider Hosted Add-in:

private void DeleteItem(int id)
{
try
{
var spContext = SharePointContextProvider.Current.GetSharePointContext(Context);

using (var context = spContext.CreateUserClientContextForSPHost())
{

Web web = context.Web;

List oList = web.Lists.GetByTitle("Doc3");

Microsoft.SharePoint.Client.ListItem oListItem = oList.GetItemById(id);

oListItem.DeleteObject();

context.ExecuteQuery();

}
}
catch (Exception ex)
{
throw ex;
}
}

It's triggering ItemDeleting event by debugging with break point:

I suggest you can try to debug Event Receiver with break point to see if it triggered event or not.

And here is a reference to access host web data in Provider hosted add in for your reference:
