I have a ProcessEvent method which has a RemoteEventType - HandleItemAdded. Since I have some custom functionality in HandleItemAdded function, it takes some time for the associated List item to get submitted.

Is it possible to have a "waiting to complete" dialog appear during this activity? The code is written in Provider Hosted App's App Installed Event done in CSOM.


Sample code below: 

public SPRemoteEventResult ProcessEvent(SPRemoteEventProperties properties) 
{ SPRemoteEventResult result = new SPRemoteEventResult();
        switch (properties.EventType)
        {
            case SPRemoteEventType.AppInstalled:
                HandleAppInstalled(properties);
                break;
            case SPRemoteEventType.AppUninstalling:
                HandleAppUninstalling(properties);
                break;
            case SPRemoteEventType.ItemAdded:
                HandleItemAdded(properties);
                break;
        }


        return result;
    }

Hi,

you can use show wait screen

function RequestEnded(sender, args) {
  try {
    waitDialog.close();
    waitDialog = null;
  } catch (ex) { }
};

function RequestStarted(sender, args) {
   ExecuteOrDelayUntilScriptLoaded(ShowWaitDialog, "sp.js");
};

function ShowWaitDialog() {
   try {
      if (waitDialog == null) {
         waitDialog = SP.UI.ModalDialog.showWaitScreenWithNoClose('Processing...', 'Please wait while request is in progress...', 76, 330);
      }
   } catch (ex) { }
};

Hi,

Actually I am doing this in SharePoint 2013 provider hosted app. So I need something in CSOM(C#). And SPLongOperation is not available in CSOM

Please advise.
