[CLOSED] long-running script

Hello

I have a DirectMethod-function that executes approx. 5 minutes. Called from javascript it causes that after about 30 seconds browser "freezes". In IE there is a message "xyz is not responding due to a long-running script".
Finally, when the execution is finished, browser "unfreezes", but this is not user friendly.
The script saves data from the grid (many rows) to a database and cant be faster.
Is there a way to avoid this message and browser not-responding?

You have two options for this:

1. Send data by chunks, giving user feedbacks often (segment the upload process, checking for errors every checkpoint)
2. Set up an asynchronous task as exemplified here: Assynchronous DirectEvents.

Here are related discussions for further reference:
- AjaxMethod - is it Asynchronous
- Asynchronous DirectMethod

I hope this helps!

Thanks for the reply.
I used DirectEvent instead of DirectMethod but it didn't solve the problem. Then I investigated my code and found a funny bug.
There was a:

Code:

---

ExtNet.AddScript(this.ID + ".getView().refresh();");

---

execuded for each row (on the sever, during the save operation).

I put the code after the loop and now everyhing works like a charm, even with DirectMethod.
It looks like previously the grid was saved in 30 seconds and then browser was stuck executing "getView().refresh" houndres of times.

Yes, glad you found the real culprit of this issue. Refreshing a whole grid for every changed row in a batch change of all rows really is something that would give a lot of strain in the browser, client-side operation.
