Sandboxed code execution request failed while storing data in list

Question

I am developing this sandbox webpart for office 365.

I am having 5 row in grid.

This grid is having 3 drop-down and 2 text-box in each row.When I save this grid data to SharePoint list, it works fine.

But when rows of grid get increased from 5 it gives me an error of Sandboxed code execution request failed.

I am facing this issue on pre-production and production office 365 site.

How can I store this data and resolve this issue ?

Any suggestion is welcome and appreciable.

First: Sorry my english, i learn it from internet.

The "Sandboxed code execution request failed." is a general error.

If you have any error in your code, you get this error.

I have two way solve this errors:

1, Make a new "Log" list, and make try-catch bloks in my code. If I catch exception, I write it to the "Log" list, then I see what a really problem.

2, Sometimes the webpart it's fine, but i cant add the Web. I open the Shareoint Designer, and I give the webpart manual.

• First make an Empty web part. (It is easy add to Web, I add this instead of MyWebPartName).
• Then I open the Web in Sharepoint Designer, then the Page(aspx). On the page search the Empty web part, and replace the "TypeFullName" attribute from Emtpy to MyWebPartName.
• If it is not work, sure the problem in your code.

EDIT: 3, The most simple way:

• Make a feedback div. (Simple div, with custom id.)
• Catch the error, and write the ex.Message to my div.

It's work for me.
