is it OK to do a nested try/catch?

Hi,

I am getting this error, "Index was outside the bounds of the array"
So I can guess that this is coming out ofthe array/list/ in my case, I think it is coming from the listview.

There is several sections of the code and one try/catch to capture an exception.

Is it ok to insert more try/catch into those small sections of the code to where exactly the error is coming from?
I still this overall try/catch where there is one function from the final{}.
