[RESOLVED] [2005] Modify a row and then filter, exception: Index 1 does not have a value

My datagridview is binded to a binding source.

Then I change a value of a cell in column (c) in the first row, and click other rows.

Then I set the filter of the binding source by the other other than the very cell I modified.

The above exception occurs in my RowLeave function.
And this error occurs accidentally.

How I can fix it?

Hi, thanks .

Actually it is just a bug issue, so I mark it resolved after I fix the bug.

After chosing a filter, just one row left, so bindingsource just has 1 row.
But I click the last row( new row), so the index is out of range.

I fix it by adding a judgment of index < bindingsource.count
