I have found my answer. Sorry for the post.

While searching in DataGridView events, I found an event RowPrePaint and just three lines of code of this event solved the problem.

Thanks for viewing my post and also sorry for wasting your valuable time by missing the event.

DataGridView.RowPrePaint event will be raised every time when datagridview must be repainting.
This will happened for example when you drag over datagridview another form or MessageBox
or when you minimize/hide form and reopen it again...

In your case you need update Serial No only after count of the rows was changed.

Method Dgv_RowCountChanged will be executed in the event handlers of RowsAdded and RowsRemoved

Here is how to create a Column index autogenerate serial number of each row:

Then on the codebehing:

Vb Concatenate Strings

Vb Net Datagridview Add Row

This code works as same when we apply paging.

We cannot use this on BoundFields because they support only those objects who have Databinding event

Using Datagridview Vb
