How to implement AsyncCallback when importing rows?
I never use `AsyncCallback`. Need your help.

When In Windows Form app I importing rows application form freezes. To prevent it, i think I can use `AsyncCallback`.

    foreach (DataRow dr in srcdt.Rows)
    {
        desdt.ImportRow(dr);
    }

and while importing rows, to show in `lebel.Text` imported row count.
Some help please.
