            ff.Rows.Add(row);
            txt_reciptno.DataBindings.Add("text", row, "Regno");

Answer 1

Why are you using DataTable ?? you can simply get rg via your query and then set the text property to rg + 1, something like following:

 text_recpitno.Text = (rg + 1).ToString();

Answer 2

Agreed with @Habib.OSU. But for the binding, try this:

txt_reciptno.DataBindings.Add("text", ff.DefaultView, "Regno");

Answer 3

I hope this article could help you. Data Binding in .Net

And in your case you need

txt_reciptno.DataBindings.Add("Text", ff, "Regno");

If you want to move to the next row , you should use

 var myCurrencyManager = (CurrencyManager)this.BindingContext[ff];

 myCurrencyManager.Position ++;
