Thats what the first invalidate does! When you call invalidate, it wont invalidate immediately. If you were to call refresh() then it would go straight to the paint code, but this way it just carries on executing the next instruction.

DataRow Dr = dtDetails.NewRow();
Dr["Position"] = ???
Dr["Isin"] = ???
Dr["Bond Price"] = ???
Dr["Cusip"] = ???
dtDetails.Rows.Add(Dr);
