Answer 1

If grid row has label with id lblName then you will get it from row and you do not need to check it again.

foreach (GridViewRow row in gvName.Rows)
{
    Label lblName = (Label)row.FindControl("lblName");         
    lblName.Text = txtName.Text;            
}

Note: If you do not have rows already in thr gridview then you wont be able get the value in label. You need to ensure their are row(s) in grid.
