This is a master page code

Connection cn = new Connection();
SqlDataAdapter adp;
appointment ap = new appointment();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{

}
}
protected void grdview_RowEditing(object sender, GridViewEditEventArgs e)
{
MasterPage mp = this.Master;
GridView gvowner = (GridView)mp.FindControl("grdview");
gvowner.EditIndex = e.NewEditIndex;
ap.Ownerbind();

}

Do not post such of code in comment! Use "Improve question" widget instead!

Everything looks fine. Not sure why you are getting exception.
One of the possible cause can be your content page may be not a child of the master page you are looking at.

You can try other methods to find master page controls and see if that works.
