search from gridview in C#

Question

when I am searching  for some records in gridview, the error message is showing like

"Specified argument was out of the range of valid values"

the code is:

con.Open();

string query = "select Name from View where ID like'" + txtID.Text +"%'";

            SqlDataAdapter da = new SqlDataAdapter(query, con);

            DataSet ds = new DataSet();

            da.Fill(ds);

            if (ds.Tables[0].Rows.Count > 0)

            {

                GridViewItm.DataSource = ds;

                GridViewItm.DataBind();

                GridViewItm.Show();

            }

            else

            {

                Response.Write(@"<script language='javascript'>alert('Requested Records Not Found')</script>");

            }
