編集と更新を有効にしてグリッドビューを使用し、 を使用しUpdateCommandてSqlDataSourceデータを更新しています。しかし、レコードを更新しようとするたびに例外が発生します

関数またはプロシージャに指定された引数が多すぎます

コード： 

using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;

public partial class Manager_UnApprovedActivites : System.Web.UI.Page
{
   protected void Page_Load(object sender, EventArgs e)
   {
   }

   protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
   {
        string id = GridView1.DataKeys[e.RowIndex].Value.ToString();
        string Appproval =     ((CheckBox)GridView1.Rows[e.RowIndex].Cells[9].Controls[0]).Text;
        SqlDataSource1.UpdateParameters["id"].DefaultValue = id.ToString();
        SqlDataSource1.UpdateParameters["approval"].DefaultValue = Appproval.ToString();
        SqlDataSource1.Update();
    }
}

次の行で：

  string Appproval =     ((CheckBox)GridView1.Rows[e.RowIndex].Cells[9].Controls[0]).Text;

CheckBox Text ではなく checkBox 値を返す、代わりにこれを使用します

CheckBox chb= ((CheckBox)GridView1.Rows[e.RowIndex].Cells[9].Controls[0]);             
if (chb != null)
            {
                SqlDataSource1.UpdateParameters["approval"].DefaultValue =chb.Checked;
            }
