我正在使用启用编辑和更新的网格视图，并使用UpdateCommandinSqlDataSource更新数据。但是每当我尝试更新记录时，我都会遇到异常

函数或过程指定的参数过多

代码： 

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();
    }
}

ASP.NET：

在以下行中：

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

返回 CheckBox Text 不是 checkBox 值，而是使用这个

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