Question

我正在使用gridview开发webform。我有一个问题，复选框的值不保存在表中。我已经尝试过一切都没有用。按下按钮后，值不会存储。正如你在我的代码中看到的那样，我没有使用id来识别每个特定行，而不是id我使用foreach

protected void Button_Submit_Onclick(object sender, EventArgs e)
     {
         foreach (GridViewRow row in GridView2.Rows)
         {
             con.ConnectionString = ConfigurationManager.ConnectionStrings["TestDeductionsConnectionString2"].ToString();

             bool private1 = (row.FindControl("CheckBox1") as CheckBox).Checked;
             SqlCommand cmd = new SqlCommand("insert into DetailCosts(private) values(@private1)", con);
             if (private1 == true)
             {
                 cmd.Parameters.Add(new SqlParameter("@private1", SqlDbType.Bit));
                 cmd.Parameters["@private1"].Value = 1;
                 //cmd.Parameters.Add("@private1", SqlDbType.Bit).Value = 1;
             }
             else
             {
                 cmd.Parameters.Add(new SqlParameter("@private1", SqlDbType.Bit));
                 cmd.Parameters["@private1"].Value = 0;
                 //cmd.Parameters.Add("@private1", SqlDbType.Bit).Value = 0;
             }
             con.Open();
             cmd.ExecuteNonQuery();
             con.Close();
         }}

我的Gridview有一个代码：
