Question

我有gridview从数据库中检索数据。我没有更新数据ingridview中的语句我做了我的代码，但是当我在gridview中选择编辑选项这个错误apear （过程或函数'Update_IntoModel'期望参数'@Id '，没有提供） 。

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) 
    { 
     int RowAffected = 0; 
     GridView1.EditIndex = e.NewEditIndex; 
     using (SqlConnection con = Connection.GetConnection()) 
     { 
      SqlCommand Com = new SqlCommand(); 
      Com = new SqlCommand("Update_IntoModel", con); 
      Com.CommandType = CommandType.StoredProcedure; 
      Com.Parameters.Add(Parameter.NewInt("@Id", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Model_EN", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Model_AR", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Url", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Resolution_EN", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Resolution_AR", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Warranty_EN", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Warranty_AR", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Dimensions_EN", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Dimensions_AR", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@ContrastRatio_EN", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@ContrastRatio_AR", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Brightness_EN", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@Brightness_AR", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@PanelResposeSpeed_EN", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewNVarChar("@PanelResposeSpeed_AR", GridView1.SelectedValue)); 
      Com.Parameters.Add(Parameter.NewBit("@Active", GridView1.SelectedValue)); 
      RowAffected = Com.ExecuteNonQuery(); 
      if (RowAffected > 0) 
      { 
       LblResult.Visible = true; 
       LblResult.Text = "Successfully Proccess"; 
       Update.Visible = false; 

      }

检查参数@Id这可能导致错误的名称。

还检查您正在传递的参数的数量和过程中没有参数。
