DataGridView 不保存到数据库
DataGridView not saving to database
我正在创建一个简单的员工目录程序,我正在制作它以便用户可以更新目录。但是,当前将数据添加到 DataGridView 时,它不会保存到数据库中。我知道 this.staffTableAdapter.Update(this.dBDataSet1.Staff);
是必需的,它在我的程序中,如下所示。
我只是不确定我现在错过了什么,如果有人能帮助我,我将不胜感激。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace StaffDirectory
{
public partial class Administration : Form
{
public Administration()
{
InitializeComponent();
}
private void staffBindingNavigatorSaveItem_Click(object sender, EventArgs e)
{
this.Validate();
this.staffBindingSource.EndEdit();
this.staffTableAdapter.Update(this.dBDataSet1.Staff);
}
private void Administration_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'dBDataSet1.Staff' table. You can move, or remove it, as needed.
this.staffTableAdapter.Fill(this.dBDataSet1.Staff);
}
}
}
您应该添加 try-catch
块和 analyze/provide 我们以及异常描述 (ex.Message
):
private void staffBindingNavigatorSaveItem_Click(object sender, EventArgs e)
{
try{
this.Validate();
this.staffBindingSource.EndEdit();
this.staffTableAdapter.Update(this.dBDataSet1.Staff);
}
catch(Exception ex) {}
}
此外,添加this.dBDataSet1.Staff.AcceptChanges()
