如何使用 TableAdapter 进行更新?

How to update with TableAdapter?(如何使用 TableAdapter 进行更新?)

问题描述

我正在 WindowsApplication 中编写一个使用数据库的程序.我用 DataGridView 显示数据库值.目前，我希望有可能通过 DataGridView 更新数据库，因此我编写了以下代码:

I'm writing a program in WindowsApplication which use database. I display the database values with DataGridView. Currently, I want that there would be a possibility to update the database through the DataGridView, therefore I wrote this code:

    private void MainForm_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'databaseDataSet1.products' table. You can move, or remove it, as needed.
        this.productsTableAdapter1.Fill(this.databaseDataSet1.products);
    }

    private void upButton1_Click(object sender, EventArgs e)
    {
        this.productsTableAdapter1.Update(this.databaseDataSet1.products);
        MessageBox.Show("הנתונים עודכנו בהצלחה!");
    }

问题是没有将值更新到数据库中.如果有人能帮我解决这个问题，或者更好地解释如何使用 DataGridView，我会很高兴，因为我在互联网上没有找到任何有用的东西.

The problem is that there is no update of the values into the database. I'll be happy if someone could help me solve this problem, or even better, explain how to work with DataGridView, because I haven't found anything useful on the internet.

推荐答案

        this.Validate();
        this.productsBindingSource.EndEdit();
        this.productsTableAdapter1.Update(this.databaseDataSet1.products);
        //this.productsTableAdapter1.UpdateAll(this.databaseDataSet1);
