            dataGridView1.DataSource = DC.dataSet;
            dataGridView1.DataMember = "orderList";

//delete Button click event
try
{
    DialogResult dr = MessageBox.Show("Do You want to delete the product details?", "Confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
    if (dr == DialogResult.Yes)

你需要编写代码在if条件下从数据库中删除。

hi
you need to write code to delete from database within if condition.

在删除按钮上单击尝试从数据库中删除数据。

然后检索数据并绑定到网格。

On delete button click try to delete data from database.
Then retrieve data & bind to grid.

添加dataGridView1.databind（）;

add dataGridView1.databind();
