My original code is:

        SqlConnection con = DB.createConnection();
        SqlDataAdapter sda = new SqlDataAdapter();
        sda.SelectCommand = new SqlCommand("select * from memo",con);
        DataSet ds = new DataSet();
        sda.Fill(ds, "memo");
        GridView1.DataKeyNames = new string[] {"memoID" };
        GridView1.DataSource = ds.Tables["memo"];
        GridView1.DataBind();
        GridViewRow row = new GridViewRow();
         Give advice.

What are you doing with this! Any functions!
Haven't all the people in gridview already written Microsoft! No need to write a line of code to delete or modify!

Haha, I feel that directly using Microsoft's own binding flexibility is a bit poor, but now I can get the key value, thank you for participating.
