本文介绍了一个使用ASP.NET中GridView控件实现数据展示、编辑、更新和删除功能的示例。通过具体的代码片段展示了如何初始化GridView并绑定数据源，以及如何处理用户触发的编辑、取消编辑、更新和删除操作。

 protected void init()//初始化数据
    {
        GridView1.DataSource = DBHelper.GetDataTable("select * from Pro_Units");
        GridView1.DataBind();
    }

    protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {//编辑
        GridView1.EditIndex = e.NewEditIndex;
        init();
    }

    protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {//取消
        GridView1.EditIndex = -1;
        init();
    }

    protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {//更新
        string str = GridView1.Rows[e.RowIndex].Cells[0].Text.Trim();
        string name = ((TextBox)GridView1.Rows[e.RowIndex].Cells[1].Controls[0]).Text.Trim();
        DBHelper.ExecutCommand("UPDATE [Pro_Units] SET [uintsName] ='"+name+"' WHERE id=" + str);
        GridView1.EditIndex = -1;
        init();
    }

    protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {//删除
        string str = GridView1.Rows[e.RowIndex].Cells[0].Text.Trim();
        DBHelper.ExecutCommand("DELETE FROM [Pro_Units] WHERE id=" + str);
        GridView1.EditIndex = -1;
        init();
    }
