Question

我是asp.net的新手我最近试图学习如何填充gridview。我已经填充了gridview，但我面临的一个问题是，我绑定到gridview的数据表也显示在屏幕上。我无法弄清楚为什么会这样。请帮忙。

这是我的.cs文件

        protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {

            bindgrid();
        }
    }


    private void bindgrid()
    {
        DataTable table = new DataTable();
        table.Columns.Add("AmountPrice");
        table.Columns.Add("Currency");
        table.Rows.Add("12000", "USD");
        table.Rows.Add("11000", "Rupees");
        table.Rows.Add("12344", "AED");


        Session["gridTable"] = table;
        GridView1.DataSource = table.DefaultView;
        GridView1.DataBind();
    }

    protected void add_Click(object sender, EventArgs e)
    {
        DataTable table1 = (DataTable)Session["gridTable"];

        GridViewRow row = (GridViewRow)((sender as Button).NamingContainer);

        TextBox tbamount= (TextBox)row.FindControl("txtAmount");
        TextBox tbcurrency = (TextBox)row.FindControl("txtCurrency");
        Button add = (Button)row.FindControl("add");

        string vamount = tbamount.Text;
        string vcurrency = tbcurrency.Text;

        table1.Rows.Add(vamount, vcurrency);

        GridView1.DataSource = table1.DefaultView;
        GridView1.DataBind();
        Session["gridTable"] = table1;
    }

这是我的.aspx文件
