如何將我的 gridview 數據傳輸到另一個 aspx 頁面？

Question

向內.aspx

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="pono" DataSourceID="SqlDataSource1" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">
        <Columns>
            <asp:CommandField SelectText="Update" ShowSelectButton="True" />
            <asp:BoundField DataField="pono" HeaderText="pono" ReadOnly="True" SortExpression="pono" />
            <asp:BoundField DataField="podate" HeaderText="podate" SortExpression="podate" />
            <asp:BoundField DataField="partyname" HeaderText="partyname" SortExpression="partyname" />
            <asp:BoundField DataField="flag" HeaderText="flag" SortExpression="flag" />
            <asp:BoundField DataField="itemnm" HeaderText="itemnm" SortExpression="itemnm" />
            <asp:BoundField DataField="indt" HeaderText="indt" SortExpression="indt" />
            <asp:BoundField DataField="qty" HeaderText="qty" SortExpression="qty" />
        </Columns>
    </asp:GridView>

向內.aspx.cs

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
    string pono = GridView1.SelectedRow.Cells[0].Text;
    Response.Redirect("Update_inward.aspx?pono="+pono);
}

update_inward.aspx.cs

protected void Page_Load(object sender, EventArgs e)
{
    string stcon = ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString;
    SqlConnection con = new SqlConnection(stcon);
    con.Open();
    String query = "Select * from maxus_in where pono=" + Request.QueryString["pono"];
    SqlCommand cmd = new SqlCommand(query, con);
    SqlDataAdapter sda = new SqlDataAdapter(cmd);
    DataSet ds = new DataSet();
    sda.Fill(ds);
    if (ds.Tables[0].Rows.Count > 0)
    {
        TextBox1.Text = ds.Tables[0].Rows[0]["pono"].ToString();
        TextBox2.Text = ds.Tables[0].Rows[0]["podate"].ToString();
        TextBox3.Text = ds.Tables[0].Rows[0]["partyname"].ToString();
        TextBox4.Text = ds.Tables[0].Rows[0]["itemnm"].ToString();
    }
    con.Close();


}

我如何傳輸這些數據並在另一個頁面的文本框中顯示？

Answer 1

您可以使用查詢字符串或在會話中存儲值並在下一頁的頁面加載時檢索值。

username.Value = Request["用戶名"]; username.Value = Session["username"].toString();
