如何将列表框项目存储到会话中

问题描述

Hai friends，



我在列表框中有一个疑问。



我创建了一个列表框。它正在填充sql表中的值。它还允许多选择为true。您可以告诉我如何将列表框项值存储在会话中。



我尝试过以下代码：

ASP.NET代码：

Hai friends,

I have one doubt in list box.

I have created a list box.It is populating the values from a sql table.It also allows multi selection to true.Can u please tell me how can i store the listbox item values in a session.

I have tried the below code:
ASP.NET Code:

<tr>
                <td align="right">


                  <asp:Label ID="lblPrimaryImpactedArea" runat="server" Text="Primary Impact Area"></asp:Label>
                </td>
                <td>
                   <asp:ListBox ID="lstPrimaryImpactedArea" runat="server" SelectionMode="Multiple">

                    </asp:ListBox>
                </td>

            </tr>

C＃代码：

C# code:

Session["PrimaryImpactedArea"] = lblPrimaryImpactedArea.SelectedItem.Text;

假如我想将上面的列表框项目用到下一页我尝试了以下代码：



查看下一页的列表框项目：

Suppose if i want to use the above listbox items into next page I tried the below code:

To View the listbox items in next page:

string PrimaryImpactedArea = System.Web.HttpContext.Current.Session["PrimaryImpactedArea"].ToString();
             lstPrimaryImpactedArea.SelectedItem.Text = Session["PrimaryImpactedArea"].ToString();
             lstPrimaryImpactedArea.Enabled = false;

但它不起作用。请帮助我。



先谢谢
