We can also use cross post back property ofASP.NET 2.0
eg:
1. Specify the ListBox as
<asp:ListBox ID="ListBox1" runat="server" >
<asp:ListItem Value="1" Text="1st Option" />
<asp:ListItem Value="2" Text="2nd Option" />
<asp:ListItem Value="3" Text="3rd Option" />
</asp:ListBox>
2. Add this code in the default.aspx(.cs)
public ListBox TheListBox
{
get
{
return ListBox1;
}
}
protected void Page_Load(object sender, EventArgs e)
{
//Generate the cross-page postback script
PostBackOptions options = new PostBackOptions
(ListBox1);
//This will trigger correct script generation
options.ActionUrl = "secondPage.aspx";
//Add it to onchange attribute if the ListBox
string s =
Page.ClientScript.GetPostBackEventReference(options);
ListBox1.Attributes["onchange"]=s;
}
3. Then on secondPage.aspx
3.1 In aspx
<%@ PreviousPageType VirtualPath="~/Default.aspx" %>
3.2 in Page_Load of the secondPage.aspx(.cs)
protected void Page_Load(object sender, EventArgs e)
{
if (PreviousPage != null &&
PreviousPage.IsCrossPagePostBack)
{
Response.Write("You selected " +
PreviousPage.TheListBox.SelectedValue );
}
}
