Solution 1

Use the Session to Achieve this like

C#

//Store Items in a Session
        Session["ListViewStore"] = lv.Items;
//Fetch back with required data type in next page and set the fetched source to listbox.
        List<ListViewDataItem> fetchback = (List<ListViewDataItem>)Session["ListViewStore"];

Solution 2

If it's not adding in second page check if session variable is null or not

C#

if (Session["ListViewStore"] != null)

Adding same code mentioned in my comment below.

C#

if (Session["ListViewStore"] != null) 
{ 

System.Web.UI.WebControls.ListItemCollection list = (System.Web.UI.WebControls.ListItemCollection)Session["ListViewStore"]; 

foreach (ListItem item in list)
 { 
ListBox2.Items.Add(item);
 } 
}

k kept but coming this error Unable to cast object of type 'System.Web.UI.WebControls.ListItemCollection' to type 'System.Collections.Generic.List`1[System.Web.UI.WebControls.ListViewDataItem]'.

@Hiren-I am sorry ,will take care in future. @1nagaswarupa-Are you using Paging in ListView & want to show same 3 items in second page of same ListView?Your question says like this "i want display that 3 items in another page of listbox" .It's a bit confusing.

Rupa1 13-Jan-11 2:15am

i ve one listbox in default.aspx it having some items, i want display the same items of listbox in default2.aspx

Anupama Roy 13-Jan-11 3:38am

It throws exception because the casting is wrong.I worked out a snippet for you.This will work

if (Session["ListViewStore"] != null)
{
System.Web.UI.WebControls.ListItemCollection list = (System.Web.UI.WebControls.ListItemCollection)Session["ListViewStore"];
foreach (ListItem item in list)
{
ListBox2.Items.Add(item);
}
}

Store the listview object in the session not the items as

Session["sListView"]=lv;

Then you can access the Listview session in the next page

ListView lvList=(ListView)Session["sListView"];

lvList you will get the exact copy of lv Listview in the first page.

Hope this will help you :). I didn't tried the code for a trial.
