I am tryting to create a session variable where I can store a previous page information if I move on to the next page.
For example, I selected bunch of ddls on Customer page, then moved on to Employer page.
w/o session varibles, the information on customer page would be gone.
I am trying to make it where the things i have selected will still appear when i come back to customer page.
Do you guys have any idea how to do this?
If it's a multiselect listbox, I'd simply create a session variable, that had your selections, as a comma delimited string on the changed events, and doing a string split in your current page, and updating everything on the form-load of the new page.
I'm assuming that this is for an ASP .NET application.
You can put objects straight into Session- you just have to cast them when you pull them out of Session.
The following example is for dealing with a List<string>
HTHCode:private List<string> m_StringList;
protected void Page_Load(object sender, EventArgs e)
{
if (Session["StringList"] != null)
m_StringList= (List<string>)Session["StringList"];
}
private void AddStringToList(string item)
{
m_StringList.Add(item);
Session["StringList"] = m_StringList;
}
