how to handle the menu control, gridview, and postback...this is driving me nuts!

[John Smith]

If anyone can help, I would very muchly appreciate it.

I have a main page that uses the .net 2.0 menu control with the multiview
controls as the menu choices. This works fine. One of the menu choices
dynamically loads a user control with a gridview (datagrid) control on it.
That works fine. The problem arises when the user clicks on a different
page of the gridview control---this is a paged gridview. When that happens,
the gridview goes away. I'm assuming this is happening because the
"OnPageIndexChanging" event is causing a postback and the user control
doesn't feel like loading after that. I have tried all kinds of things to
make this work.....loading the control at various stages (pageload,
pagerender, etc)....to no avail. It just won't work for me.

I would appreciate any help in solving this. I am beyond giving up on it as
well. Relevant code is below:

masterpage.aspx

<%@ Page Language="C#" %>
<%@ Register TagPrefix="rgp" TagName="showTickets" Src="showTickets.ascx" %>

string strDBView;

protected void Page_Load(object sender, EventArgs e)
{
string strMenuLabel;

if (!IsPostBack)
{
for (int index = 0; index < mvTicketMan.Views.Count; index++)
{
strMenuLabel =
mvTicketMan.Views[index].ID.ToString().Replace("vw", "").Replace("_", " ");
mnuTicketMan.Items.Add(new MenuItem(strMenuLabel,
index.ToString()));
}
mnuTicketMan.Items[0].Selected = true;
}
}

protected void mnuTicketMan_MenuItemClick(object sender, MenuEventArgs
e)
{
Control ctrlShowTickets;

mvTicketMan.ActiveViewIndex = Int32.Parse(e.Item.Value);
strDBView =
mvTicketMan.Views[Int32.Parse(e.Item.Value)].ID.ToString().Replace("vw",
"").Replace("_", " ");

if (strDBView == "My Tickets")
{
ctrlShowTickets = LoadControl("showTickets.ascx");
plhShowTickets.Controls.Add(ctrlShowTickets);
//((showTickets)ctrlShowTickets).DBView = strDBView;
//((showTickets)ctrlShowTickets).BindDataGrid("Ticket_Number");
}
}
