Tabstrip SelectedIndex reverting to 0 on page load

[Dave]

Greetings,

I am using a tabstrip in a user control (ascx) in a web application (aspx)
that is used to navigate between the different aspx pages. Whenever I click
on one of them, the response.redirect command works fine, but the page
reloads with the first tab selected every time. If I try to change the
selectedindex, it runs my SelectedIndexChanged routine so that doesn't work
either.

Is there a way I can change the selectedindex of the tabstrip without
running the "OnSelectedIndexChange" command?

Below is my code:

Sub TabStrip_PIP_SelectedIndexChange(sender As Object, e As EventArgs)
Select Case Tabstrip_PIP.selectedindex
Case 0
Response.Redirect("ProjectSummary.aspx")
Tabstrip_PIP.selectedindex = 0
Exit Sub
Case 1
Response.Redirect("ChargeNumbers.aspx")
Exit Sub
Case 2
Response.Redirect("Invoices.aspx")
Exit Sub
Case 3
Response.Redirect("Labor.aspx")
Exit Sub
Case 4
Response.Redirect("Travel.aspx")
Exit Sub
Case 5
Response.Redirect("ODC.aspx")
Exit Sub
Case 6
Response.Redirect("Subcontracts.aspx")
Exit Sub
Case 7
Response.Redirect("PurchaseOrders.aspx")
Exit Sub
Case 8
Response.Redirect("ChargeSummary.aspx")
Exit Sub
End Select
End Sub
<iewc:tabstrip id="TabStrip_PIP" runat="server" autopostback="true"
Height="26px"

<iewc:Tab Text="Labor"></iewc:Tab>

<iewc:Tab Text="Purchase Orders"></iewc:Tab>

Thanks for your help,
