Changing the SideBar after parsing an aspx page.

[whitehorse]

I am using a wizard control in my asp.net application. I use business
objects to determine if wizard steps are available/complete/incomplete. The
logic for determining a steps status can only be determined after page events
(wizard navigation ie Next/Previous).

This is what I have so far...

<SideBarTemplate>
<asp:DataList ID="SideBarList" runat="server">
<ItemTemplate>
<nobr>
<div style="vertical-align:middle" id="LinkDiv" runat="server"
visible='<%# (GetStepVisabillity(Container)).toString()%>'>
<%#GetStepLabelHTML(Container)%>
<asp:LinkButton ID="SideBarButton" runat="server"
CssClass='<%# (GetStepCSSClass(Container))%>' />
</div>
<div style="vertical-align:middle" id="TextDiv" runat="server"
visible='<%# (Not
GetStepVisabillity(Container)).toString()%>'>
<%#GetStepLabelHTML(Container)%>
<asp:Label ID="TextLabl" runat="server"
Text='<%# CType(Container.DataItem, WizardStep).Title %>'
CssClass='<%# (GetStepCSSClass(Container))%>'></asp:Label>
</div>
</nobr>
</ItemTemplate>
</asp:DataList>
</SideBarTemplate>

GetStepVisabillity, GetStepVisabillity and GetStepCSSClass are page level
methods.

The problem is that this template is parsed before even the page_load event.
The state of the steps is not known until after events are processed.

Is there a way to get around this?
Maybe by hooking into some kind of event when the Sidebar is rendered?
