User Control Property Persistence - How do I get my property value to stay/come back to me?

I have a user control that's rendered in a data bound List View, for example:

<asp:ListView ID="ListBuildings" DataSourceId="ListDataSource" runat="server">

<ItemTemplate>

    <custom:Rater ID="Rater" BuildingId='<%# Eval("BuildingId")%>' runat="server" />

</ItemTemplate>

</asp:ListView> 

I set a custom property on my user control called BuildingId, but on post backs I'm not finding the BuildingId property set to what I set it to in the through the list view's databinding.

I can see that on postbacks the listview isn't getting re-binded, it's values are being persisted through viewstate. Why isn't my user control's BuildingId property value being persisted though? 

Any input on how I might be able to set a custom property on a user control from within an item template for a data bound control, and then retrieve that value on further postbacks from events in the aformentioned user control would be really appreciated.

Thanks,

In the user control inseta of keeping the value in a varibale keep it in the viewstate and u will find the value after postback

public int BuildingId 

{

get{ return convert.ToInt32(viewstate["BuildingId"]);}

set{viewstate["BuildingId"] = value;}

}
