Maintaining my own DataSource

[mbde]

I am in the midst of creating a re-usable composite control that just has a predefined grid on it, and a couple of text boxes to display customer information

I create a public datasource

public Customer DataSource
{
get{
object o = ViewState["DataSource"];
return (o == null)? null : (Customer)o;
}
set { ViewState["DataSource"]=value; }
}

and I override DataBind to do the custom mappings of the Cutomer object to each appropriate item

Customer is may up of various string variables and a List<Accounts> objects.

but when I put the statement
<cc:CustomerGrid Id="CustomerGrid" runat="server" DataSource='<% Eval("Customer") %>'>

The Databind runs before the assignment of the Datasoure, which I get because of the Eval statement.

I have looked into inheriting from DataboundControl. The one part that confuses me is the retrievedData parameter because my custom data does not adhere to IEnumerable.

Here is actual Code

<asp:CompleteGridView ID="AffiliationGrid" runat="server" 
    AutoGenerateColumns="False" SkinID="Common">
    <DetailTemplate>
        <cc:CustomerGrid ID="CustomerGrid1" runat="server" DataSource='<%# Eval("Customer") %>'/>
    </DetailTemplate>

So there is a list of Customer to an affiliation.

Thoughts on how to get the DataSource assigned before Databind Fires.

Figured it out

I was calling base.Databind on the control after trying to retreive the value by alling

base.DataBind();
CustomerGrid.DataSource = DataSource;
CustomerDatabind();

That worked.
