How to add NickName column to customer list in admin area?

[Drebbin]

Hi all,

I need help with adding a NickName column to the customer list in the admin area.

So far I've added NickName to admin/controls/customergrid.ascx line 99

...atingItemStyle CssClass="config_alternating_item" />
<Columns>

<telerik:GridTemplateColumn HeaderText="Account Number" UniqueName="NickName">
<ItemTemplate>
<asp:Literal ID="ltNickName" runat="server" />
</ItemTemplate>
</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="IDColumn" HeaderText="ID" SortExpression="CustomerID">
<ItemTemplate>
<asp:LinkButton ID="lbtnID" runat="...

...and to admin/controls/customergrid.ascx.cs liine 328

...r gc = gi.DataItem as GridCustomer;

if (gc != null)
{
// account number (nick name) column
Literal ltNickName = gi.FindControl<Literal>("ltNickName");
ltNickName.Text = gc.BillingAddress.NickName;

// Customer ID column
LinkButton lbtnID = gi.FindControl<LinkButton>("lbtnID");
lbtnID.Text = gc....

Current code adds a column, but no NickName values display in it. From what I can make out, it's this little bugga that's causing all the problems:
ltNickName.Text = gc.BillingAddress.NickName; Probably because I'm guessing it.

Any help appreciated.
