Display the Page.User.Identity.Name in the datagrid hyperlink column

Question

Hi,

I am using asp.net, C# and sql server

I have a gridview control which looks like the following

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">

  <Columns>

     <asp:HyperLinkField DataTextField="Name" DataNavigateUrlFields=""          

DataNavigateUrlFormatString="http://www.anrdoezrs.net/click-1850716-10387413?sid={0}"/>

     <asp:BoundField DataField="Decsription"/>

  </Columns>

</asp:GridView>

In the DataNavigateUrlFormatString="http://www.anrdoezrs.net/click-1850716-10387413?sid={0}

i want to replace the {0} with the logged in user's identity which is Page.User.Identity.Name.

How should i do it should i do it in the DataNavigateUrlFields property or in the code behind pages.

I tried creating a method in the code behind file as follows to get the identity and displaying it

public string GetMemberID()
    {
        return Page.User.Identity.Name.ToString();
    }

and tried calling it in the datagrid hyperlink column as follows

<asp:HyperLinkField DataTextField="Name"  DataNavigateUrlFormatString='<%#

string.Format("http://www.anrdoezrs.net/click-1850716-10387413?sid={0}", GetMemberID()) %>'/>

but got an error message as follows :

Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.HyperLinkField does not have a DataBinding event.

How should i go about it. Please help.

Thanx in advance.
