Custom gridview - bind using non-static function

Question

I am currently attempting to implement a custom gridview interface to display data from an ObjectDataSource frontend to ASP.net membership. The asp.net code for the gridview is

  <asp:GridView
   id="grdUsers"
   HeaderStyle-cssclass="grid_header"
   RowStyle-cssclass="row"
   AlternatingRowStyle-cssclass="alternating"
   OnRowUpdating="grdUsers_RowUpdating"
   OnRowDeleting="grdUsers_RowDeleting"
   OnRowCancelingEdit="grdUsers_cancelEdit"
   datasourceid="srcUsers"
   autogeneratecolumns="false"
   allowsorting="true"
   AllowPaging="true"
   EmptyDataText="No users..."
   pagesize="9"
   runat="server">
   <Columns>
    <asp:CommandField
     HeaderText="Ops"
     ButtonType="Image"
     ShowEditButton="true"
     EditText="E"
     UpdateText="U"
     ShowCancelButton="true"
     CancelText="X"
     ShowDeleteButton="true"
     DeleteText="D" />
    <asp:BoundField
     ReadOnly="true"
     DataField="UserName"
     HeaderText="UserName" />
    <asp:BoundField
     DataField="Email"
     HeaderText="Contact Email" />
    <asp:TemplateField
     HeaderText="Role">
     <ItemTemplate>
     <asp:Label 
      ID="lblRole"
      text="<%# namespace.Admin.getRoleOfUser( ) %>" 
      runat="server" />
     </ItemTemplate>
     </asp:TemplateField>
    <asp:CheckBoxField
     DataField="IsApproved"
     HeaderText="User is Approved" />
    <asp:TemplateField 
     HeaderText="UserLocked">
     <ItemTemplate>
     <asp:CheckBox 
      id="grdUsers_lockCheckBox"
      Checked='<%# Eval("IsLockedOut") %>'
      Enabled="false"
      runat="server" />
     </ItemTemplate>
     <EditItemTemplate>
     <asp:Button 
      id="grdUsers_unlockUser"
      OnClick="grdUsers_unlockUser"
      Text="Unlock"
      runat="server" />
     <asp:HyperLink 
      id="grdUsers_lockInfo"
      text="?"
      onclick='popup("lock_info.html")'
      runat="server" /> 
     </EditItemTemplate>
    </asp:TemplateField>
   </Columns>
   </asp:GridView>

My code is currently dying because the function get roleOfUser() is a public function. Preferably I would like to pass a string of the UserName (pulled from the second cell of the GridView) to this function but that I am not sure of, as well as how to call this non-static function as I don't know how to instantiate it from the asp.net code.

 public string getRoleOfUser( )
 {
  GridView users = (GridView)admin.FindControlRecursive(Page, "grdUsers");
  Int32 i = users.EditIndex;

  GridViewRow userRow = users.Rows[i];

  return userRow.Cells[1].Text;
 }

 private Control FindControlRecursive(Control root, string id)
 {
  if (root.ID == id)
  {
   return root;
  }

  foreach (Control c in root.Controls)
  {
   Control t = FindControlRecursive(c, id);
   if (t != null)
   {
    return t;
   }
  }

  return null;
 }

It should just be:

<% getRoleOfUser( ) %>

Assuming its a member function of the page your GridView is on.
