Custom ImageButtons in a GridView

[Gileno]

Hi!

I Have a gridView with a TemplateField, with this code:

<asp:TemplateField>
  <ItemTemplate>
    <img alt="Editar" src="./imagens/icon_editar.gif" />
    <%# getActionStatus((int)Eval("idacesso"), (bool)Eval("bloqueado")) %>
  </ItemTemplate>
  <HeaderStyle Width="40px" />
</asp:TemplateField>
 

Here is my getActionStatus:

    protected string getActionStatus(int idAcesso, bool bloqueado)
    {
        if (bloqueado == false)
        {
            return "<img alt=\"Bloquear\" src=\"../admin/imagens/icon_bloquear.gif\" />";
        }
        else
        {
            return "<img alt=\"Ativar\" src=\"../admin/imagens/icon_ativar.gif\" />";
 
        }
    }
 

The Result is:

I need transform this images in asp:ImageButtons, but this approuch don't works when i return ASP.NET Controls like:

<asp:ImageButton ID="ImageButton1" CssClass="alignBtnImage" Runat="server" ImageUrl="./imagens/icon_bloquear.gif" OnClientClick="return confirm('Deseja realmente bloquear este acesso?');" ToolTip="Bloquear" CommandName="setStatus" />
 

Anyone can help me?
