Widget display in editor

Is there a way to format the display of a widget in the CMS editor? I have a widget that doesn't really have any static HTML in it (code below). So, when a user adds the widget to the page, it doesn't look like there's anything there.

I did add the "kenticoWebPartMessage" literal with text "[MY WIDGET NAME]". I toggle its display based on PortalContext.ViewMode, but that seems a little clunky. Is there a better way to give the widget a visual presence to the content editor?

<asp:Literal runat="server" ID="kenticoWebPartMessage" Visible="false" />

<asp:Repeater runat="server" ID="Legislators" OnItemDataBound="Legislators_ItemDataBound">
    <ItemTemplate>
        <p>
            <strong><asp:Literal runat="server" ID="LegislatorTypeAndDistrict" />:
                <asp:Literal ID="LegName" runat="server" />
            </strong>


            <asp:Literal ID="LinkLabel" runat="server" />
            <asp:HyperLink runat="server" ID="LegislatorLink" />

            <asp:Literal ID="EmailLabel" runat="server" />
            <asp:HyperLink runat="server" ID="LegislatorEmail" />
            </p>
    </ItemTemplate>
</asp:Repeater>
