DotNetNuke No Search Results Message

I’ve finally deployed the DotNetNuke site I’ve been working on. After deployment is when the most obvious things pop up.

For instance, in DotNetNuke when you search for something in the site it will return a list of links to what it finds. What it won’t do is display something friendly like “No Search Results Found” if it doesn’t find anything. Dumb and not very user friendly.

I did find what I thought would be the solution at ecktwo, but it didn’t work in Firefox due to the

document.getElementById("search").innerHTML

which doesn’t work in Firefox within a table, which is what the Search Results are generated using the ASP.NET grid view. So, I thought I’d take a stab at building something that worked for both IE and Firefox.

Make a copy of your admin\Search\SearchResults.ascx file and then open the file in notepad. Apply the following code that I’ve highlighted in red:

<%@ Control Language=”vb” AutoEventWireup=”false” Explicit=”True” Inherits=”DotNetNuke.Modules.SearchResults.SearchResults” CodeFile=”SearchResults.ascx.vb” %>

<asp:Datagrid id=”dgResults” runat=”server” AutoGenerateColumns=”False” AllowPaging=”True” BorderStyle=”None”
PagerStyle-CssClass=”NormalBold” ShowHeader=”False” CellPadding=”4″ GridLines=”None”>
<Columns>
<asp:TemplateColumn>
<ItemTemplate>
<asp:Label id=lblNo runat=”server” Text='<%# DataBinder.Eval(Container, “ItemIndex”) + 1 %>’ CssClass=”SubHead”>
</asp:Label>
</ItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn>
<ItemTemplate>
<asp:HyperLink id=”lnkTitle” runat=”server” Name=”result” CssClass=”SubHead” NavigateUrl='<%# FormatURL(DataBinder.Eval(Container.DataItem,”TabId”),
DataBinder.Eval(Container.DataItem,”Guid”)) %>’ Text='<%# DataBinder.Eval(Container.DataItem, “Title”) %>’>
</asp:HyperLink>&nbsp;-
<asp:Label id=”lblRelevance” runat=”server” CssClass=”Normal” Text='<%# FormatRelevance(DataBinder.Eval(Container.DataItem, “Relevance”)) %>’ >
</asp:Label><BR>
<asp:Label id=”lblSummary” runat=”server” CssClass=”Normal” Text='<%# DataBinder.Eval(Container.DataItem, “Description”) + “<br>” %>’ Visible=”<%# ShowDescription() %>”>
</asp:Label>
<asp:HyperLink id=”lnkLink” runat=”server” CssClass=”CommandButton” NavigateUrl='<%# FormatURL(DataBinder.Eval(Container.DataItem,”TabId”),
DataBinder.Eval(Container.DataItem,”Guid”)) %>’ Text='<%# FormatURL(DataBinder.Eval(Container.DataItem,”TabId”),
DataBinder.Eval(Container.DataItem,”Guid”)) %>’>
</asp:HyperLink>&nbsp;-
<asp:Label id=”lblPubDate” runat=”server” CssClass=”Normal” Text='<%# FormatDate(DataBinder.Eval(Container.DataItem, “PubDate”)) %>’>
</asp:Label>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
<PagerStyle CssClass=”NormalBold” Mode=”NumericPages”></PagerStyle>
</asp:Datagrid>

<div id=”NoResults”>
<h3 class=”red” style=”text-align:center”>No Search Results Found</h3>
</div>
<script language =”Javascript”>
var search;
search = document.getElementsByName(“result”);

if (search.length == 0) {
document.getElementById(“NoResults”).style.display=’block';
}
else {
document.getElementById(“NoResults”).style.display=’none';
}
</script>

Be sure to add the Name=”result” snippet to the asp:Hyperlink in the code above. It’s easy to miss.

Save that and you should now have a spiffy new message displayed when no results are found. Use whatever CSS you want to style the message.

  1. I didn’t find that the code worked exactly correct. With DNN 4.8.2 the message is displayed always, with or without finding the content. The message is at the bottom each page of results, with results present or not its there. I’m sure I pasted it correctly and got the top snippet in, too. Not sure if that what you intended.

  2. el codigo esta perfecto mano, solo tuve que arreglar las comillas y me funciono a la perfeccion, gracias

  3. I also can’t understand why this isn’t included in the core code. Nonetheless, your fix is quick and painless to include so thank you…

  4. @Andrew: Be sure to reformat the quote and double quote chars when you copy/paste from the web. It should work properly after that.

  5. Thanks, man. Your little tip saved me a lot of time! It works great.

    My only concern has to do when I upgrade my current DNN installation. I’m afraid that the changes I made to the admin/SearchResults.ascx will be lost.

    By the way, another way to have this done via server-side code is to remove the code-behind directives and use embedded code in a script tag with runat=”server” in it. I tried this technique in a client’s website where I lost all source code. I haven’t tried doing this with the DNN searchresults.ascx file, though, but I know it is possible to do so and use modify the code so a GridView or ListView with an EmptyDataTemplate can be used.
