Only display div in template when no querystring present
Hi,

I have a website homepage which contains a div containing general content and a list of news items which are paginated. I want to display the general content div only when the user is on the first page i.e. when there's no querystring variable or when the querystring is 'page=1'.

Is it possible to insert some inline C# to do this, or is there a better way?

The code I have in the template is currently like this:
```
<asp:content ContentPlaceHolderId="childContent" runat="server">
   <div class="general-content">
       General content
   </div>
  <umbraco:Macro Alias="paginatedArticles" runat="server"></umbraco:Macro>
</asp:content>
```
Thanks for any pointers...

Hi Dan,

<asp:content ContentPlaceHolderId="childContent" runat="server">
<% if (!(string.IsNullOrEmpty(Request.QueryString["page"]))) { %>
        <div class="general-content">
                General content
        </div>
<% } %>
        <umbraco:Macro Alias="paginatedArticles" runat="server"></umbraco:Macro>
</asp:content>

Hope this helps.

Regards,

/Dirk

In XSLT it is:

<xsl:variable name="year" select="umbraco.library:RequestQueryString('page')"/>
<xsl:if test="$year != ''">
  <div...

Thanks Dirk & Thomas.

Dirk, your solution works when there's no variable, but I also need it to work when the querystring value is 1. I've tried this, but just get an error:
```
<% if ((string.IsNullOrEmpty(Request.QueryString["page"])) || (Request.QueryString["page"].ToString() != '1')){ %>
```
The error is something to do with the data types of the requested string and the comparitor:

"CS0019: Operator '!=' cannot be applied to operands of type 'string' and 'char'"

Can you see why this is erroring?

'1' is a character not an string so you have to cast:
```
if ((string.IsNullOrEmpty(Request.QueryString["page"])) || (Request.QueryString["page"] != '1'.ToString()))
```

btw: the
```
Request.QueryString["page"]
```
so you dont need to cast this ;-)

Or just use "1" instead of '1'.ToString()
