Checking if item is empty in master template

Version: Umbraco v 4.0.2.1

I need to check if the editor has put any content in this field <umbraco:Item field="umbracoDidYouKnow" runat="server"></umbraco:Item> which is a simple textstring. What is the syntax for doing this?

I am new to Umbraco and .net in general so i haven't been able to find the right syntax despite vigorous googling.

To clarify:

if umbracoDidYouKnow = "" then

<div id="content">

else

<div id="contentWide">

end if

Id use an xslt macro for this. if the umbracoDidYouKnow is on the current page, this should work:

<xsl:choose>
   <xsl:when test="string($currentPage/data [@alias='umbracoDidYouKnow']) != ''">
      <div id="contentWide">
          <xsl:value-of select="$currentPage/data [@alias='umbracoDidYouKnow']" />  
      </div>
  </xsl:when>
 <xsl:otherwise>
     <div id="content">
          <!-- Etc -->
        </div>
  </xsl:otherwise>
</xsl:choose>

oh, should mention: If you're brand new this may help -> http://umbraco.org/documentation/books/xslt-basics/what-is-xslt

Post back if you continue to have difficulties, and someone should be able to help you out.
