Hi, I have a template with a listsummary control. There will be times that the folder the control uses won't contain any content. How can I generate a message on the webpage when there is no content?--something like "No current new articles. Please check back". Thanks for any help! We're using 7.6.6. SP2.

mr
you can do this a couple of ways.
- XSLT. Are you using an XSLT with your list summary? If so you can add a few lines of code here to display this type of message.
- ASP Literal. In the code behind of your page you could inspect the EKItems property of the ListSummary, if its length is 0 then display the message using the literal.
If you're not using XSLT currently then go with #2.
Carl.

Thanks, Carl, for the reply! I am actually using an xslt. Can you tell me which xsl element would be used to generate the message? I've been learning xml/xslt as I go, and this one really has me stumped! I'd really appreciate any pointers you can give! Mary

It would be something similar to this, which checks if the first content is empty, then display message.
<xsl:if test="Collection/Content != ''">There is no content</xsl:if>
Think outside the box.

Rui, this seems like the perfect fix! But I'm still having some trouble. I tried using the following:
<xsl:template match="/">
<xsl:for-each select="Collection/Content">
<xsl:choose>
<xsl:when test="Collection/Content != ''">
There is no content
<xsl:when>
<xsl:otherwise>
<xsl: value-of... [other fields]
</xsl:otherwise>
</xsl:choose>
If I have content in the folder it's displaying correctly; however, if there is no content, I'm not seeing the message. Am I applying this correctly?

Hey Mary,
you have your test inside a for each Content item block, if there are no content blocks then this code will not be executed. Move your test outside the for each loop.
Hope this helps.

Here is the working XSLT
<xsl:template match="/">
<xsl:if test="count(Collection/Content) < 1">
There is no content
</xsl:if>
<xsl:for-each select="Collection/Content">
<li>
<xsl:value-of select="Title"></xsl:value-of>
</li>
</xsl:for-each>
</xsl:template>
Think outside the box.

This works beautifully, and is exactly what I needed! Thank you, Carl and Rui, for the explanation and for helping me to understand how to apply it! Mary
