Is there any way in SharePoint to make a Content Query Web Part hidden if no content returns?

Question

Right now I was trying to configure a content query web part so that if nothing returned from the query, the web part was hidden (or not returning at all). Title and everything included. Is there an easy way of accomplishing this? Was looking at writing some JavaScript/Jquery to accomplish this, but I'm positive there is something easier.

Answer 1

When no results found the template OuterTemplate.Empty is rendered for CQWP by default:

  <xsl:template name="OuterTemplate.Empty">
        <xsl:param name="EditMode" />
            <xsl:if test="$EditMode = 'True' and string-length($cbq_errortext) = 0">
                <div class="wp-content description">
                    <xsl:value-of disable-output-escaping="yes" select="$cbq_viewemptytext" />
                </div>
            </xsl:if>
    </xsl:template>

Solution

• JavaScript code for hiding web part is placed in that template.
• To identify CQWP on the client side is used XSL parameter WebPartId

Modified template OuterTemplate.Empty for hiding web part (jQuery):

<xsl:template name="OuterTemplate.Empty">
        <xsl:param name="EditMode" />
            <xsl:if test="$EditMode = 'True' and string-length($cbq_errortext) = 0">
                <div class="wp-content description">
                    <xsl:value-of disable-output-escaping="yes" select="$cbq_viewemptytext" />
                </div>
            </xsl:if>
            <script type="text/javascript">
            var webPartId = '<xsl:value-of select="$WebPartId" disable-output-escaping="yes"/>';
            var webPartContainer = $("div[webPartId='" + webPartId + "']").closest('table');
            webPartContainer.hide();
            </script>
    </xsl:template>

Yes you can do it with JavaScript, but you can do it with pure XSLT manipulation too.

When no content returns, if you don't want to show even the title of the webpart, then you can set the ChromeType property of the webpart to "None". This will permanently hide the title of the webpart (even if content is returned).

Now in your XSLT, you can generate the Title of the WebPart as well as render the items only if content is returned.

Yes, you can do it with jQuery too. My approach is: add this to your global JS file.

$('.cbq-layout-main:empty').closest('.s4-wpcell-plain').hide();

It will select any Content Query Web Part that has nothing inside it and hide the Web Part Cell related to it.
