Hi Nina,

You can solve this in a couple of different ways. I've got two suggestions.

If you show the Event items in a table, I can recommend the jQuery plugin tablesorter

But you're probably showing items in a list, and then I would make each option link to the same page with a query string describing which type and order of sorting the end-user is selecting, for example:

www.yoursite.com/events.aspx?sort=eventDate&order=desc

In the xslt you will have to ask for content in the query string and pass it on to the sorting method.

<xsl:variable name="SortOrder">
<xsl:choose>
<xsl:when test="umbraco.library:RequestQueryString('order') = 'desc'">
<xsl:value-of select="descending" />  
</xsl:when>
<xsl:otherwise>
<!-- the standard way of ordering -->
<xsl:value-of select="ascending" />  
</xsl:otherwise>
</xsl:choose>
</xsl:variable>

<xsl:variable name="SortBy">
<xsl:choose>
<xsl:when test="umbraco.library:RequestQueryString('sort') = 'cat'">
<xsl:value-of select="cat" />  
</xsl:when>
<xsl:when test="umbraco.library:RequestQueryString('sort') = 'price'">
<xsl:value-of select="price" />  
</xsl:when>
<xsl:otherwise>
<!-- the standard way of sorting -->
<xsl:value-of select="eventDate" />  
</xsl:otherwise>
</xsl:choose>
</xsl:variable>

<!-- We need to set data-type to number or text depending on what sortby equals -->
<xsl:variable name="DataType">  
    <xsl:choose>  
        <xsl:when test="$SortBy='price'">  
            <xsl:value-of select="'number'" />  
        </xsl:when>  
        <xsl:otherwise>  
            <xsl:value-of select="'text'" />  
        </xsl:otherwise>  
    </xsl:choose>  
</xsl:variable>

<ul>
<xsl:for-each select="YourData">
<xsl:sort select="@*[name() = $SortBy]" order="{$SortOrder}" data-type="{$DataType}"/>
<li>
....
</li>
</xsl:for-each>
</ul>

Parts of the code is taken from CWS ListNewsEvents and adjusted to your needs. I haven't actually run the xslt to see whether it works, but if not please get back to me.

I hope this is what you're looking for.

Cheers,

hy and first: thank you for your prompt answer! it makes me happy to see that this forum seems to be an active forum and that i get help :) i think the tablesorter isn´t really what i´m looking for because i have another structure: i have 3 columns with news or eventitems and one of this items consists of:

event/newsdate - category (health, lifestyle, finance ...)
heading - price
article content .....

so your second option should meet my requirements, but (probably a stupid question but i´m really new to this stuff and don´t really know much until now. hope it´s getting better!) how and where can i build these querystrings? do i need an extra xslt file for this or do i have to change the url name of the site?

thank you for your help! - nina
