总结：SharePoint Designer 2010 DVWP (3) -- DataFormWebPart -- Sort and Group

选中DataFormWebPart，然后点击Ribbon上的“Sort & Group”，选择要排序或分组的字段，再设置一下显示样式，最后根据需求自己调整XSLT就可以了。

统计当前分组：

<xsl:template name="dvt_1.groupheader0">

              ...

              <xsl:param name="nodeset" />

    ...

   

    <xsl:value-of select="count($nodeset/@LinkTitle)" />

 

</xsl:template>

 

 

统计所有：

<xsl:template name="dvt_1">

 <xsl:variable name="dvt_StyleName">Table</xsl:variable>

 <xsl:variable name="Rows" select="/dsQueryResponse/Rows/Row"/>

 ...

 

   Total: <xsl:value-of select=" count($Rows/@Title)"/>

 

</xsl:template>
