Many times you might have been asked to change the SharePoint Library views with new columns, calculated columns etc. This technique explains how you can group the items based on a column and provide the item count under that group in the header.
So essentially something like this:
+ Project: XYZ (15 items)
+ Project: ABC (25 Items)
Its pretty simple to achieve the grouping but a small trick to display the item counts.
First open your site in SharePoint Designer and go to the Page view (mostly in the /POages directory)
Then right click on the ListView and convert to DataView.
Go to DataView Properties-->Groupby-->Collapse header
Then in the name column enter the following:
<xsl:value-of select="$fieldvalue" > : <xsl:value-of select="count($nodeset[*[name()=$fieldname]=$fieldvalue or ($fieldtype!='isodatetime' and @*[name()=$fieldname]=$fieldvalue) or ($fieldtype='isodatetime' and ddwrt:GenDisplayName(string(@*[name()=$fieldname]))=$fieldvalue) or (not(*[name()=$fieldname] or @*[name()=$fieldname]) and $fieldvalue = ' ')]/@ID)" />
--------- BANG !!! There you go... as easy as it gets
