NetAdvantage UltraWebGrid version 8.2.20082.2160

We have grids that display hyperlinks.  They are created in two different ways, depending on the situation.  The first creates the hyperlink as a button and creates source code that looks like this:

<C iDV="CRXU4508410">
    <![CDATA[<input type="button" style="width:100%;height:100%;" value="CRXU4508410"
             onclick="igtbl_colButtonClick(event,\'uwgResults\',null, igtbl_srcElement(event));" class="ig_7fddad5d_rcb1412" tabindex="-1" />]]>
</C>

The second creates an a href tag and looks like this:

<C>
    <![CDATA[<a href="BLOCKED SCRIPTvoid(0);" onClick="return CreateComment(\'792H000014NB0\',\'CRXU4508410\');">Add Comment</a>]]>
</C>

The columns created the first way are able to be grouped.  The columns created the second way are not.  You can drag the column header to the grouping bar, but they are still listed individually.

I notice two differences (other than the fact that one is a button and one is an href).  The first one has a value="..." and the first also has a property in the C tag.  I tried adding a value="..." to the second version, but that still didn't work.  It seems to me that the grouping is enabled by the iDV="..." property in the C tag. Is there any way to get the grouping to work on an a href tag?
