cfgridcolumn with hyperlink

Hi,

this code works fine, the link from A Number field opens the new page. Instead of open the new page in a new window,  I want it to open in the pop up window, is there the way to do it? thx

<cfform name="myGrid">

    <cfgrid
       name="grdANo"
       format="HTML"
       title="Search Result"
       collapsible="false"
    selectMode=" Single"
    pagesize="#variables.row_per_page_default#"
    bindOnLoad="true" 
      stripeRowColor ="silver"
    stripeRows="yes"  width="600"
          appendkey="no"
         bind="cfc:cfc.searchA.searhANo({cfgridpage},{cfgridpagesize},
            {cfgridsortcolumn},{cfgridsortdirection},{aNo})">
        <cfgridcolumn name="id" header="id" display="no"/>
      <cfgridcolumn name="aNo" width="200" display="yes" headerbold="yes" header="A Number" href="index.cfm?action=editA" hrefkey="id" target="_blank" />
      
    </cfgrid>
</cfform>
