c# - WPF Datgrid binding text with tooltip to to different properties -

i want show body of email in tooltip , shortened version in column

<datagridtextcolumn binding="{binding body}"         header="{x:static t:resource.gridbody}" width="100">     <datagridtextcolumn.elementstyle>         <style targettype="textblock">             <setter property="texttrimming" value="characterellipsis"/>             <setter property="tooltip"                     value="{binding text, relativesource= {relativesource self}}" />         </style>     </datagridtextcolumn.elementstyle> </datagridtextcolumn> 

i ellipsis on each character, have property has first 3 lines , bind column , body tooltip

instead of using style used datagridtemplatecolumn instead of datagridtextcolumn

<datagridtemplatecolumn  header="{x:static t:resource.gridbody}" width="150">  <datagridtemplatecolumn.celltemplate>       <datatemplate>         <textblock text="{binding shortbody}" texttrimming="characterellipsis" tooltip="{binding body}" />        </datatemplate>    </datagridtemplatecolumn.celltemplate>  </datagridtemplatecolumn>
