<grid x:name="layoutroot" background="white">     <sdk:datagrid  autogeneratecolumns="false" >         <sdk:datagrid.columns>             <sdk:datagridtextcolumn  visibility="collapsed">             </sdk:datagridtextcolumn>         </sdk:datagrid.columns>         <sdk:datagrid.rowdetailstemplate>             <datatemplate>                 <stackpanel>                     <sdk:datagrid  width="auto" flowdirection="righttoleft">                         <sdk:datagrid.columns>                             <sdk:datagridtemplatecolumn >                                 <sdk:datagridtemplatecolumn.celltemplate>                                     <datatemplate>                                         <combobox name="cbaction" selectionchanged="cbaction_selectionchanged" />                                     </datatemplate>                                 </sdk:datagridtemplatecolumn.celltemplate>                             </sdk:datagridtemplatecolumn>                             <sdk:datagridtemplatecolumn >                                 <sdk:datagridtemplatecolumn.celltemplate>                                     <datatemplate >                                         <stackpanel orientation="horizontal" verticalalignment="center">                                             <checkbox name="cbchaluka" width="30" verticalalignment="center"  horizontalalignment="center"  isenabled="false" ischecked="{binding _logi_got,mode=twoway}" flowdirection="lefttoright">                                             </checkbox>                                         </stackpanel>                                     </datatemplate>                                 </sdk:datagridtemplatecolumn.celltemplate>                             </sdk:datagridtemplatecolumn>                         </sdk:datagrid.columns>                     </sdk:datagrid>                 </stackpanel>             </datatemplate>         </sdk:datagrid.rowdetailstemplate>     </sdk:datagrid> </grid>

this important!!!!

small example...

private checkbox cbchaluka = null;  private void datagridname_loadingrowdetails(object sender, datagridrowdetailseventargs e) {     cbchaluka = e.detailselement.findname("cbchaluka"); }

then on selectionchange event on other control can reference cbchaluka.
