the class contains list of string variables of name somelist. have binded 3rd column. need attach combobox in header of column 3. code not give me want.

can ?

your problem seems add stackpanel item itemscontrol instead of using in datatemplate.

instead of

<itemscontrol itemsource="{binding somelist}">     <stackpanel orientation="horizontal">         <textblock text="sometopic"/>         <combobox itemsource="{binding }"/>     </stackpanel> </itemscontrol> 

it should this:

<itemscontrol itemsource="{binding somelist}">     <itemscontrol.itemtemplate>         <datatemplate>             <stackpanel orientation="horizontal">                 <textblock text="sometopic"/>                 <combobox itemsource="{binding }"/>             </stackpanel>         </datatemplate>     </itemscontrol.itemtemplate> </itemscontrol>
