the problem checkbox on dropdown. tried checkbox.horizontalalignment = windows.horizontalalignment.right dropdown takes cell width.

all want dropdown @ left , checkbox @ right can't figure how it

thank you

here final version

 private sub replaceuielementingrid(byval newuielement uielement, byval uielementtoreplace uielement, byval gridtoaddnewuielement grid)     if gridtoaddnewuielement.children.contains(uielementtoreplace)         dim panel wrappanel = new wrappanel         grid.setrow(panel, grid.getrow(uielementtoreplace))         grid.setcolumn(panel, grid.getcolumn(uielementtoreplace))         dim pos integer = gridtoaddnewuielement.children.indexof(uielementtoreplace)         gridtoaddnewuielement.children.removeat(pos)         panel.children.add(newuielement)          try             dim label label = directcast(uielementtoreplace, label)             if (label.name.contains("activity"))                 dim checkbox checkbox                 checkbox = new checkbox()                 checkbox.content = "direction"                  'checkbox.horizontalalignment = windows.horizontalalignment.right                 'dim uicheckbox uielement = directcast(checkbox, uielement)                 panel.children.add(checkbox)                 addhandler checkbox.click, addressof filtrerdropdownactiviteevent             end if         catch ex exception          end try         gridtoaddnewuielement.children.add(panel)     end if end sub

wrap grid or panel type around dropdown , checkbox. format it, , replace label grid (or whatever).

edit:

just more specific, end this:

<grid>     <combobox />     <checkbox /> </grid>

but should go this:

 <grid>         <grid>             <grid.columndefinitions>                 <columndefinition width=".50" />                 <columndefinition width=".50" />             </grid.columndefinitions>             <combobox grid.column="0"  />             <checkbox grid.column="1"  />         </grid>  </grid>
