vb.net wpf popup no focus -

i have several popups in wpf application, work fine.

however, last 1 not accepting focus or input in textboxes. , don't see why.

                    <label x:name="lblsearch" grid.row="0" grid.column="0" grid.columnspan="1" horizontalalignment="center" verticalalignment="top" margin="0,5" height="30" width="auto">search</label>                     <textbox name="txtsearch" grid.row="0" grid.column="1" grid.columnspan="1" horizontalalignment="center" verticalalignment="top" margin="0,5" height="30" width="200" isreadonly="false" isenabled="true"></textbox>                     <button name="btnsearch" grid.row="0" grid.column="2" style="{staticresource buttonsmall}" template="{dynamicresource blackbutton}" margin="5">search</button>                      <label x:name="lblreplace" grid.row="1" grid.column="0" grid.columnspan="1" horizontalalignment="center" verticalalignment="top" margin="0,5" height="30" width="auto">replace</label>                     <textbox name="txtreplace" grid.row="1" grid.column="1" grid.columnspan="1" horizontalalignment="center" verticalalignment="top" margin="0,5" height="30" width="200" isreadonly="false" isenabled="true"></textbox>                     <button name="btnreplace" grid.row="1" grid.column="2" style="{staticresource buttonsmall}" template="{dynamicresource blackbutton}" margin="5">replace</button>                      <button name="btnstopsearch"  grid.row="2" grid.column="3" style="{staticresource buttonsmall}" template="{dynamicresource blackbutton}" margin="5">done</button>                      <dockpanel grid.row="2" grid.column="0" grid.columnspan="2">                     </dockpanel>                 </local:gridex>             </dockpanel>         </border>     </border> </popup> 

i tried code force focus on no avail:

private searchwhere string = nothing private sub txttypeeditor_keydown(sender object, e forms.keyeventargs) handles txttypeeditor.keydown     if e.keycode = forms.keys.f andalso e.control andalso not e.alt andalso not e.shift         popupsearch.isopen = true         txtsearch.focus()         keyboard.focus(txtsearch)         searchwhere = "typeeditor"         e.handled = true     end if end sub  private sub popup1_opened(sender object, e eventargs) handles popupsearch.opened     txtsearch.focus()     keyboard.focus(txtsearch) end sub 

it appears txttypeeditor holds onto focus. idea how blur it?

i have workaround: if blur textbox focusing textbox popup accepts focus.

however if user clicks txttypeeditor textbox , clicks inputfield in popup, mouse focus switches popup, keyboard focus stays textbox.

this guess: maybe related txttypeeditor_keydown event stays somehow in txttypeeditor? give try keypress instead (if not affecting other part of code)
