c# - Object not Disappearing with Opacity -


i have wpf program shows web browser control. web browser control in overlay show in wpf. start off wpf program width set 0 , opacity set 0 , seems work okay (other thin straight line disappears when move form). there button when pressed sets overlay visible , width 1000:

wb_docpanel.visibility = system.windows.visibility.visible; wb_docpanel.opacity = 1d; wbo.visibility = system.windows.visibility.visible; wbo.width = 1000;

this shows web browser object. have button exact opposite, however, when pressed still leaves box web browser was. ideas how rid of it?

wb_docpanel.visibility = system.windows.visibility.collapsed; wb_docpanel.opacity = 0d; wbo.visibility = system.windows.visibility.collapsed; wbo.width = 0;

update

<dockpanel grid.row="1" name="wb_docpanel" visibility="collapsed" opacity="0" >   <border dockpanel.dock="top" margin="30 10 30 20" name="_webbrowserplacementtarget" /> </dockpanel>

is how doc panel generated. on main window opening following code present:

webbrowser wb = new webbrowser(); wbo = new wpf.webbrowseroverlay.webbrowseroverlay(_webbrowserplacementtarget); wb = wbo.webbrowser;
