c# - Autosize to only some controls -

i'm working on wpf gui, , want window auto-size content, not everything: have various buttons & other controls, , want autosize width that. if add long item list box, want window stay same size.

example code:

<window x:class="quickiewpf.mainwindow"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         title="mainwindow" sizetocontent="widthandheight" resizemode="canminimize">     <grid>         <grid.rowdefinitions>             <rowdefinition/>             <rowdefinition/>         </grid.rowdefinitions>         <stackpanel orientation="horizontal">             <button width="100" content="foo" click="button_click"/>             <button width="100" content="bar" click="button_click"/>             <button width="100" content="baz" click="button_click"/>         </stackpanel>         <listbox grid.row="1" name="thelist" height="100"/>     </grid> </window>  public partial class mainwindow : window {     public mainwindow()     {         initializecomponent();     }      private void button_click(object sender, routedeventargs e)     {         string str = "this long text item wider " +             "three buttons. want horizontal scrollbar on listbox, not wider " +             "window. want window size buttons, not listbox.";         this.thelist.items.add(str);     } } 

initially, window sized buttons:

after adding long item list box, this:

but i'd rather this:

(i did last screenshot setting maxwidth on list box, isn't solution full application: in full application, it's more 3 buttons; it's buttons, icons, textboxes, labels, etc, , want window autosize whole mess, not listbox @ bottom.)

you can bind width of content not want autosize actual width of content do, example:

<grid>     <grid.rowdefinitions>         <rowdefinition />         <rowdefinition />     </grid.rowdefinitions>     <stackpanel orientation="horizontal" x:name="panel">         <button width="100"                 content="foo"                 click="button_click" />         <button width="100"                 content="bar"                 click="button_click" />         <button width="100"                 content="baz"                 click="button_click" />     </stackpanel>     <listbox grid.row="1"              name="thelist"              height="100" width="{binding elementname=panel, path=actualwidth}" /> </grid> 

here bound width of listbox actual width of panel buttons, in case achieves want.
