wpf - Positioning UIElement in Custom Control -


i developing custom control, there textbox , button placed inside grid.

the thing when set custom property usercontrol - left : button should displayed before textbox, , right button should displayed on right side of text box.

since, defining both elements in grid - not able position per requirements.

if have use grid, can make grid have 3 columns , switch textbox grid.column based on custom property.

<grid>   <grid.columndefinitions>     <columndefinition width="auto" />     <columndefinition width="*" />     <columndefinition width="auto" />   </grid.columndefinitions>   <button grid.column="1"           content="some text" />   <textbox text="test">     <textbox.style>       <style targettype="{x:type textbox}">         <setter property="grid.column"                 value="0" />         <style.triggers>           <datatrigger binding="{binding relativesource={relativesource findancestor,                                                                         ancestortype={x:type usercontrol}},                                           path=left}"                         value="true">             <setter property="grid.column"                     value="2" />           </datatrigger>         </style.triggers>       </style>     </textbox.style>   </textbox> </grid>

you can switch {x:type usercontrol} in datatrigger {x:type customusercontrol}
