xaml - WPF:stretch to parent loop -

in wpf application trying connect sizes app size. main grid stretches main window, canvas - main grid etc. not work. example, scrollviewer inside of canvas, stretches main grid. solution? simple code example:

<window height="400" width="200" ...>  <grid horizontalalignment="stretch" verticalalignment="stretch">     <grid.rowdefinitions>         <rowdefinition height="*"/>     </grid.rowdefinitions>     <grid.columndefinitions>         <columndefinition width="*"/>     </grid.columndefinitions>     <canvas grid.row="0" grid.column="0"  horizontalalignment="stretch" verticalalignment="stretch">         <scrollviewer   horizontalalignment="stretch" verticalalignment="stretch">          </scrollviewer>     </canvas>   </grid> </window> 

just remove canvas , work.

basically, canvas has infinite size default, in canvas cannot aligned, unless specify size maually.

<window height="400" width="200" ...>   <grid>     <scrollviewer>       </scrollviewer>   </grid> </window> 

note, dont have specify grid's column , row definitions, if there's single cell. works default. also, horizontal , vertical alignment hav value "stretch" default, not have specified explicitelly well.

since there nothing scrollviewer inside grid, remove grid well:

<window height="400" width="200" ...>   <scrollviewer>                 </scrollviewer> </window>
