wpf - Grid row height ratio based on content -

-

i have grid 2 rows. in each row there listview. in first row there 100 items , in second row there 500 items. not fit on screen, have scrollbars shown @ each listview (no problem) , row heights should in ratio of heights of listviews. 1* , 5* don't know in advance how big these listboxes be.

note: each item may have different size, use actual listbox height instead of items count

<grid>     <grid.rowdefinitions>         <rowdefinition /> <!-- keep ratio of rows based on listbox heights -->         <rowdefinition />     </grid.rowdefinitions>     <listbox grid.row="0">         <!-- 100 items -->     </listbox>     <listbox grid.row="1">         <!-- 500 items -->     </listbox> </grid>

any ideas?

 <grid>     <grid.rowdefinitions>         <rowdefinition height="{binding height,elementname=listbox1}"/>         <!-- keep ratio of rows based on listbox heights -->         <rowdefinition height="{binding height,elementname=listbox2}"/>     </grid.rowdefinitions>     <listbox grid.row="0" x:name="listbox1">         <!-- 100 items -->     </listbox>     <listbox grid.row="1" x:name="listbox2">         <!-- 500 items -->     </listbox> </grid>

if have more complex scenarios, can use converter.
