i have datagrid used in 2 different views. in each case, have last column resize it's width if user resizes host control/view.

how that?

cheers,

... canuserresizecolumns="true" >

    <datagrid.columns>         <datagridtextcolumn              header="number" binding="{binding businessid}" isreadonly="true"              canusersort="true" canuserresize="false"             width="75"/>         <datagridtextcolumn              header="description" binding="{binding description}" isreadonly="true"              canusersort="true" sortdirection="ascending" canuserresize="true"             minwidth="260" width="auto"  />     </datagrid.columns>  </datagrid> 

update (working code)

i named column in xaml , put following code code-behind. if has got better idea or way optimize this, please let me know!

public partial class listing : usercontrol {     private double _currentcolumnwidth;      public listing()     {         initializecomponent();          loaded += onloaded;         sizechanged += onsizechanged;     }      private void onloaded(object sender, routedeventargs e)     {         _currentcolumnwidth = coldescription.actualwidth;     }      private void onsizechanged(object sender, sizechangedeventargs e)     {         // split if control not loaded yet         if (_currentcolumnwidth == 0) return;          // interested in width, not height         var widthchanged = e.widthchanged;         if (!widthchanged) return;          var delta = e.newsize.width - e.previoussize.width;         var newwidth = _currentcolumnwidth + delta;         if (newwidth <= coldescription.minwidth || newwidth >= coldescription.maxwidth) return;          _currentcolumnwidth = newwidth;         coldescription.width = new datagridlength(_currentcolumnwidth);     } } 

easy, replace width property in xaml

<datagridtextcolumn                  header="description" binding="{binding description}"                  isreadonly="true"                  canusersort="true" sortdirection="ascending" canuserresize="true"                 minwidth="260" width="auto"  /> 

to ...

<datagridtextcolumn                  header="description" binding="{binding description}" isreadonly="true"                  canusersort="true" sortdirection="ascending" canuserresize="true"                 minwidth="260" width="*"  /> 

you not require code behind handling of width wpf caters in xaml.

the "*" indicates autosize value :)
