data binding - WPF ListView columns dont update thair width in time -


hi have a listview gridview view 

<listview>     <listview.view>         <gridview.......

and in have few gridviewcolumn's want width of columns size largest item.. not work, seems on databind not update column size instead uses previous databind's largest item..

i have few styles modify layout:

<style targettype="{x:type listview}">     <setter property="borderthickness" value="1.000001"/>     <setter property="focusvisualstyle" value="{x:null}"/>     <setter property="borderbrush" value="{x:null}"/>     <setter property="background" value="transparent"/> </style> <style targettype="listviewitem">     <style.resources>         <!-- foreground selected listviewitem -->         <solidcolorbrush x:key="{x:static systemcolors.highlighttextbrushkey}"                                  color="black"/>         <!-- background selected listviewitem -->         <solidcolorbrush x:key="{x:static systemcolors.highlightbrushkey}"                                 color="transparent"/>          <solidcolorbrush x:key="{x:static systemcolors.controlbrushkey}" color="transparent"/>     </style.resources> </style> <style targettype="{x:type gridviewcolumnheader}">     <setter property="background" value="{staticresource primarybrush}" />     <setter property="foreground" value="white" />     <setter property="template">         <setter.value>             <controltemplate targettype="{x:type gridviewcolumnheader}">                 <grid background="{templatebinding background}" snapstodevicepixels="true" margin="2,0">                     <rectangle x:name="normal" />                      <contentpresenter x:name="headercontent"                                          horizontalalignment="{templatebinding horizontalcontentalignment}"                                          margin="5"                                          recognizesaccesskey="true"                                          snapstodevicepixels="{templatebinding snapstodevicepixels}"                                          verticalalignment="{templatebinding verticalcontentalignment}" />                 </grid>             </controltemplate>         </setter.value>     </setter> </style>

does 1 know why wpf behaves way? , there solution?

there seems answer here: force resize of gridview columns inside listview
have had use similar approach on datagrids columns when changing itemssources.
