c# - Getting Error in Xaml while Binding data with Converter -

i getting "invalid xaml" error while binding data converter. see screenshot:

this xaml code:

<datatemplate>                         <border borderbrush="#cbc6c0"                                 borderthickness="3"                                 cornerradius="3"                                 background="#fff9f6f4">                             <grid margin="5">                                 <contentcontrol content="{binding   converter={staticresource groupdetails}}" />                             </grid>                         </border>                     </datatemplate> 

... , c# code converter:

public class listdetailsconverter : ivalueconverter {     public object convert(object value, type targettype, object parameter, system.globalization.cultureinfo culture)     {         model_detail objdetail = value model_detail;          textblock tbinfo = new textblock();         tbinfo.margin = new thickness(5, 5, 5, 5);         tbinfo.textwrapping = textwrapping.wrap;         tbinfo.foreground = new solidcolorbrush(colors.black);          bold tbtitle = new bold();         string strtitle = objdetail.questiontitle;         tbtitle.inlines.add(strtitle);          string strdetails = " : " + objdetail.detail;          tbinfo.inlines.clear();         tbinfo.inlines.add(tbtitle);         tbinfo.inlines.add(strdetails);         return tbinfo;     }      public object convertback(object value, type targettype, object parameter, system.globalization.cultureinfo culture)     {         throw new notimplementedexception();     } } 

at top of page xaml have declared:

 xmlns:myconverter="clr-namespace:magnitude_gold.mgconverter"  <phone:phoneapplicationpage.resources>         <myconverter:listdetailsconverter x:key="groupdetails" />  </phone:phoneapplicationpage.resources> 

what wrong this..?

use this, replace model_detail enity or object

<contentcontrol content="{binding  path=model_detail converter={staticresource groupdetails}}" />
