.net - Databinding an enum property to a ComboBox in WPF -

as example take following code:

public enum exampleenum { foobar, barfoo }  public class exampleclass : inotifypropertychanged {     private exampleenum example;      public exampleenum exampleproperty      { { return example; } { /* set , notify */; } } } 

i want databind property exampleproperty combobox, shows options "foobar" , "barfoo" , works in mode twoway. optimally want combobox definition this:

<combobox itemssource="what goes here?" selecteditem="{binding path=exampleproperty}" /> 

currently have handlers combobox.selectionchanged , exampleclass.propertychanged events installed in window binding manually.

is there better or kind of canonical way? use converters , how populate combobox right values? don't want started i18n right now.

edit

so 1 question answered: how populate combobox right values.

retrieve enum values list of strings via objectdataprovider static enum.getvalues method:

<window.resources>     <objectdataprovider methodname="getvalues"         objecttype="{x:type sys:enum}"         x:key="exampleenumvalues">         <objectdataprovider.methodparameters>             <x:type typename="exampleenum" />         </objectdataprovider.methodparameters>     </objectdataprovider> </window.resources> 

this can use itemssource combobox:

<combobox itemssource="{binding source={staticresource exampleenumvalues}}"/> 

you can create custom markup extension.

example of usage:

enum status {     [description("available.")]     available,     [description("not here right now.")]     away,     [description("i don't have time right now.")]     busy } 

<combobox      itemssource="{binding source={my:enumeration {x:type my:status}}}"      displaymemberpath="description"      selectedvalue="{binding currentstatus}"       selectedvaluepath="value"  />  

and implementation...

public class enumerationextension : markupextension   {     private type _enumtype;       public enumerationextension(type enumtype)     {       if (enumtype == null)         throw new argumentnullexception("enumtype");        enumtype = enumtype;     }      public type enumtype     {       { return _enumtype; }       private set       {         if (_enumtype == value)           return;          var enumtype = nullable.getunderlyingtype(value) ?? value;          if (enumtype.isenum == false)           throw new argumentexception("type must enum.");          _enumtype = value;       }     }      public override object providevalue(iserviceprovider serviceprovider)     {       var enumvalues = enum.getvalues(enumtype);        return (         object enumvalue in enumvalues         select new enumerationmember{           value = enumvalue,           description = getdescription(enumvalue)         }).toarray();     }      private string getdescription(object enumvalue)     {       var descriptionattribute = enumtype         .getfield(enumvalue.tostring())         .getcustomattributes(typeof (descriptionattribute), false)         .firstordefault() descriptionattribute;         return descriptionattribute != null         ? descriptionattribute.description         : enumvalue.tostring();     }      public class enumerationmember     {       public string description { get; set; }       public object value { get; set; }     }   }
