xaml code

    <grid>     <stackpanel>         <radiobutton groupname="grp1" content="enable textbox"  isenabled="{binding bttn1, mode=twoway}" ischecked="{binding bttn1}" checked="radiobutton_checked" unchecked="radiobutton_unchecked" />         <radiobutton groupname="grp1" content="disable textbox" isenabled="{binding bttn2}" />         <textbox isenabled="{binding txtbx1, mode=twoway}" bindinggroup="{binding grp1}" ></textbox>          <radiobutton groupname="grp2" content="enable textbox"  isenabled="{binding bttn3, mode=twoway}" ischecked="{binding bttn3}" checked="radiobutton_checked" unchecked="radiobutton_unchecked" />         <radiobutton groupname="grp2" content="disable textbox" isenabled="{binding bttn4}" />         <textbox isenabled="{binding txtbx2, mode=twoway}" bindinggroup="{binding grp2}" ></textbox>     </stackpanel> </grid> 

viewmodel code

    private bool _bttn1;     private bool _bttn2;     private bool _bttn3;     private bool _bttn4;     private bool _txtbx1;     private bool _txtbx2;      public bool bttn1     {                 {             return(_bttn1);         }          set         {             _bttn1 = value;             _txtbx1 = false;             raisepropertychanged(txtbx1.tostring());         }      }      public bool bttn2     {                 {             return (_bttn1);         }          set         {             _bttn1 = value;             _txtbx1 = false;             raisepropertychanged(txtbx1.tostring());         }      }      public bool txtbx1     {                 {             return (_txtbx1);         }          set         {             _txtbx1 = false;         }     } 

further down have

    public event propertychangedeventhandler propertychanged;      protected void raisepropertychanged(string name)     {         if (propertychanged != null)         {             propertychanged(this, new propertychangedeventargs(name));         }     }       private void radiobutton_checked(object sender, routedeventargs e)     {         handle(sender radiobutton);     }      private void radiobutton_unchecked(object sender, routedeventargs e)     {         handle(sender radiobutton);     }       void handle(radiobutton radiobutton)     {         bool flag = radiobutton.ischecked.value;          this.title = "ischecked = " + flag.tostring();      }      public class radioconverter : ivalueconverter     {         public object convert(object value, type targettype, object parameter, cultureinfo culture)         {             return !(bool)parameter;         }          public object convertback(object value, type targettype, object parameter, cultureinfo culture)         {             return !(bool)value ? parameter : null;         }      } 

in case want enable , disable textboxes radio buttons, solution works:

 <grid>         <stackpanel>             <radiobutton x:name="rb1" groupname="grp1" content="enable textbox" />             <radiobutton groupname="grp1" content="disable textbox"  />             <textbox isenabled="{binding ischecked, elementname=rb1}" ></textbox>              <radiobutton x:name="rb2" groupname="grp2" content="enable textbox"  />             <radiobutton groupname="grp2" content="disable textbox"  />             <textbox isenabled="{binding ischecked, elementname=rb2}"  ></textbox>         </stackpanel>
