If you are just adding a button, I think you can get by with just updating style: http://blogs.esri.com/esri/arcgis/2010/05/28/localizing-arcgis-controls/ and implementing its click event. But if you feel you would need to modify code/behavior, in the Toolkit source code, look for "CommitButton" in FeatureDataForm.Theme.xaml, this is the "Apply" button.

i already found apply button(from resource.resx) (whose name is commitbutton in featuredataform.theme.xml) and i also added "Cancel button" on upper right corner but when i handle its click event its give following error ...
"Line: 56

You can't directly add an event handler to default template of a templated control.
To hook up to events of anything in the template you have either to create a template part or to create a command to bind to.

That being said, as Jennifer mentionned, you likely don't need to modify the code of the control. Styling the control should do the trick.
