You need to inherit from Java.Lang.Object to implement the IJavaObject.Handle
property. Failure to do so will be Bad™. :-)

Alter your clsKeyListner type to take an Activity as a constructor parameter,
and use the provided Activity with subsequent FindViewById() calls:
class clsKeyListner : Java.Lang.Object, View.IOnKeyListener {
public clsKeyListner (Activity activity)
{
this.activity = activity;
}
private Activity activity;
bool View.IOnKeyListener.OnKey(View v, int keyCode, KeyEvent e)
{
if (e.Action == KeyEventActions.Down && keyCode ==
(int) Keycode.Enter) {
activity.FindViewById<EditText>(Resource.Id.txtSearch).Text = "updated value!";
return isEnterKeyPressed = true;
}
return false;
}
}
