Buen dia a todos, tengo una gran duda y me gustaria que me agudara.
Tengo un Tree y un Grid en un solo formulario (Trabajo: C# + Silverlight + DevExpress) y los datos del tree son los mismos que el grid, es decir cuando doy dobleclick a un nodo del tree y si hay hijos, pues el tree se expando y los hijos tambien aparacen en el grid, ahora mi problema es que me gustaria darle dobleclick al grid y si hay hijos pues que reacargue el grid y lo que deseo es que tambien se expanda en el tree...
Les agradeceria mucho si ayuda.
Saludos!
