Tengo un método que crea una tabla y luego crea un repetidor justo después, la tabla se renderiza pero el repetidor simplemente no se representa. El siguiente método simplemente crea una tabla primero, rellenándola con información, luego construye dinámicamente un repetidor que funciona bien, pero luego no representa el repetidor en la página aspx. Intenté usar el generador de cadenas para devolverlo como una cadena, pero aún no funciona. Aquí está el código a continuación. Gracias
