DESCRIPCION DEL PROBLEMA
Tengo una aplicación realizada en ASP.NET,
- En un formulario web que esta heredado de un masterpage.master.... este formulario se llama secuenciales.aspx.vb
- En el formulario secuenciales.aspx.vb un SQLDATASTORE, asociado a una base de datos realizada en SQL 2000, cuyo servidor se LLAMA DESARROLLO y la BASE SE LLAMA BASE.
- Tengo un DATAGRIDVIEW para ver los datos de la tabla CONTB_SECUENCIAL.
- En secuenciales.aspx.vb tengo varios botones: GRABAR, BUSCAR, ELIMINAR, ACTUALIZAR, con la siguiente programación:
