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:

oCon.Password = "sa"
End Sub

Dim _insert As New System.Data.SqlClient.SqlCommand("INSERT INTO CONTB_SECUENCIAL(Int 32 SECUENCIAL_INGRESO, SECUENCIAL_EGRESO, SECUENCIAL_DIARIO, SECUENCIAL_ASIENTO, SECUENCIAL_RETEN_FUENTE, SECUENCIAL_RETEN_IVA) VALUES('" + Me.txtIngreso.Text + "','" + Me.txtEgreso.Text + "','" + Me.txtDiario.Text + "','" + Me.txtAsiento.Text + "','" + Me.txtFuente.Text + "','" + Me.txtIva.Text + ")")
oCon.Insert_Command = _insert
Dim status As Boolean = oCon.InsertFields()
End Sub

Dim status As Boolean = oCon.DeleteFields()
End Sub

Hola, si no te da ningun tipo de error te recomiendo que debuggees la aplicacion a ver que esta pasando. Si no da error ni ejecuta las sentencias es que no pasa por ellas. Haz un debug y sigue el ciclo del progrma a ver que pasa
