Ya despues de mucho leer....y ver ejemplos
.....llegue a conseguir...el llenado de un gris en forma dinamica.....pero....aun no puedo hacer que dinamicamente de agregen tantos td como dias existan entre la fecha de inicio y la fecha de termino...
favor me pueden ayudar
lo q esta con rojo es lo que se me ocurrio, para hacer el loop para los td, ahora el problema es que el item5.text siempre esta vacio y necesti que se llene con el campo de la bd "dias", quew es el resultado de la resta de las fechas
la tabla de bd tiene 3 registros esta en access 2003, y se llama tabla1
la tabla tiene 4 columnas:
columnas :
a---------> tipo texto
b---------> tipo texto
c---------> date
d--------->date
y la consulta de donde extraigo los datos para llevarlos al webform es:
SELECT Tabla1.a, Tabla1.b, Tabla1.c, Tabla1.d, [d]-[c] AS dias
FROM Tabla1;
Aca esta el codigo:
