asp.net databinding: Master detail relations in three levels.

Post by Frederik B » Mon, 12 Jun 2006 05:09:29


Hello,

I have managed to create a page with three drop-downs.
Each is bound to a SqlDataSource. The 2.level data source is filtered
using a WHERE clause that takes the top level selection as input. The 3.
level is filtered on the 2. level selection.

Things work fine, except when selecting on the top level the 2. level
(detail) list is refreshed ok, but the 3.level is not refreshed until
you make a selection on level 2....

Is it possible to "cascade" the postbacks or somehow achieve the desired
result?
