How to bind 2 Odropdown when creating a record for a grid
Title:
B
I
{code}
?
I have an entity Phones which is displayed in a Grid. When I create a new record, I have to fill 2 fields: - Site - Free phone number The viewmodel for input is : [UIHint("Odropdown")] [AweUrl(Action = "GetSitesSQL", Controller = "Data")] public int SiteId { get; set; } [UIHint("Odropdown")] [AweUrl(Action = "GetSQLFreeTelephoneNumber", Controller = "Data")] public string LineURI { get; set; } In my create view, I have these 2 dropboxes. I would like to bind dynamically the Free phone number dropdown with Site dropdow. I mean, if I choose I site (for example Geneva), I would like that my dropdown box "Free phone number" display only phone number from Geneva, If I choose Zürich, it will only show Züriche phone numbers. So each time I change the selected value of my Site dropdown box, I have dynamically a new list of Free phone numbers in the other dropdown box. How can I do that ? Thanks
