Hello. I'm starting with web services and I'm facing a problem I can't solve or find documentation anywhere.
I'm developing a web page and showing a Job Card. I want the users to update data, and I want data to be saved in Nav database, but I don't know how to do it. I'm using TextBox to show the fields, and I've tried the Update method from the WebService with fixed values, but I don't know where I have to execute this Update method, because when I call it, the data has disappeared because of the PostBack. I've even tried with CustomValidators, but I don't get any positive result.
I've also search for help on the internet but I can't find an example for doing that, and I think it has to be some easy way to do that but it's only I can't find it.
Where should I put the Update?
