View 3 RepliesAccess <asp:table> table rows added by javascript in asp.net webform . Apologies for the duplicate question but I'd really like an explanation why this is the case. It is probably due to my lack of understanding on how browsers process HTML tables on submission to the server.If I have a <HTML> table or an <asp:table> control on an aspx page and I add rows to it client-side using JQuery / Javascript, why can I not include these added rows in a post-back to the server?
I've been trying to get this to work and it looks like I can't do it based on the answer to the previous question. But can someone explain why this is the case? The table itself can be returned in the post-back but the only rows present are the rows that were part of the table when it was sent to the browser originally - it does not include the rows added by the browser.there was a way to include these new rows in the post-back, the same as any client-side user input?

I'm looking for a way to pass some sort of credentials or Authorization token from a VB.Net Client to an ASP.Net web application that allows the Client to auto-login to our Forms-Authenticated website. If a user is logged into a local application, I want them to be able to view some web pages without having to login to the website as well. The credentials are not the same between the apps, but I would just like to pass some sort of encrypted token or key to the web page so I know they are coming from the desktop application. Is this possible without requiring a username and password login?
I also need to make sure this URL that is used cannot be simply copied and used from another location, so I'll need to include some sort of information in the encrypted value to know where it's coming from.I know how to login the user with Forms Authentication and all that, just need to figure out the best way to secure this.
