Object reference not set to an instance of an object.
I'm trying to replicate the situation you have in the Webforms app, where you first are presented with a list (of members) and from the list select an individual record.
So far, I have completed the first part but am having problems with the part where an individual record is selected from the list. I get the above error on the following line:
NiftyID = Integer.Parse(Page.RouteData.Values("NiftyID").ToString())
I'm not sure what the error message is trying to tell me or what it is I'm doing wrong. I'm also not sure what role the Web.Sitemap plays in navigation between forms (if any).
I've appended the the particular sub that's causing the problem below. Can you provide some clarification please?
I'm no longer getting the 404 error, so at least I think I'm now navigating to the right page, but the original message (above) is still there and I have no idea what is causing the error. Is there any help on this please?
