When I follow it through the debugger my function in the controller is being called and it is returning a record. I think there might be something wrong with my Jquery to retrieve the JSONResult.

I have a blackbox (with a crude ftp server on it) which has an IP address, a file on it, a username and a password. I have a PC logged on to the local network and I want to write a VB.net program that sits on the PC and when the file is created it downloads that file. from the laptop I can type ftp:192.168.43.34 in to windows explorer and see the file without having to type in a username or password (username is set to Anonymous)I require a simple program that just points to the file (ftp:192.168.23.12/banjo.txt) and grabs it to a local path (C:\banjo.txt)I have looked everywhere and not found anything that works and not interested in paying $500 for a library.

View 1 RepliesI have an application that has multiple UI layouts, sometimes on tabs, sometimes the occasional separate form.I recently bought a pack of UI elements, and I'd like to use a ribbon control as the main navigation. For the most part I want the tabs on the ribbon to function like your everyday tabcontrol. The problem is that the ribbon tabs don't each have their own page for you to lay out your controls like the normal tabcontrol does.So right now I have the ribbon control at the top of an MDI form, and instead of using multiple tab pages I have many borderless forms, and when I click on a tab of the ribbon, I maximize the appropriate form and bring it to the front. This creates the illusion of tab pages by eliminating the control boxes of the child forms.

I have a table with several rows of data that I need to return to the controller. In my view, I initially load the table by selection of a time period and clicking a button. The table loads all my relevant records but one of my table cells contains a dropdown list. So I should be able make a selection in the dropdown click "update" and my controller saves the changes.
So everything works until I try and save. The model that is sent to the controller is completely null. The list property I have tied to the table cells returns to the controller null.
