View 4 RepliesState Management :: Hidden Field Value In User Control / Make The Hidden Field Save Its Value?
Mar 23, 2011I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
MVC :: Session Variable Versus Hidden Field?
Jun 8, 2010I have an application that goes through a series of questions and I have a view that shows each question based on the ViewData.
I would like to store the QuestionID (the view uses this to determine which question to show), but I'm curious if I should be storing the CurrentQuestionID in the Session or as a hidden field?
I am sure this is pretty common and I was curious what the conventions/best practices were for this sort of thing.

View 5 RepliesC# Get Custom Attribute Of Hidden From Request.Form
Jul 22, 2010I have some code which is rendering some custom attributes of Hidden Control (without runat=server).
Something like,

When I submit the form, I am looping through a set of ids, say 1200 to 1250, so I will read controls based on that, and also hidden with Request.Form["hdn "]
Now problem is, as we know we get value attribute from form when we do Request.Form["id"] for hidden, I want to read my custom attributes from hidden element. Is there any way? Note that, I can not touch the rendering part here.

Sep 6, 2010I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.

Feb 2, 2010This is probably a simple question, but I can't seem to find an answer. One of my web pages has an ASP.NET FormView and two SqlDataSource controls.
