View 1 RepliesI must be doing something wrong, but this makes sense to me. I have a Listbox loaded with tons of items from a datasource. A user clicks one of these items it grabs the selectedindex (an integer) and stores it in a HiddenField (works fine).
Now when the page does a complete a refresh (after postback) I want the ListBox to go back to that selectedindex that is in the HiddenField. Problem is, it seems that after postback the HiddenField is empty? Then I thought about storing the value in an Integer variable in code, but that is simply coming up as a zero at all times.
Question 1: What is the best/simplest way to do this?
Question 2: How?
I am currently grabbing it on selectedindex change

I 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.
I have a hidden value field on a page. On submit I post to a different page. On the page I've posted to I do a Request.Form but I do not get the value just a null value. This is the initial page

<form id="mainForm" name="mainForm" runat="server" action="Cancellation.aspx">
<h2>
Paid Bookings</h2>
<table cellpadding="0" cellspacing="0" border="0" id="booking_table">
<tr>

The javascript ViewCancellation function is set to a hyperlink in the code behind. The function will have a value like this,<a href="#" onclick=" View Cancellation(54666);return false;">cancel</a>.
string sResID = "";
protected void Page_Load(object sender, EventArgs e) {
HttpContext context = HttpContext.Current;
sResID = context.Request.Form["ResID"] != null ? context.Request.Form["ResID"] : "";
sResID = Regex.Replace(sResID, "/[^A-Z]d-/g", "");
context.Response.Write(sResID);
}

consider this scenario: a user on my website has a profileID. There are some pluginID's associated with this profileID.
E.g.: User1 might have 2, 3 and 5 plugins associated with his profile.
When the user logs in, I store the profileID of the user in a session variable cod. ON a certain page, the user tries to edit the plugins associated with his profile. So, on that page, I have to retrieve those pluginID's from the DB.
I have applied this code but this fetches only the maximum pluginID from the DB and not all the pluginID's.
[Code]....
I was trying to figure out how can I store multiple pluginID's in this session variable?

What I have below is currently working on my site to display information within an article. What I am wondering is that within a lot of stories I have more than one 'SchoolID' included. All of these IDs are in our database within the 'ArticleSchool' table and linked to an 'ArticleID.' The statement below is only displaying the first 'SchoolID' listed within an article. Is there a way I would be able to display every 'SchoolID' within an article to grab information from? Will it not work in a label if there are multiple values? The 'ArticleSchool' table has rows for every article and a new instance if more than one 'SchoolID' is attached.
