View 14 RepliesI have a gridview where there is a column of checkboxes for the user to check on for the products he/she wants. After checking, they will have to click on a button. for every checkbox that is checked, the result will be stored in an arraylist. after the button is clicked, the label will show the count of the number of objects in the arraylist, which is the number of items that were checked. However, it appears that objects are not being added to the arraylist. What's the problem? Below is some portion of the code for more understanding.

I am using ASP.Net + .Net 3.5 + VSTS 2008 + IIS 7.0 + C# to develop a web application. I want to count how many users are online. This is my current implementation,when Session_Start is called, I will increase # of users online by 1;when Session_End is called, I will descrease # of users online by 1.Two quesitons,A Is that implementaiton correct?B. Another question is, I think this method can not track # of users of real time, since when user closes the browser, Session_End will not be called immediately (Session_End will be deferred to be called). Correct?
View 3 RepliesWe have a ASP .NET application which will be deployed in a web farm. We would like to find the total number of sessions that have been established. If we create a counter in global.asax.cs, it will be able to count only within aspnet_wp process. In a web farm, multiple nodes will have IIS on multiple machines. If we use SQL server-based session management, can we get the total number of active session by querying the Session DB? If we later decide to use session state server to store the sessions, can we get the number of active sessions?

I have radiobuttonlist where data bind from tables.I want to give different tooltips to each item in RadiobuttonList.
for eg. Admin :- Acess to all functions
User:- Acess To Limited functiuons
Supervisor :- Add data of user.
Above is sample of each item from radiobuttonlist and tooltip for the same.
I used this Read DataTable values one by one for making Quiz (only one question on page). But now I want use random for it. Like this: Refresh / Sort / Rearrange RadioButtonList items (options) on Button click in ASP.Net
How I can solve this?
I am writing a form which has a set of options (radio buttons), and under each option, there is another set of options. For example:
- Session 1
- New Book A
- Used Book A
- Session 2
- New Book B
- Used Book B
I've tried using HTML <input type="radio", and <asp:RadioButton, but even though I assign the "name" attribute correctly, the buttons are not mutually exclusive -- i.e., you can click both within each group. I see in "View Source" that the name and ID are altered, and therefore become ungrouped by the ASP.NET processing. I've tried using <asp:RadioButtonList, and this works functionally, but the items are not grouped properly. They appear like this:
- Session 1
- Session 2
- New Book A
- Used Book A
- New Book B
- Used Book B

i have a radio button list that on selecting, queries a table and displays data in a textarea. now i'm trying to enhance my code so that the value of the radio button is displayed within the URL. that way i can send users links to content displayed by the radio selection (i.e. articles).
So far i've been able to place the "Article_PK" within the url successfully when the user makes a selection. now i'm just stuck on how to get my databind working again. so basically, i need to read in the value of the "Article_PK" in the url to display the data within the textarea. need someone with some mad coding skills to save the day!

After editing the list of hardcoded items in a RadioButtonList on a ASP.NET page via the Design view, I find that the HTML source for the RadioButtonList still does not update to the latest list of items i.e items are still the ones before the changes.
Is there a way to synchronize what appears in the Design view and the actual HTML source? Or do I have to delete the RadioButtonList and recreate it?
How can I force back focus on to selected radiobuttonlist item in the updatepanel? It keeps loosing focus when an item got selected.

View 4 Repliesi read article "using javascript with asp.net radiobuttonlist control" and i found it useful.
[var RB1 = document.getElementById("<%=RadioButtonList1.ClientID%>");
var radio = RB1.getElementsByTagName("input");
if am setting radio[1].checked = 1; the item is checked. ]
step1: radio[0]=checked
radio[1]=not checked
radio[2]=not checked
step 2: by using javascript , am changing the selection
now
radio[0]=not checked
radio[1]=checked
radio[2]=not checked
step 3: if am changing radio[0]=checked by clicking, it wont fire the selected index change that i wrote on code behind
but if am changing radio[2]=checked by clicking, it will fire the selected index change that i wrote on code behind
My requirement: i want to fire the selected index change in both cases. for that i need to change the selected index in step 2.
How can i get the number of a listview records (or the index of the last record) from within the ItemDataBound event ? I would like to hide one of the controls in the last record, how can i know if the item is the last one ?
View 2 RepliesI experience a strange issue with DropDownList today.
It is bind to SqlDataSource which produce about 1500 item. SqlDataSource working properly and no mistake in SQL.
When i bind it to a DropDownList, first item automatically selected on load. But if i try to select other items, DDL never renders. Width of DDL shrinks to zero. But if i use UP and DOWN arrows, i can go through items which appears on the first line of DDL. Shortly, DDL never render a LIST of data for me as it is supposed to do.
If restrict the data as "SELECT TOP 100 SupplierName blabla..", the DDL works properly. Is there any data limit in DDL? 1500 line is massive for DDL?
With the same SqlDataSource, ListView control is working succesfully.
