How do I prevent the page from reloading when ever I click on a checkbox?This can be cumbersome when I have hundreds of checkboxes.Below is my code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then

I have a very simple ASP.NET project. It consists of two pages.The first page (FirstPage.htm) has the following markup:
[Code]...
So page one has a hyperlink that loads page two in a popup. Page 2 has a button that should do nothing. However, when I click on the button a new window pops up and loads Page 2 again.
If I navigate directly to page 2, nothing happens.I'm thinking I must have some odd configuration either in VS or in IIS that's causing it; but I have no idea what.
I am using ASP.net(2.0) with VB.NET.
I have a User registration form. On that form the user supply all his contact details and he can upload a image with the normal file upload control in ASP.net.
This is my problem. If anything goes wrong on the page then i give the User a error message saying what he left out or what went wrong. But the page refresh when that does happen. NOW the link to the image the user selected is gone. NOW when the user fix his error he thinks that he is uploading a picture but he never did because when the page re loaded it removed the link to his image inside the file upload control.
Note, the user don't have to upload a image, so there will be no error when the field is blank.
I'm new to using httpwebrequest i've always just used webbrower controls but want to get away from doing that for obvious reason with that said.
I'm having it go to a wepage there is no login what so ever. but there is a cookie that holds saved data from the page. when in IE or any other brower you click an option from a combo box and it reloads the page and saves that data to a cookie.
CODE:
if you just do a httpwebrrquest it goes to 1 - Home what i'm trying to do is get to 25 - Page2 the cookie has the Sid number i'm been searching and reading for atleast 10hrs now and not even close to anywhere farther than i was. if i used Webbrowser it would just save the cookie for me automaticly but want to get away from hearing the clicking and wasting time of downloading all the pictures and stuff.
How does the CheckBox control draw that black check mark in the white box? I can't install .Net Reflector or anything here on my work machine so could someone post the code (vb.net or c# is fine with me)?
Or if anyone knows how to do it (I have an 8x8 Bitmap object I'm drawing on already) I'd like a hand since my math isn't working out correctly[code]...

I would like to be able to time a page load time in ASP.net (VBscript). Adding Trace="true" to the page directive is nice, but I need to actually time an event and store it in a variable.In ASP it was easy with the Timer object, but in .net I can't find anything on Google.

How to store the state of my check box list tick boxes accross the page life cycle? Here I have a unbound checkbox list control where values comes from xml file. How to retain the state? Moreover, when I click on Next button to the new page and comeback state is retained. But when I click on the back button and come to the same page state is not retained.

How can I check the 'Checked' property of a dynamically-created checkbox during the Page_Load subroutine? Basically, I have a VB.NET page that creates some table rows dynamically, based on a number selected by the user. So, for example, if the user selects "3" from a dropdown list, the page posts back and creates three table rows. Each row contains a couple of textboxes, a dropdown list, and a checkbox (which are all .NET form controls rather than plain HTML controls, I should point out).Typically, the user would enter a few details into the form controls, and click the 'Submit' button, after which the page iterates through each row, and inserts the data into a SQL Server table.But if the user ticks the checkbox for that row, this signifies that the page is to ignore that row, and NOT insert that row of data into the database when the user clicks 'Submit'. This works well, but there is a problem. If the user clicks 'Submit' and some of the values entered into the form controls are invalid (so, for example, the user didn't enter their name) then the page won't submit the data, and instead, shows an error to the user informing them of the values they need to change. But if the user creates three rows, for example, but decides to "ignore" the third row (by ticking the checkbox) then when the page posts back, finds some invalid entries, and re-shows the form to the user to allow them to correct any errors, I'd rather the page didn't render the third row altogether. After all, they chose to create three rows originally, but then decided that they only needed two. So it makes sense that the third row is not recreated.
But what seemed to happen was that objCheckbox.Checked was always returning False, even when the checkbox was ticked. Once the page had loaded, the table rows had rendered again, and the tick was present in the checkbox, so it's not like the value was lost on postback. But at the point I check whether the checkbox is ticked, it always returns False, rendering a table row that the user doesn't need.Does anyone know how to get round this problem? I've read lots of articles about the .NET ViewState, and the page lifecycle, but I've yet to find a solution that works. I simply need to be able to check if a checkbox is ticked before re-creating some dynamic controls. [code] But then I basically found out that you can't override a protected member with a public one.
I have a ListView that contains 3 checkboxes per row. I want to set it up so that only one checkbox can be selected at a time. Here is my current CodeBehind...
Public Class MyClass
Dim Checkbox1 As Checkbox
Dim Checkbox2 As Checkbox

Let me know if I need to include anything else. Right now when I click a checkbox and another checkbox is selected then both are selected instead of just the new one..

View 5 RepliesI have aspx gridview with checkbox on evryrow, what is required is whenever we check any of the rows, a query should be launched to change the specific agent -each row consist of agentID, Pass, Status- to Paid Status. using javascriptWhat I need to know is how to loop to get the Checked row and get the ID of the row checked so that I can get THe ID of the Agent in thos row so that I can update its status.using javascriptI found something similar on stackflow:t GridView selected row DataKey in JavascriptBut it is not my case, what is needed is at the check of a checkbox a javascript function should launch through which I could update the selected row in grid view after having the index of this row and this all to avoid refreshing the page.

I am having an asp.net page which i was showing as a pop up using Nyromodel. the page contains
4 div which is showing as Tabs (using Jquery Tabs). 4 Repeater . Each repeater I am having a custom control and I am setting the value from db by setting the datasource to repeater. (This query may have 300-500 rows). 1 infragistics UltraWebGrid. I add selected values to the grid.
So the problem is it is taking too much time to render if I perform any operation in that UI. I logged the sp execution time, then I found that SP i taking only 2-3 seconds. But the control will render completely after 30-40 seconds. So sp execution time alone is not enough to satisfy the my lead. how to analysis the time of rendering the control.
I have a simple WinForm that is using a Tab Control to simplify data entry. The very last page has a text box that allows the user to "set a name" for the file. I really want to simplify this and suggest how the file should be named. What I want
is for when the tab page is entered (consider that generically) that the text box is pre-populted with a name.
This code will do what I want, but only the first time the tab page is entered. what I am apparently missing or a better way to do this?
Private Sub TabPage6_Focus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TabPage6.Enter

I'm reading about the WPF Navigation Services and I have a general question.At run-time I want to be able to parse an external XML file that has information about an UI (i.e. a series of screens) and then in the code-behind create a WPF Navigation service with multiple Pages. Is it possible to create a new WPF Page at run-time or do they have to be created in Visual Studio first?

The web page I am trying to download is a intranet site. I am periodically downloading the web page for archiving purpose for future reference. The web page will list the current active jobs/projects we work. We process 100's of jobs everyday. The list item will have the Project id, Project name, Project deadline, etc.The download works fine. the web page is downloaded locally. The problem is the date/time format is changed to some other format. If I view the web page in browser, the deadline of one of the project shows as "7/15 03:00".
However, the downloaded webpage shows the deadline of that project as "Wed Jul 14 16:30:00 CDT 2010". I believe it shows in CDT timezone. Also, it shows couple of other timezone too. I think the project might be created from those countries. I am in India timezone.
