View 1 RepliesI am having some trouble with active directory authentication using FormsAuthentication in ASP.NET MVC 2 (VS 2010).
As I understand it I should be able to step into/through the Microsoft source code for FormsAuthentication.Authenticate if I check 'Enable source server support' and 'Enable .Net Framework source stepping' in Options->Debug->General and specify 'Microsoft Symbol Servers' in Options->Debug->Symbols.
I have done this and can step into a whole bunch of MS source code, but not FormsAuthentication.Authenticate. The debugger simple steps over it.
If I could step into FormsAuthentication.Authenticate it would make my life a whole lot easier.
I was trying to debug the applicatioons but after certain amount of minutes (say 3 minutes), the step into (F11) will act as F5.

View 2 RepliesI want to debug EditPanel.debug.js file of HTML Editor, but it never shows in VS 08 and Im sure it executes to that line.What I did to enable debuggingUnchecked both 2 checkboxes for disabling the debugging
Set ScriptMode="Debug"
Change following line
[ClientScriptResource("AjaxControlToolkit.HTMLEditor.EditPanel", "AjaxControlToolkit.HTMLEditor.EditPanel.js")]
to
[ClientScriptResource("AjaxControlToolkit.HTMLEditor.EditPanel", "AjaxControlToolkit.HTMLEditor.EditPanel.debug.js")]
I'm developing an ASP page and I noticed odd behaviour when I'm trying to step through server side call backs. Specifically some of the time, when I press F10 to execute the next statement the debugger acts like I pressed F5 to continue and takes off. Some of the time stepping works and some of the time it doens't. In addition, testing the same call back I can sometime step several times before it takes off and other times as soon as I click F10 it takes off. If I set explicit breakpoints it will always hit them but as I said, stepping often results in the debugger not stoping on the next statement.
I feel like I didn't have this earlier but I'm mystified as to why it is doing this
I moved from the FileUpload control to the AsyncFileUpload control.
1) Do AsyncFileUpload controls work under UpdatePanels??? (Please provide example or reference)
2) Can AsyncFileUpload controls be triggerd with an update button (both inside the same updatepanel)?
I have a problem on my website, when using updatepanels:
Most of the time everything works fine, but a few times a day a user will get an error 500 as response to a partial postback in an updatepanel. The problems are:
1) I can see in my server logs that the request is processed without errors.
2) There is no log entry from the function handling AsyncPostBackErrors, although that is the first thing it does.
3) The function handling AsyncPostBackErrors changes the AsyncPostBackErrorMessage, but the users see a generic text which the function will never output.
So my theory is that the request does not cause an syncPostBackError at all. I can see in the logs, that there have always been an AsyncPostBackError from another request at almost the same time. So I suspect that one request somehow gets tainted with the error of the failing request.
On my page which uses nested master pages, I have several user controls which are in their own UpdatePanels.
I've noticed that when I update something which is in UpdatePanel 2, things are shifting slightly in UpdatePanel 1. Someone told me that when UpdatePanels are used, the page is reloading anyway. Is this true?
How do I prevent UpdatePanel 2 affecting UpdatePanel 1?
P.S. All update panels are set to Conditional in their UpdateMode's.
I just want to make sure that I got this right. If I have two update panels, and updatepanel1 has 10 dynamic controls created from an external button that resides on the page by default.. and then i have a second button which also is on the page by default but is an asynctrigger to updatepanel2...
then when the first updatepanel1 is populated with dynamic controls, then when I click button2 to update the second updatepanel2 with some data, the dynamic controls in updatepanel1 wil;l still remain there right? but does it persist by itself on postback? And if so why?
because when I click button2 to update updatepanel2, it does a partial page postback. So when it does a partial page postback, does that mean it does not destroy updatepanel1's dynamic controls?
is there any disadvantages if we use more UpdatePanels in our application.
View 4 RepliesI am fairly new to ASP.NET and just started using UpdatePanels.Here's what I'm trying to accomplish. I have a button which is wrapped up in the UpdatePanel like so:
[Code]....
The following is the mark-up for the textbox which is supposed trigger an update when its text changes:
[Code]....
With the current set-up, the button's text doesn't change when the textbox content changes. At first I suspected that the reason it didn't modify button's text was because I didn't set AutoPostBack to true on the textbox (tried enabling and it didn't work though),
but then I why would I want to? I'm not getting any data from the server - I just want to update a button on the client side.
I'd really appreciate if you could point out what I'm doing wrong and maybe also clarify when AutoPostBack is absolutely necessary and what are some of the special cases in which it needs to be used.

I am using asp.net sitemap with the in-built asp.net menu but this is very 'dull'. I want to apply CSS and jQuery to give it a better visual look and feel. I have read various articles based on [URL] However, i really liked [URL]

I am using a wizard with 2 steps: Step 1: I enter some values in few textboxes, which in turn are stored in some hidden variables Step 2: There are some more textboxes including the texboxes in step 1 Example: in step 1 there are two textboxes Customer Name & Email ID In step 2 there are two more texboxes Customer Name, Email ID, Company Name and Age Now the values in step 1 are stored in 2 hidden variables lblCustomerName and lblEmailId respectively. Now how do I automatically populate these two fields which are already entered in step 1, in the textboxes present in step 2, is my question?

I have a project to completely rewrite the site [URL] and want to do it in ASP.NET rather then PHP, and since I do not know either language I would rather learn this one instead.
My question is simple, where do I start? I learn well by reading books and doing examples and building example websites, that sort of stuff. Can anyone suggest any good book titles that will get me started in the right direction? A friend sent me the PDF version of the book: "Learning ASP.NET 3.5, 2nd Edition (Build web applications with ASP.NET 3.5, AJAX, Linq and MORE)." This is so far the only resource I have. The only thing about that book is that it promotes using the WYSIWYG style of web design and I
have always been tought to stay away from that.
I have created a User Control with 2 Textboxes and a Button. Then I have built that control into my Master Page. I have also created the code easily enough for the login - see below;

2. Let them Logout

What is the easiest way possible to do this, as I do NOT want to use the Asp.Net Login facilities already provided.
I have been reading a lot about UpdateMode set to Conditional on multiple UpdatePanels on a page. It seems that when set to Conditional only the UpdatePanel affected by the event will refresh. It is not happening on my case and I don't know what am I doing wrong.
This is the scenario. I have 4 updatePanel all set to Conditional. I have external buttons that will call the Update method per each panel but the whole page refreshes when I click on any of the buttons.
Here is a sample code:

I have a page in which there are multiple updatepanels and each of these update panels are trigerred by different triggers.
These update panels are used to do Async post back and the page is updated with the data retrieved from the async post back.
Now the issue i am facing is that since there are multiple update panels, the update done by one panel is lost when the other panels does the post back.
let me know if any one knows on how to solve this issue.

I seem to be having issues trying to programmatically update one of the UpdatePanels on a page i'm developing.Basically what i'm trying to do is...
have one update panel on the master page (used to show summary info like errors and success message) and then a updatepanel on the content pages, all of which are conditional. where its not working (or i'm doing something wrong) is when i call a method in the master page to update its updatepanel to show the new summary message it does nothing.
i.e. (content page)
page_load()...
{
try
{
load content. [code]....
We currently have a page with several user controls (8 of them) and when a control that is contained in an updatepanel initiates a postback the focus is not retained. In some cases, it looks like the focus is sent to the top of the page, and in other cases the focus looks like it is sent to the control with the TabIndex=1.
I have tried 3 different solutions and they all end up with the same result.
The first two were from article:
[URL]
Solution 1: At the end of the server event executed in postback, add:
[Code]....
The article says both of those solutions worked, but for us, neither of them did.[Code]....
ASPX.CS
[Code]....
[Code]....
In all 3 scenarios the control we want to have the focus gets the focus for a split second and then the focus is cleared (set to the top of page, or TabIndex=1).
