I've got an ASP.NET web application, and I'm attempting to reduce HTTP calls to the server, so I'd like to not load things like MicrosoftAjaxWebForms.debug.js and MicrosoftAjax.debug.js.
Script manager is used to form all of my external javascript files into one, and I'm concerned that this is causing other non-related libraries to be loaded.
I 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 recently upgraded from VWD 2008 Express to VWD 2010 Express. A problem has developed in that the website's graphics no longer appear in Design mode, there are "Error Creating Control" error messages that did not exist before, and also debugging errors that did not exist before. (Note: these problems did not exist when I first used VWD 2010; they may have originated with recent automatic Windows updates (I use Vista Home Premium SP2 with IIS 7)). The problem exists if I open the website either as a project file or as a website directory.

Debug-Start Debugging/Debug-StartWithoutDebugging OR Project ASP.Net Configuration launches Dreamweaver. It started lastnight, I had both Deamweaver and VWD 2008 express open at the same time - (I was looking at JQuery in the Microsoft and Dreamweaver enviroments simultaniously). After the first tie this happened, I closed down Dreamweaver (CS3) and it opened when I tried to run my VWD project. I reinstalled VWD 2008 express, IIS and disabled Dreamweaver (renamed the exe). Dreamweaver still came up.

But if I make the logout (destroing all my session variables) and I try to login a second time... it's not possible, I read that the user is already logged!!I have also tried to clear the cache after the logout but nothing changs, even if it is illogic because the code must work even if I don't do the log off...

there any way where i can make a page only accessible through a RedirectToAction? It's a bit dumb of a question given a redirect writes a URL.. I know it might sound a bit silly, but i really don't like the fact i have to be 'forced' to create a partial view to be able to make the page i want to redirect to. What i want to do is quite simply, after deleting a user account, redirecting to a page where it says, account deleted (with a bunch of other stuff), so its quite a simple task. I have no problem making a partial view here and there, but if i want to make many pages unaccessible, i think i would have to make most of the website in partial views haha. Maybe i'm getting it wrong though, i've read a couple of posts about it, including Phil Haack's ->http://haacked.com/archive/2009/11/18/aspnetmvc2-render-action.aspx But i'm still very confused about this subject,

I am working in ASP.NET using Masterpages, just wondering there is a a simple way of doing this using JQuery?
This involves using the Membership provider to add a comment to users server side records when they log in and out, and then confirming that when a cookie is used to authenticate, that the user hasn't logged out. This makes perfect sense to me. Where this starts to fall apart is that we do not currently use a membership provider, and so it seems like I face reimplementing all our authentication code to use a membership provider. We currently check authentication in a controller, and make a call to FormsAuthentication.SetAuthCookie() once we know the user exists. It would be a lot of work to force a membership provider in.
Is all this work really neccesary. Can I roll my own key value store of cookie values to logged in users and just make sure I clear this when a user hits the logout button. If this seems unsafe is there a way of implementing a minimal Membership provider in order to make these checks without handing off all authentication code to it?
I guess my main problem here is that we decided a long time ago that the membership provider model doesnt fit with the model we use for locking and unlocking accounts, and chose not to use it. Now we find that the MS recommendations specifically mention a membership provider, and as this is security I need to be sure that not using it as they recommend isn't going to cause troubles.

View 1 RepliesI am relatively new to ASP.NET and have searched the Internet to find guidance in preventing caching of web pages (in the latest versions of IE, Firefox, Chrome and Safari). Based on my search, I found a lot of conflicting/confusing info. As best as I can tell, it appears that I need to add the following 3 lines to the <head> section of my .aspx files:
[Code]....
if the aforementioned lines are correct and if all 3 lines are necessary? I have tried using different combinations of the 3 lines, but I get conflicting results (i.e., sometimes the page is cached and sometimes it's not).
I am developing a registration process which consists of 4 steps. Each step has its own action method. As such a user could type the url for each step as follows: bogusURL/Step1 //returns the View Step1 bogusURL/Step2 //returns the View Step2 etc... I would like to prevent users from gaining access to a step unless they have completed the previous steps. i.e. If they typed in bogusURL/Step2 without having completed Step 1 they should be redirected to the first step.
What is the best way to implement this?
I'm using a file manager-type WebControl that does lots of postbacks. It's placed inside a Page that is relatively complex. I would like to prevent the WebControl from causing the whole Page to go through the lifecycle.
Is there any way to isolate the WebControl from the rest of the Page? The only way I can think of is sticking the WebControl in a separate Page and creating an iframe in the original Page. Unfortunately that also means my WebControl properties/settings are no longer in the original Page. If I want two instances of the WebControl with different settings, then I have to create a Page for each setting and reference the correct one in my iframes. Not quite as "drag & drop" as I would like.
I want to show a confirmation dialog when a specific value is selected in an asp:DropDownList. If the confirmation dialog returns false (cancel) then I want to prevent the AutoPostBack.
<asp:DropDownList id="theDropDownID" onchange="foo()"></asp:DropDownList>
However, it ignores the returned value from foo() and actually does the postback. The generated code of the onchange event is:
foo();
setTimeout("__doPostBack('theDropDownID','')", 0);
so basically controlling the setTimeout that the .net adds, will do the job.
How can i prevent a user from entering the same data twice, i guess i need some validation in somewhere?For example:I add a name of a city, added successfully to the table.Try adding it again, click add and the program crashes.What type of coding do i need for this, some type of compare tool or something for the table?
View 1 RepliesI have a master template that all the pages on my site use. In the template there is an empty panel. In the code-behind for the page an imagebutton is created in the panel dynamically in my Page_Load section (makes a call to the DB to determine which button should appear via my controller). On some pages that use this template and have forms on them, pressing the Enter key fires the click event on this imagebutton rather than the submit button in the form. Is there a simple way to prevent the imagebutton click event from firing unless it's clicked by the mouse? I'm thinking a javascript method is a hack, especially since the button doesn't even exist in the master template until the button is dynamically created on Page_Load (this is ugly since I can't simply do <% =btnName.ClientId %> to refer to the button's name in my aspx page).I tried setting a super-high tabindex for the image button and that did nothing. Also set the button to be the DefaultButton in its panel on the master template but that did not work either. Moreover, I don't want to add a property to all of my pages that use this template (there are hundreds). It would be optimal to find a solution that works globally from my master template.I'll try to show our example here:We have a button on the top of each page in our system that lets you star the page as one of your favorites, sort of a server-side bookmark system. When the page loads it looks to see if the page is one of your favorites or not and then shows a gold star if it is, and a gray star if it is not. Clicking the imagebutton of a star toggles the page favorite status.In my master template (FullMenu.master) I have this panel
<asp:Panel runat="server" ID="pnlFavorite" style="display:inline;"></asp:Panel>
Next there is a class which creates the button and adds it to the panel on the master template:
public void InsertStarButton()
{
CreateStarButton();
[code]....
I have this simple code:
<asp:Label ID="litInfo" runat="server" meta:resourceKey="litInfo" />
<br />
<asp:TextBox ID="txtEmail" runat="server" /><br />
[Code].....
I am expecting the RequiredFieldValidator control to prevent a postback when the textbox is filled in with an incorrect data and the button pressed. What happens is that the validator displays an error message but a postback is fired.
When a user presses Button1 on the Webpage, I would like to copy slightly modified string from txt1 (Text) into txt2 (Text).
The problem is sometimes I get an error "a potentially dangerous request.form value was detected from the client validaterequest". I get this error when special symbols llike "<" or ">" are in txt1.Text.I've read about that problem. That error is to prevent from hackers who can input scripts into the txt1.All I did is:
1) Put validateRequest="false" into <%@ Page Language="VB" validateRequest="false" at Default.aspx.
2) Default.aspx.vb contains now:
sHTMLEncodedString = Server.HtmlEncode(txt1.Text))
[code]....
Now it works and allows to take any data from txt1, slightly modify it and put into txt2.So, my question is: Did a level of security was reduced after I wrote validateRequest="false" ? Any code should be added to keep the good level of security? Or, I'd better use another way to copy txt1 to txt2?
I'm just wondering what people use to stop user from click a submission button more than once thus creating many records. Does any one have any examples that take client-side validation into account. I have done much research on this but am yet to find a feasible solution.
View 1 RepliesI would like to create a module that is similar to the inventory system but not with a whole lot of bells and whistles. Basically, I have a jumper business and would like create a database to hold the items (jumper, pop-corn machine, etc.). I would like to have a calendar that when a user click on a date that he/she like to book my item only the available items display and not the one that is already booked. Pretty much to prevent the same item to get book by two different people on the same date. I also would like to create a form on the order page to have the booking information to go into the database.
View 11 RepliesI realize what I am trying to do is a little unconventional; but I want to make my search SEO. Basically I want the query string resulting from my search to be human readable; if I was doing straight html this would be cake:
<form method="GET"><input type="text" name="Zip" /></form>
I realize that I can change the form method in asp.net, however, all the asp.net state holders show up in the query string. I even tried disabling viewstate and removing all javascript submitting controls (to get rid of __EVENTTARGET) to no avail.
The thing is, I really want to keep using the same master page as I do in the rest of the site; does any one know of anything I can do short of building the page from scratch?
