I have successfully implemented a page using a custom verison of the HTML Editor. Now I would like to check to see if the user has modified the content in the editor window and prompt them prior to leaving the page.
I am trying to do this in client side java script (but would be happy to do it server side) and can not seem to detect if there is even content in the HTMLEditor control, so there is no way I will get to the point of seeing if it changed.
I'm running a 2.0 .NET app on my local machine; the app uses Global.asax to trigger logic at both Application and Session Start. Up until this week, session management in this application was behaving normally. Now, after no apparent change to my system, it is not. The application has a sign-on screen at startup, in which the user selects a user profile, and proceeds to a main menu. The user info is stored in a Session object, and carried forward to the main menu for the remainder of the application. Normally, a new session is created when the user times out; however, I am finding now that, on my machine, a new session is created on each form change (Response.Redirect, window.open, etc.)
Web.config for the app, when testing locally, uses a <sessionState> setup of 'mode="InProc" cookieless="false"'. My IE7 browser is set up to "Always allow session cookies". When I attempt to run the app 'cookieless="true"', it works up to a point where a popup form is displayed, at which point a new session is created, and the Session_Start logic kicks in, where I lose my user info characteristics. This in turn triggers logic which assumes the user timed out, and a "Session Expired" screen is presented.
I do not have IIS installed locally; ASP.NET is used for session management. I have tried setting the timeout to an extremely high value, without effect.
From ASP.NET Webforms I am used to change the content of the form dynamically during the postback. During the postback I can add textboxes, dropdownlists on the form. But I did not find anything similiar in MVC.
My problem is that I have a form a I would like to change the elements on the form programatically - the user selects the radiobutton or change the selection of the dropdown list and I would like to add some textboxes and so on the form = I would like to react on the user inputs dynamically.
I have a form with 4 independent gridviews and I want to make some other controls, like the form's update button, visible when the gridviews have been corectly completed. I believe I should be doing this Client side so I have written Javascript that successfully evaluates the gridview controls for presence and correct data. Now I need to get the form to run this function, preferably in something like the gridview's onchange event, something that doesn't exist.

View 3 RepliesI want to make the results of an ASP.NET form POST "bookmarkable", and I'm thinking of using query parameters to accomplish this.

View 1 RepliesI am working on Login control and I am new in ASP.NET. So far what I did is :
1. In Website->ASP.NET Configuration I change the form authentication to internet.
2. I created a user profile
3. This gave me a ASPNETDB.mdf database.
4. I added this code :

I'm not entirely sure which forum this belongs in. It works with both my ASP.NET form and my SQL DB.
Okay, I built an application from scratch a couple years ago and am trying to add some functionality so I don't have to do so much manual work.
I have two relevant tables, tableClasses and tableStudent2Class
Classes have 4 possible sessions that are available. These are bin fields which I mark as true if they're available for registration. There are upwards of 40 different classes that are available. Each class has a defined number of slots available (an int field).
The tableStudent2Class connects the tableStudents to tableClasses. There are three fields: classID, classSessionNumber, and studentGUID.
Now, is there some way to make the DB and/or form change the available bin fields to false when they receive a certain number of registrations?
I'm trying to change the values of some of the controls in the ASPxGridview Edit Form, however they are not changing. It seems to be resetting?
How can I do this and in which event would I do this in?
I have quite a simple requirement, but strangely can't seem to find anything relevant & I'm not able to currently get it to work. I have created a master page with a a page header and footer, and left two contentplaceholders in it, one to add to the <head> html tag and one in the <body>. The idea is that users can then easily change the content or title of a page in a table without having to open an IDE of any kind.
The result is my page template looks like this:
[Code]....
Basically, I want the user to be able to paste all of their HTML into a DB table, and I will pull it out and put it into these placeholders. Most methods I've seen involve using extra controls, but surely there is a way to just enter text (that will be html) between the <asp:Content></asp:Content> tags on the Page_Load event?
I am trying to change the connection string for the registration form in VS 2010.
This is because it links to the local database in the App_Data which I need it to link to another database. I have changed the connection string in the webconig file and this works file for other forms I have created but does not allow me to create new users.
I have used the ASP.net 4.0 template when creating this website.

View 1 RepliesI have an edit profile form for my website, and I'm adding a section at the bottom of the page where the user will be able to update his password (in addition to editing his profile).

I'm trying to write basic validators for such a form, which I'm having trouble with and could use soem help on. For instance, I'm trying to write a validator: 1) that checks whether the value of the currentPWD and changePWD. If currentPWD is empty and changePWD is not, then the validator needs to signal to the user that a value for currentPWD is needed. This is my validator but it's not working:

I noticed that the custom validator is declared before the Textbox "change_password" is.. I'm not sure if this could be the issue..

1) I notice that the module gets it's data in chunks. This is problematic for me because I'm using a regex to find and replace. If I get a partial match in one chunk and the rest of the match in the second, it will not work. Is there any way to get the entire response before I do my thing to it? I have seen code where it appends data to a string builder until it uses a matches on an "" end tag but my code must work for more that just (xml, custom tags, etc). I don't know how to detect the End Of Stream or if that is even possible.

I have been developing a quiz application in asp.net mvc. In this quiz user is give a list of topic to take quiz. On click of one of the topic the user is taken to new page. In the get part action of this page i have taken some parameters, generated questions for the quiz, register quiz for the user (save in db)and save the generated questions in db.
Now the problem is:
User see the page, if user hits the "submit" button after selecting the answer than it is ok but If user refresh the page. Then the get action is called again and new set of questions are generated and new quiz is registered to user.
How can i avoid this?
Is there any way to detect that the get action is called the second time or to detect page refresh in as.net mvc.
If you could suggest design changes that it is ok too? i just need to make sure if user refresh the page the question need not be generated again and new quiz should not be registered to user.
