View 2 RepliesI'm looking to implement a membership system using OpenID for my ASP.NET application, similar to the system used here on StackOverflow. I'm aware that the OpenAuth library is generally recognized as the way to go, but I'm having trouble figuring out how to implement it.
I use NHibernate to persist my domain objects. I have a Users table with a username column, email column, etc. I'm not sure how to integrate OpenID with my own users table, and I haven't found any good tutorials on this. Does anyone have any experience with this? What is the best way to go about doing it?

I was wondering if setting a default value for a SelectList is considered to be presentation logic or business logic? For example, if a requirement is that an Employee cannot be saved without a Location, but 99% of the time the location that would be selected is a particular item -- say Atlanta. Because of this, the location SelectList should be defaulted to Atlanta when ever a entry screen for a new employee is displayed. Should I be defaulting the location in the model or in the view-model? One thing I realized is that the unit tests become awkward because in both cases, I'd be forced to test against a location that will always be present in production but I cannot create a unit test with my own test dataunless "Atlanta" was in the set of locations being used in the test.

View 3 RepliesIm about to create a very simple online event reservation application and currently have 3 tables:
User
PK_UserID
UserName
Event
PK_EventID
EventName
EventDescription
EventStartDate
EventEndDate
SeatsAvailable
BookedEvents
ID
FK_UserID
FK_EventID
Do you have any experience of how to handle SeatsAvailable? I mean if SeatsAvailable is set to 5 and there are 5 users online and want to book event. And some user has started to fill out the form then changed his mind. Then seats in database can just leak. I was thinking about sessions - like to limit every user to 5 minutes to complete the booking but i dont really know.

View 2 RepliesI have a RadioButtonList control, containing two ListItems. These two Radio Buttons toggle each other, so that only one is selected at a time. When the second is selected, it affects whether a Textbox is enabled or not, and also erases the text in the Textbox when selected. Lastly, a Button is present to execute the selections made.
I have a RequiredFieldValidator and a RegularExpressionValidator on the Textbox, since when the first Radio Button is selected, I need to validate the entry. However, I need to turn off the functionality of the Validator controls when the second Radio Button is selected.
I have a bounded dropdownlist. there may be many items in dropdownlist, i dont know how manty they will be depending on some conditions.suppose there are N items are bounded in this dropdownlist let say

I have a very simple datalist setup to a SQLDatasource. Displaying the data works great. But I want to replace the plain databinder container with a hyperlink instead and have that link setup to point to a detail page with a parameter. Here is my datalist setup:
[Code]....
On another page im using gridviews adn able to do what i need by using the RowDataBound of the gridview like so, how can I accomplish the same thing with a datalist?
[Code]....
I tried using the ItemDataBound and trying to modify the logic above to fit the datalist, but cant figure out how to, so I have it commented out at the moment.
[Code]....
I have the below code that works for an asp.net repeater but I need to convert the logic so it works for an asp.net listview control...possible? Unfortunately, the same code throws errors when placed within my listview's itemdatabound event.

I know there are a few posts on this issue already, however I haven't found the answers I was really looking for.
My situation is like this: I have a DLL project containing my business logic. Then I have a web application that refers to this DLL, and calls a function from it. And I have a global.asax which handles errors on Application_Error
Sample:
// MyWebsite.aspx.cs
using MyBusinessLogic;
protected void Page_Load(object sender, EventArgs e)
{
MyBusinessLogicClass.DoSomething();
}
// global.asax.cs
protected void Application_Error(object sender, EventArgs e)

I have a sidebar on a page with vertical navigation about products The navigation links are created from an xml sitemap with a repeater control using 2-level nodes with product main categories and subcategories I want to display the data so when i click on a main category the page will reload showing the underlying subcategories names and description in the main section (div) of the page, but also when i click a subcategory's name from the sidebar, i will get its products (names and description from an SqlDataSource) in the main section. (In the main section i'm probably going to use a DataList)
Can i do that ? Display different category level data depending on the link that was clicked or do i need a seperate "maincategories" page. The scenario is similar to the master-pages-and-site-navigation tutorial in the data-access tutorials but that one goes as far as presenting the main categories [URL]
I've been looking at implementing Url Re-Writing into my site, and have been confused by the sheer magnitude of different methods of doing it!
Anyway, what I'd like to do is convert my existing url into something more readable and search- engine friendly.
For example, my current Url is '~/Magician?localityId=x' (where x = the id of a place name)
and I'd like it to be '~/placename-Magician' (where placename = that retrieved from the querystring)
I use the localityId to query the database with, in order to get the relevant place name.
Does anybody know the best method to use for this, and can you point me in the direction of a good tutorial for that method?
I'm working on a project that involves exporting HTML to PDF. I was told that this can be accomplished with a a free library called ITextSharp:http://itextsharp.sourceforge.net/This looks like it's actually a JAVA-based interface. Does anyone know how to actually inistall this and reference these dlls in your ASP.Net project? Maybe there there's a different version of ITextSharp for .Net that I missed...

I have included a flash menu inside the master page. The menu is embeded in the masterpage as an object using <embed> tag.
I have given the link of the menu items as main.aspx?q=Electonics
or main.aspx?q=computers
etc.
What i am trying to do is.. that when a user will click over a menu item, he will be directed to menu.aspx and depending on the value of q I will change the content of the webform dynamically.
Eg: If he clicks over the item corresponding to main.aspx?q=computers , then he will be directed to main.aspx but the content will be related to computers
similarly if he clicks over main.aspx?q=electronics ,then he will be directed to main.aspx but the content will be related to electronics
But i m facing problem implementing this concept.
I have a listivew that is assigned a datasource in the code behind based on query string options. From what i have found out, once there is no datasource assigned in listview html then the sort feature stops working automatically and you must put the code in the _Sorting event. I cannot find a good example of this logic.
good example of the listview manual sort logic?

I am having issues implementing SqlSiteMapProvider using the Wicked Code article. I am using VB.NET and SQL Server 2008 - and the OnSiteMapChanged event is not firing (the SqlDepdencyCache just seems to simply be not working at all). The article states "You also need to run the ASP.NET worker process with dbo privileges for SQL Server 2005 cache dependencies to work automatically.)" I don't understand what this means. I know what the ASPNET user account is and that it runs aspnet_wp.exe which is basically the ASP.NET run time as I understand it. I know what DBO privs are on SQL. But my SQL and web servers are on different machines, and ASPNET is not a domain account. And it seems crazy to make it one to try to simply get the SqlDepdencyCache to work, and I have trouble believing everyone is doing this?Anyone have any clue what I'm missing here?
