I usually use STATIC implementation when developing Desktop Application and I just got my head bumped on the wall when I use STATIC in ASP.NET (not a good idea)I think I saw some feedback here before that you can use INTERFACE for passing values between Classes and Pages without using Session.here's my sample code
public interface ISessionManager
{
SessionStates sesState { get; set; }[code]....
I have been founding an effiecent way to retreive values returned by LINQ 2 SQL stored procdure on my presentaion layer. Am using following method rightnow:-
public List<String> MthInvitesBA()
{
List<String> lst = new List<string> { "" };
ISingleResult<USP_Actor_View_InvitesDetails1Result> invites = obj.USP_Actor_View_InvitesDetails1(p_UserName);
foreach (USP_Actor_View_InvitesDetails1Result c in invites)
{
lst = new List<string> { c.Invites_Used.ToString(), c.NoOfDoc.ToString(), c.Request_For_More_Invites.ToString() };
return lst;
}
return lst;
}
It works but at the cost of my performence due boxing unboxing on BA layer as well as on design layer. Now, I have one method which returns me 100 columns from table So in this way i have convert 100 coulmns value into type string then On design layer again have to type caste some values .Moreover, i could only access this list using index which is of type integer, which is very diffcult and tedious task to debug d code. i could effiecenlt retreive these values. Is it possible using IEnumerable? How to access Ienuemerable in design layer?
I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?
I am learning how to work with BLL and DAL
I have 2 class files in BLL and using DAL i am connecting to the sql database
in BLL i have a class called productsHelper.cs and using GetProducts() method used to fetch records from database
products.cs - have all insert,edit,delete methods
I want to bind all products to gridview
But I couldnt find how to do that.how to get those methods to my aspx.cs page from class files.and write code in there.
I have two different classes, and would like to (for example) alter the text of a label control contained in one class using the other. At present I experience the following error (e.g.):
"ProjectName.PageName.Protected WithEvents ControlName As System.Web.UI.HtmlControls.HtmlGenericControl' is not accessible in this context because it is 'Protected'."
All the subroutines in my PageName class begin "Protected Sub...", however even if I change these to "Public Sub..." this does not fix the problem. How do I achieve this? Also, are there security implications to not protecting subroutines?
I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?
I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).
I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.

I have a web page that contains a GridView which the user is allowed to "Edit", "Delete" and "Select" rows. What I'm trying to accomplish is when a user clicks on "Edit", they are redirected to another web page that contains a DetailsView of the record they selected from the GridView (previous page). How do I make the association?

View 2 Repliesi need to pass a long list of Ids from one page to another, i was thinking of using querystring but taking in consideration that the number of ids to be passed may reach 300 i think is not a good idea.an option from my understanding may be the use of session, this seems to me an optimal solution in my case but on the other hand I can certainly clear the session when the user performs a certain action and the list of ids is not longer needed, but if the user leaves the page without performing any action i want to clear the session, how can i do it?f multiple users are using the same functionality do i need the session's items to be confused or the session is for a single user?

Please let me know.

View 9 RepliesI'm only a newcomer to ASP.NET MVC and am not sure how to achieve a certain task the "right way".
Essentially, I store the logged in userId in HttpContext.User.Identity and have written an EnhancedAuthorizeAttribute to perform some custom authorization.
In the overriden OnAuthorization method, my domain model hits the database to ensure the current user id can access the passed in routeValue "BatchCode". The prototype is:
ReviewGroup GetReviewGroupFromBatchCode(string batchCode);
It will return null if the user can't access the ReviewGroup and the OnAuthorization then denies access.
Now, I know the decorated action method will only get executed if OnAuthorization passes, but I don't want to hit the database a second time to get the ReviewGroup again.
I am thinking of storing the ReviewGroup in HttpContext.Items["reviewGroup"] and accessing this from the controller at the moment.
