I have a situation where I need to maintain a large number of related integer values in my ASP.Net 3.5 application. The SortedList seems perfect for this purpose. If this were a Windows app I'd just create a class and setup one method to Set values within the SortedList and another one to Get values out of it.
But being a web app, I'm not entirely sure of the best approach to use. Sure, I could just create one method for Set and another for Get but that doesn't seem very "clean".I thought about creating a UserControl without any visual elements but am not sure if that makes sense.How would you go about implementing such a SortedList in your web app?
I am looking to implement a Wizard for my Web Form, please could somebody give me suggestions as to which approach would be best jQuery or ASP.NET Wizard control? give links describing the implementation, if possible.
I have a gridview that takes in values from a sortedlist. I want to filter those values before putting them in the gridview without taking values out of the list.
Is there an easy way to do this? Or do I have to redirect the data through another list and point the gridview to it?
I'm new to Asp.net, and I looked at an example of using a listbox's selected index to delete from a sortedlist. I'd like to write somethingthat would get the selected index from a different control, like a listview, and then delete from the sortedlist. I've read up on a few examples on how to bind data from a sortedlist to a listview, but I've not seen an example of how to get the index once the data is displayed! Can this be done?
i have a sortedlist who values contain a Product objects. i wish to set the Quantity property of a selected Product object ( from gridview) when the Quantity field changes?
how do i compare whether the product row Quantity field in the gridview is the same as the Product Quantity property in the sortedlist and update accordingly?
note. i have converted to a list(of product) to bind to gridview. then update the sortedlist values
Could someone give me a small example how i can make reusable WebUserControl (.ascx) file.Basically i need to make a employee lookup utility where users enters employee id to get Emplyee information.Once the Emplyee information is available, it is used in various data entry tasks by the page that includes the control.
I'm trying to create reusable "zones" but am having trouble figuring out how to give them all unique ids.What I'd like is to be able to create a component which can be put on an mvc page using the usercontrol syntax or using RenderAction or RenderPartial. I want to be able to update these components' content using ajax, so I need someway to reference them by id. However, there is no mechanism in MVC that wraps anything in a div or something like that.
I've learned that if I extend ViewUserControl and put the controls on the page like so:
[Code]....
This way, I can pass the previous ID and put it in ViewData, in case I need it laterThen, I can even go through all my controls on page load event in the master page and get my unique ID and write somekind of register javascript function to the page so that I can do javascript stuff if I want when the page loads.
[Code]....
Is there a more elegant way to do this? I see similar stuff from 'Areas' but never seen an example where someone has put more than one area on a page and then needed to reference them via javascript. This also seems similar to custom templates, but I'm having trouble figuring out how that would work.
I want have a web application that I am putting together - but I have started to see that some of the things I am writing are repeated over and over, example -
GetDepartments() in the code behind has all the database connections and is linked to a stored procedure.All it does is return Department Names' and Ids', ie then bind them to a dropdownlist.My question is this I have seen Class files - I want to know if I can put this type of information in there and just call it whereever I need it in the site and then bind to whichever dropdownlist I need to?I have had a look around the net and even saw some examples by scott mitchell - but it used datasets (.xsd) files etc and dont want to be using them, plus it was a little over my head. Does anyone know of some good simple examples out there that I can follow, or maybe some examples on here?
I have been given the task to create a TAB control ( probably the Jquery tab control) as the company wants the Lazy loading of data.
The tab control should not have fixed items on it. It should be reusable in different projects . So I cannot fix the items in the tab control. Depending upon the project the tabs can change.
Need some great ideas on how I can achieve it.
Note: I am using MVC, VS 2008, C# for my development.
I am trying to write a simple library for MVC2 projects that takes care of user login, e-mail validation, password recovery, logging, etc. Since some of these steps involve user interaction, I need to have Views and Controllers in that project.In MVC2 Preview 2, one could do this by abusing areas (at least, it seems) since they were implemented as different projects. However, in the RC, creating a new area will merely create a subfolder. Since I want to share the base code between applications, that is not an option.I tried to brutally hack the AfterBuild steps into my project files, but that feels like the craziest hack ever.
I want to build a reusable library of User Controls.
I found this article:
[URL]
While it works for me, but I find it a bit cumbersome to implement, expecially for future maintenance.Also, I noticed that if you create the User Control with code in separate file, it will not work. In this case, you will not get any error, but, the page where the control in registerted will not show (you will get blank page).Why I am getting BLANK result when I develop the User Control with code in separate file ?I appreciate your recommendation on the best approach to implement a library of Reusable User Controls. Also, I did not like the method of Web Controls, becuase they are difficult to implement.
I want to build a reusable control which will enable e to perform add/edit/delete operations easily. All I want to do is give the control a datasource and it will handle the rest.
What controls should I use? I want it to be as user friendly as possible.
In .NET land what would be a good approach for quick prototyping of a concept (i.e. development just on my PC) that could then be extended out to product (users across LAN/WAN), BUT in a fashion that the model/business logic code and data access layer code can be used as is? One thought for example I had as to do: (a) WinForms with business logic and Entity Framework layer to SQL Server Express on my PC, then (b) Go then to ASP.net (using the business logic / data library) with SQL Server/IIS
I need to have a section in my website dedicated to viewing and printing reports.I've created a Reports Table (ReportID, ReportTitle, ReportDescription, ReportCategoryID), so I can display a list of Reports on a page.I also have a ReportCategory Table (ReportCategoryID, CategaoryName, Active).So i could have all the categories in a dropdown perhaps(not sure it's the best option)
Then once a selection is made I can display the reports under that category.Clicking on any of them will then display the report or save it to disk.My question is, should I create a Reports Class? if so, can I get a few pointers
I have implemented AJAX for calling server side function using client side function call i.e Calling server side function using javascript tag by using PageMethod in javascript.
I have few question regarding the same implementation.
[code]....
This FunctionName will be the name of server side function that a developer want to call.
I'm working to move my simple asp.net website to a three layer architecture. Currently I have Linq queries like the one below in my code-behind files. Basically this code snippet retrieves a collection of customer data from the database and then binds it to a grid control.
I'm wondering if someone can guide me on how to rewrite this in order to move it to my newly-created data access layer. I'm thinking I will turn it into a class (e.g. GetUserBoxesByStatus()) that can be reused throughout the site.
var boxes = from p in sbm.Packages where p.UserID == CurrentUserId && p.StatusID > 1 && p.StatusID < 3 select new { p.PackageTag, p.PackageName, p.DateReceived, p.DateShipped }; [code]....
Some of the options that I've investigated but have not had success implementing are the following:
DataTable --- returning a DataTable seems like the best solution but it also appears to require a lot of potentially unecessarry code to define a table (isn't the data source already mapped in my Linq 2 Entities dbml?)
IEneuerable --- I think I could pass an IEnumerable list between the layers but after reading many tutorials about Linq I'm still a little lost DTO --- Conceptually I think I understand what a DTO is but I am not clear on how to begin implementing this approach POCO --- Again, the concept seems logical enough but I don't know how to put this into practice
how they would tackle this using one of the above or some other solution.
I want to create a reusable user control which contains a date time picker in asp.net. Need to add this user control in a grid view as column.While clicking the column,date time picker has to be displayed.Which is the suitable method,Creating the component or creating the user control. Also want to know, How to add this component in to the toolbox?
What is the best approach to one to many relationships?
This is my scenario:
I have a simple one to many relation:
Customer CustomerID Name tel CustomerNotes Id Note customerID
I want to have a DETAIL view of customers and CREATE view for CustomerNotes all in the same page.
I create CustomerController and the different views and its respective actions for edit, create, delete, etc.
I also create a CustomerNotesController and the views and actions like before, but I made the views PARTIALS
I put a RENDERPARTIAL for the CustomerNotes create view in the Details view from Customer.
When I run the app, the page is render as expected: It shows the detail info of the customer and bellow the create form for the notes. However, when I click SAVE, nothing happens. I put a breakpoint in the notes controller and never get hit.
I also try with RenderAction and don't work at all.
I've been reading up on DDD a little bit, and I am confused how this would fit in when using an ORM like NHibernate. Right now I have a .NET MVC application with fairly "fat" controllers, and I'm trying to figure out how best to fix that. Moving this business logic into the model layer would be the best way to do this, but I am unsure how one would do that.
My application is set up so that NHibernate's session is managed by an HttpModule (gets session / transaction out of my way), which is used by repositories that return the entity objects (Think S#arp arch... turns out a really duplicated a lot of their functionality in this). These repositories are used by DataServices, which right now are just wrappers around the Repositories (one-to-one mapping between them, e.g. UserDataService takes a UserRepository, or actually a Repository). These DataServices right now only ensure that data annotations decorating the entity classes are checked when saving / updating.
In this way, my entities are really just data objects, but do not contain any real logic. While I could put some things in the entity classes (e.g. an "Approve" method), when that action needs to do something like sending an e-mail, or touching other non-related objects, or, for instance, checking to see if there are any users that have the same e-mail before approving, etc., then the entity would need access to other repositories, etc. Injecting these with an IoC wouldn't work with NHibernate, so you'd have to use a factory pattern I'm assuming to get these. I don't see how you would mock those in tests though......................
I am looking into the possibility of shortening / encrypting a url which will be from 150 to 250 characters in length to maximum 12 characters using an algorithm. Initially I am doubting it's possible but I wanted to leverage the great minds of StackOverflow :)
the algorithm should be one that can be written in classic asp, sql, c#, vb, or foxpro or other language.
Is that even possible without a database centric approach?
I was reading here that AES in CFB mode, will do a stream cipher and the output length will be the same as the input length. Is there any way to shorten it even more?
