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.
I'm developing an asp.net web applcition that works with sql server. i'm using Entity model as DAL.I user repository pattern for my business layer, now, i'm going to design UI.this is my business layer code:
[Code]....
I have some questions: becase all of entites need to have CRUD operations, so i want to have a master page with Insert, Edit, Deleter Button and a place holder for entity form, so for each entity i create a form with this master and create textboxes and label in asp:content tag.for this to be done i konw master must have a Interface to do operations. so i wanted to define ISchoolSystemRepository<??> as a property in master page, but i must pass it T which will determined in runtime. so
1.how i do this?
2. is this approach right design
I only need one textbox inside gridview and other operational buttons like add , edit , delete in gridview. I just need that these buttons can save the data in datatable like we do :
DataTable dt = new Datatable();
I don't want to save it in database at this stage. CRUD Operations using datatable inside gridview is my aim.

View 2 RepliesI 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 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.
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.
View 1 RepliesIn ASP.NET web forms we created few user controls (.ascx) which were used in almost all of the projects. I'm not sure how to achieve same in the MVC?
View 2 RepliesI'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.
How can I use Microsoft Access as a database in ASP.NET website? Is it possible?
View 4 RepliesI 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 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 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.
View 10 RepliesI 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.
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
Say you have a for loop which renders a bunch of the exact same control. This is probably done with RenderAction or RenderPartial.
What is a way to ensure that each of these controls in the list gets wrapped in a div with a unique ID?
is there a way of specifying a template to be used when VS generates the HTML, when we:
1. Right click, Add New View
2. Select Create a Strong Type View & Select Model class.
2. Select Edit, Create, List, Details etc...
E.g.
When we create a Details view, each field and corresponding data from the Model is wrapped in <p> tags, I always have to manually edit this html after it has been generated.
It would be nice to specify a template or define the tags we want to wrap this data.
Can this be done?
i have following entities as you see BudgetPost has a composite primary key which is a foreign keys to entities Category and Budget. My question is what is the best way to make CRUD? Is there any way to mapp the foreign keys? The simple insert should look like this:
Budget newBudget = new Budget();
newBudget.BudgetName = textBox1.Text;
newBudget.FromDate = dateTimePicker1.Value;
newBudget.ToDate = dateTimePicker2.Value;
newBudget.BudgetPosts.Add(new BudgetPost { FKBudgetID = newBudget.BudgetID, FKCategoryID = 21, BudgetAmount = 700 });
db.AddToBudgets(newBudget);
db.SaveChanges();
i have a database with many tables. I want to implement add/update/delete functionality on each of them Is there any tool available which will build the webpages for each table with add/update/delete functionality.
View 7 RepliesHow to write a stored procedure for a crud application in asp.net?
send me which is easily understandable...
I am looking for an accepted pattern for using MVC 2 and EF. Especially I am interested on how to implement updates. Where should the ObjectContext be created, where should the queries be, how to pass a model object from the controller and have it persisted with minimum robust code. I also want to be able to use transactions when updating multiple objects.
I used Linq in an asp.net application (code behind model). With EF I was hearing it was much more n-tier friendly, but I don't find it any different, rather than people talking about POCO which to me, all it means is satisfying the desire of those that want to have control of every piece of code being created.
If I want limit certain users or user_groups to - create a packing list (which consist of number of items and quantity)and then the creator of the packing list can select users / user_groiups to have right to- read a packing list- update a packing list - delete packing listsCan this be done by a custom made RoleProvider ? How best to implement the authorization ?
