View 1 RepliesUI markup to create the table shown below, which I have mocked up quickly to visualise what I need to do. The data is in the form of custom objects; a SelectedSession object which has a List (Of Students) sorted by AcademicYear, TeachingSet, then name.
So the question is how do I create that table from my custom object?
<table class="style1">
<tr class="academicYear">

I've got a really good idea for a service I'd like to create for the web, but since I'm new to ASP.NET I'd like to get everything up and running before I go and buy hosting etc.
What I'm curious about is the database side of things.
I don't quite understand how I can create a datebase on my computer for the sake of testing and practicing (Presumably through mssql server) and then just transfer it to a hosting account when I'm ready.
I guess the main part I don't understand is how can I connect to a database on my computer via my application and then change the connection so that it points to the web version when I'm ready.
I know that when you create the database and include it in your project it's not technically inside your project (Right?), but it just seems that the application is very rigid once you've specified the connection.
On my local machine I have created a database driven website. All is working well on my local machine.
Now I want to upload it to my Arvixe Hosting. How do I do that from Visual Studio 2010 Keeping in mind I have a Database too ?
Do I need to manually create a Database on the Server ? Do I then create all the tables Manually ? Do I then populate the tables manually ? Or is it a 1 button click ?

I'm trying to design a map with co-ordinates that's driven from data in a database. I want it to look something like this:
Also, the selected X/Y co-ordinate must be centered for the user to see. How could I produce something like this?

I am using this article [URL] ....
But this article is in Horizontal Menu
I would like to ask about Vertical Menu like this [URL] ...
I m using this code
Menu menu = new Menu();
menu.MenuItemClick += new MenuEventHandler(menu_MenuItemClick);
menu.BackColor = System.Drawing.Color.AliceBlue;
But i want that background color of menu should be seprate two Different color red and AliceBlue

View 12 Repliesit will be very interesting that controls for input in forms have another property ie semanticid semanticname so semantically can be relationate i.e textboxes content if then we retrieve the data using linq having olap cubes we could have a lot of diferent views comunicating diferent controls of diferent webparts that shares the same semantically set or point to same ontology for the several dates or same localization from different input forms collection data,etc.
View 3 RepliesI want to change color of each row in a listview based on a data which is stored in database.
I've written following code but I don't know by the help of which object I can access to markup property of listview :
protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if(e.Item.ItemType == ListViewItemType.DataItem)
{
ListViewDataItem dataitem = (ListViewDataItem)e.Item;
int policyid = (int)DataBinder.Eval(dataitem.DataItem, "policyID");
if(policyid == 3)
//what should I write here to change the corresponding row's color?
}
}
I have a class (let's call it Car) that has a property of type System.Drawing.Color (Call it CarColor). I have a script service function that uses this Car class as a return value, which works just fine. I then have another script service function that takes a Car object as a parameter. I would like to change the color of the car in Javascript, but I am finding it difficult to do so without adding another parameter that takes in the color as a string and is then translated at the server. Are there any ideas on how to set the Color property of the Car object in Javascript and maintain it through to the server?

View 1 RepliesSo, after all and after all these projects that have been done. What is the best way and I should consider as standard in the furute to start any further ASP.NET Projects that are database driven.
I have done many using
1. Store procedures and classes
2. One class to handle all the add,delete,update ...etc functions
3. ADO.NET
4. Using sql statements directly on the code (I know not recommended, it was my first project) :))
..and so on
What method you recommend in the future that will save me code and errors and optimize my application speed as well.
The web app uses XML from a web service, which is then transformed to HTML using XSLT. The app uses a HttpModule to get the XML using AddOnPreRequestHandlerExecuteAsync.
Classes Used:
XmlDocument - stores the xml.
XslCompiledTransform - stores the transform, is cached in Application.
Asynchronous HttpWebRequest using BeginGetResponse/EndGetResponse
HttpModule with hooked AddOnPreRequestHandlerExecuteAsync events.
I do not want to use the XPathDocument unless there are no other possible optimizations. It would take some complicated code to get all the XML together without the ability to write to the XmlDocument. There is additional XML that does not come from the web service that must also be added to the document.
I am in the process of putting a new site together which will make use of AJAX to pull through page content should the user have javascript enabled.
So, I am in the situation whereby every Action Method requires a check to see if the request was through AJAX or not, which is straightforward. If the request was through AJAX then I can return a partialview, if not then a full view can be returned.
With this pattern though, I'll need to create a View and a PartialView for every page on the site. The only real difference between them is going to the inclusion of the masterpage.
Am I missing a trick here is is this doubling up of views the only way to go?
I had a page that could get accessed through /site/test. Somewhere in my JS I would add a hash to the url like so #/site/test. JS would then watch for any hash changes and load the partial views as needed. If JS was not available though, an entire view would need to be returned.
So for each page I would need the view, which would then include a call to RenderPartial which would load up the partial view which would actually contain the page content. So, for every page there are two files. It just seems there should be a cleaner way of doing this.
Assuming my application did not warrant a full blown DDD setup, would Repositories still be useful? I like the way they shield from implementation details (such as use of Entity Framework) underneath. However Repositories tend to be tied to Aggregate Roots (the concept is still a holy grail to me) by definition.
I suppose the question could also be put as such: if I have a typical 3-tier application, with a business layer facade consisting of "logical grouping" classes based on functionality (rather than aggregate roots as in DDD) such as TradingManager and ContactsManager, would it make sense to also create "logical grouping" repositories. Or perhaps a Data Access Object, which I believe is like a Repository without the aggregate root requirement. Of course I will still have a Model (EF POCOs) that will be passed up and down between the layers.
Also, is what I just described would be considered as a Transaction Script approach? It's certainly not DDD, and not Active Record. I'm not even sure if Active Record exists with EF4 like it does with Nhibernate.
I am trying to understand how others structure n-layered applications when they do not follow DDD.
I'm doing some asp.net mvc coding using DDD. I have objects representing the business entities and service repositories that handle fetching and adding them. I'm new to this and as my application grows I begin to see a lot of secondary code that must run as a result of adding, deleting or changing my domain objects/data.
I'd like to make an event driven system where one action triggers other parts of code to run. For instance when I delete a user I want to be able to subscribe a number of other things to this action so they all are run when a delete takes place.
How have you coded your applications to handle these situations? How can I establish a reliable and coherent OO system for my problem? I already know about events and delegates but I'm more interested in coding techniques and nice practices.
I have several tables in a database (6-7 tables and ~200,000 records, MS SQL) that I'd like users to be able to use a web based query form and return information/datagrid/download csv/excel files. I'd like the user to be able to query the table they want and fields they want, time they want (maybe datepicker)or by selecting a field and perform a GT/LT operation on it. Has anyone done this and if so are there any resources/templates for this type of thing?Here is an example:I have a 'weather' table with 20 variables in it. I'd like a user to be able to select the fields they want to export (radio/check box) by using a date picker A user could select the variable "Temperature" and use GT/LT, etc. some value they enter. in a perfect world, the user could select a checkbox to include all other fields in the output.
