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 ?

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 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.
If not what are alternatives in asp.net mvc to make reusable components? Which of those alternative is recommended to use?
View 1 RepliesIn classic ASP I would write some logic to get a nice menu on the site, but now with the Menu-control, it's as easy as it gets.. Maybe to easy. I can't quite figure out how I would do this.. I have a multilevel navigation structure (from a database) that I want to put into the Menu-control, but I don't know which approach is the best/easiest way for me..
I'm all into performance, usability and all that.. The only thing I have really decided is that I want to use the Menu-control, I haven't decided what datasource I should use or how to style the individual links my way The data is coming from a database and is not supposed to be changed very often (maybe once or twice every month).. Thought of making an XML-sitemap, but also of making some sort of SQL-hookup.. I'm leaning towards the XML-sitemap because it wouldn't take long to generate the XML every time the navigation changes and that won't happen very often. The next issue is styling, how to do that? I have the neccesary css ready for the individual links, but I'm still unsure of how to get it to the Menu-control.. The css I have looks like below and in its current form is intended just for the anchors

View 1 RepliesIm trying to incorporate the ajax controll toolkit slider control within an ascx control so that i can then use that within a repeater on an aspx page. Basically i want to have a number of slider controls rendered to a page with default values based on data from a database. i need to put the slider within a data bound repeater as i wont know until runtime how many sliders i will need (maybe there is a better way?). does anyone know of ay examples of how to do this?
The user will then need to be able to move the slider to the value they are after and on the mouse up event ie when they release the slder I will want to be able to update my database with the value they set it to. This bit i think i am ok with but i cant seem to work out how to build a page where by i can render lots of slider controls wth default valuesset from a database.
I have a data driven site that displays a lot of information, particularly images, using listviews contained within UpdatePanels, since this data can change with each post back you often see 'submit query' before the Item image appears. So, is there a way of making the page display only after it has finished loading data? The delay as the page loads is only brief but looks quite ugly when 'Submit query' appears all over the site.

how to use <href> tag in asp.net Menu Control?? i have to open pop up pages.
View 1 RepliesI started a new project using VS2010. I have a menu control connected with an XML datasource inside UpdatePanel, Menu control works fine, problem is the styling. using a StaticHoverStyle Css works only after the page reloads, when I click a menu entry, the entry is selected but StaticHoverStyle does not reflects the menu items anymore (of course when I hover the items) Same behave with both Net versions 3.5 and 4. When I remove the UpdatePanel the StaticHoverStyle comes back to life ( post back occurs ).
View 1 RepliesI'm using the new version of ajax control toolit - 40412. Installed it due to the previous version having problems with modal popup extenders inside update panels. I Installed the new version and found it worked fine as soon as I change my scripmanager to ToolkitScriptManager, However, I recentlly realised that now my sites hovermenus do not work in IIS6 (maybe 7 too) Ive tried in firefox and IE and the same. I changed from <asp:ToolkitScriptManager> to the old <asp:ScriptManager> and they work but I need the toolkitScriptManager cause of some new controls I have used will use need it. This is all implmented in my masterPage for the site so I will post the code (there is nothing in the code behind)
[Code]....
It all runs fine when I run as project from Visual Studio.
I'm creating a user control to be placed within a masterpage on a site. Inside the user control, I have placed a menu. It is wired up to a sitemap datasource to get navigation with security trimming included. question: How do I use the Accordion toolkit control to collapse main portions of the menu? For example, if I have Orders and Supplies and subpages contained therein, how do I setup Accordion to traverse the sitemap based on the user's security privileges?
