how do i write a async class like WebClient? Is there anyway i can keep it short and does not have to repeat it for every method?
for example, i have:
Download(string a)
Download(string a, string b)
do i have to rewrite Async + Complete method for each of these?
I have a code which saves the control id and its text in database..(and it is working fine).This code is written in default.aspx.cs which will save all the controls(of deault.aspx) id and name in database.I want to make a class file and then call this class file in page rather than writing the code in page because there will be multiple pages where this can be called.write this function DisplyDetails() in class file..code is as below..
public partial class _Default : System.Web.UI.Page
{
string controlId, propertyValue,other;
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["abc"].ConnectionString);
protected void Page_Load(object sender, EventArgs e)

I'm having problems drawing the lines on what code goes where in the following case. What goes in the View, Controller and Model. It should be noted that this is my first MVC project.So I'm building a bilingual site where the user may select either English or Norwegian language. I want the user to be able to choose language with a link at the top of the page. The link for the selected language at any time is emphasized with a certain CSS class.
The user setting with the selected language at any time is stored in a cookie at the client. When a request is done, the cookie is parsed and the settings are objectified as a part of the Model the way I've implemented it as of now (please object if you find this weird, but this is not the main focus of this post). I.e. a super-class which all my models inherit from, has the UserSettings class with the Language property.Now, where do I write the code which translates the language property into a CSS class?Option A, the View: I envision some code which interprets the language and output one of two possible lines of code based on this. We'll have IF's in the View.
Option B, the Controller: Logic in the Action method sets a ViewData-property with the name of the CSS class for both the link to the Norwegian and the English language.
Option C, the Model: I create a new property in the Model doing the same thing as the code in Option B. Except now I get strongly-typed parameters in the View and intellisense. (But I do suspect you guys will not like this solution for separation-of-concerns-reasons)
Option D, the ViewModel* I create a new class which is a ViewModel for the Model with the same property as in Option C. Now I get better separation of concerns.Yes I know there's no ViewModel in MVC, but I also know some people implement it anyway.
So what do you say? A,B,C or D? Or maybe you've got an E?

i have the following code repeated in many pages in some cases only the sql query chnages instead of repeating all code lines in each and everypage

I have a table which stores steps in a process. Some companies only have 6 steps while others have 15, so I created a table with 15 different slots for steps. What I would like to do is set up a control that displays each step in its own row with a label next to it saying "Step '#'", and not in an adjacent column. I'd also like for it to not display any blank rows. If they are entering the step instructions, I would want for them to have to press a button that would add a row so that they aren't just given 15 empty text boxes to fill in.
What would be the best control to do this in, and how would I get started in setting it up?
I have this sample code for async operations (copied from the interwebs)
[Code]....
Other async approaches I tried required the aysnc page attribute, they also seemed to cancel if other page elements where actioned on (a button clicked), this approach just seemed to work.
I'd like to add a cancel ability and exception handling for the longRunningTask class, but don't erm, really know how.
I'm trying to find the best server architecture solution to deploy monthly updates to an Asp.net external public facing website. What I'm looking for are ways to release a new version of a website with minimal impact to users. Besides deploying the standard way (ie. stop IIS, copy new website over existing website, start IIS), what are some "better" solutions for deployment out there? It would be nice if they kept their session and didn't have to see a "Website under maintenance" message during the update. My server configuration
We have 2 IIS web servers (2003) and are trying to figure out the best way to utilize them for deployments. My first thought was to update the non-active web server with the latest release. Then to gracefully point the web traffic to that server with minimal impact to users (best case, the user doesn't lose his session). How would you go about "repointing" the web traffic from server 1 to server 2? Changing firewall NAT? Changing DNS records? Some other way?? We need to be able to test the live site immediately after we release the new changes (duh). BTW, we are using nant and cruise control to automate the builds, and a custom web service to deploy the build to production. So it's all automated with the click of a button. Could a better solution be achieved using a 3rd server? If so how?

I'm storing a token in a session variable. I launch a report that needs this token in a new ASPX page by using the javascript windows.open function. When this new page loads the HttpContext.Current.Session is null.I have gotten around this by passing the token in the query string but activity in this window needs to keep the session of the parent window active and I'm not sure what the session object being null means for this scenario.

I have a class (name PageBase) that is inhariting System .Web.UI .Page and all my .aspx page behind classes are inhariting this class. This way I have put some common things in PageBase class.
For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.
Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .
I dont want to pass control as argument to function in parent class, is ther any other way ?

View 3 RepliesI'm new to C# and ASP and can't seem to figure out how to write a function to return a CSS Class name.
Here's what I have so far:
In "MyWeb.master" I have a line that reads:
<asp:HyperLink ID="HyperLink1" text="xxxxx"
cssClass='<%# MyCssStyle("ddd") %>'
NavigateUrl="http://www.RDRR.com/Catalog.aspx?TribeID=1"
runat="server" />
And in "MyWeb.master.cs" I have a routine within the partial class that reads:
public string MyCssStyle(string myInput)
{
myInput = "NavigationBarUnselected";
return myInput;
}
This code does not throw an error, but neither does it return a value. What have I missed?
In my Code Behind I use several times this code below to bind and rebind (for refresh) e GridView after an insertion or other operations completed using EF objects.
Using a simple gridview.DataBind(); does not work because I call EF programmatically so I thought to use a Class to keep in memory this code that can create Objects for my GridView and call it how many time I need in my code avoiding redundancy.
IEnumerable<CmsContent> queryContents = myCurrentSlot.CmsContents.Where(x => x.IsPublished == true);
uxManageContents.DataSource = queryContents;
uxManageContents.DataBind();
Or do you know a batter way to Refresh the gridview after EF executing some commands? how to do it?
remember that I do use any data source web control for the gridview but i bind it programmatically.
