View 2 RepliesUnderstand Polymorphism When Using Generics In C#?
Aug 25, 2010I am having a problem understanding how polymorphism works when using generics. As an example, I have defined the following program:
public interface IMyInterface
{
void MyMethod();
}.....
So, at least I haven't completely misunderstood that. I am unsure exactly how I am to write a method that accepts a generic collection of classes that conform to the same interface.
I have a plan to completely hack around this problem if need be, but I would really prefer to do it properly.

View 1 RepliesUnderstand JS Execution On Onclick Event Of Button
May 28, 2010<input type="button" name="reset"
onclick="return ValidateValue(); __doPostBack('ApplyBtn','')" />
The above is the code generated for asp server button button control on browser. Now my query is that irrespective of ValidateValue() returning true/false __doPostBack('ApplyBtn','') function is not showing any effect for me. My understanding is that string passed to onclick acts like function body, and return will from first function will return control preventing second function from execution.
Is that correct?

C# - Rootlevel HTTP Module - Unable To Understand The Master Page Path In The Virtual Directory
Mar 1, 2011I have a http module at root level which resolves to the virtual directory which is a .net application on some conditions as below.
I need the have the httpmodule at root level only for some requirements.
application.Context.RewritePath("/virtualdirecotry/root/pages/sample/sample.aspx", String.Empty, "");
the sample.aspx page uses a master page as below
<%@ Page Language="C#" MasterPageFile="~/Root/Pages/Master/Site.Master"
as it uses the relative path the http module is unable to understand the path and throwing following error
The file '/Root/Pages/Master/Site.Master' does not exist.
error occurred during the parsing of a resource required to service this request. review the following specific parse error details and modify your source file appropriately.
Visual Studio :: Unable To Understand The "build Deployment Package" In VS 2010
Jul 22, 2010I don't understand how to use this feature called "Build deployment package" in VS 2010. I go to my properties and go to package/publish web and setup it up. I click "Create deployment package as zip"
I then build the deployment package and get a zip file.
When I look into and start drilling down in the folders I find I get a path like this
[Code]....
I don't understand why it makes all these folders and on top of it why is it my path to where my soultion sits. I don't like the fact that now everyone can look in the zip and see my accoutn name, where the file was sitting, that I am using subversion.
Then it makes it so confusing to when a error happens. I deployed it on my IIS windows 2008 server and ran it and I had a error show up. It pointed to the file where the error occured and the path was point to my desktop.For the longest time I could not understand why it was pointing to my windows 7 machine desktop when it was running on a windows 2008 server located in a different country.
It was not until I found out with the zip path it made sense. But that is confusing when it is pointing to paths that don't exist on that computer.
How can I change this?
Forms Data Controls :: Way To Understand Data Grid Control
Jul 21, 2010When the data grid connects to a sqldatasource control and displays say 10 records with 5 pages from a total of 50 - has the application downloaded all 50 records or only the 10 on page 1? Is that why I use code to get the data and then implement paging myself or does the application know the 50 records are downloaded and when you click to the next page it works locally?

C# - Unable To Understand "A Field Initializer Cannot Reference The Nonstatic Field" Error?
Mar 29, 2010I am getting the error "A field initializer cannot reference the nonstatic field", While My code is as below:
Object selectedItem = PageVariables.slectedItemData;
MyClass selectedItems = (MyClass)selectedItem;
But the same thing works if assign the value at the constructor or in a different method , like below:
public partial class MusicPlayer : Page
{
Object selectedItem = PageVariables.slectedItemData;
[code]...
I am just trying to understand what is the difference, Why it is looking for a static varaible declaration(in 1st case) while doesn't look for it while in a constructor or a different method
