Hi,
I have a gridview. in run time i need to drag the value from one cell of gridview and drop it in another cell of same gridview in asp.net website.
help do the need full.
Inherited properties and MetadataType does not seem to work with client side validation in ASP.NET MVC 2.
The validation of our MetadataTypes work as expected on the server but for some reason it does not generate the appropriate client scripts for it. Client side validation kicks in as expected for properties with the DataAnnotations attributes set on the PersonView so I know that client side validation is active and that it works. Does anyone know if or how it can be fixed?
Here's what we have:
public abstract class PersonView
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
[Required] public string PhoneNumber { get; set; }
public string AddressLine1 { get; set; }
public string AddressLine2 { get; set; }
public string AddressZipCode { get; set; }
public string AddressCity { get; set; }
public string AddressCountry { get; set; }
}
[MetadataType(typeof(CustomerViewMetaData))]
public class CustomerView : PersonView {}
[MetadataType(typeof(GuestViewMetaData))]
public class GuestView : PersonView {}
public class GuestViewMetaData
{
[Required(ErrorMessage = "The guests firstname is required")] public string FirstName { get; set; }
[Required(ErrorMessage = "The guests lastname is required")] public string LastName { get; set; }
}
public class CustomerViewMetaData
{
[Required(ErrorMessage = "The customers firstname is required")] public string FirstName { get; set; }
[Required(ErrorMessage = "The customers lastname is required")] public string LastName { get; set; }
[Required(ErrorMessage = "The customers emails is required")] public string Email { get; set; }
}
As you can see, it's nothing fancy or strange in there... Can it be fixed? Is it a bug in ASP.NET MVC 2?
Assuming daily certain up to date database is produced via loading from various sources.
Changes need to be applied to historical database based on uid, new records will added , non existing will be softly deleted , some will be updated. Is Ado.Net and Sql statements the most appropriate technology for the task like this ?
Simple question:
What is the pattern for the word character \w in c#, .net?
My first thought was that it matches [A-Za-z0-9_] and the documentation tells me:
Character class Description Pattern Matches
\w Matches any \w "I", "D", "A", "1", "3"
word character. in "ID A1.3"
which is not very helpful.
And \w seems to match äöü, too. What else? Is there a better (exact) definition available?
I need to use the RGBRast software renderer for a DirectX application I'm developing. Currently I'm just including the DLL with my install.
I have read a few places that it is also included with .NET 3.5 SP1. Is this true? If so, where is the DLL located?

Hello
I have a .NET CF project. In the project directory I put a simple xml file (users.xml) which has to be read by the device. When I debug the application on device emulator and try to load the file from code, the Exception is thrown (FileNotFoundException "Could not find file '\users.xml'.").
Is there a mechanism to automatically deploy also configuration files to a device emulator?
I migrated an asp.net app to 4.0. Now I am getting an error "The type or namespace name 'IQueryable' could not be found". The reference to System.Linq is invalid and I can't find it in the reference list. Where did System.Linq go?
What are some common mistakes made by .NET developers, and how can we avoid them?
For example, trying to open a file without checking whether or not it exists, or catching an error unnecessarily.
Please look in to the list before posting new
Please justify your answer as well, if applicable and give examples.

We are developing a very complex eCommerce portal using asp.net c# and the client asked us to make the documentation very similar (look & feel) with ebay api documentation http://developer.ebay.com/DevZone/shopping/docs/CallRef/GetSingleItem.html
Do you have any idea what kind of tool they are using and if not do you know anything that can be configured to produce a similar result ?
Thank you in advance !

Using ASP.Net, I have a server control for which i would like to add the inline css style "background-image:none". However, when i call:
writer.AddStyleAttribute("background-image", "none");
The following inline style is generated (and tries to resolve the url "none"):
background-image:url(none)
Is there a special syntax I can use to set the background image to none inline?
I need to compare tables with the same names in different databases ( Sql Server 2008 ). How using C# code and ADO.Net to identify additions, deletions, updates. Is DataReader going to work in this scenario without stored procedures ? DataReader seems to be suitable for single database connection, or am I missing something ?
Thinks at a backgammon online multiplayer game with over 100, or even 1000 online users. The game communication is done using Ajax + 3 seconds Comet connection interval + ASP.NET technology. Is this a real scenario ?
Didn't so many Comet open connections block the server resulting in big latency ?
We are running an ASP.NET app on a web server with 4GB+ of memory in IIS 6. After reading many articles, it states that we need to set the "maximum memory used" for the Application Pool to 800mb to eliminate the "out of memory exceptions" that are happening for us. However, what should the "maximum virtual memory" in the Application Pool be set to? I can't find information as to what that should be set to.
Is there any .NET implementation of any planarity testing algorithm like Boyer-Myrvold's or anyone else? I looked through the web but I didn't manage to find
