Get Ordinal Method In Class File And Properties In .Net Application?
May 7, 2010
I Have 2 Questions
1) What Is The Meaning of dr.GetOrdianal In ASP.NET Class File? What Is The Purpose Of The Same? Is It Compulsory To Write dr.GetOrdinal While Fetching Any Value From Database?
And
2) What Is The Purpose of Properties (Get & Set ) In Class File? Will It Saves Our Time Of Compilation?

I have a regular method I want to call. I need to use properties of the GridViewRowEventArgs Class within this method.
i.e.
[Code]....
Of course the above code is not valid because I don't think you can put GridViewRowEventArgs within the method like that. I don't want to put it within a event handler because that even handler is doing other things. I want to be able to call this seperatley.

I am relatively new to ASP.NET. I am just wondering if there is way to read values from properties file (similar to rading a properties file from JSP or java).
For example if a property file has something similar to this:
[Code]....
I would like to read all the values for username_list (comma seperated) and also the value of is_valid.

I was just wondering, let's say I created a Method that is in a partial class in App_Code, and this Method would replace the same type of Method that would otherwise be in many files, and so, since it would be called from many files and would probably be called and used very frequently especially because of this. Would this overload this class? I'm not saying what would most likely happen, I'm just asking if it would be even remotely possible?

Using the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService]
public class Controller : System.Web.Services.WebService {
[WebMethod]
public void save_client(aClientArgs client)
{
// Save client data
}
}
Then defining aClientArgs as a sub-class:
public class aArgs
{
public string id = null;
public string name = null;
}
public class aClientArgs : aArgs
{
public string address = null;
public string website = null;
}
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="http://tempuri.org/">
<client>
<address>string</address>
<website>string</website>
</client>
</save_client>
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">
<client>
<id>string</id>
<name>string</name>
<address>string</address>
<website>string</website>
</client>
</save_client>
So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

I have a web application in asp.net and C# that must access a remote server to copy some files. The web application basically deploys other web applications. Let us say that the web app runs on a "developement" server and needs to interact with a "production" server. From the user's point of view they are both remote machines. He accesses the application (running on the "developement" machine) on his browser and does not see the code and the access credentials to the "production" machine

Since App_Code doenst exist as an ASP.NET Folder, I manually added App_Code as a regular folder, then within that I placed technologydescriptor.cs. Although it now has the appearance of an ASP.NET Folder.But for some reason my code doesnt recognize this class if its w/in the App_Code folder. This is picked up if it is not within that folder- why?Error: "The type or namespace name could not be found, are you missing a using directive or assembly reference"

I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):
Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating
Dim entity As New Login()
Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo)
entity = accountControl.Entity
e.InputParameters.Add("entity", entity)
End Sub
And here's the markup for the datasource:
<asp:ObjectDataSource ID="MasterDataSource" runat="server" EnableCaching="true" CacheDuration="10"
SelectMethod="SelectAll" UpdateMethod="Update" TypeName="Data.DAL.LoginDAL">
</asp:ObjectDataSource>
My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:
Public Overloads Function Update(ByVal entity As Login)
If entity Is Nothing Then
Throw New ArgumentNullException("entity")
End If
MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _
entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax)
End Function
When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the
last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?

I was trying to write a method to be called from a CustomValidator to determine whether a string property was unique or not. I was trying to make it generic so that I can reuse the code for many different string properties. I'm using reflection. Does this seem like a way too complicated way of doing this? Does there happen to be a better way of doing this but still making it generic?
public virtual bool IsPropertyUnique(T entity, string newValue, string propertyName)
{
var values =
Context.GetTable<T>.Where(e => string.Equals(e.GetType().GetProperty(propertyName).GetValue(e, null), newValue)).ToList();
return values.Count == 0;
}

I have a method that lists all Properties from an expression.
It goes like this:
[Code]....
After that, I would put it to string (i.e. "Property1.Property2.Property3"). What I want to do is if a Call expression type comes up - only for indexed properties - , it should have some way of adding it so when I put it to string it would output "Property1.Property2[0].Property3".

I'm reading a bit of Pro ASP.NET MVC Framework and following a few tutorials written in the book. In the very first tutorial, creating a MVC site for dinner (PartyInvites), I encoutered this problem. While I try to reference some properties from Model class, the compilation error occured. Eg. the following code failed.
[Code]....
and the error message
Compiler Error Message:
CS1061: 'object' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) I imported the Model folder into the controller too. I dunno what I'm missing here. Sorry, if it sounds a bit umm hard to understand cuz I just started picking up MVC this morning. Looking for any input.

There is a SearchPage which has a properties ErrorMessage, SuccessMessage etc. This is basically a MVP pattern so for each page(view) there is IView that contains definitions for all the properties
I am using decoratoe pattern to set these peoperties dependingon the message type. There is another Interface IBaseMessage which has a method DisplayMessage() and a class BaseMessage which implements the interface. This class has a definition of the view
Interface IbaseMessage
{
DisplayMessage()
}
baseMessage:IbaseMessage
{
public Iview _view{get; set;}
DisplayMessage()
{
_view.Warning ="<message>"
_view.error="<message>"
}
Here, I am not able to set the message to the view properties. I am getting the error as "Object reference not set to an instance of the object"

I am interested to know what happens with unused properties of a class when an object is instantiated?
Are there performance hits for having additional unused properties? What about complex properties that are accessing the database, but I'm not using them, are they still being loaded?
