I have a project with lots of ObjectDataSource controls. They collect their data from various classes. am going to move all my classes (that handles the DAL) to a separate class library.Will that cause me any problems?How do i set the TypeName (directly in the .aspx file)?
View 2 RepliesI'm trying to use a MasterType TypeName to access a class with master pages. This works when I'm using .NET 2.0, VS 2005, and C#. When I try this using .NET 3.5, VS 2008 and C# I get the error:
The type or namespace name 'classA' could not be found (are you missing a using directive or an assembly reference?) and it is pointing to the Default.aspx.designer.cs
In the default.aspx I have:
<%@ Page Language="C#" MasterPageFile="...
<%@ MasterType TypeName="classA" %>
I have added a folder App_Code to my project and in that folder I have a class file "classA.cs" that contains:
Using ...
Namespace Project.App_Code
{
public class classA : System.Web.UI.MasterPage
...
The main difference that I see from where it works and where it doesn't work is that where it doesn't work it uses the namespace called Project.So I figure my problem is in the including the class classA in the namespace or properly including the namespace and / or App_Code directory in the MasterType TypeName which I don't seem to be able to figure out.
I am using Visual Studio 2010 for the first time. I program in MS Access for a long time at decide to move to the ASP world. My problem is that I design my first web .aspx default page with a simple data grid. I decided to connect the data via the business object data adapter. I use the Dataset designer to great the dataset. All looks well and works fine on my PC. But when moved to the server I get the Terror "The type specified in the TypeName property of ObjectDataSource not found".
From my reading for the past two days, it seems that something need to be define (a class of some sort) to let ASP know where to find the data adapter. If this is the case, then why did not Visual Studio 2010 did not automatically build the class in the appropriate BIN/ APP_CODE or Global directory and more importantly, why would it work fine on the PC , but not on the server. I am totally blind-sided by Visual Studio 2010 allowing me to design and test on PC but throws me a curl ball with moving to a server. Am I assuming to much from Visual Studio 2010???
What is the solution.. What I am looking for is to know where exactly where and how to write this class. I am so new to ASP, all of my reading just confusing me more and more by reading so many post on this error. I know it is probably a simple class to write somewhere, but why did not Visual Studio 2010 write it accordingly.
I have a dropdownlist that I'm binding to an objectdatasource within a edit template of a gridview. Everything works fine on our staging server, but when I view on our production server I get the following error:
"The type specified in the TypeName property of the ObjectDataSource 'ObjectDataSource2' could not be found."
The typename is correct. It works on our staging server. What would cause this to not work on our production server? Any way to re-write the code to get this to work? See the code below.

I'm wonder how i can get the userid just after i validate. Is there another method i can use to login than
FormsAuthentication.RedirectFromLoginPage(userName, true);
Here's what i have.
if (Membership.ValidateUser(userName, password))
{
// i get a null object on the below as i haven't logged in yet
Guid UserID = new Guid(Membership.GetUser(User.Identity.Name).ProviderUserKey.ToString());
// some other logic that requires UserId

trying to export a dataset to excel directly. I'm repeating, it's a dataset to excel (NOT DATA GRID OR GRID VIEW TO EXCEL). The problem I face is formatting. I'm exporting the excel which has aroung 13 columns.
A column should be in dd/MM/yyyy 00:00:00 format. Time will always be 00:00:00. It is exporting in correct format only, but for example when the date is Jan 05, 2010, when it comes from database it shows correct format as05/01/2010 00:00:00. When it binds, it binds as 5/1/2010 00:00 which is not suppose to happen.

I have an aspx application using Entity Framework 4.0 and SQL Server 2008. Everything works fine. It's an internal application, so we developed a basic backend for routine maintenance. Some minor data updates are done directly into the SQL Server using SQL Management Studio... the problem is those changes are not reflected in the application! Only after reseting the web service or the server, the new data is displayed.
View 3 RepliesHow can i directly access a .cshtml file in ASP.NET MVC using razor view engine?
For example i have this url: localhost/Home/About. This will load the about site inside the "master" page.
I want to load the about page without also loading the master page. So i was thinking that i could use this url: localhost/Home/About.cshtml. But it's not working.
How can i load a view page without loading the master page?
can i do something like this?
<asp:Button ID ="MyButton" runat = "server" OnClick="javascript:GetVal()" />
I have created several applications now allowing the user to export to excel, word, pdf, etc. But this one is a little different, the client wants to have functionality that would directly export to excel as an attachment in an email. Basically my question is, can I create the excel file without storing it to server prior to attaching and sending out the email? Or do I have to save a copy on the server before I can attach it?
View 2 RepliesWhen I do server side soap service programming, I create proxy classes first using some xsd schemas.
Xsd schemas are already defined by another company.my problem is these schemas have master xsds and child xsds which means on master xsds there are references to child xsds.
In this case I have 2 different questions.
1) Is it possible to use xsd schemas directly to build soap service without generating proxy classes.
2) If it is not possible, I am using vs command prompt by typing xsd /c /l:vb nameofmasterfile.xsd
but while there references to child xsds, I am getting an error msg. thats why I had to flatten these xsds in the past. Is it possible to generate all classes in one shot. any external program also ok.
I wanna connect to aspnetdb but it makes an error says "Login failed for user" this is the connection string in web config :
<add name="UserProfiles" connectionString="Data Source=KIA;Initial Catalog=aspnetdb;Integrated Security=True;"
providerName="System.Data.SqlClient" />
and this is my code:
SqlConnection connection = new SqlConnection();
SqlCommand ComNewCheckSum = new SqlCommand();
connection.ConnectionString = ConfigurationManager.ConnectionStrings["UserProfiles"].ConnectionString;
connection.Open();
ComNewCheckSum.Connection = connection;
ComNewCheckSum.CommandText = String.Format("select UserID from aspnet_Users where UserName = {0}", _UserName);
return Convert.ToInt32(ComNewCheckSum.ExecuteScalar());
how can i pass through error?
I have to create a web app (in C#) that's gonna let my users upload their files straight to Amazon S3 (not enough bandwidth on our own server). It looks like the only way i can do that is posting a simple HTML form to Amazon. The problem is that i have to do some work on my server too, like renaming the files, setting up flags on db when file is uploaded, and so on. I really can't see how to do that without uploading files first on our server, which is out of question, so other solution for this? Amazon S3 forum is pretty poor on this topic.
View 2 RepliesI'd like to write and read TCP Streams directly without any modifications by ASP or IIS. Is this possible?
Edit: Goal is to provide communication between a program and a server. Data exchange between them is less then 25 bytes per connection (in default case). So Headers will cause more traffic then the real data. I need to use ASP.Net because the owner of the server will not let me execute my programs.
i was wondoring which thing is better from below two... first one- retrive data by creating webservice second one- create database connection from code behind call storeprocedure and retive data
View 6 RepliesLike many people using ASP.NET MVC, I've implemented my own custom 404 error handling scheme using an approach similar to the one described here: [URL]
(I actually discovered that post after implementing my own solution, but what I came up with is virtually identical.)
However, I ran into one issue I'm not sure how to properly handle. Here's what my 404 action in my ErrorController class looks like:
[Code]....
The part that's different from the answer in the other StackOverflow question I referenced above is how the 'retry loop' is prevented. In other other answer, the code that prevents the retry loop simply sets properties on a ViewModel, which doesn't seem to actually prevent the loop. Since the action is sending back a response code of 404, then accessing the action directly (by typing "/Error/NotFound" in the browser) causes an infinite loop.
So here's my question: Did I miss another, more obvious way to handle the retry loop issue, or is my approach a decent way to do this?
