So I am a beginner with .NET, Visual Studio, C#, etc. But I am wondering something about the code behind a form and a difference I am seeing in 2008 versus 2005. So lets say I have a simple Windows Form app, C#, and I throw a couple controls on it. Then I add some MessageBox.Show event handlers for the default events....in 2005 there is that little section within the code that is hidden that basically contains the code that 'registers' the controls with the system....I think. That may be a bad definition?? Basically I think that automatic code generated here just basically associates the event to the event handling code....anyway.
I can see this is 2005 (once I click the like gray box), but it does not appear anywhere in 2008. So this has to exist somewhere, and I just wanted to ask to be familiar with what is going on since I am new to this. I still have to figure out how to turn on the code line numbering in 2008, but I can google it.
I have a VS 2008 solution. I need to copy an existing .aspx page and re-name it to something else (need to make modifications to that newly copied page). But I keep getting compilation errors saying that duplicate text boxes exist. Can't I have control on different .aspx pages with the same name? How can I do this elegantly?
Is it possible to do things in a PHPish way in ASP.Net? I've seen <%= %> but I've tried it and couldn't get it to work. The PHPish equivalent of what I want to do is
When writing inline code in an .aspx file and some lines down closing a statement with <% } %>, Visual Studio tries to be nice but messes it up by rewriting it all. Is there any way of turning this rewriting off, but only for inline code?
I have a page with a Textbox, a Button and a Label control. On Button_Click event , I store the value of Textbox in a variable called S using code behind.
I want to show the value of S in the Lable control using inline code but not using the code behind. ?
I have developed a User Control in inline code model and convert this into dll and try to add it into Visual Studio ToolBox. It shows error "There is no component found in the object.". It is showing actually because i have not added ToolBoxData attribute just before the class declaration, because there is no class declaration in the inline code model. I don't know where i have to add ToolBoxData attribute.
etc., which is placed inside of an ItemTemplate inside of a TemplateColumn. In the CodeBehind page I will bind a value to the OrderXml field, which occasionally is NULL.
I have an application that uploads an Excel .xls file to the file system, opens the file with an oledbconnection object using the .open() method on the object instance. The upload and writing of the file to the file system works fine but I get an error when trying to open the file on our production server only. The application works fine on two other servers (development and testing servers).
The exception comes on production server at connection.Open() some times, when I reset the asp.net worker process it started to work but after some hours/days It occurs again. how can I fix this issue which comes in production some times but very irritating, or there is some other work around.
I work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.
I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ?
Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.
I'm using vs2010, asp.net 4 webform.Is there anyway which i can update a code behind file (ascx.cs) file without compile the whole site.because i just want to debug some ascx.cs file, and compile a big whole site will cost 1 minutes at least.
I lifted some nice code to handle memberships, but I want to add a customer specific field. My issue is how to reference my class from the inline c# code.

The problem is the line csUserProperties.AddNew(intUserId, lngCustomerId); -- I get the error "The name 'csUserProperties' does not exist in the current context. I have <%@ Import Namespace="csUserProperties" %> at the top of the file. I also tried everything with no namespace in the class below.
After insert a grid or any other tool into an aspx page it generates enough code for that tool(for ex.): <dx:ASPxGridView ID=ASPxGridView1 runat="server"></dx:ASPxGridView>...
But,after adding any property to this control (like Show group Panel) it generates more than 3000 lines of code in aspx page () and after adding any other tool the code is increasing in a enormous way...
How can I reduce the code, maybe there is a property(settings) in DevExpress option...
I want to create a Dynamic aspx Page in current solution through code-behind..forexample i have a 2 text-boxes one for page-Title another another for page-Content and a button.. whenever that button is pressed, An aspx Page should be created in current solution and should be included in the current solution
I have an asp.net application. I want to add a global.asax and global.asax.cs file to my project. In the IDE when I select to create a new global.asax file, the option to create a CS code behind file is greyed out. When the global.asax file is created, no code behind is created, instead code is placed in the global.asax file and the global.asax.cs file is never created? Why is the option for a C# code behind file greyed out?
I keep recieving this error when trying to add the toolkit to my application: "There was an error loading types from assembly v:my intranet etProjectinAjaxControlToolkit.dll Request for the permission of type System.Web.AspNetHostingPermission, System, Version=2.0.0.0,culture=neutral,PublicKeyToken=b77a5c561934e089 failed"
This has only recently started happening.. There are already AJAX controls on the page which still work but I want to add new ones with the new toolkit but for some reason cannot add the toolkit anymore. If I copy the toolkit to the local C: drive of my PC and add them I can , but when I then copy my page back to the server, none of the controls are working.
I use the sqldatasource control a lot with stored procedures. But this time I'm using some code I found online where I am defining the new sqldatasource in the code and using it. You can see this below. I am getting a NullReferenceException on the first SelectParameters line and not sure why. Do I need to add the parameters different?
Code: Dim SqlDataSource As New System.Web.UI.WebControls.SqlDataSource() SqlDataSource.ConnectionString = ConnectionString SqlDataSource.SelectCommand = "MySprocName" SqlDataSource.SelectCommandType = SqlDataSourceCommandType.StoredProcedure SqlDataSource.SelectParameters("Distance").DefaultValue = 25 SqlDataSource.SelectParameters("ZipCode").DefaultValue = "31410" Dim arg As New DataSourceSelectArguments() Dim dv As System.Data.DataView = DirectCast(SqlDataSource.[Select](arg), System.Data.DataView)
we try to disable a server control at code behand, say:

I have a custom gridview control which is a class library project.I want to be able to specify the css class for the gridview which I can do.But I also want to set a default css stylesheet to the gridview. So if I don't override it using the cssclass property it must get it's cssclass from the default stylesheet I have in my project.
How can I specify the default stylesheet. I have a stylesheet in a folder called "Styles" in my project.
I am working solo on an Asp.net/C# project created by someone in the past. I created two new web forms, and then built the prjocect and did the deploy using a TFS team build project. For some strange reason, my Aspx file is not getting copied to the destination DEV server. It does get copied to a temp folder on that server, but in the end, the team build is failing and not copying over the new Aspx file.
So until I figure out how to fix the team build script, is their a way to just copy the Aspx file out to the desired server location? That as well as copying out a dll which is associated with the build file?
This is the current architechture and this is the question I have: Current architechture: We have an intranet application. No one accesses from outside the firewall. It's pretty simple architechture. We have a webservice and WebUI. The Web UI calls the webmethods of the webservice. So far so good. It works fine. Both webservice and WebUI runs under the context of the same service account (non human user account) that we created. The security is a role based security. If a user is a specific AD group, he can access with web UI. On the webui and webservice we have "Integrated windows authentication".
So all the users and the service account that runs this webservice are in this AD group Apr-DataWriters. When a user launches this webUI, I want to find out either his box number of IP address of this box and datetime stamp. How can i get that information.
Is there any tool for Visual Studio 2008 which can reformat ASPX code to make it more presentable (eg insert line breaks, format the lines so they wrap when necessary, etc)?
