I haven't done much C# programming in a year - now I can't remember how to insert button click event code into the code behind page for an asp.net button in the html side. I know there's a slick way to do it, bit I can't find it anywhere. I remember that it automatically created the event code from the, for example, Button1 element. The event would then be Button1_Click(...).
My site was working fine in Visual Studio 2008, but the code-behind pages have suddenly stopped recognising new controls which I add to the main page. For example I added a label with id 'lblEventHeader' to the main page and then tried to set a text property in the Page_Load event. I get a compile error of "the name 'lblEventHeader' does not exist in tne current context. Existing controls, which I added before this problem seems to be unaffected.
As far as I am aware, I have not done anything which should cause this. I have even reinstalled Visual Studio, but I still get the same error message. Have I inadvertently deleted or corrupted a reference file. I have checked the Codefile and Inherits properties of the page.
can Visual Studio 2008 be All-In-One tool to integrate source code continuously from team members, build, unit test?
Having used Visual Studio Team Edition 2005, unit testing each method within VS itself. I strongly believe that it is feasible to add-on tools. Example ankhsvn tool to use SVN from Visual studio [URL]
In my investigating i have come across number of tools(shown below) to use with Visual Studio 2008 professional
Development tool:- Visual Studio 2008 professional using Subversion as source control tool. Continuous Integration:- Hudson or Cruise control Build tool:- NAnt Testing:- NUnit, Selinium As Visual Studio 2008 can be used for unit testing I think NUnit is out of consideration.
In the same way i would like to have any other tools/add-ons to Visual studio to implement continuous integration, building and unit testing. This process should be automated such a way source code between team members is continuously integrated, built and unit testing is done as configured.
Objective is to use few number of tools as add-on to Visual Studio or achieve most from Visual studio itself (example unit testing). Visual Studio should be all in one tool.
I am aware that Team Foundation Server best suits my requirement, but it is out of scope due to its cost.
I've got an ASP.NET 4 web forms application I'm building in Studio 2010. The solution has two projects. A web forms application and a class library. I have added a reference to the class libraryr project in the web forms project, but when I go a code behind page in the web forms project, it does not recognize the class from the class library and throws the "type or namespace <class> could not be found ...." error. Adding a using <class library projec> does not work either as it does not recognize that.
What am I missing?
I started a new web project in VS2008 coding in vb.net. When I double-click on a control in the designer screen to go to the vb code page so I can code on some events, the control does not show in the control dropdown which means I cannot get to all of the different events. The only way I can do this is to add a line like below inside the class at the top:
[Code]....
I am working with another project that does not have this problem. Is there a setting that changes this?
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)?

View 2 RepliesI'm missing a the code browser when I create pages that have the code not placed in a seperate file. For pages with .asp.vb files I get the browser correctly.
I think it's called a code browser but just in case it's not I mean the dropdown that shows Page Events, Buttons and other controls that can be selected along with their events.
How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?

View 2 RepliesWhen I try to set breakpoints in a JavaScript code file, I get the warning, "The breakpoint will not currently be hit. No symbols have been loaded for this document."
This is a fairly large project that was working normally under VS 2008. I just installed VS 2010 Pro Academic, and this is one of the new problems that have appeared. It's running under Win 7 64-bit, IE 8, and both of the IE "disable script debugging" options are turned off. Debugging is enabled in the web.config file. The JavaScript code in question is being executed normally, and inserting "debugger" in the code works as expected. While running under debugging, you can open the corresponding script document from the Solution Explorer, Script Documents, and insert breakpoints just fine. Attaching to the IE process (from the Debug menu) doesn't seem to make any difference.
Basically, everything I can think of looks normal, and yet I can't insert breakpoints into the original source code with VS 2010. The problem is reproducible on more than one JavaScript source file. I rebooted and consults The Great Google, all to no avail.
This is a real headache for development. Has anyone else discovered a fix for this?
(UPDATE: I spent a few hours and created a new project, and copied all of the files from the original to the new one. Now, I can set breakpoints n the new project, but still can't in the original. Something's different between the two, but it isn't clear what it could be.)
I am having an issue with my Windows forms application. I am trying to insert a record into a table. It says the rows affected is 1 however the row is not in the database. Here is my code:
<code>
System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand("AddSong",new System.Data.SqlClient.SqlConnection(Properties.Settings.Default.Database1ConnectionString));
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@length", dict["Total Time"]);
cmd.Parameters.AddWithValue("@genre", dict["Genre"]);
cmd.Parameters.AddWithValue("@name", dict["Name"]);
cmd.Connection.Open();
cmd.ExecuteNonQuery();
cmd.Connection.Close();
cmd.Dispose();

View 1 RepliesI am using C#, Object Data Source, formview and a BLL. I have two drop down lists and two data sources. One populates the other. Drop down list #1 populates Drop Down list # 2 based on its selection . Drop down list # 1 is populated with DataSource #1. Forview is using DataSource #3 to send the ietms. When I add: SelectedValue='<%#Bind("Make_ID") %>', I get the error below:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control
I have seen a solution online but it is using LINQ and I am not familiar with it. I need to find the selected value of the drop down lists.

View 5 RepliesI work with Visual studio 2005 and Sql server data base. I extract 1 million rows from a database and I put the rows in a Sql table. With a simple direct extraction, in a few minutes I complete the operation:
Dim cmd As New SqlCommand(query, cnSql)
cmd.ExecuteNonQuery()
cmd.Dispose().
But, if I must select and modify some fields between extraction and introduction, it takes a lot of time!
I work in this way. I extract rows from Dbase, Table1, and I put all into a Collection using dataReader:
Dim cmd As New SqlCommand(query, cnSql)
Dim coll As New Collection
coll.Clear()
Dim dr As SqlDataReader = cmd.ExecuteReader()
I replace some fields with the string "YES".
Dim toRepl As String = ""
If dr.HasRows Then
Do While dr.Read
toRepl = dr(5).ToString
If Len(toRepl) <= 3 Then ToRepl = "YES"
collPrel.Add(dr(0).ToString)
collPrel.Add(dr(1).ToString)
.................. ..............
collPrel.Add(toRepl)
collCount = collCount + 1
Loop
End If
dr.Close()
cmd.Dispose()
Now, I insert all into a SQL Table2:
Dim a As String = "", b As String = "", c As String = "" etc.
For i = 1 To collPrel.Count Step 6
a = collPrel.Item(i).ToString
b = collPrel.Item(i + 1).ToString
.............. ...............
f = collPrel.Item(i + 5).ToString
queryIns = "INSERT INTO Tab (name, adress, etc)
VALUES ('" & a & "', '" & b & "', '" & c & "', etc. )
Dim cmdIns As New SqlCommand(queryIns, cnSql)
cmdIns.CommandTimeout = 600
cmdIns.ExecuteNonQuery()
cmdIns.Dispose()
Next
This way to work goes right but it is necessary a lot of time for completing the operation.
There is no way I'm the only one who thinks that I'm missing such a shortcut in Visual Studio.In the markup (aspx) I begin writing the event name "On..." then choose the event I need. What I'm looking for now is functionality for auto-inserting the event name and the delegate method in the codebehined exactly as it's done from the Design view.It's a simple and very helpful functionality that's obviously missing - or I havn't been able to localize it yet.Does any one know if it can be done in VS? Maybe using ReSharper?
View 2 Repliesi am new to ASP.NET development, and i am a little bit curious on the asp.net code behind mechanism.
i know why we use it but what i would like to know is:
the relation between aspx page and the code behind who does the linking between these two separate files ?
how does it work?
how an element created in aspx page can be accessed directly from code behind ?
I am really worried about this. I recently got hold on VS 2010. I had been working on a control when my VS 2010 crashed upon me. I terminated all of the applications that might be slowing down VS. To my horror when I restarted VS I had lost all of the coding and classes written within that control's code behind file which was SearchFilter.ascx.cs. IT shows the size of this file as 0KB. There nothing in it now. Does any one out there know how can I recover my file, it had almost over 700 lines of code. I would be really very grateful to you people out there.
