I am running through this tutorial on ASP.NET MVC: [URL] Everything seemed to be going fine. I created my DB, created my Model classes, created a controller class and then started creating some Action handlers. When I finally created the page that submits updates to the DB, I got the following error:
System.NotImplementedException: The method or operation is not implemented.
Line 49: public void Save()Line 50: {Line 51: db.SubmitChanges();Line 52: }
when I call the "SubmitChanges()" method of the DataContext class. I tried recreating my DBML file from my tables, but I still get the same error.
I have a class library project which consumes multiple webservices. I have created a test project in VSTS and try to call one of those service
But I'm receiving System.ServiceModel.EndpointNotFoundException. In my Test Project I have added one app.config file and added endpoint as available in my Serviceclass library project app.config.
I have web projects build in VS2003/1.1 framework and deployed in a webserver with IIS setting specified to 1.1 framework.lets say project X
I also have another web project which is build with VS2008/2.0. IIS setting - ASP version 2.0 is selected and all pages are assigned to run with 2.0* dlls. Lets say project Y
Now the problem seem to be when I hit project x, sometimes it throws errors like "error BC30456: 'Initialize Culture' is not a member of 'ASP.**"
During troubleshooting this issue, I browsed through 2.0 Temporary ASP.Net files "C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files" and found temp files generated for project X. (HUH?)
How/why 1.1 project gets compiled in 2.0 only when it errors out.( or we could put it this way that it errors out every time it gets compiled in 2.0 which it is not supposed to)
I'm confused as to why this is happening when project X has nothing to do with .net 2.0.
Adding this info:
IIS version 6.0
I forgot to mention that project X works 95 percent of the time without any errors under 1.1. This error throws randomly which we could not recreate. The time the project error out is at the same time it gets compiled with 2.0
This works fine locally. A 404 throws a 404. On the shared hosting it throws up the standard server 404 page unless I specifically set 404 to point to /Error/NotFound. That's fine. Now it will show the custom 404 page except the response status code is 200. So if I try to throw Response.StatusCode = 404; in my NotFound action in ErrorController like this:
Csharp Code:
[code]....
the server throws a status code 500 Internal Server Error but my GeneralError page doesn't show, just a blank white page with no source.
I've tried many different combinations but I can't seem to find how to make it show my custom 404 page along with a 404 response.
and when the value in the Database in null (""), it throws this error: ArgumentOutOfRangeException: 'pn' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I am using a Datapager in my project with a ListView control. The Datapager is set to use a querystring value Page, so that a typical URL looks like: [URL]. The problem is that the ListView throws an ugly error if the pageview is invalid (0, for example).
The error is: Specified argument was out of the range of valid values. Parameter name: startRowIndex
The error originates in the ListView SetPageProperties method. What is the best way to address this? Can I override the SetPageProperties method in some way, to check the startRowIndex parameter? Here's a very simple page that replicates the error: [URL]. A copy of a simple webapplication project demonstrating the error: [URL]
I added a service reference via the add service reference method. I can see all of its services in the intellisense but when I run the project and it executes the line where I instantiate the service : MyProjectName.ServiceReferenceName.IServiceReferenceClient client = new MyProjectName.ServiceReferenceName.ServiceReferenceClient;it throws this error:Could not find default endpoint element that references contract 'ServiceReferenceName.IServiceReferenceClient' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.
I have a conditional statement running on my aspx page which looks for a value from a static property (i.e. the object should not need to be declared).
[Code]....
This is the error that is thrown: "BC30451: 'CurrentSession' is not declared. It may be inaccessible due to its protection level."The class is public and to make matters more confusing, it works fine in certain environments but blows up on some.
I am using AS 400 OLEDB with .NET. It uses '?' instead of '@param to bind parameters with a commandNow there is a situation where the command is like
SELECT ... FROM (SELECT ... ROW_NUMBER() OVER(ORDER BY ColumnName) as RowNum FROM Employees e ) as DerivedTableName WHERE RowNum BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1 Now my command becomes SELECT ... FROM [code]...
I've got a Dropdownlist with CategoriesI've also got a Listbox with Items filled using the selection from the DDL (autopostback=true).I have a SQLDataSource for each one.the DDL populates perfectly. the listbox SQL DataSource uses a stored procedure, that, on its own works perfectlyIt works well just as outlined above. However, when I add the following properties to the DDL, I get an error: appendDataBoundItems=true and '--Select--' (tried 'Select' also) as an item the error is:Input string was not in a correct formatI also set up the sqlDataSource selecting event handler, so that it would check for 'Select' first, but it bypasses that handler when debugging, and goes straight to the error msg

I'm trying to use a Tab control with 5 tabs inside a form view, when I view my aspx page in Visual Studio 2008 it displays a error message stating "There was an error rendering the control. Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "AjaxControlToolkit.properties.Resources.resources" was coreectly embedded or linked into assembly ... " running the site just shows a blank page (as the control isn't rendered).
If I remove the tab control from within the ItemTemplate (or EditItemTemplate) and put it directly onto the page it works fine. Googling for the error suggests the references aren't correct, so I've reset the toolbox, and re-added the reference - this time referencing the file in my Bin folder (not the installation path of the Ajax Toolkit). Still it throws the same error. Finally I've stripped the code out into a page with the bare minimum (no code behind) and it still throws the same error. I'm sure I had this working previously. I'm using Visual Studio 2008 on Windows 7 and I'm using the 3.5 files from Codeplex (AjaxControlToolkit.Binary.NET35.zip) targetting .NET Framework 3.5.
I have designed a gridview one of the fields of which I want to send the user to an URL onclick. After browsing the net for a while, I opted for converting the BoundField to a TemplateField. The same OLAP metric ([Measures].[GP]) works fine in the bound field yet produces an error in the Template:
I recently installed VWDE 2010 and SQLE 2008 R2 and have built a basic site, but when I try to launch the Web Site Administration Tool, it fails to come up in a browser window. The server starts and I can right click on that and choose "Open in Web Browser", but when I do that an error message immediately shows up saying, an error was encountered. Please return to the previous page and try again with no other information given. When I click on "How do I Use this Tool?" in the top-right corner of the window, it immediately says the following:
Tool Has Timed Out
As a security measure, the Web Site Administration Tool times out after a period of inactivity. Changes to machine.config or web.config may also result in the tool needing to be restarted. To continue configuring your web site, restart the tool. The same message immediately comes up no matter what tab I click on. I have searched the internet and have made sure that the path doesn't have any spaces or non-alphabetic characters, run aspnet_regsql, restarted the IDE as well as the computer, but nothing works.
I'm developing an ASP.NET app with a MySQL backend, using the MySQL Connector Net 6.2.3. I have a DetailsView with an insert command that is throwing the error:MySql.Data.MySqlClient.MySqlException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?,?,?,?,?,?,?,?)' at line 1My code is:
[Code]....
If I hardcode values into the insert statement, it works fine. But when I put the ? placeholder in, it throws the error. Can anyone help me pinpoint the problem or offer a workaround solution?
I have a page which submits a form in my local system but in my production system when i click my submit button it just freezes with the error in my web developer toolbar saying Error: Sys.WebForms.PageRequestManagerServerErrorException: When calling stored procedures and 'Use Procedure Bodies' is false, all parameters must have their type explicitly set.
I have an ASCX control which is a special dropdownlist. I add that control dynamically to the page and fill it with data. This control has a postback that will change the contents of a second dynamically created standard dropdownlist.
When I change the selection on the first dropdown, the indexchanged fires and I get new data and attempt to place it in the second dropdownlist's items collection, by first clearing it then filling it with new data.
This works fine the first time a change the selection, but when I select a second time the following error is thrown:
The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.
I'm not adding or removing new controls in the fired event, only changing data. And again, it works the first time, but doesn't subsequent times.
If I disable stateview on the child control, then the control just doesn't get updated with data at all.
i have installed ajaxtoolkit 3.5 but when i debug i am getting this error Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' even i have changed my tags to
We are working on a web application and the target deployment includes Windows 2003 64-bit. When we run the application on the 64-bit OS, it gives the following error:
The entry 'asp:System.Web.UI:System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' has already been added
And if we remove the line <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>, it seems to work.
Can somebody understand the problem and take corrective action? The application does not compile on 32-bit OS without this.
I don't know what I'm making wrong.I have a submit button, and on click it should execute the funktion in the code behind, but I get the error that the funktion is undefined.this is my code in the .aspx webform:
The following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid() Dim id As Integer = Integer.Parse(Context.Request.QueryString("id")) Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString Using con As New SqlConnection(strConnString) Using cmd As New SqlCommand() cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.
