Hi  All,

I have converted visual studio 2003 project to visual studio 2005 but m getting error as :

"Attribute 'CodeBehindFile' in the @ Page directive is no longer supported. Convert this page to the new code-behind model by opening the Web site (project) containing the page in Visual Web Developer. "

As 2005 does not support CodeBehindFile i changed it to Codefile, still it is giving the same error.. M stuck here please let me know how to resolve this.

Thanks in Advance, 

Chainv

Hi,

What version of Visual Studio 2005 are you using? It seems that it is Beta version which has such issue when we convert ASP.NET 1.x to ASP.NET 2.0.

In the Visual Studio 2005 RTM, this issue should be resolved. For more information, you can refer to http://forums.asp.net/t/931582.aspx

You also can refer to Common Web Project Conversion Issues and Solutions (http://msdn.microsoft.com/en-us/library/aa479312.aspx).

I look forward to hearing from you.

Hi,

Thanks for your response.

For error "Could not load file or assembly...", we can try to re-add reference to this assembly in Visual Studio 2005.

For the second error, there is the same type in two assembles: "System.Web.UI.WebControls.TreeView" and "Microsoft.Web.UI.WebControls.TreeView". ASP.NET 2.0 uses former one, you can remove  "Microsoft.Web.UI.WebControls.TreeView" from your website.

You also can create new ASP.NET 2.0 project, and then add the contents to this new one from the converted one, and then add reference for it.

Thanks.

Hi,

Thanks for response. i have removed Microsoft.Web.UI.WebControls.TreeView from the code .

Now m getting 258 errors:    Error 85 'System.Web.UI.WebControls.TreeNode' does not contain a definition for 'Nodes'

I have used treeview in many pages so it is giving these many errors.

Thanks,

Hi,

It seems that you used MicrosoftWebControls such as TreeView, which is only designed for ASP.NET 1.1.

In ASP.NET 2.0, we can use equivalents Sytem.Web.UI.WebControls in ASP.NET 2.0 to replace them.

For example, we can use MultiView control (http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.multiview(VS.80).aspx) to replace PageView.

Thanks.
