System.InvalidOperationException in LoadXml

[Kevin Cauchi]

Hi there, 

I have a problem on one of my machines when loading the xml in the treeview. 

This error is being thrown:

System.InvalidOperationException: Unable to generate a temporary class (result=1).
;error CS2001: Source file 'C:\Windows\TEMP\duyigyoo.0.cs' could not be found
;error CS2008: No inputs specified

Any ideas?

Thanks

Hi Kevin,

Could you, please, post a sample that will reproduce this?

XmlDocument doc = new XmlDocument();

doc.Load(Server.MapPath("config.xml"));

 

using (StringWriter sw = new StringWriter())

{

                using (XmlTextWriter tx = new XmlTextWriter(sw))

                {

                    doc.WriteTo(tx);

                    RadTreeView1.LoadXml(sw.ToString());

                }

}

Hi there,
This is more information about the problem that Kevin have posted.

Here are my system settings of the problematic machine: 

Windows server 2008 Enterprise 64Bit

Application pool on IIs 7: ASP.Net 4 Classic

Identity: Network Service

It looks like the treeview is trying to save inside c:\Windows\temp
why it is trying to save in temp? on other machines the code is working? Can I set the temp folder location manually?

Hello Clifton,

In RadTreeView we use the default .NET mechanism for XML Serialization. If a file is indeed created, I am affraid we don't posses control on that.

Please, check this article for further information and methods of resolution: http://support.microsoft.com/kb/908158

It seems that the account running the application doesn't have permissions on the %windir%/Temp directory.
