User Instance login flag is not supported

[Will Ferguson]

OPening the datagrid example I get this error:
User Instance login flag is not supported
I know it must have something to do with sql setteings.. any ideas on how to troubleshoot?

Hello Will,

You can modify the connection string to our demo data in app.config file of the examples project:

<connectionStrings>
        <add name="Telerik.Windows.Examples.Properties.Settings.NorthwindConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\DataSources\Northwind.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
    </connectionStrings>

In your case you can delete user instance flag.

Sincerely yours,

Hi Will Ferguson,

You can find the examples project in the installation folder of RadControls for WPF (typically "C:\Program Files\Telerik\RadControls for WPF Q3 2009"). There you will find a folder called Demos which contains the project "Examples_WPF.CS". Once you open the project you just have to modify the app.config file and rebuild.

All the best,

I found the examples project. I open it and get 333 errors.

Hello Will Ferguson,

Have you modified any other parts of the example project besides the app.config file? We will also appreciate it if you could send the the first couple of errors that appear in the Output window of Visual Studio.

Hi Will Ferguson,

Hum, that is very strange - judging from the VS2008 errors of the VS2010 conversion process might have broken some of the code. May I ask you to download our manual installation package and overwrite your current demos with the ones that are contained in the manual installation zip. Once you have original demos could and the app.config modifications are applied could you please try to compile the examples once again? 

Hopefully this time it will work.
