grid.aspx.cs:

protected void Page_Load(object sender, EventArgs e)

{

dgAppuser.NeedDataSource += new Telerik.Web.UI.GridNeedDataSourceEventHandler(dgAppuser_NeedDataSource);

}
void dgAppuser_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

dgAppuser.DataSource = AppUser.GetAll();

}

IndexOutOfRangeException: Column LastName was not found.

If the GetAll() method returns IList<AppUser> instead of IList<IAppUser> the sorting is works.

ScriptLoadFailedException.  The script /Telerik.Web.Ui.WebResource.axd..........

Missing call to Sys.Application.notifyScriptLoaded.

The error is only happening for specific users on our network in IE6.  On one machine the app works fine logged in as me but when logged in as someone with less permissions on the same machine we recieve the above message.

From my understanding it comes from either invalid JS or missing the below.

if( Sys && Sys.Application ){

Sys.Application.notifyScriptLoaded();

}

But..........

Why would this message be privelage specific??????  If it works for one user it should work for them both.

Has anybody experienced this before.

Thanks for any help.
