#InvalidateSchemaOnNew

[[_TOC_]]

##About

Gets or sets the value indicating whether database schema is invalidated when user creates new report.  If [[CacheSchema|http://wiki.izenda.com/create/API/CodeSamples/CacheSchema]] is set to true, InvalidateSchemaOnNew ensures that the user will see the latest schema information (useful if custom columns and tables are in use) and that new reports (especially if you are using DatabaseAdHocConfig and/or any ReportSet overrides) will appear in the Report List immediately.  The DatabaseSchema object is cleared from cache as soon as the **New** button is selected.

**Default Value:** False

##Global.asax (C♯)

```csharp
//main class: inherits DatabaseAdHocConfig or FileSystemAdHocConfig
public class CustomAdHocConfig : Izenda.AdHoc.DatabaseAdHocConfig
{
  // Configure settings
  // Add custom settings after setting the license key and connection string by overriding the ConfigureSettings() method
  public static void InitializeReporting() {
    //Check to see if we've already initialized.
    if (HttpContext.Current.Session == null || HttpContext.Current.Session["ReportingInitialized"] != null)
      return;
    AdHocSettings.LicenseKey = "INSERT_LICENSE_KEY_HERE";
    AdHocSettings.SqlServerConnectionString = "INSERT_CONNECTION_STRING_HERE";
    Izenda.AdHoc.AdHocSettings.AdHocConfig = new CustomAdHocConfig();
    AdHocSettings.InvalidateSchemaOnNew = true; //The relevant setting
    HttpContext.Current.Session["ReportingInitialized"] = true;
  }
}
```

##Global.asax (VB.NET)

```visualbasic
'main class: inherits DatabaseAdHocConfig or FileSystemAdHocConfig
Public Class CustomAdHocConfig
    Inherits Izenda.AdHoc.DatabaseAdHocConfig

Shared Sub InitializeReporting()
        'Check to see if we've already initialized
        If HttpContext.Current.Session Is Nothing OrElse HttpContext.Current.Session("ReportingInitialized") IsNot Nothing Then
            Return
        'Initialize System
        AdHocSettings.LicenseKey = "INSERT_LICENSE_KEY_HERE"
        AdHocSettings.SqlServerConnectionString = "INSERT_CONNECTION_STRING_HERE"
        Izenda.AdHoc.AdHocSettings.AdHocConfig = New CustomAdHocConfig()
        AdHocSettings.InvalidateSchemaOnNew = True 'The relevant setting
        HttpContext.Current.Session("ReportingInitialized") = True
    End Sub
End Class
