Exchange Provider

The provider model supported by RadScheduler can be used for synchronization with multitude of data sources. The provider uses Exchange Web Services over HTTP/HTTPS as means to communicate with the Exchange server.

Distribution

The Exchange provider is distributed as web site project in our RadScheduler SDK and the source code of the provider is located in the App_Code folder.

Usage

Please be aware that Reminders functionality is not supported when Exchange provider is used.

You are able to instantiate the provider through code. This allows you to provide different server URL and credentials, for example, depending on the current user.

For example:

protected void Page_Init(object sender, EventArgs e)
{
    ExchangeSchedulerProvider provider =
        new ExchangeSchedulerProvider(@"https://yourURL.com/EWS/Exchange.asmx", "username", "password", "domain", "CalendarName");

    // Alternatively, you can pass in existing credentials (NetworkCredential object):
    // new ExchangeSchedulerProvider("https://dc1.litwareinc.com/EWS/Exchange.asmx", credentials);
    RadScheduler1.Provider = provider;
}  

Protected Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs)
    Dim provider As ExchangeSchedulerProvider = New ExchangeSchedulerProvider("https://yourURL.com/EWS/Exchange.asmx", "username", "password", "domain", "CalendarName")
    RadScheduler1.Provider = provider
End Sub

You can configure the provider entirely declaratively. First you need to add the following configuration section to your web.config file:

<configuration>
   <configSections>
       <sectionGroup name="telerik.web.ui">
           <section name="radScheduler"
type="Telerik.Web.UI.RadSchedulerConfigurationSection, Telerik.Web.UI, PublicKeyToken=121fae78165ba3d4"
allowDefinition="MachineToApplication" requirePermission="false"/>
       </sectionGroup>
   </configSections>
</configuration> 

Then add the provider section itself. Be sure to specify the correct server URL, username, password and domain:

<configuration>
   <telerik.web.ui>
       <radScheduler defaultAppointmentProvider="Integrated">
           <appointmentProviders>
               <add  name="ExchangeSchedulerProvider" type="Telerik.Web.Examples.Scheduler.ExchangeSchedulerProvider"
serverUrl="https://dc1.litwareinc.com/EWS/Exchange.asmx"
username="wl" password="pass@word1" domain="litwareinc" />
           </appointmentProviders>
       </radScheduler>
   </telerik.web.ui>
</configuration> 

The provider is now set up and will be shared by all RadScheduler instances that are configured to use it. This is done by setting the ProviderName:

<telerik:RadScheduler RenderMode="Lightweight" runat="server" ID="RadScheduler1"
ProviderName="ExchangeSchedulerProvider">
</telerik:RadScheduler>
