Hello jagadish kumar,

Sorry for the delayed reply, we were quite busy with the Q2 release the last days. What you are trying to achieve could be possible but before giving you any directions we would like to know the version of Sitefinity that you are using - is it the new 4.0 or an older one? This is important because the steps you would have to perform would be different.

Sincerely yours,

Do you want to have your say when we set our development plans? Do you want to know when a feature you care about is added or when a bug fixed? Explore the Telerik Public Issue Tracking system and vote to affect the priority of the items

Hi ,

Sitefinity 4.0 CTP is still under development and its API changes dynamically. You can use Open Access with Sitefintiy and RadControls in the same way as for each other web application. Sitefinity is just consumer for Open Access and its functionality. Sitefinity has its own data providers and persistence classes which use Open Access to commit changes. You can extend the custom providers ( once we finish the development ) by inheriting from the data classes. For instance for Events you should inherit from Telerik.Sitefinity.Modules.Events.Data.OpenAccessEventProvider where you can override some of the base methods or add a new one using OpenAcess. Another option is creating a custom provide from scratch. Generally the provider should inherit ContentDataProviderBase and implement IOpenAccessDataProvider interface.

Below are two samples - delete and create items

public override SomeItem CreateItem(Guid id)

{

var item = new SomeItem(ApplicationName, id);

item.Owner = SecurityManager.GetCurrentUserId();

((IDataItem)item).Provider = this;

t

var securityRoot = this.GetSecurityRoot();

if (securityRoot != null)

{

this.providerDecorator.CreatePermissionInheritanceAssociation(securityRoot, item);

}

else

{

var msg = Res.Get<SecurityResources>().NoSecurityRoot;

msg = string.Format(msg, typeof(SomeItem).AssemblyQualifiedName);

throw new InvalidOperationException(msg);

}

if (id != Guid.Empty)

{

this.GetScope().Add(item);

}

return item;

}

public override void Delete(SomeItem itemToDelete)

{

var scope = this.GetScope();

var securityRoot = this.GetSecurityRoot();

if (securityRoot != null)

{

List<PermissionsInheritanceMap> parentInheritors = securityRoot.PermissionChildren.Where(c => c.ChildObjectId == itemToDelete.Id).ToList();

for (int inheritor = 0; inheritor < parentInheritors.Count(); inheritor++)

{

securityRoot.PermissionChildren.Remove(parentInheritors[inheritor]);

}

this.providerDecorator.DeletePermissions(itemToDelete);

if (scope != null)

scope.Remove(itemToDelete);

}
