Compile error

I get the following compile error.
Error 1 The name 'Roles' does not exist in the current context

In the ManagePhotoAlbum.aspx directory
protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
{
switch (e.Item.ItemType)
{
case ListViewItemType.DataItem:
Button deleteButton = (Button)e.Item.FindControl("DeleteButton");
deleteButton.Visible = Roles.IsUserInRole("Manager");
break;
}
}

Looks like you missed step 4 of the exercise on page 614.

Also, take a look at page 178 to see how to make VWD add the using statement for you.

Finally, when you post messages like these, can you please post the chapter and page number? Makes it easier for me to find stuff.

Cheers,

Have you checked the Roles is publicly invoked in your page class. If it is a static class, then please check whether you are having the reference for your class?
