Gets a value that indicates whether the specified field is excluded when the ListFieldIterator is rendered.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Because a field is excluded if either its InternalName or Title is included in ExcludeFields, when you create custom fields, you should not only keep each Title unique and each Internal Name unique; you should also ensure that no Title is the same as any other field's Internal Name. Otherwise, you might exclude two fields when you want to exclude only one.
Even if field is not listed in ExcludeFields, the default implementation of returns true in certain circumstances when it would be undesirable to render the field. For example, if the field appears somewhere else on the page anyway, it is not be rendered by the ListFieldIterator. Some of the other factors that the method takes into account are in the following list.
