Sets or returns an integer representing the position of the slide to which the data will be bound during a PowerPointTemplate.BindData method call. DataBindingProperties.Slide allows users to import different data values onto slides that use the same data markers. The slide is specified using the 0-based index of the slide within the presentation.
DataBindingProperties.Slide defaults to -1 which indicates that the data import is not scoped to a particular slide.
