Property Value
Type: System.Int32The number of items to load in a single data loading operation, or 0 to indicate all items should be loaded.
When PageSize and LoadSize are both non-zero, entities will be loaded using the multiple of PageSize nearest LoadSize. This allows multiple pages to be loaded at once without loading partial pages.
Always specify a value for LoadSize that is less than or equal to any ResultLimit property configured on the DomainDataSource.
The following example shows a DomainDataSource control with the LoadSize property set to 30 and PageSize property set to 15.
