Property Value
Type: System.Int32The number of items displayed on each page of the view returned from the Data and DataView properties, or 0 to indicate there is no paging.
When PageSize equals 0, paging is turned off and the number of items exposed by the Data property is unlimited. When PageSize is a non-zero value, the number of entities loaded with each Load operation is limited as well, using server-side paging. 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 PageSize 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.
