The default load setting is to show the first 500 items of a library/list. The dialog box will present a ‘Get All Items’ link if the number of items exceeds 500.
The number of items to be loaded in initially can be modified to any number suitable to your requirements.
To enable this feature use the <LocationContent> tag. The <LocationContent> tag attributes are detailed below:
<?xml version="1.0" encoding="UTF-8"?> <configuration> <locationContent action="delete"/> <locationContent firstPageResultsCount="250" action="insert"/> </configuration>
