The WebDrillDown retention period is used to determine how long the popup information is maintained on the client-side after it is retrieved.
By default, WebDrillDown will store this information indefinitely or until the page is re-loaded.
To specify a retention period appropriate for your web application, you can set the property below.
This sets a five second retention period.
After this time, the popup information will be discarded and the latest information will be retrieved when it is needed:
WebDrillDown.RetentionPeriod = 5; // seconds
Displaying any of the popup menus after a five second wait time will demonstrate this re-loading by displaying the loading image and text string.
In this sample the WebDrillDown is allowing you to select a breed of dog, organized by common categories.
