Collapses all columns and rows in Pivot Grid Control asynchronously. Allows you to specify custom actions to be performed after this operation is completed.
public void CollapseAllAsync( AsyncCompletedHandler asyncCompleted )
Public Sub CollapseAllAsync( asyncCompleted As AsyncCompletedHandler )
A AsyncCompletedHandler delegate referencing a method that should be executed after the operation is completed.
The CollapseAllAsync method is asynchronous. It starts executing the related operation in a background thread, and immediately returns control. The primary UI thread is not blocked, allowing the application to continue responding to end-user actions. For more information about the asynchronous mode, see Asynchronous Mode.
To expand all columns and rows asynchronously, use the PivotGridControl.ExpandAllAsync method.
