PivotGridControl.ChangeFieldExpandedAsync(PivotGridFieldBase, Boolean, AsyncCompletedHandler) Method

Expands or collapses all values of the specified field asynchronously. Allows you to specify custom actions to be performed after this operation is completed.

Namespace:DevExpress.XtraPivotGrid
Assembly:DevExpress.XtraPivotGrid.v17.1.dll

Expanded Syntax

Parameters

field
Type: PivotGridFieldBase
A DevExpress.XtraPivotGrid.PivotGridFieldBase descendant that specifies the field whose values should be expanded/collapsed.
expand
Type: Boolean
true to expand field values; false to collapse them.
asyncCompleted
Type: AsyncCompletedHandler
A DevExpress.XtraPivotGrid.AsyncCompletedHandler delegate, referencing a method that should be executed after the operation is completed.

Expanded Remarks

The ChangeFieldExpandedAsync 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 collapse or expand all values of a particular field synchronously, use the DevExpress.XtraPivotGrid.PivotGridFieldBase.CollapseAll and DevExpress.XtraPivotGrid.PivotGridFieldBase.ExpandAll methods, respectively.

To collapse or expand a specific field value, use the CollapseValueAsync and ExpandValueAsync methods, respectively (or the CollapseValue and ExpandValue methods, to do this synchronously).

Field values can be collapsed and expanded by end-users, if the field's DevExpress.XtraPivotGrid.PivotGridFieldOptions.AllowExpand property is set to true.
