PivotGridControl.CollapseValueAsync(Boolean, Object[]) Method

Collapses the specified column or row asynchronously.

Namespace: DevExpress.Xpf.PivotGrid

Assembly: DevExpress.Xpf.PivotGrid.v24.1.dll

NuGet Package: DevExpress.Wpf.PivotGrid

Declaration

C#

public Task<bool> CollapseValueAsync(
    bool isColumn,
    object[] values
)

VB.NET

Public Function CollapseValueAsync(
    isColumn As Boolean,
    values As Object()
) As Task(Of Boolean)

Parameters

Name	Type	Description
isColumn	Boolean	true to collapse a column; false to collapse a row.
values	Object[]	An array of field values that identify the column/row to be collapsed.

Returns

Type	Description
Task<Boolean>	An asynchronous operation that returns true in case of success.

Remarks

The CollapseValueAsync 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.

If you need to perform specific actions after this operation is completed, use another overload of the CollapseValueAsync method that takes the asyncCompleted parameter, and pass a delegate that performs the required actions as this parameter.

Consider the following PivotGridControl:

To collapse ‘1995’ within “Aniseed Syrup”, do the following:

C#

pivotGrid.CollapseValueAsync(true, new object[] { "Aniseed Syrup", 1995 });

The image below shows the result:

To collapse a column or row synchronously, use the PivotGridControl.CollapseValue method.

To expand a column or row, use the PivotGridControl.ExpandValueAsync (asynchronous) or PivotGridControl.ExpandValue (synchronous) method.
