RowCollection.CollapseGroups(Int32) Method

Collapses all row groups starting from the specified level.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v24.1.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

C#

void CollapseGroups(
    int level
)

VB.NET

Sub CollapseGroups(
    level As Integer
)

Parameters

Name	Type	Description
level	Int32	A Int32 value that specifies the grouping level starting from which row groups should be collapsed.

Remarks

If a worksheet has multiple grouping levels, you can use the CollapseGroups method to collapse row groups starting at the specified and subsequent levels. For example, the following code collapses all the groups except the first level:

C#

worksheet.Rows.CollapseGroups(2);

VB.NET

worksheet.Rows.CollapseGroups(2)

If the level parameter is less than or equal to 1, the CollapseGroups method collapses all the row groups. You can also collapse all row groups in a worksheet using the RowCollection.CollapseAllGroups methods.

If the level parameter is greater than the maximum grouping level specified in a worksheet, the CollapseGroups method expands all the row groups. Another way to expand all row groups in a worksheet at once is to call the RowCollection.ExpandAllGroups method.
