Expanded State
If the Columns or Rows section contains several data items, the Pivot column and row headers are arranged in a hierarchy and make up column and row groups.
You can collapse and expand row and column groups using the 
and 
buttons. However, the current expanded state of column and row groups do not save in the dashboard definition. If necessary, you can specify the default expanded state using the Initial State button on the Design ribbon tab of the Pivot Tools contextual tab set.
This button invokes the popup menu that allows you to select whether column and row groups should be collapsed or expanded by default.
To specify the expanded state of groups in code, use the following properties:
| Property | Description |
|---|---|
| PivotDashboardItem.AutoExpandColumnGroups | Gets or sets whether column field values are expanded or collapsed by default in the current PivotDashboardItem. |
| PivotDashboardItem.AutoExpandRowGroups | Gets or sets whether row field values are expanded or collapsed by default in the current PivotDashboardItem. |
