Remarks
Use the IsSummaryFooter property to determine which nodes are to be involved in the summary value calculations. The list below explains which nodes must be visited depending on whether the footer summary or group summary value is calculated.
- If the group summary value is to be calculated, you must visit each node from the collection specified by the GetCustomSummaryValueEventArgs.Nodes parameter.
- If the total summary is calculated and the TreeListColumn.AllNodesSummary property is set to false, all required nodes are also transmitted via the GetCustomSummaryValueEventArgs.Nodes parameter.
- If the total summary value is to be calculated and the TreeListColumn.AllNodesSummary property value is true, you must visit each node within the control. This can be done be means of the nodes iterator that can be accessed via the TreeList.NodesIterator property. Please refer to this property’s description for details.
