Property Value

Type	Description
Style	A Style object that is the style applied to individual text elements in the total summary item.

Remarks

The TotalSummaryElementStyle property is in effect if the DataViewBase.ShowTotalSummary property is set to true.

Use the TotalSummaryElementStyle property to define the text element style for all the summaries within a view. To define the text element style for an individual summary item, use the summary item’s SummaryItemBase.TotalSummaryElementStyle property.

Example

The code sample below demonstrates how to change the appearance of total summary items depending on the summary value. This code sample uses the DXBinding mechanism to simplify the trigger definition.
