Remarks
Unlike custom painting applied by handling the PivotGridControl.CustomDrawCell event, appearances customized via the CustomAppearance event are used when the pivot grid is printed.
The CustomAppearance event fires for each pivot grid cell and allows you to customize the appearance of cells dynamically (depending on their contents, position, values of other cells, etc). Use the event parameter to identify the processed cell.
Important
Do not change cell values, modify the control’s layout, or change the control’s object model in the events used for custom control painting. Actions that update the layout can cause the control to malfunction.
To customize the appearance settings, use the event parameter’s PivotCustomAppearanceEventArgs.Appearance property.
To access event data while an asynchronous operation is being performed, use a thread-safe event parameter returned by the PivotCustomAppearanceEventArgs.ThreadSafeArgs property. To learn more, see Asynchronous Mode.
Example
The following example shows how to customize the appearance of specific cells via the PivotGridControl.CustomAppearance event.
In this example, custom appearance settings (the yellow background and bold font) are applied to a cell if it meets the following conditions:
- It belongs to an “ExtendedPrice” data field.
- It’s not displayed within total rows or columns.
- It’s value is larger than 1000.
The following image demonstrates code execution:
using DevExpress.XtraPivotGrid;
private void pivotGridControl1_CustomAppearance(object sender, PivotCustomAppearanceEventArgs e) {
if (e.DataField == fieldExtendedPrice && e.ColumnValueType == PivotGridValueType.Value
&& e.RowValueType == PivotGridValueType.Value) {
if (e.Value != null && (decimal)e.Value > 1000) {
e.Appearance.BackColor = Color.Yellow;
e.Appearance.FontStyleDelta = FontStyle.Bold;
}
}
}
