How to: Hide Individual Rows and Columns
The following example demonstrates how to hide particular rows and columns by handling the CustomFieldValueCells event. In this example, the event handler iterates through all row headers and removes rows that correspond to the "Employee B" field value, and that are not Total Rows.
| C#:Data.cs |
using System.Data;
using DevExpress.XtraPivotGrid;
namespace XtraPivotGrid_HidingColumnsAndRows {
public static class PivotHelper {
public const string Employee = "Employee";
public const string Widget = "Widget";
public const string Month = "Month";
public const string RetailPrice = "Retail Price";
public const string WholesalePrice = "Wholesale Price";
public const string Quantity = "Quantity";
public const string Remains = "Remains";
public const string EmployeeA = "Employee A";
public const string EmployeeB = "Employee B";
public const string WidgetA = "Widget A";
public const string WidgetB = "Widget B";
public const string WidgetC = "Widget C";
public static void FillPivot(PivotGridControl pivot) {
pivot.Fields.Add(Employee, PivotArea.RowArea);
pivot.Fields.Add(Widget, PivotArea.RowArea);
pivot.Fields.Add(Month, PivotArea.ColumnArea).AreaIndex = 0;
pivot.Fields.Add(RetailPrice, PivotArea.DataArea);
pivot.Fields.Add(WholesalePrice, PivotArea.DataArea);
pivot.Fields.Add(Quantity, PivotArea.DataArea);
pivot.Fields.Add(Remains, PivotArea.DataArea);
foreach (PivotGridField field in pivot.Fields) {
field.AllowedAreas = GetAllowedArea(field.Area);
}
pivot.OptionsView.RowTotalsLocation = PivotRowTotalsLocation.Near;
pivot.OptionsView.ShowRowGrandTotals = false;
pivot.OptionsView.ColumnTotalsLocation = PivotTotalsLocation.Far;
pivot.OptionsDataField.Area = PivotDataArea.ColumnArea;
pivot.OptionsDataField.AreaIndex = 1;
}

switch (area) {

}
