Examples

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.

using System;
using System.Globalization;
using System.Windows.Forms;
using DevExpress.XtraPivotGrid;

namespace XtraPivotGrid_HidingColumnsAndRows {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();
            pivotGridControl1.CustomFieldValueCells += 
                new PivotCustomFieldValueCellsEventHandler(pivotGrid_CustomFieldValueCells);
        }
        void Form1_Load(object sender, EventArgs e) {
            PivotHelper.FillPivot(pivotGridControl1);
            pivotGridControl1.DataSource = PivotHelper.GetDataTable();
            pivotGridControl1.BestFit();
        }

        // Handles the CustomFieldValueCells event to remove
        // specific rows.
        protected void pivotGrid_CustomFieldValueCells(object sender,
                             PivotCustomFieldValueCellsEventArgs e) {

            PivotGridControl pivot = sender as PivotGridControl;
            if (pivot.DataSource == null) return;
            if (radioGroup1.SelectedIndex == 0) return;

            // Iterates through all row headers.
            for (int i = e.GetCellCount(false) - 1; i >= 0; i--) {
                FieldValueCell cell = e.GetCell(false, i);
                if (cell == null) continue;

                // If the current header corresponds to the "Employee B"
                // field value, and is not the Total Row header,
                // it is removed with all corresponding rows.
                if (object.Equals(cell.Value, "Employee B") &&
                    cell.ValueType != PivotGridValueType.Total)
                    e.Remove(cell);
            }
        }
        void pivotGridControl1_FieldValueDisplayText(object sender, 
                                    PivotFieldDisplayTextEventArgs e) {
            PivotGridControl pivot = sender as PivotGridControl;
            if (e.Field == pivot.Fields[PivotHelper.Month])
            {
                e.DisplayText = CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName((int)e.Value);
            }
        }
        void radioGroup1_SelectedIndexChanged(object sender, EventArgs e) {
            this.pivotGridControl1.LayoutChanged();
        }        
    }
}
