XRCrossTab.GenerateLayout() Method

Generate the Cross Tab cells based on the specified fields.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v24.2.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

public void GenerateLayout()

VB.NET

Public Sub GenerateLayout

Remarks

To define the Cross Tab layout in code, add data source fields to the Cross Tab’s RowFields, ColumnFields and DataFields collection. Then, call the GenerateLayout method to generate Cross Tab cells based on the specified fields and fill the Cells collection. See the XRCrossTab class description for more information about cell types and purposes.

Example

The following code sample creates a new SqlDataSource, creates a report with the XRCrossTab control at runtime, and binds the Cross Tab control to data:

C#

using DevExpress.DataAccess.ConnectionParameters;
using DevExpress.DataAccess.Sql;
using DevExpress.XtraPrinting;
using DevExpress.XtraReports.UI;
using DevExpress.XtraReports.UI.CrossTab;
using System;
using System.Drawing;
using System.Windows.Forms;
// ...
private XtraReport CreateReport() {
    // Creates a blank report.
    XtraReport crossTabReport = new XtraReport() {
        VerticalContentSplitting = VerticalContentSplitting.Smart,
        HorizontalContentSplitting = HorizontalContentSplitting.Smart
    };

    // Creates a detail band and adds it to the report.
    DetailBand detail = new DetailBand();
    crossTabReport.Bands.Add(detail);

    // Creates a cross tab and adds it to the Detail band.
    XRCrossTab crossTab = new XRCrossTab();
    detail.Controls.Add(crossTab);
    crossTab.PrintOptions.RepeatColumnHeaders = true;
    crossTab.PrintOptions.RepeatRowHeaders = true;

    // Creates a data source.
    SQLiteConnectionParameters connectionParameters = new SQLiteConnectionParameters(@"|DataDirectory|\nwind.db", "");
    SqlDataSource ds = new SqlDataSource(connectionParameters);

    // Creates an SQL query to access the SalesPerson view.
    SelectQuery query = SelectQueryFluentBuilder.AddTable("SalesPerson")
                .SelectColumn("CategoryName")
                .SelectColumn("ProductName")
                .SelectColumn("Country")
                .SelectColumn("FullName")
                .SelectColumn("Quantity")
                .SelectColumn("ExtendedPrice").Build("SalesPerson");
    ds.Queries.Add(query);

    // Binds the cross tab to data.
    crossTab.DataSource = ds;
    crossTab.DataMember = "SalesPerson";

    // Generates cross tab fields.
    crossTab.RowFields.Add(new CrossTabRowField() { FieldName = "CategoryName" });
    crossTab.RowFields.Add(new CrossTabRowField() { FieldName = "ProductName" });
    crossTab.ColumnFields.Add(new CrossTabColumnField() { FieldName = "Country" });
    crossTab.ColumnFields.Add(new CrossTabColumnField() { FieldName = "FullName" });
    crossTab.DataFields.Add(new CrossTabDataField() { FieldName = "Quantity" });
    crossTab.DataFields.Add(new CrossTabDataField() { FieldName = "ExtendedPrice" });
    crossTab.GenerateLayout();
// ...
    // Adjusts the generated cells.
    foreach(var c in crossTab.ColumnDefinitions) {
        // Enables auto-width for all columns.
        c.AutoWidthMode = DevExpress.XtraReports.UI.AutoSizeMode.GrowOnly;
    }

    foreach(XRCrossTabCell c in crossTab.Cells) {
        if(c.DataLevel == 1 && c.RowIndex != 2) {
            // Adjusts format string for the "Extended Price" cells.
            c.TextFormatString = "{0:c}";
        }
    }


    // Assigns styles to the cross tab.
    crossTab.CrossTabStyles.GeneralStyle = new XRControlStyle() { 
        Name = "Default",
        Borders = BorderSide.All,
        Padding = new PaddingInfo() { All = 2 }                
    };
    crossTab.CrossTabStyles.DataAreaStyle = crossTab.CrossTabStyles.TotalAreaStyle = new XRControlStyle() {
        Name = "Data",
        TextAlignment = TextAlignment.TopRight
    };
    crossTab.CrossTabStyles.HeaderAreaStyle = new XRControlStyle() {
        Name = "HeaderAndTotals",
        BackColor = Color.WhiteSmoke
    };
    return crossTabReport;
}
