XRCrossTab.DataSource Property

SECURITY NOTE

Deserializing a report layout from untrusted resources may create security issues. Serializable System.Object properties that contain custom type values are not (de)serialized automatically. Review the following help topic for information on how to (de)serialize custom type values: Reporting — Safe Deserialization.

Specifies the Cross Tab control’s data source. If it is empty, the report data source is used.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v23.2.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

[DefaultValue(null)]
[SRCategory(ReportStringId.CatData)]
public object DataSource { get; set; }

VB.NET

<SRCategory(ReportStringId.CatData)>
<DefaultValue(Nothing)>
Public Property DataSource As Object

Property Value

Type	Default	Description
Object	null	An object that provides data to the Cross Tab control.

Remarks

Use the DataSource and DataMember properties to provide a data source to the XRCrossTab control individually.

Note

If no data source is specified for the XRCrossTab control (the DataSource property is null), the data source is obtained from the XtraReportBase.DataSource property of the report that contains an XRCrossTab control.

At design time, you can access the DataSource property in the Cross Tab control’s smart tag. Expand this property’s drop-down list and click Add Report Data Source.

Follow the steps in the invoked Data Source Wizard to configure a data source. Once you complete the wizard, the DataSource and DataMember properties are set.

Note

Do not use dots in the data source name since the report engine uses them to separate the names of different data items (data source, table, relation, field, etc.)

A data source’s fields become available in the Field List. Drop these fields onto cross-tab areas to define the control layout.

The Cross Tab control supports three field areas:

• Rows (RowFields collection) - defines the row headers;

• Columns (ColumnFields collection) - defines the column headers;

• Data (DataFields collection) - defines fields against which to calculate summaries.

Note

If you place the Cross Tab control in the Detail band, ensure that a report’s DataSource property is not set. Otherwise, the Cross Tab data is printed as many times as there are rows in the report data source.

See the Bind Reports to Data documentation section for more information about data sources.

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;

// ...
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("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;
}
