Syntax
public class MatrixHeaderDescriptor : MatrixDescriptor, IFRSerializable
Remarks

The MatrixHeaderDescriptor class is used to define one header element of the matrix (either the column element or row element). The key properties are Expression, Sort and Totals.

To set visual appearance of the element, use the TemplateCell property. To set visual appearance of the "total" element, use the TemplateTotalCell property.

The collection of descriptors used to represent the matrix header is stored in the MatrixObject.Data.Columns and MatrixObject.Data.Rows properties.

Constructors

MatrixHeaderDescriptor()

Initializes a new instance of the MatrixHeaderDescriptor class with default settings.

Declaration
public MatrixHeaderDescriptor()

MatrixHeaderDescriptor(String)

Initializes a new instance of the MatrixHeaderDescriptor class with specified expression.

Declaration
public MatrixHeaderDescriptor(string expression)
Parameters
Type Name Description
System.String expression

The descriptor's expression.

MatrixHeaderDescriptor(String, SortOrder, Boolean)

Initializes a new instance of the MatrixHeaderDescriptor class with specified expression, sort order and totals.

Declaration
public MatrixHeaderDescriptor(string expression, SortOrder sort, bool totals)
Parameters
Type Name Description
System.String expression

The descriptor's expression.
SortOrder sort

Sort order used to sort header values.
System.Boolean totals

Indicates whether to show the "total" element.

MatrixHeaderDescriptor(String, Boolean)

Initializes a new instance of the MatrixHeaderDescriptor class with specified expression and totals.

Declaration
public MatrixHeaderDescriptor(string expression, bool totals)
Parameters
Type Name Description
System.String expression

The descriptor's expression.
System.Boolean totals

Indicates whether to show the "total" element.

Properties

PageBreak

Gets or sets a value indicating that the page break must be printed before this element.

Declaration
public bool PageBreak { get; set; }
Property Value
Type Description
System.Boolean
Remarks

Page break is not printed before the very first element.

Sort

Gets or sets the sort order of header values.

Declaration
public SortOrder Sort { get; set; }
Property Value
Type Description
SortOrder
Remarks

This property determines how the values displayed in this element are sorted. The default sort is ascending.

SuppressTotals

Gets or sets a value that determines whether it is necessary to suppress totals if there is only one value in a group.

Declaration
public bool SuppressTotals { get; set; }
Property Value
Type Description
System.Boolean

TemplateTotalCell

Gets or sets the template cell bound to the "total" element of this descriptor.

Declaration
public TableCell TemplateTotalCell { get; set; }
Property Value
Type Description
TableCell
Remarks

This property may be useful to change the "Total" text by something else.

note

Before using this property, you must initialize the matrix descriptors by calling the BuildTemplate() method.

Examples

This example shows how to change the "Total" element.

MatrixObject matrix;
matrix.Data.Rows[0].TemplateTotalCell.Text = "Grand Total";
matrix.Data.Rows[0].TemplateTotalCell.Fill = new SolidFill(Color.Green);

TemplateTotalColumn

Gets or sets the template column bound to the "total" element of this descriptor.

Declaration
public TableColumn TemplateTotalColumn { get; set; }
Property Value
Type Description
TableColumn
Remarks

This property is for internal use; usually you don't need to use it.

TemplateTotalRow

Gets or sets the template row bound to the "total" element of this descriptor.

Declaration
public TableRow TemplateTotalRow { get; set; }
Property Value
Type Description
TableRow
Remarks

This property is for internal use; usually you don't need to use it.

Totals

Gets or sets a value indicating that this element has associated "total" element.

Declaration
public bool Totals { get; set; }
Property Value
Type Description
System.Boolean
Remarks

To access the matrix cell that is bound to the "Total" element, use the TemplateTotalCell property. It may be useful to change the "Total" text by something else.

Examples

This example shows how to change the "Total" text of the total element.

MatrixObject matrix;
matrix.Data.Rows[0].TemplateTotalCell.Text = "Grand Total";

TotalsFirst

Gets or sets the value indicating whether the total values must be printed before the data.

Declaration
public bool TotalsFirst { get; set; }
Property Value
Type Description
System.Boolean

Descriptor to assign values from.
Overrides

Serialize(FRWriter)

Serializes the object.

Declaration
public override void Serialize(FRWriter writer)
Parameters
