Properties

AutoFit

Gets or sets the text auto-fitting setting.

Default value is None.

This property is not applicable on a TextBox within a TableCell.

public TextAutoFit AutoFit { get; set; }
Public Property AutoFit As TextAutoFit
Property Value
TextAutoFit

The text auto-fitting setting.

AutoFitShrinkTextFontScale

Gets or sets the percentage of the original font size to which each TextRun in the TextBox is scaled when AutoFit is ShrinkTextOnOverflow.

Default value is 1 if AutoFit is ShrinkTextOnOverflow; otherwise, System.Double.NaN.

This property is not applicable on a TextBox within a TableCell.

public double AutoFitShrinkTextFontScale { get; set; }
Public Property AutoFitShrinkTextFontScale As Double
Property Value
System.Double

The percentage of the original font size to which each TextRun in the TextBox is scaled when AutoFit is ShrinkTextOnOverflow.

Remarks

In order to auto-fit text within a bounding box it is sometimes necessary to decrease the font size by a certain percentage. Using this property the font within a text box can be scaled based on the value provided. A value of 1 scales the text to 100%, while a value of 0.01 scales the text to 1%.

Exceptions
System.InvalidOperationException

Property AutoFitShrinkTextFontScale can be set only if property AutoFit is ShrinkTextOnOverflow.

System.ArgumentOutOfRangeException

Value is not between 0 and 1.

AutoFitShrinkTextLineSpaceReduction

Gets or sets the percentage amount by which the line spacing of each TextParagraph in the TextBox is reduced when AutoFit is ShrinkTextOnOverflow.

This property applies only to paragraphs with percentage line spacing.

Default value is 0 if AutoFit is ShrinkTextOnOverflow; otherwise, System.Double.NaN.

This property is not applicable on a TextBox within a TableCell.

public double AutoFitShrinkTextLineSpaceReduction { get; set; }
Public Property AutoFitShrinkTextLineSpaceReduction As Double
Property Value
System.Double

The percentage amount by which the line spacing of each TextParagraph in the TextBox is reduced when AutoFit is ShrinkTextOnOverflow.

Remarks

The reduction is applied by subtracting it from the original line spacing value. Using this property the vertical spacing between the lines of text can be scaled by a percent amount. A value of 1 reduces the line spacing by 100%, while a value of 0.01 reduces the line spacing by one percent.

Exceptions
System.InvalidOperationException

Property AutoFitShrinkTextLineSpaceReduction can be set only if property AutoFit is ShrinkTextOnOverflow.

System.ArgumentOutOfRangeException

Value is not between 0 and 1.

Centered

Gets or sets a value indicating the centering of the text box.

The way it works fundamentally is to determine the smallest possible "bounds box" for the text and then to center that "bounds box" accordingly. This is different than Alignment, which aligns the text within the "bounds box" for the text.

This property is compatible with all of the different kinds of VerticalAlignment.

Default value is false.

This member is currently not supported in PDF, XPS, and image formats.

public bool Centered { get; set; }
Public Property Centered As Boolean
Property Value
System.Boolean

true if the text box is horizontally centered; otherwise, false.

ColumnNumber

Gets or sets the number of columns of text in the bounding rectangle.

Default value is 1.

This property is not applicable on a TextBox within a TableCell.

This member is currently not supported in PDF, XPS, and image formats.

public int ColumnNumber { get; set; }
Public Property ColumnNumber As Integer
Property Value
System.Int32

The number of columns of text in the bounding rectangle.

Remarks

When applied to a TextBox this property takes the width of the bounding box for the text and divides it by the number of columns specified. These columns are then treated as overflow containers in that when the previous column has been filled with text the next column acts as the repository for additional text. When all columns have been filled and text still remains then the overflow properties set for this TextBox are used and the text is reflowed to make room for additional text.

Exceptions
System.ArgumentOutOfRangeException

Value is less than 1.

ColumnSpacing

Gets or sets the space between text columns when there is more than 1 column present in the TextBox.

Default value is 0.

This property is not applicable on a TextBox within a TableCell.

This member is currently not supported in PDF, XPS, and image formats.

public Length ColumnSpacing { get; set; }
Public Property ColumnSpacing As Length
Property Value
Length

The space between text columns when there is more than 1 column present in the TextBox.

Exceptions
System.ArgumentOutOfRangeException

Value is less than zero.

InternalMarginBottom

Gets or sets the bottom internal margin of the TextBox bounding rectangle within a Shape or a TableCell.

Default value is 0.05 inches.

public Length InternalMarginBottom { get; set; }
Public Property InternalMarginBottom As Length
Property Value
Length

The bottom internal margin of the TextBox bounding rectangle within a Shape or a TableCell.

Exceptions
System.ArgumentOutOfRangeException

Value is less than zero.

InternalMarginLeft

Gets or sets the left internal margin of the TextBox bounding rectangle within a Shape or a TableCell.

Default value is 0.1 inches.

public Length InternalMarginLeft { get; set; }
Public Property InternalMarginLeft As Length
Property Value
Length

The left internal margin of the TextBox bounding rectangle within a Shape or a TableCell.

Exceptions
System.ArgumentOutOfRangeException

Value is less than zero.

InternalMarginRight

Gets or sets the right internal margin of the TextBox bounding rectangle within a Shape or a TableCell.

Default value is 0.1 inches.

public Length InternalMarginRight { get; set; }
Public Property InternalMarginRight As Length
Property Value
Length

The right internal margin of the TextBox bounding rectangle within a Shape or a TableCell.

Exceptions
System.ArgumentOutOfRangeException

Value is less than zero.

InternalMarginTop

Gets or sets the top internal margin of the TextBox bounding rectangle within a Shape or a TableCell.

Default value is 0.05 inches.

public Length InternalMarginTop { get; set; }
Public Property InternalMarginTop As Length
Property Value
Length

The top internal margin of the TextBox bounding rectangle within a Shape or a TableCell.

Exceptions
System.ArgumentOutOfRangeException

Value is less than zero.

TextDirection

Gets or sets the text direction.

Default value is Horizontal.

public TextDirection TextDirection { get; set; }
Public Property TextDirection As TextDirection
Property Value
TextDirection

The text direction.

VerticalAlignment

Gets or sets the vertical alignment of the text within an object such as a Shape or a TableCell.

Default value is Top.

public VerticalAlignment VerticalAlignment { get; set; }
Public Property VerticalAlignment As VerticalAlignment
Property Value
VerticalAlignment

The vertical alignment of the text within an object such as a Shape or a TableCell.

WrapText

Gets or sets a value indicating whether to wrap text in shape.

Default value is true.

This property is not applicable on a TextBox within a TableCell.

public bool WrapText { get; set; }
Public Property WrapText As Boolean
Property Value
System.Boolean

true if words are wrapped within the bounding rectangle; otherwise, false if words spill out without paying attention to the bounding rectangle boundaries.
