Properties

AllowHtml

Boolean: Returns or sets a value indicating that the control can display HTML in the Text property. (Default: False)

Newlines (CRLF) are converted to <BR/> when AllowHtml is false, or when AllowHtml is true and the text doesn't contain any HTML.

AllowMarkdown

Boolean: Returns or sets a value indicating that the control can display markdown text as HTML in the Text property. (Default: False)

Anchor

AnchorStyles: Returns or sets the edges of the container to which a control is bound and determines how a control is resized with its parent. (Default: Top, Left)

AutoEllipsis

Boolean: Returns or sets whether the ellipsis character (...) appears at the right edge of the label, denoting that the text extends beyond the size of the label. (Default: False)

AutoSize

Boolean: Returns or sets a value that indicates whether the control resizes based on its contents. (Default: False)

Since 3.5.6 Auto sizing behavior in the Label control is slightly different from other controls. When the label is a child of a standard container (i.e. Panel, Form, Page, GroupBox) and it's anchored to the right, auto sizing grows or shrinks the label's width preserving the left position. When the label is a child of a container with a custom LayoutEngine (i.e. FlexLayoutPanel, FlowLayoutPanel, TableLayoutPanel) the auto sizing behavior is the same as all other controls. You can change the default behavior using the AppContext switch "LabelSelfSize". See System.AppContext to learn how to set the switch. In code, you can set it in a static Program constructor:


class Program {
  static void Program() {
    AppContext.SetSwitch("LabelSelfSize", false);
  }
}

AutoToolTip

Boolean: Returns or sets whether a tooltip is displayed when the text extends beyond the size of the label. (Default: False)

The auto tooltip is set on the browser using the title attribute managed by the browser, does not use the themed tooltip managed by Wisej.NET.

BorderStyle

BorderStyle: Indicates the border style for the control. (Default: None)

CharacterCasing

CharacterCasing: Returns or sets the case of the text to display to the user. (Default: Normal)

Command

DialogResult

SelfSize

Boolean: Returns or sets whether the label resize itself when AutoSize is true and it's in a container using the default layout engine: i.e.: Panel, Form, Page, GroupBox, UserControl.Since 3.5.6 (Default: True)

When self sizing is active (default for standard containers) an auto sizing label will always grow to the right side, even when anchored right, preserving it's left position. This is the default behavior in WinForms applications.

SelfSizeDefault

Boolean: EXPERIMENTAL: Default value for the SelfSize property.Since 3.5.6

The default is true. You can set the value by code or using AppContext switches: AppContext.SetSwitch("LabelSelfSize", false);

Text

String: Returns or sets the text associated with this control. (Default: "")

Newlines (CRLF) are converted to <BR/> when AllowHtml is false, or when AllowHtml is true and the text doesn't contain any HTML.
