ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Desktop.Mapping Namespace / TrayButton Class / HelpURI Property
Version

HelpURI Property (TrayButton)
Gets the DAML helpURI property of this TrayButton.
Syntax
public string HelpURI {get;}
Remarks

This is an optional property.

It is used only if ButtonType is TrayButtonType.PopupToggleButton

When this property is set and non-null, a Help button will be displayed in the popup header, and when clicked, opens the URI within the default browser.

If null (the default value) then the Help button will not be displayed.

Upon initially reading this DAML property, the URI string will be validated as an Absolute URI. If validation fails, then the help URI will be ignored, and no help button will be displayed.

Requirements

Target Platforms: Windows 11, Windows 10
