Show Help Button and Change its Image

The purpose of this tutorial is to demonstrate how to show the help button and change its image.

Show the Help Button

In order to manage the visibility of the help button, you should use RadRibbonView's HelpButtonVisibility property as demonstrated in Examples 1 and 2.

Example 1: Setting the HelpButtonVisibility in xaml

<telerik:RadRibbonView x:Name="xRibbonView" HelpButtonVisibility="Visible"/> 

Example 2: Setting the HelpButtonVisibility in code

xRibbonView.HelpButtonVisibility = Visibility.Visible; 
xRibbonView.HelpButtonVisibility = Visibility.Visible; 

The default value of the HelpButtonVisibility property is Visibility.Collapsed.

To set a different icon from the default one, you should use the HelpButtonImageSource property.

<telerik:RadRibbonView x:Name="xRibbonView" HelpButtonImageSource="myHelpButton.png"/>
