Hi,
I created a radrichtextbox with word processor. On the QuickAccessToolBar, the save button is defined as,
                        <telerik:RadRibbonButton telerik:RadRichTextBoxRibbonUI.RichTextCommand="{Binding Path=SaveCommand}" Size="Small" SmallImage="/Telerik.Windows.Controls.RichTextBoxUI;component/Images/MSOffice/16/save.png" Text="Save" />

The event handler for this button is defined by "{Binding Path=SaveCommand}". Where is SaveCommand (I assume it be a function)?

If I want to redefine the event handler for this button, how to specify it?  Thanks.

York

Hello York Zhang,

The SaveCommand that this command is bound to is defined in the Commands property of RadRichTextBox. You can notice how the DataContext of RadRichTextBoxRibbonUI is bound to the commands property of the RadRichTextBox instance, e.g.

<telerik:RadRichTextBoxRibbonUI DataContext="{Binding Path=Commands, ElementName=richTextBox}" ... >

You can refer to this forum thread for more information and a demo on creating custom commands and wiring RadRichTextBoxRibbonUI to work with them.
