Office-like WPF Tooltip for Hyperlinks


You can have Office-like tooltips for the hyperlinks displayed in RichTextBox control in WPF. First thing to note is enabling the hyperlinks in RichTextBox by setting IsDocumentEnabled property. Then, we will bind the ToolTip property of the hyperlink to its NavigateUri property to be able to use it in the new DataTemplate of the ToolTip. The DataTemplate is defined so that when RichTextBox is editable the tooltip will display “Ctrl + Click to follow link” along with the navigation address, but in read-only mode the helper text will be “Click to follow link”.
