CannotTrackChangeEventArgs Class — TX Text Control .NET for WPF

Description

The CannotTrackChangeEventArgs class provides data for the CannotTrackChange event. This event determines how to handle a change of the document that cannot be added to the list of tracked changes. Complex table layout changes, such as deleting a table column or merging table cells cannot be tracked. The default handling shows a MessageBox asking the end-user whether the change of the document should be performed. Using the Handled and the Cancel property the default handling can be changed.

Syntax

public class CannotTrackChangeEventArgs : CancelEventArgs

Public Class CannotTrackChangeEventArgs
    Inherits CancelEventArgs

Examples

The following example uses CannotTrackChangeEventArgs.Handled while handling CannotTrackChange.

textControl.CannotTrackChange += (_, e) =>
{
    e.Handled = true;
};

AddHandler textControl.CannotTrackChange,
    Sub(sender, e)
        e.Handled = True
    End Sub

Properties

Property	Description
Cancel	Gets or sets a value indicating whether the change of the document should be performed. If the property value is true, which is the default value, the operation is canceled. If the property value is false, the document is changed.
DefaultMessage	Gets the default message for the user. If a subscriber does not handle the event, this message is displayed with a message box asking the end-user whether the change of the document should be performed.
Handled	A subscriber can set this property to true to indicate that he has handled the event. In this case the default handling is suppressed. The default handling shows a MessageBox asking the end-user whether the change of the document should be performed. The default value of this property is false.
