Assembly: RAYLASE.Marker.UndoRedo (in RAYLASE.Marker.UndoRedo.dll) Version: 2.19.0

Syntax

Copy

bool InUndoRedo { get; }

Property Value

Boolean

Remarks

This property is extremely useful to prevent undesired "Do" being executed. That could occur in the following scenario: event X causees a Do action and certain Undo / Redo action causes event X, i.e. Undo / Redo causes a Do action, which will render history in a incorrect state. So whenever Do is called, the status of InUndoRedo should aways be checked first. Example:

Copy

void SomeEventHandler() 
{
    if(!history.InUndoRedo) 
        history.Do(...);
}
