How to Cancel Editing?

FrancoisChartrand

Hi,

Is it possible add logic to decide whether or not (based on some conditions) if it is allowed to start editing a particular graphic and cancel edition if needed? I would like to do something like this:

public MyClass()
{
    MyEditor.EditStarting += OnEditStarting;
    MyEditor.EditCompleted += OnEditCompleted;
}

private void OnEditStarting(object sender, Editor.EditEventArgs e)
{
    if (!IsEditAllowed(e.Graphic))
    {
        e.Cancel = true;
    }
    else
    {
        ...
    }
}

private void OnEditCompleted(object sender, Editor.EditEventArgs e)
{
    ...
}

private bool IsEditAllowed(Graphic graphic)
{
    ...
}

The only operation you can really do with point geometry is to move them. This is why Editor.EditVertices does not make sense to activate on a graphic with point geometry.

I agree. It doesn't make sense to use EditVertices for points. But then, what is the proper way for moving points? Are you planning to add an Editor.Move command for points?

What you can do is only activate EditVertices for polyline and polygon geometries. And handle the move on point geometries by providing offset to its X,Y values using MouseMove and MouseLeftButtonUp events or you can listen to the next MouseClick that sets the new location of the point geometry.

I'll do that as a workaround 😞
Thank you
