Before calling the cell.GetActionButton() method, you have to make sure that the specified action is already added to the container. You can do this using the cell.IsActionAdded() method. The code will be something as follows:
+--------------+
MedicalViewerActionType type = new MedicalViewerActionType();
MedicalViewerMultiCell cell = _medicalViewer.Cells[0] as MedicalViewerMultiCell;
MedicalViewerMouseButtons MouseButtom = MedicalViewerMouseButtons.Left;
bool Added = true;

try
{

type = MedicalViewerActionType.Alpha;
Added = cell.IsActionAdded(type);
if (Added)
{
if (MouseButtom == cell.GetActionButton(type))
{
MessageBox.Show(type.ToString() + " , " + MouseButtom.ToString());
}
}

type = MedicalViewerActionType.AnnotationAngle;
Added = cell.IsActionAdded(type);
if (Added)
{
if (MouseButtom == cell.GetActionButton(type))
{
MessageBox.Show(type.ToString() + " , " + MouseButtom.ToString());
}
}

type = MedicalViewerActionType.AnnotationArrow;
Added = cell.IsActionAdded(type);
if (Added)
{
if (MouseButtom == cell.GetActionButton(type))
{
MessageBox.Show(type.ToString() + " , " + MouseButtom.ToString());
}
}

type = MedicalViewerActionType.AnnotationAudio;
Added = cell.IsActionAdded(type);
if (Added)
{
if (MouseButtom == cell.GetActionButton(type))
{
MessageBox.Show(type.ToString() + " , " + MouseButtom.ToString());
}
}

type = MedicalViewerActionType.AnnotationButton;
Added = cell.IsActionAdded(type);
if (Added)
{
if (MouseButtom == cell.GetActionButton(type))
{
MessageBox.Show(type.ToString() + " , " + MouseButtom.ToString());
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
+--------------+

If the problem persists, please tell me what is the error that you get?
And what is the function the shows the error?
