How to Freeze/Thaw (AutoCAD commands) in edrawing viewer API Control

Hi,

I'm trying to view a drawing (.DWG) created in AutoCAD 2014 through my VB.NET program using eDrawing Viewer and trying to on/off layers.

However, i'm not able to view the layers which are freezed when using AutoCAD.

Is there a way to unfreeze a layer in eDrawing Viewer API contol. I dont find any properties to on/off freeze layer.

Please provide me an Solution

Thanks
