ArcGIS Engine下怎么调出栅格图层属性框

通过下面的代码可以调出矢量图层的属性框，调出的栅格图层属性框却是空白一片请问我要如何改造代码才能调出栅格图层属性框

IFeatureLayer layer = axMapControl1.get_Layer(0) as IFeatureLayer;

IComPropertySheet comSheet = new ComPropertySheetClass();

comSheet.Title = "图层属性";

comSheet.ClearCategoryIDs();

comSheet.HideHelpButton = true;

UID pUID = new UIDClass();

comSheet.AddCategoryID(pUID);

ESRI.ArcGIS.Framework.IPropertyPage drawPage  = null;            

drawPage = new LayerDrawingPropertyPage() as ESRI.ArcGIS.Framework.IPropertyPage;

comSheet.AddPage(drawPage);

ESRI.ArcGIS.esriSystem.ISet pMySet = new ESRI.ArcGIS.esriSystem.SetClass();

pMySet.Add(layer);

pMySet.Reset();

comSheet.ActivePage = 0;

bool a = comSheet.EditProperties(pMySet, 0);
