Please help! - How do I create a group in .NET?

[Anonymous]

I am trying to add a group of objects to a group so that they can be selected as a unit. Here is my code. After this, when I select one of the slabs that is supposed to be in this group, it shows that nothing is grouped. What am I doing wrong?



Handle GroupMiniPanel()

{

Handle groupHandle = new Handle(0);

using (Transaction trans = HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction())

{

Database db = HostApplicationServices.WorkingDatabase;

DBDictionary groupDictionary = (DBDictionary)trans.GetObject(db.GroupDictionaryId, OpenMode.ForWrite,false);



string curLayer = AutodeskTransactionWrapper.GetCurrentLayer();

/////////////////////////////////////////////////

string miniPanelGroupDescription = string.Format("{0}_Group", curLayer);

groupHandle = groupDictionary.SetAt(_miniPanelGroup.Description, _miniPanelGroup).Handle;

//Add all of the minipanel items to the group

_miniPanelGroup.Append(_miniPanelArea.ObjectId);

for (int ii = 0; ii < _miniItems.Count; ii++)

{

ObjectId objId = HostApplicationServices.WorkingDatabase.GetObjectId(false, _miniItems[ii], 0);

_miniPanelGroup.Append(objId);

}

trans.AddNewlyCreatedDBObject(_miniPanelGroup, false);

trans.Commit();

}

return groupHandle;

}

Never mind. I got it

This line:

trans.AddNewlyCreatedDBObject(_miniPanelGroup, false);

should be

trans.AddNewlyCreatedDBObject(_miniPanelGroup, true);
