{
    //Update the property grid with the new control/section properties
    this.SelChangePropGrid();
            
    if(this._controlAdded)  //Control is newly added
    {
        //Add item to ComboBox and PropGrid
        this._isCboDirty = true;
        this._controlAdded = false;
    }
        
    if(this._controlDeleted)  //Control is newly deleted
    {
        this._isCboDirty = true;
    }

    if(this._sectionAdded)  //Section is newly added
    {
        this._isCboDirty = true;
    }

    if(this._sectionDeleted)  //Section is newly deleted
    {
        this._isCboDirty = true;
    }
}
