DotNet: '' Could not be set on Property ''

• This error seems to be sprinkled all across google and all across the
  newsgroups however there do not appear to be any solidified answers.
  
  Here is my scenario.
  I have a Web User Control that contains several properties that are of a
  custom class.
  This Class Contains multiple properties some of which include Arrays
  (say SqlParameter) for example.
  
  My Markup should look something like. I am having major designer
  difficulties however both of which result in the infamous error " '' Could
  not be set onproperty ''" whichin this case is an empty value on the
  FillList property.
  I have tried various combos of putting PersistChildren and ParseChildren to
  no avail
  
  <cc2:WebCustomControl1 id="WebCustomControl11" runat="server">
  
  <FillList CommandName="asfsadf" ParameterName="sdafas">
  
  <Parameters>
  
  <cc3qlParameter ParameterName="...Retail"></cc3qlParameter>
  
  </Parameters>
  
  </FillList>
  
  </cc2:WebCustomControl1>
  
  The Property Fill list is marked as
  Bindable(true),
  
  Category("SQL Properties"),
  
  PersistenceMode(PersistenceMode.InnerProperty),
  
  NotifyParentProperty(true),
  
  DesignerSerializationVisibility(DesignerSerializat ionVisibility.Content)]
  
  public DataParameters FillList
  
  {
  
  get { return gFillList; }
  
  set { gFillList = value; }
  
  }
  
  My structure is marked as such and the collection in question
  [TypeConverter(typeof(ExpandableObjectConverter)),
  
  Browsable(true),
  
  RefreshProperties(RefreshProperties.Repaint),
  
  Serializable(),
  
  ToolboxItem(false)]
  
  public class DataParameters
  
  {
  
  [PersistenceMode(PersistenceMode.InnerProperty) ,
  
  DesignerSerializationVisibility(DesignerSerializat ionVisibility.Content)]
  
  public ArrayList Parameters
  
  {
  
  get { return gParameters; }
  
  set { gParameters = value; SetParameters(value); }
  
  }
  
  }

  2. Illes can be used as a sex-neutral pronoun, like English 'they'. ,

  3. Because you were baptized into Christ and united with Him, crucified with him so that you died with him, now you can live in him. ,
