Hi,

I created a custom control, and encountered a dirty property value
persistence problem.
I created a property with a custom class type, call SQLSettings which
holds the SQL connection parameters, the class as follows:

public sealed class SQLSettings
{
       private string serverName;
       .......

       public SQLSettings()
       {
           this.serverName = string.Empty;
           ......
       }

       [NotifyParentProperty(true)]
       public string ServerName
       {
           get
           {
               return this.serverName;
           }
           set
           {
               this.serverName = value;
           }
       }
..................

And, I also created an mapping TypeConverter and UITypeEditor classes
to handle the design-time founctinality. The property I created in my
conbtrol as follows:

           [BrowsableAttribute(true)]
           [CategoryAttribute("Behavior")]
           [BindableAttribute(true)]
           [NotifyParentProperty(true)]
           [EditorAttribute(typeof(SQLSettingsUITypeEditor),
typeof(UITypeEditor))]

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]

           [TypeConverter((Type)typeof(SQLSettingsTypeConverter))]
           [PersistenceModeAttribute(PersistenceMode.InnerProperty)]
           public SQLSettings SQLSettingsData
           {
               get
               {
                   return this._sqlSettings;
               }
               set
               {
                   this._sqlSettings = value;
               }
           }

They all works fine when first set value to this property, I can see
the persisted data showed in .aspx file. When I go back to design view
and update the property value via my UITypeEditor, I can see the value
already updated in VS.NET properties browser. But when I turn to see
.aspx file in code view, I didn't see the dirty property value updated
in .aspx file. When I turn to design view, the updated property value
is lost, it remain keep the first persisted value.

How to solve this problem? Any idea?
Thank you for your kindly help.
