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?
