Hello,

I have a user control that is a search form.  Within this user control, I have a radiobuttonlist that will most likely select the same value every time.  Can I tie that into personalization through code, or somehow within the user control, maybe through a custom property?

Thanks.

You can implement the IPersonalizable interface and manage your custom properties in those functions. Here's a basic example:

using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

namespace CustomControls
{
    public class SimpleIPersonalizableWebPart : WebPart, IPersonalizable
    {
        private TextBox txtBox;

        public SimpleIPersonalizableWebPart()
        {
            txtBox = new TextBox();
            this.Title = "Default SimpleIPersonalizableWebPart Title";
        }

        protected override void CreateChildControls()
        {
            txtBox.ID = "txtId";
            txtBox.Text = "Default textbox Text";
            Controls.Add(txtBox);
        }

        void IPersonalizable.Load(PersonalizationDictionary state)
        {
            if (Controls.Count == 0 || state == null)
                return;

            PersonalizationEntry entry = state["TextBoxTextValue"];
            if (entry != null)
            {
                object obj = entry.Value;
                if (obj.GetType().Name == "String" && Controls[0].GetType().Name == "TextBox")
                {
                    ((TextBox)Controls[0]).Text = (string)obj;
                }
            }
        }

        void IPersonalizable.Save(PersonalizationDictionary state)
        {
            foreach (Control control in Controls)
            {
                if (control.GetType().Name == "TextBox")
                {                
                    PersonalizationEntry entry = new PersonalizationEntry(((TextBox)control).Text, PersonalizationScope.User);
                    state.Add("TextBoxTextValue", entry);
                }
            }
        }

        bool IPersonalizable.IsDirty
        {
            get
            {
                return true;
            }
        }
    }
}
