In my winform app. I have to serialize an object that inherit from TabPage object.
I got a message that I have to mark the TabPage as [Serializable] too.
How can I do this?
[Serializable] 
    partial class myTabPage : TabPage
    {
        public string ContainerTableTag;
        public bool showAlways;
        public bool showForAllChildren;
        public bool showForChild;
       
        public myTabPage()
        {
           InitializeComponent();           
        }
    }

Open in new window

What information do you need to serialize inside of the tabpage control itself? Do you know this before-hand or only at runtime?

Hi,
The information I need is some boolean and strings varaibles in myTabPage.
The values accepted only at runtime.
I can try to  seperate the varaibles to another class, however I would like to know if there ia an option to serialize the control as it is, or not.
Thanks.

You can't really serialize/deserialize controls as-is because of the nature of the beast. Controls have things that change at run time like windows handles, etc. and things that change at design time such as you changing the width of that textbox in the designer. Serialization is not all "all-or-nothing" approach though so I can understand what you want to do. You're trying to serialize what makes sense...your properties such as
        public string ContainerTableTag;
        public bool showAlways;
        public bool showForAllChildren;
        public bool showForChild;
..and that's a perfectly good approach. Unfortunately, since this isn't a control you have total control over because of your inheritance of TabPage you can't (easily) inject a [Serializable] attribute into the TabPage control itself because, obviously you don;t have the source code.

What you can do rather than writing a separate class to contain your properties is inherit the ISerializable interface in your myTabPage and by implementing that interface you can "choose" what and how you want to serialize in your class (and leave the rest alone)

http://www.codeproject.com/KB/cs/objserial.aspx

is a good first-look at using ISerializable and should help you out with the few properties that you need to serialize. Let me know if you need any further assistance with the sample.

Happy Coding
