make Serializable or create custom TypeConverter ?

[Christian]

Hi,

I try to assign a variable of type WebControls.Button to ViewState as
follows

ViewState["m_ballSelected"] = m_ballSelected;

but get an error -->

"The type 'System.Web.UI.WebControls.Button' must be marked as Serializable
or have a TypeConverter other than ReferenceConverter to be put in
viewstate."

How do I mark this intrinsic-control as Serializable ?
or else ...
I guess I have to create a custom TypeConverter for my Button then ?
How do I do that ?
any code samples someone can recommend me ?

thanks

chris

Just add EnableViewState="True" as an attribute to the
button in the aspx file.
