Adding a persistable TextBox property

[Jason Barnett]

I've developed a control that inherits from TextBox. I created a property that gets rendered into a HiddenField, which is altered by javascript at run time. The HiddenField is initialized during OnInt, and added to the controls collection during CreateChildControls. Also, I've overridden the LoadPostData method to retrieve the property value based on the HiddenField's ID.

All works well, but I'm concerned about the last step (retrieving the value during LoadPostData). I'm curious if there is a way to get ASP.NET will restore the ViewState of the child control for me. Is anyone aware of a better way to handle this?
