I am curious, does anyone know how the visual studio saves the\nproperties you set at design time? I would like to do this at runtime\nso i'm curious.\n\nA note: I had a post eariler about setting a sub classed textbox user\ndefined property at runtime. I was losing the value on postback. I\nsubituted the variable with a call to the viewstate with the ID of the\ntextbox and the name of the property together. That worked, but i am\nconcerned about the the size of the viewstate. Any suggestions? Thanks.
