How do I iterate the datareader in a child window and return the values to the parent

[srithil]

Hai I am new to asp.net.

I am opening a child window by a popup.I trigger an event by a buttonnext,I make a database connection and select records and store it in my datareader .I try to pass the values through the window.opener method to the parent window.How do I iterate the values in the datareader when i press the button again.when i press the button again the parent fields has to be populated with the new record values.Here is my code.
Also i am not able to pass the value for a checkbox.how do i pass a value to the checkbox if i am storing as true or false in the database,so that the checkbox gets checked in my parent window.

Anybody please help.I am stuck with this.
