If you want to display the value of one textbox on another page then
QueryString will be a good option. But if you need to display the values of multiple textboxes (controls) then you can use the
PostBackUrl property of button. With this you would be able to access all the controls of first page on next page with
PreviousPage property.
Please refer the following link to know more about the
PostBackUrl property of button.
