Passing a value to another page

[Mike P]

When you are passing a value to another page, and will need access to it
throughout the page and on any postbacks, what is the best way to store
it? By making it a variable accessible to the whole page, or by putting
it in the ViewState?


Thanks,

Mike

Store it in the ViewState. Keeping in a page-wide variable will not get the
value on postbacks.

Hi Mike,

In .NET 1.0/1.1 you can choose between QueryString, Session or
Server.Transfer. I recommend Session (it's just a matter of taste). In .NET
2.0 you use the PostBackUrl property on your controls. By setting the
PostBackUrl="/My2Page.aspx" in your Button tag the user will, when clicked,
be redirected to the My2Page.aspx in which you can access your values using
Request.Form.

Best regards,
