Question

i have a master page and a child aspx page, coneected to each other. the master page has the form in it.

How can i send all the checkbox values (checkbox.text = [email protected]) to the next page? there are lots of these values that need to pass to nex tpage.

Use Button.PostBackUrl to change the page which the button posts to, and then on the target page, use Page.PreviousPage to get a reference to the source page (and therefore its controls).

By default you can use Page.PreviousPage.FindControl(...) to find a control on the source page by ID, then cast it to a checkbox and retrieve its values. You can also specify the type of the previous page with a <%@ PreviousPageType %> directive, and then access the previous page's public properties.
