aspx_beginners thread: problem with chapter 3 beginning asp.net using c# ( passing variable to another aspx page)
Hi,
I have some problems with the example given in chapter 3 Beginning ASP.net
using C#. When i run the holidaypage.aspx, error occured as written in the
browser as follow:
Exception Details: System.Web.HttpException: Control 'FullName' of
type 'TextBox' must be placed inside a form tag with runat=server.
After i put the runat="server" inside the form tag, there was no error but
when the submit button was pressed, the value from the form seem like not
passing to the second aspx page (holidayresponse.aspx). It just stay on
the same page. When i view the source in the browser, i found out that the
form tag generated as below
<form name="_ctl0" method="post" action="holidaypage.aspx" id="_ctl0">
has the action attribute that link to the same holidaypage.aspx and not
holidayresponse.aspx. I think that's why all the value from the form is
not passing to holidayresponse.aspx. Does anyone has any idea to overcome
this problem of passing value to another aspx page. Thank you.
Mathew
