I search on internet but did not find any best solution, i found one way, where you need to code html tags like
<input type='text'> ... etc etc
and retrieve that value on another page as
Request.Form["name of input text field"];
W3Schools -ASP Forms and User Input
exists any better way to retrieve that post value??
ASP.NET WebForms has support for cross-page posting. Read http://msdn.microsoft.com/en-us/library/ms178139.aspx and http://msdn.microsoft.com/en-us/library/ms178140.aspx for more information.
Example:
WebForm1.aspx:
Note the asp:button has its PostBackUrl property set.
WebForm2.aspx:
Note that I’ve added the PreviousPageType directive here.
WebForm2.aspx.cs: (Codebehind)
