Two common methods for passing parameters between webpages: querystring and session.

We are working on ASP. net web pages, it is inevitable to transfer parameters between different web pages. Below are two common methods to transfer parameters between web pages: the efficiency of parameter transfer is not discussed here. I personally prefer to use session transfer and release it immediately after use. It is very convenient.

Sending Page code:<Font Style="Background-color: # FFFF00"><Font Style="Background-color: # FFFF00">

Private   Sub imagebutton1_click () Sub Imagebutton1_click () Sub imagebutton1_click () Sub Imagebutton1_click ( Byval Sender As System. Object , Byval E As System. Web. UI. imageclickeventargs) Handles Imagebutton1.click
' Passing parameters through querystring or in session

' The following section is transmitted using querystring.
' Dim URL as string
' Url = "../search/localtemp. aspx. aspx? & Search = OK"
' If txtenterprisename. Text <> "" then
' Url = URL + "& E =" + txtenterprisename. Text
' End if
' If txtaddress. Text <> "" then
' Url = URL + "& A =" + txtaddress. Text
' End if
' If ddlprovice. selectedvalue <> "select Province" then
' Url = URL + "& P =" + ddlprovice. selectedvalue
' End if
' If ddlcity. selectedvalue <> "select city" then
' Url = URL + "$ c =" + ddlcity. selectedvalue
' End if
' If url = "../search/singledetailed. aspx? & Search = OK "then
' 'Error message
' End if
' Response. Redirect (URL)

' Next we use session to pass
Session ( " E " ) = Txtenterprisename. Text
Session ( " A " ) = Txtaddress. Text
Session ( " P " ) = Ddlprovice. selectedvalue
Session ( " C " ) = Ddlcity. selectedvalue
' Server. Transfer ()
Response. Redirect ( " ../Search/localtemp. aspx " )
End sub

Code of the Acceptance page: < Font Style = " Background-color: # FFFF00 " > < Font Style = " Background-color: # ffffff " > </ Font > < Font Style = " Background-color: # FFFF00 " >  


Private   Sub page_load () Sub Page_load ( Byval Sender As System. Object , Byval E As System. eventargs) Handles   Mybase . Load

' Put user code to initialize the page here
If   Not Ispostback Then
' If quesring is used
' Dim enname as string = request. querystring ["E"]
Dim Ename As   String
Dim Eaddress As   String
Dim Eprovice As   String
Dim Ecity As   String
Ename = Session ( " E " ). Tostring
Eaddress = Session ( " A " ). Tostring
Eprovice = Session ( " P " ). Tostring
Ecity = Session ( " C " ). Tostring
' ----
' Your code
' -----
' When you use finish
Session. Remove ( " E " )
Session. Remove ( " C " )
Session. Remove ( " A " )
Session. Remove ( " P " )
End   If
End sub </ Font > </ Font >
