How i can pass the values from one page to another????????

Salman Iqbal · Sep 22, 2003

Dear Support team

I have binded a list to logins to the dropdownlist control. And Thanks God
it worked fine.

Suppose database structure is like

********************************
ID NAME

1 Salman
2 Richards
3 Marry

**********************************

But my problem is i want to pass the ID to the next page. When
the users click any login for e.g salman, the page should submit and id(for
e.g 1) should be passed to next page.

I don't have any idea... How it can be done???
Will any one help???

Regards
Salman

There is a type within the System.Web.UI.WebControls called HyperLink - it
may be what you want.

If you want to maually assemble a page with data, you could do something
like the below. On the other hand, ASP.NET ships with a set of Data-bound
controls, and you can directly map data from databases to these Web UI
controls. A Datagrid, for example, may provide a more automatic way of
getting what you want.

Why don't you use some thing like this ....on the form that opens after the
login page

<%
Dim strUserName
Dim intUserID

strUserName = Request.Form("txtUserName")
intUserID = Request.Form("txtUserID")

%>

txtUserName and txtUserID are both text boxes on your login page. Or in you
case it would be the drop down list box. Just make sure you give the
controls on the login page a name and id.

Search your help on Request.Form it will give you all the info you need...
