I'm using asp.net with c# in backcode. On my first page, I have a hyperlink with NavigateUrl ="Order.aspx?productId = " + ProductID . I want to transfer ProductID in Order.aspx file. So, how to get it in target file :Order.aspx.
I used a lable to display in Order.aspx file
string productId = Request.QueryString["productId"];
lblTest.Test = productId
But lblTest didn't display anything
Thanks.
You would read the QueryString values of the Request object.
string productId = Request.QueryString["productId"]; You'd have to parse it into an integer if that is what it is.
NavigateUrl ="Order.aspx?productId = " + ProductID You might also want to get rid of the spaces in your URL.
proudctId = might cause you problems. Debug the page and see what Request.QueryString["productId"] is returning.String value = Request.QueryString["productId"]; Its advisable that you verify whether Request.QueryString["productId"] is really present.
Use the request collection
string productId = Request["productId"]; Be careful what you do with this variable. E.g. don't store it directly in a database or append it to an inline query.
If ProductID is a server-side variable, use this: NavigateUrl = "Order.apx?productId = "<% =ProductID %>
Your code:
="Order.aspx?productId = " + ProductID; Remove the space My code:
="Order.aspx?productId=" + ProductID;
