Passing a variable from page to page using ASP.NET (C #) without using QueryString

Question

Look for advice on passing variables from page to page without using QueryString. Web crawlers such as google fall into search queries found in the URL. I am trying to get away from using it. Is there any other suggested method for passing variables? I thought about using session variables, but it's just for simple passing a variable from page to page, and they will not always be the same. Any ideas?

On the other hand, I cannot do this using forms. I am using a homepage with a form embedded in the homepage, as well as content pages. If microsoft has not updated it so you can use multiple forms on the same page.

Answer 1

You can look at ASP.NET Routing (which can be done without MVC) - then you can have a data path, but without a query string; as are the paths (which are actually MVC but the same logic applies).

Unable to use forms - you can just use jQuery or similarly to create forms on the fly.

Answer 2

What about ASP.NET session storage?

You can store material in a session on your page and retrieve it from there on your second page.

Answer 8

On the main page there is a text box and a button like ...

<asp:TextBox ID="input" runat="server"></asp:TextBox>
<asp:Button ID="Bt" runat="server" Text="Button" PostBackUrl="~/Getvalue.aspx" />

Now you can get the value TextBoxfrom the previous page toGetValue.aspx

• On aspx page

<%=Request.Form["input"]%>

or

• In the code file

TextBox1.Text = Request.Form["input"]; (TextBox1 is in  "GetValue.aspx" )
