Using the variable in the code behind

[trickytr]

Hi everyone,

My problem is using the value of a variable from the codebehind page in an html tag.
I have got the html code on default.aspx for example
and there is a variable in default.aspx.vb called THISPAGE.
And in the HTML code I want to use this string value in a form tag like this:

<form method="post" action="<% =THISPAGE %>">

But when I run the page I got an error message that THISPAGE should be declared although I have declared it in the codebehind page.

Thanks a lot.

How is THISPAGE Declared? Make sure it's public

I made the scope of variable Public in default.aspx.vb before but still I got the error message that it is not declared.

You shouldn't really set attributes by including script tags. The correct way to do it would be to:

1) Add a reference to your Form in the code-behind. e.g. if you Form tag had an ID of Form1 then add:

    Public WithEvents Form1 As System.Web.UI.HtmlControls.HtmlForm

2) On your Page Load, use Attributes.Add to add the action attrribute. e.g.

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
        Dim strPage As String = "Page2.aspx"
        Form1.Attributes.Add("action", strPage)
    End Sub

Thank you for your answer it really helped.
But I have got an another problem. I want to use vb code and html on the same page without using an codebehind page.
But I have to add this codes

Imports System.Data.SqlClient
Imports System.Web.Security

And I could not do this on the aspx page it only worked on the codebehind page.Is there any way to import these in the aspx page without using code behind.

Thanks a lot

<% @ import namespace="System.Data"%>
<% @ import namespace="System.Data.SqlClient"%>

Add these code at the top of your page...
