Problems getting TextBox value in Code Behind

tounet · Apr 28, 2012

I'm having problems getting a Code Behind page to get the value of a Visable="False" TextBox and then displaying it in a Label. Here is my ASPX: <%@Page Language="vb" Src=http://aspmessageboard.com/archive/index.php/"TestForm.vb" Inherits="TestForm"%> <HTML> <HEAD> <title>TestForm</title> </HEAD> <body> Press the Button! <form id="Form1" method="post" runat="server"> <asp:TextBox ID="strDBID" Visible="False" Runat="server>123</TextBox> <asp:Button ID="submit" Text="Submit" Runat="server /> </form> <asp:Label ID="msg" Runat="server" /> </body> </HTML> My Code Behind Code: Imports System Imports System.Web Imports System.Web.UI Imports System.Web.UI.WebControls Public Class TestForm Inherits Page Public strDBID As TextBox Public msg As Label Sub Submit_Click(Sender As Object, E As EventArgs) msg.Text = Server.HtmlEncode(strDBID.Text) End Sub End Class After clicking Submit, nothing happens. Any Ideas!!!! My ultimate goal is not to actually have it display the information in a label. This is only to see if I can get the value over to the Code Behind. What I want to actually do is pass the hidden value over to the Code Behind and then grab that information, put it in a variable that I can use in a SQL statement on the Code Behind. If you have any ideas or suggestions on how to accomplish either one of these or both I would really appreciate your input. Thanks, David Check out the RegisterHiddenField method of the Page class: http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemwebuipageclassregisterhiddenfieldtopic. aspYou seem to be missing a declaration for the button. Try opening the page with VStudio and double clicking the button in the designer, this should add the declaration and bring you to the code view. Inherits Page Public strDBID As TextBox Public msg As Label >>>Protected WithEvents submit As System.Web.UI.WebControls.Button -A
