Can someone please help me with why this button is not working, I've tried putting it in <for id="" runat="server">, but then I get the error: A page can have only one server-side Form tag.

When the button is clicked nothing happens.

<%@ Page Language="C#" MasterPageFile="~/train.master" AutoEventWireup="true" validateRequest="false" 
CodeFile="TrainStationTutorial.aspx.cs" Inherits="TrainStationTutorial" Title="Admin | Tutorial" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <link href="style2.css" rel="stylesheet" type="text/css" />

<div id="main">
    <center>
       <object width="740" height="207" >
            <param name="movie" value="admin_menu.swf" />
            <embed src="images/admin_menu.swf" width="960" height="170" />
        </object>
    
        <h2>Admin | Tutorial</h2>
        <br />
        <div class="about">

                    <asp:TextBox ID="titleText" runat="server" CssClass="inputtext" />
                </div>

                </div>

    {
        messageLabel.Text = "Working";

I'm actually confused because the code snippet you've provided doesn't appear to have anything 'out of the ordinary' to it that I can see from first glance. Coupled with the fact that you have NO form tag that I can see, I'm not sure why you'd be getting the error that you can only have 1 form tag.

The last time I got the error "A page can have only one server-side Form tag." it was because I had a braindead moment and forgot how to separate content with panels and tried to do it with forms :twisted:

That being said... having 0 form tags may cause issues with trying to run ASP.Net server side scripting ;)

Can you have a look at the master page, maybe I'm missing something. I've tried different machines and same thing.

I could be missing something, or the fact that it's 2:45am and I'm about ready to pop off to bed could be influencing the clarity of my thinking.

That being said, I'm also not an "expert" so much as I'm good at finding the answers I need as I need them while I'm coding :twisted:

I say all this so you can take my next bit in context as having a 50/50 chance of being a total crock 'o sh*t hehe

Personally, I'm used to the <form> tags encompassing all of the interactive (read: asp.net) components within my pages. I'm also used to every <form> tag that's related to ASP.Net components having an id. When I look at your code it looks like you have a login content segment which has an enclosed form segment but that you also have a separate contentplaceholder segment which I will assume relates to your earlier code segment where there are form elements that are not in any way encapsulated within a form element.

Beyond that bit of speculation, I can't help you but maybe I'll have more luck in the morning if you're still having issues then :)

Your button controls are outside form tag . Try adding inside it. It will work.

I guess we have already discuss about similar topic here

Glad you got it sorted :) Was the problem based on what was suggested above or something else? I'm just curious.

Ok, I basically put a form tag in the master page for all the content, if you look at my master page I've only got a form tag for the login, Which does not apply to the ContentPlaceHolder.

Hi

You can refer the following code.

loginButton.Attributes.Add("onclick", "window.showModalDialog('/MyWebsite/login.aspx', null, 'status:no; dialogWidth:360px; dialogHeight:229px; help:no; scroll:no; menubar:no; resizable:no')");

It will help you to solve the issue of button not working.
