Button click is not working in usercontrol Umbraco
I started to build a website using Umbraco and I noticed that button click events (and probably other events) are not working.

I created simplest usercontrol with one button, added it to a page, When I debug it the Page_Load is called (breakpoint being hit), but not button click.

The code is very standard, but here it is:

.aspx file
```
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="TestControl.ascx.cs" Inherits="usercontrols_TestControl" %>

<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
```
and code behind:
```
protected void Button1_Click(object sender, EventArgs e) {
    Label1.Text = "Button clicked!";
}
```
Where can be the problem?

Hi,

First thing to check - in your template, you need to have <form runat="server"> wrapping your macro/usercontrol

Hi Tom, thanks, yes I do have this tag in my Main.master, I have it inside my body tag so all content goes in it, something like this:

...

<body>

<form runat="server">

...

</form>

</body>

In fact I can't even add a the usercontrol to a page without it as I get this exception straight away:

Control 'ContentPlaceHolderDefault_Content_TestControl_2_Button1' of type 'Button' must be placed inside a form tag with runat=server.

Hmm, odd, it should be working...

How are you calling the usercontrol from the template? Is it wrapped in a macro or are you calling directly? Can you paste the code?

Yes, I use macro as usual,

<umbraco:Macro Alias="TestMacro" runat="server" />

In fact it was working earlier today, I was playing with membership provider and members, it suddenly stopped working. I can't figure out what I changed that could break it.

Ok, I solved part of the problem. I was adding <form runat="server"> to my parent template and adding macro to child template. After I moved <form runat="server"> to the child template and wrapped it around my macro it started to work.

Why it happens? Is it possible to add it once to master (parent) template. I'm sure I saw it working in another project.

Yes definetly possible. I always put my form tag on the master. You probably need to post your usercrontol and master pages so we can see. I presume you have copied across your compiled DLL.

It's became even more interesting, I can add <form runat="server"> to Main template but it has to be some specific place in the template.

So here is my Main template (I removed html to make it shorter):

<%@ Master Language="C#" MasterPageFile="~/umbraco/masterpages/default.master" AutoEventWireup="true" %>
<asp:Content ContentPlaceHolderID="ContentPlaceHolderDefault" runat="server">
<!doctype html>
<html dir="ltr" lang="en" class="no-js">
<head>
...
<asp:contentplaceholder id="Head" runat="server"></asp:contentplaceholder>
</head>
<body>


   <umbraco:Macro Alias="Header" runat="server" />
   <form runat="server"> 
<asp:contentplaceholder id="Content" runat="server"></asp:contentplaceholder>
...
      <umbraco:Macro Alias="MainNavigation" runat="server" />
...
   <asp:contentplaceholder id="PageBottom" runat="server"></asp:contentplaceholder>
</form>
</body>
</html>
</asp:Content>

and here is my child template where I place macro with button:

<%@ Master Language="C#" MasterPageFile="~/masterpages/Main.master" AutoEventWireup="true" %>
<asp:Content ContentPlaceHolderID="Content" runat="server">
   <umbraco:Macro Alias="TestMacro" runat="server" />
</asp:Content>

It looks like my Header macro prevents button click event from working, If i place <form runat="server"> above it it doesn't work, if below everything starts to work. Weird because it is mainly html which has one simle razor condition, here it is:

<header id="header" @if(@Model.NodeTypeAlias != "Homepage") { <text>class="sub"</text> }>
<div class="content">
    <h1 id="logo"><a href="/">Site name</a></h1>

    <form action="" method="" id="search">
      <p><input type="text" placeholder="search" /><input type="submit" value="submit" /></p>
    </form>

    <strong id="lang">
      <img src="/img/flag.jpg" alt="English - UK" />
      <em>English</em>
      <a href="#">Change</a>
    </strong>
</div>
</header>

Any ideas?

p.s. Sorry for the lack of formatting, don't know how to do it on this forum.

Hi,

I think it's because your Header macro has it's own <form> tag in it, and it's not valid to have nested <form> tags.

So I think you'll need to move the <form runat="server"> after the header macro, or remove the <form> element from your header macro.

Oh yes, of course this is the problem, I should have noticed it myself. Thank you very much, Tom.
