ASP.NET/HTML: HTML button’s onClick property inside ASP.NET (.cs)

I just wanna find out if there’s a way to put my onClick event inside .cs:

<button type="submit" runat="server" id="btnLogin" class="button" onclick="btnLogin_Click();">

where Login_Click() should be inside .cs:

protected void btnLogin_Click(object sender, EventArgs e)
{
    // do something
}

Please do take note that I will not use ASP.NET button here, and that I will not put my Login_Click() event inside .html/.aspx so I can’t ‘expose’ my codes. Any suggestions?

Method 1

You can do that on any server control and this button is made a server control by defining “runat=server“. The problem is probably in your definition of the event:

<button ... runat="server" ... onServerClick="btnLogin_Click" />

You don’t need “();” there…

Apart from that can you explain why you don’t use the <asp:Button> here because I don’t really see a problem with that…

Method 2

You’ll want to use the onServerClick. There’s an example of how to do that on MSDN:

<button id="Button1" OnServerClick="Button1_OnClick" runat="server">
    Click me!
</button>


protected void Button1_OnClick(object Source, EventArgs e) {
    // secret codes go here
}

Method 3

btnLogin.Click += new EventHandler( btnLogin_Click );

will assign the btnLogin_Click event handler to the button’s Click event.

however, I would point out that assigning a handler in the markup of the aspx page does not “expose your codes”, as the HTML rendered down to the client doesn’t have any of that information in it.

Method 4

I know it’s late but i lost so much time on this problem. I was setting InnerHtml of a div with buttons. You need to add type=”submit” to your button if you want it to work.

Method 5

It’s late but for someone out there: Apply UseSubmitBehavior="False". Example

<button type="submit" runat="server" UseSubmitBehavior="False" type="button" id="btnLogin" class="button" onclick="btnLogin_Click();">
