How to create Button_Click() Event for Bootstrap Button?

Question

Bootstrap login form is below:

<form class="form-vertical login-form" runat="server" action="~/Default.aspx">
    <label class="control-label visible-ie8 visible-ie9">User Name</label>
        <input class="m-wrap placeholder-no-fix" type="text" placeholder="UserName" name="username"/>
    <label class="control-label visible-ie8 visible-ie9">Password</label>
        <input class="m-wrap placeholder-no-fix" type="password" placeholder="Password" name="password"/>
    <button type="submit" class="btn green pull-right" aria-pressed="undefined">
    Log In <i class="m-icon-swapright m-icon-white"></i>
    </button>            
</form>

When the button is clicked, I want to create the connection to the database. So, I need to have sth like this:

protected void (ButtonName)_Click(object sender, EventArgs e)
{
    string connStr = "Initial Catalog=LoginCheck; Data Source=MYCOMPUTER; User id=sa; password=000000;";
    SqlConnection conn = new SqlConnection(connStr);
    conn.Open();
    ...
} 

But it doesn't work like ASP.NET. If I double-click on the button when I am designing, it's not taking me to code behind. Please put me in the right direction!

In ASP.Net, you want to use Server control if you want to post back.

Most of the time, <form> tag is located inside Master Page, so you cannot style it easily.

Here is an example -

<form id="form1" runat="server">
    <div class="form-vertical login-form">
        <asp:Label runat="server" ID="UsernameLabel"
            AssociatedControlID="UserNameTextBox"
            CssClass="control-label visible-ie8 visible-ie9">User Name
        </asp:Label>
        <asp:TextBox runat="server" ID="UserNameTextBox"
            CssClass="m-wrap placeholder-no-fix" />

        <asp:Label runat="server" ID="PasswordLabel"
            AssociatedControlID="PasswordTextBox"
            CssClass="control-label visible-ie8 visible-ie9">Password
        </asp:Label>
        <asp:TextBox runat="server" ID="PasswordTextBox"
            CssClass="m-wrap placeholder-no-fix" />

        <asp:LinkButton runat="server" ID="SubmitLinkButton"
            CssClass="btn btn-default pull-right" 
            OnClick="SubmitLinkButton_Click">
            Log In <i class="m-icon-swapright m-icon-white"></i>
        </asp:LinkButton>
    </div>
</form>
