从html5按钮onclick事件调用serverside方法

Question

我做了一个测试应用程序,其中控件是html5控件.我有2个文本框和一个html5按钮.我想在html5按钮上触发onclick事件,并且通过onclick事件调用的方法在服务器端.

我试过但它没有工作.任何人都可以帮我从html5按钮调用服务器端方法.我发布了我的代码.

//clientside code
<form id="form1" runat="server">
    <div>
        First name:<input type="search" name="searchfield" placeholder="enter your name"
            autofocus="on" required="required" pattern="[A-z]" />
        E-mail:
        <input type="email" name="emailfield" placeholder="enter emailid" />

        <button onclick="btnSave_click" value="Click to Save" id="btnSave" runat="server" autofocus="autofocus" formtarget="_parent">
            Click to Save</button>
    </div>
</form>

// server side code
protected void btnSave_Click(object sender, EventArgs e)
{
    string name = Request.Form["searchfield"];
    string emailid = Request.Form["emailfield"];
    string dob = Request.Form["bday"];

    SqlConnection cn = new SqlConnection();
    cn.ConnectionString = "Data Source=CP1106\\SQLEXPRESS;Initial Catalog=Testdb;User ID=sa;Password=pwd";

    cn.Open();

    string query = "INSERT INTO TestTable(name, email) VALUES(@name, @email)";

    SqlCommand cmd = new SqlCommand(query,cn);
    cmd.Parameters.Add("@name", name);
    cmd.Parameters.Add("@email", emailid);
    // cmd.Parameters.Add("@bday", dob);

    cmd.ExecuteNonQuery();

    cn.Close();
    BindGrid();
}
