//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"];
