Button kontrolune basdığımızda Click ve Command olayları gerçekleşecektir.
Bu metotlardan birini kullanmamız yeterlidir.
OnClick metodu ile;
<script runat="server">
void Button1_Click(Object sender, EventArgs e)
{
Response.Write("Merhaba Çamlıca");
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">

<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Butona Bas" OnClick="Button1_Click" />
</div>
</form>
