You can do this manually to your button in .aspx page by adding OnClick=”Button1_Click”:

<asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" />

then in your code-behind .aspx.cs (press F7 while in .aspx in Visual Studio) write:

protected void Button1_Click(object sender, EventArgs e)
{
}

or for .aspx.vb

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Button1_Click(sender, e)

'Some other codes

End Sub

Now when the button is clicked, the code in Button1_Click gets executed.
