Add dropdownlist and button to aspx page:

ASP.NET

<asp:dropdownlist id="ddlTime" runat="server">
    <asp:listitem text="startofday" value="1"></asp:listitem>
</asp:dropdownlist>

<asp:button id="btnAdd" runat="server" text="SignIn" onclick="DisplayAllItem" xmlns:asp="#unknown" />

Add following code in your code-behind file:

C#

protected void DisplayAllItem(object sender, EventArgs e)
{
    ddlTime.Items.Add(new ListItem("Lunchbreak", "2"));
	ddlTime.Items.Add(new ListItem("teabreak", "3"));
	ddlTime.Items.Add(new ListItem("dinnerbreak", "4"));
	ddlTime.Items.Add(new ListItem("other", "5"));
	ddlTime.Items.Add(new ListItem("endofday", "6"));
}
