Try this:

ClientSide:
Javascript:

JavaScript

<script language="javascript" type="text/javascript" >
     function validate() {
         if (document.getElementById('<%=DropDownList1.ClientID %>').value == "Select") {
             alert("Please Select!");
             document.getElementById('<%=DropDownList1.ClientID %>').focus();
             return false;
         }
     }
       
    </script>

Markup:

ASP.NET

<asp:button id="Button1" runat="server" text="Button" onclick="Button1_Click" onclientclick="return validate()"/>

ServerSide:
In .CS page:

C#

//Bind Dropdown
           DropDownList1.Items.Insert(00, "Select");
           DropDownList1.SelectedIndex = 0;

In button click event:

C#

if (ddl_DropDownList1.SelectedItem.Text != "Select")
{

}
  else
{
  //alert
}
