All you need to use UpdatePanel.
Here is a example

<form id="form1" runat="server">
<asp:scriptmanager runat="server" id="ScriptManager1" xmlns:asp="#unknown">
<asp:updatepanel runat="server" id="UpdatePanel1" xmlns:asp="#unknown">
<contenttemplate>
<asp:dropdownlist runat="server" id="DropDown1" autopostback="true">
<asp:listitem text="DropDown1Item1" value="DropDown1Value1">
<asp:listitem text="DropDown1Item2" value="DropDown1Value2">
<asp:listitem text="DropDown1Item3" value="DropDown1Value3">



</form>
   
You are obviously just learning ASP.NET. I recommend learning MVC instead, it's better.

If you set AutoPostback to false, your control won't cause a postback.
   
Set dropdown AutoPostBack to false

AutoPostBack="false"

<asp:DropDownList ID="DropDownList1" AutoPostBack="false" runat="server">
    </asp:DropDownList>
