How to Save Data without Page Reloading on Dropdown SelectedIndexChanged Event

I am trying to update a DataTable on selection Index Changed event of DropdownList.

What I want is when I select/change dropDownList Item, the Selected Value should be saved into the database without Page refresh(without AutoPostback).

You will need to set AutoPostback to true.
But you can use an update panel to do a partial PostBack and not refresh the complete page.

See here

Use it like this:

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" ChildrenAsTriggers="true" >      
  <ContentTemplate>
    <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"  onselectedindexchanged="DropDownList1_SelectedIndexChanged">
      <asp:ListItem>item 1</asp:ListItem>
      <asp:ListItem>item 2</asp:ListItem>
    </asp:DropDownList>
  </ContentTemplate>
</asp:UpdatePanel>
