  Your requirement is not totally clear but you can redirect in the event.

      <asp:DropDownList ID="DropDownList1" runat="server" 
          autopostback="true" 
          OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
          <asp:ListItem Text="Select" Value="0"></asp:ListItem>
          <asp:ListItem Text="Option" Value="1"></asp:ListItem>
      </asp:DropDownList>

      protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
      {
          Response.Redirect("~/index.aspx?action=changed");
      }

  Hi kengkit,

  Accroding to your description,as far as I think,you could add parameters in the Redirect.

  Since you don't post your codes to us,I create a demo.

  If you have other problems,I suggest you could tell us more details of you requirment and post your full codes to us.It will help us to solve your problems.

  More details,you could refer to below codes:

  <div>
              <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
                  <asp:ListItem Value="1" Text="AA"></asp:ListItem>
                  <asp:ListItem Value="2" Text="BB"></asp:ListItem>
              </asp:DropDownList>
          </div>

  Code-Behind:

   Protected Sub DropDownList1_SelectedIndexChanged(sender As Object, e As EventArgs)
          Response.Redirect(Request.Url.AbsolutePath + "?action=changed")
  
      End Sub

  Result：

  

  Best regards,
