Hi indradeo,

Refer below sample.


<asp:DropDownList runat="server" ID="ddlMonths">



protected void Page_Load(object sender, EventArgs e)
    if (!this.IsPostBack)
        DateTime currentDate = DateTime.Now;
        List<ListItem> items = new List<ListItem>();
        items.Add(new ListItem
            Text = currentDate.AddMonths(-1).Month.ToString(),
            Value = currentDate.AddMonths(-1).Month.ToString()
        items.Add(new ListItem
            Text = currentDate.Month.ToString(),
            Value = currentDate.Month.ToString()
        ddlMonths.DataSource = items;
        ddlMonths.DataTextField = "Text";
        ddlMonths.DataValueField = "Value";


Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        Dim currentDate As DateTime = DateTime.Now
        Dim items As List(Of ListItem) = New List(Of ListItem)()
        items.Add(New ListItem With {
            .Text = currentDate.AddMonths(-1).Month.ToString(),
            .Value = currentDate.AddMonths(-1).Month.ToString()
        items.Add(New ListItem With {
            .Text = currentDate.Month.ToString(),
            .Value = currentDate.Month.ToString()
        ddlMonths.DataSource = items
        ddlMonths.DataTextField = "Text"
        ddlMonths.DataValueField = "Value"
    End If
End Sub
