How to fill dropdownlist with months name using System.Globalization in asp.net

In this article I am going to explain how to fill dropdownlist with months name using System.Globalization in asp.net using C# and vb.net.

In the previous article I have explained how to get all countries list usingsystem.globalization and bind to dropdownlist in asp.net, how to print a webform (webpage) in asp.net using C# and VB.net, how to generate and display QRcode image using QR Code library in asp.net  and how to filter the record using Alphabets pager in asp.net.

Description:

System.Globalization namespace contains classes that define culture-related information, including language, country/region, calendars in use, and format patterns for dates, currency, and numbers, and sort order for strings.

 Implementation:

HTML Markup:

  <fieldset style="width:50%">

    <legend>Populate Dropdownlist with Months Names</legend>

    Select Country:<asp:DropDownList ID="ddlmonth" runat="server" AutoPostBack="true">

    <asp:ListItem Value="0">--Select--</asp:ListItem>

    </asp:DropDownList>

    </fieldset>

First of all import the namespace

C# code:

using System.Globalization;

VB.net Code:

Imports System.Globalization

Get month’s name

Create method to get month’s name and call the method page load.

C# code:

protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            GetMonthName();

        }

    }

public void GetMonthName()

    {

        try

        {

            DateTimeFormatInfo dtinfo = DateTimeFormatInfo.GetInstance(null);

            for (int i = 1; i <= 12; i++)

            {

                string monthname = dtinfo.GetMonthName(i);

                ddlmonth.Items.Add(new ListItem(monthname, i.ToString()));

            }

        }

        catch (Exception ex)

        { }

    }

 

  protected void ddlmonth_SelectedIndexChanged(object sender, EventArgs e)

    {

        Response.Write("<script>alert('Selected Month is : "+ ddlmonth.SelectedItem +"')</script>");

    }

VB.net Code:

  Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

        If Not IsPostBack Then

            GetMonthName()

        End If

    End Sub

    Public Sub GetMonthName()

        Try

            Dim dtinfo As DateTimeFormatInfo = DateTimeFormatInfo.GetInstance(Nothing)

            For i As Integer = 1 To 12

                Dim monthname As String = dtinfo.GetMonthName(i)

                ddlmonth.Items.Add(New ListItem(monthname, i.ToString()))

            Next

        Catch ex As Exception

        End Try

    End Sub

  

    Protected Sub ddlmonth_SelectedIndexChanged(sender As Object, e As System.EventArgs) Handles ddlmonth.SelectedIndexChanged

        Response.Write("<script>alert('Selected Month is : " & ddlmonth.SelectedItem.ToString() & "')</script>")

    End Sub
