How to populate dropdownlist with months name in Asp.net

Description:-

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

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.

HTML:-

<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

using System.Globalization;

Get month’s name:-

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

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>");
}
