How to: Set Today's Date Programmatically in a Calendar Web Server Control

  • Article

By default, the value of "today" in the Calendar control is set to match the date of the server on which the Web Forms page runs. However, you might need to adjust the date to accommodate users who are viewing the page from a different time zone.

To set today's date programmatically

  • Set the Calendar control's TodaysDate property to a DateTime value.

    The following example sets TodaysDate to tomorrow and then sets the SelectedDate to TodaysDate. In the browser, the date for tomorrow will be highlighted.

    Dim tomorrow As Date = Date.Today.AddDays(1)
Calendar1.TodaysDate = tomorrow
Calendar1.SelectedDate = Calendar1.TodaysDate

    DateTime tomorrow = DateTime.Today.AddDays(1);
Calendar1.TodaysDate = tomorrow;
Calendar1.SelectedDate = Calendar1.TodaysDate;

    The following example shows how you can fill a DropDownList control with a selection of dates and then set the value of today's date in the Calendar control according to the user's selection from the list.

    Protected Sub Page_Load(ByVal sender As Object, _
        ByVal e As System.EventArgs) Handles Me.Load
    If Not IsPostBack Then
        Dim today As DateTime = System.DateTime.Today
        Dim yesterday As DateTime = today.AddDays(-1)
        Dim tomorrow As DateTime = today.AddDays(1)
        DropDownList1.items.Add(String.Format("{0:dd MMM yyyy}", _
           today))
        DropDownList1.items.Add(String.Format("{0:dd MMM yyyy}", _
           yesterday))
        DropDownList1.items.Add(String.Format("{0:dd MMM yyyy}", _
           tomorrow))
    End If
End Sub

Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender _
        As Object, ByVal e As System.EventArgs) _
        Handles DropDownList1.SelectedIndexChanged
    Calendar1.TodaysDate = _
        Date.Parse(DropDownList1.SelectedItem.Text)
End Sub

    protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        DateTime today = System.DateTime.Today;
        DateTime yesterday = today.AddDays(-1);
        DateTime tomorrow = today.AddDays(1);
        DropDownList1.Items.Add(String.Format("{0:dd MMM yyyy}",
           today));
        DropDownList1.Items.Add(String.Format("{0:dd MMM yyyy}",
           yesterday));
        DropDownList1.Items.Add(String.Format("{0:dd MMM yyyy}",
           tomorrow));
    }
}
protected void DropDownList1_SelectedIndexChanged(object sender, 
    EventArgs e)
{
    Calendar1.TodaysDate = 
        DateTime.Parse(DropDownList1.SelectedItem.Text);
}
