The ASPxDateEdit control is available on the DX.19.1: Common Controls toolbox tab in the Microsoft Visual Studio IDE.

Drag the control onto a form and customize control settings, or paste the control markup in the page’s source code.

<dx:ASPxDateEdit ID="dateEdit" runat="server" EditFormat="Custom" Date="2009-11-02 09:23" 
Width="190" Caption="ASPxDateEdit">
        <TimeEditProperties EditFormatString="hh:mm tt" />
        <FastNavProperties DisplayMode="Inline" />

Run Time

using DevExpress.Web;
protected void Page_Load(object sender, EventArgs e)
    ASPxDateEdit dateEdit = new ASPxDateEdit();
    dateEdit.ID = "ASPxDateEdit1";

    dateEdit.EditFormat = EditFormat.Custom;
    dateEdit.Date = DateTime.Today;
    dateEdit.Caption = "Test date edit";
    dateEdit.CalendarProperties.FastNavProperties.DisplayMode = FastNavigationDisplayMode.Inline;
    dateEdit.TimeSectionProperties.Visible = true;
    dateEdit.TimeSectionProperties.TimeEditProperties.EditFormatString = "hh:mm tt";
    dateEdit.DisplayFormatString = "dd/MM/yyyy hh:mm tt";


Shared Drop-Down Calendar

Use the PopupCalendarOwnerID property to share a date editor’s popup calendar between several date editors. This allows you to decrease the rendered HTML size.

<dx:ASPxDateEdit ID="dtmDate1" runat="server" Date="2018-12-30" ...>

<dx:ASPxDateEdit ID="dtmDate2" runat="server" PopupCalendarOwnerID="dtmDate1">

<dx:ASPxDateEdit ID="dtmDate3" runat="server" PopupCalendarOwnerID="dtmDate1">

Null Prompt Text

The date editor displays a prompt text (NullText) when the editor’s value is null and the editor is not focused. The prompt text disappears when the editor receives focus.
