A date editor control.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.1.dll

NuGet Package: DevExpress.Web


public class ASPxDateEdit :


The ASPxDateEdit is a drop-down editor that provides the drop-down calendar and time editor.

DateEdit Control

The calendar allows end users to select dates and navigate through months and years. The ASPxDateEdit.Date property specifies the currently selected date. Change this property to raise the ASPxDateEdit.DateChanged event.

The editor’s dropdown window contains two sections:

Create a Date Edit

Design Time

The ASPxDateEdit control is available on the DX.23.1: Common Controls toolbox tab in the Microsoft Visual Studio IDE.

DateEdit Control

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


To properly function, DevExpress controls require that special modules, handlers and options are registered in the the Web.config file. Switch the Microsoft Visual Studio IDE to the Design tab to automatically update the Web.config file with the required DevExpress information.

<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.

<dx:ASPxDateEdit ID="DateEdit" runat="server" NullText="mm/dd/yyyy" >

See demo

Edit Format

The EditFormat property allows you to specify how the editor displays its value in the edit box.

The ASPxDateEditor provides the following formats:


Affected Properties




EditFormat= “Date”





EditFormatString:="MMMM dd, yyyy hh:mm tt"
<dx:ASPxDateEdit ID="dateEdit" runat="server" EditFormat="Custom" Date="2009-11-02 09:23" >

See demo

Display Format

Use the DisplayFormatString property to specify a format pattern used to display the editor value when the control is in browse mode.

<dx:ASPxDateEdit ID="dateEdit" runat="server" DisplayFormatString="dd/MM/yyyy hh:mm tt" >

See demo

Masked Input

The ASPxDateEditor supports masked input (UseMaskBehavior). In this mode, the editor uses the EditFormatString property value as a mask.

<dx:ASPxDateEdit ID="dateEdit" runat="server" UseMaskBehavior="true" EditFormatString="MMMM dd, yyyy" >

Minimum and Maximum Dates Customization

You can define the earliest and the latest date an end-user can select in the drop-down calendar (MinDate and MaxDate).

<dx:ASPxDateEdit ID="dateEdit" runat="server" MinDate="2009-11-01" MaxDate="2009-11-20" >

Set the ShowOutOfRangeWarning property to true to display a warning message when an end-user types a date that is out of the specified date range.

DateEdit - ShowOutOfRangeWarning


The ASPxDateEdit control allows you to validate its value on the client and server side.

Date Range Picker

You can combine two ASPxDateEdit controls to implement a date range picker functionality. The first date editor specifies the range’s start date, the second - the range’s end date. Assign the start-date editor’s ID to the end-date editor’s StartDateEditID property to link editors.

<dx:ASPxDateEdit ID="deStart" ClientInstanceName="deStart" runat="server">

<dx:ASPxDateEdit ID="deEnd" ClientInstanceName="deEnd" runat="server">
    <DateRangeSettings StartDateEditID="deStart"></DateRangeSettings>

DateEdit - StartDateEditID

Month-Year Picker Mode

The Month-year Picker mode allows you to specify a date component an end user can select: a day, a month or a year. You can click the header to change the calendar view (fast navigation). Use the following settings to specify the date selection and restrict the available calendar views:




Specifies a date component an end user can select (a day, month or year).


Specifies the initial calendar view.


Specifies the earliest available calendar view. For example, if the CalendarFastNavProperties.MaxView property is set to “Months”, the picker displays the months of a particular year and January is the earliest available Calendar view item.

<dx:ASPxDateEdit runat="server" ID="dateEdit2" PickerType="Months">
        <FastNavProperties InitialView="Years" MaxView="Years" />

See demo

Button Collection

The ASPxDateEdit control allows you to create custom buttons. The editor stores its default and custom buttons in the ASPxButtonEditBase.Buttons collection. A custom button is an EditButton instance. Use the ASPxButtonEditBase.ButtonClick event to handle a button click.

<dx:ASPxDateEdit ID="txt_dueDate" runat="server" ...>
        <dx:EditButton Enabled="true" Text="TestButton">
        ButtonClick="function (s,e) {
          if(e.buttonIndex == 0)
              // your code
    }" />
