DateEdit Main Features

The DateEdit extension is a date editor that combines the functionalities of a single-line text editor, button editor and dropdown calendar. The editor's dropdown displays a calendar that allows end-users to select dates, and navigate through months and years.

The DateEdit offers the following features.

  • Shared Drop-Down Calendar

    Using the DateEditSettings.PopupCalendarOwnerName property, an individual date editor's popup calendar (and its settings) can be shared between several date editors, which decreases the size of the HTML code rendered into the web page by date editors.

  • Null Prompt Text

    The prompt text can be displayed if the editor's value is null and the editor is not focused. The prompt text disappears when the editor receives focus. You can define the prompt text via the DateEditSettings.Properties.NullText (DateEditProperties.NullText) property.

  • Edit Formatting

    You can specify how an editor value is represented within the edit boxes. For display and edit purposes, the edited value can be displayed in the following formats.

    View Affected Properties
    EditFormat= "Date"


    EditFormatString:="MMMM dd, yyyy hh:mm tt"

  • Display Formatting

    The editor display value can be formatted for display purposes when the editor is not focused via the DateEditSettings.Properties.DisplayFormatString (DateEditProperties.DisplayFormatString) property.

  • Masked Input

    If the DateEditSettings.Properties.UseMaskBehavior (DateEditProperties.UseMaskBehavior) property is set to true, the DateEdit editor supports masked input. In this mode, the pattern defined via the DateEditSettings.Properties.EditFormatString (DateEditProperties.EditFormatString) property serves as a mask.

  • Easy Date Selection

    The DateEdit allows end-users to edit a date value by selecting it within a drop-down calendar, or by typing a date directly into the editor's text box, or by using the mouse wheel or keyboard.

  • Customizable Button Collection

    The DateEdit extension provides a collection to maintain its custom edit buttons. Each button exposes a set of properties allowing the button's appearance and behavior to be defined. The settings of the default button, which invokes the dropdown calendar when clicked, can be customized as well.

  • Built-in Validation

    The DateEdit extension allows you to perform data validation both on the client and server side. See the Built-in Validation topic to learn more.

  • Full-Featured Client-Side API

    DateEdit provides you with a comprehensive client-side API. This API is implemented using JavaScript and is exposed via the ASPxClientDateEdit object. The ASPxClientDateEdit object serves as a client-side equivalent of the DateEdit extension.

    You can modify editor behavior using the following methods.

    Method Description
    ASPxClientDateEdit.GetCalendar Returns the calendar of the date editor.
    ASPxClientDateEdit.GetDate Gets the date that is the editor's value.
    ASPxClientDateEdit.GetMaxDate Gets the maximum date of the editor.
    ASPxClientDateEdit.GetMinDate Gets the minimum date of the editor.
    ASPxClientDateEdit.SetMaxDate Sets the maximum date of the editor.
    ASPxClientDateEdit.SetMinDate Sets the minimum date of the editor.
