MaskProperties.UseMaskAsDisplayFormat Property

Gets or sets whether to use mask settings to format the editor’s display text when the editor is not focused.

Namespace: DevExpress.XtraEditors.Mask

Assembly: DevExpress.XtraEditors.v24.1.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

C#

[Browsable(false)]
[EditorBrowsable(EditorBrowsableState.Never)]
public virtual bool UseMaskAsDisplayFormat { get; set; }

VB.NET

<Browsable(False)>
<EditorBrowsable(EditorBrowsableState.Never)>
Public Overridable Property UseMaskAsDisplayFormat As Boolean

Property Value

Type	Default	Description
Boolean	false	true to use mask settings to format the editor’s display text when the editor is not focused; false to use formatting settings specified by the DisplayFormat property.

Remarks

Enable the UseMaskAsDisplayFormat property to apply mask settings to the editor’s display text (when the editor is not focused). As a result the editor’s text in edit and display mode will be identical.

The following example creates a DateTime editor to display/edit values in the ‘OrderDate’ grid column. The editor uses mask settings to format its value in edit and display modes:

C#

using System;
using System.Windows.Forms;
using DevExpress.XtraBars.Ribbon;
using DevExpress.XtraEditors.Repository;

namespace DXApplication {
    public partial class Form1 : RibbonForm {
        RepositoryItemDateEdit dateEditor;
        public Form1() {
            InitializeComponent();

            // Forcibly initialize the DevExpress GridControl.
            gridControl1.ForceInitialize();
            // Create and initialize a repository item (cell editor) to edit DateTime values.
            dateEditor = new RepositoryItemDateEdit() {
                Name = "orderDateEditor",
                EditMask = "D",
                UseMaskAsDisplayFormat = true
            };
            // Add the repository item to the grid's RepositoryItems collection.
            gridControl1.RepositoryItems.Add(dateEditor);
            // Assign the repository item to the 'OrderDate' column.
            gridView1.Columns["OrderDate"].ColumnEdit = dateEditor;
        }
    }
}

VB.NET

Imports System
Imports System.Windows.Forms
Imports DevExpress.XtraBars.Ribbon
Imports DevExpress.XtraEditors.Repository

Namespace DXApplication
    Partial Public Class Form1
        Inherits RibbonForm

        Private dateEditor As RepositoryItemDateEdit
        Public Sub New()
            InitializeComponent()

            ' Forcibly initialize the DevExpress GridControl.
            gridControl1.ForceInitialize()
            ' Create and initialize a repository item (cell editor) to edit DateTime values.
            dateEditor = New RepositoryItemDateEdit() With {
                .Name = "orderDateEditor",
                .EditMask = "D",
                .UseMaskAsDisplayFormat = True
            }
            ' Add the repository item to the grid's RepositoryItems collection.
            gridControl1.RepositoryItems.Add(dateEditor)
            ' Assign the repository item to the 'OrderDate' column.
            gridView1.Columns("OrderDate").ColumnEdit = dateEditor
        End Sub
    End Class
End Namespace

The following image shows the result:

If the UseMaskAsDisplayFormat property is set to false, the editor’s display text is formatted based on settings specified by the DisplayFormat property.

Note

Setting the UseMaskAsDisplayFormat property has no effect if the editor’s MaskProperties.MaskType property is set to MaskType.None.
