DXFileDialog.SupportMultiDottedExtensions Property

Gets or sets whether the file dialog supports displaying and saving files that have multiple file name extensions.

Namespace: DevExpress.Xpf.Dialogs

Assembly: DevExpress.Xpf.Dialogs.v23.1.dll

NuGet Package: DevExpress.Wpf.Dialogs


public bool SupportMultiDottedExtensions { get; set; }

Property Value

Type Default Description
Boolean false

true, if the file dialog supports multiple file name extensions; otherwise, false.


Sometimes users must open and save files that use multiple file name extensions. For example, the application manifest files used by the ClickOnce deployment technology end in the complex file name extension “.exe.manifest“. Setting the SupportMultiDottedExtensions property to true enables you to set the DXFileDialog.Filter property to a multi-dotted extension.

If SupportMultiDottedExtensions is false, and you assign a multi-dotted extension to DXFileDialog.Filter, derived controls such as DXSaveFileDialog will only use the last extension in the string. For example, “.manifest“ will be used instead of “.exe.manifest“.
