DXFileDialog.DefaultExt Property

Gets or sets the default file name extension.

Namespace: DevExpress.Xpf.Dialogs

Assembly: DevExpress.Xpf.Dialogs.v21.2.dll


public string DefaultExt { get; set; }

Property Value

Type Description

The default file name extension. The returned string does not include the period. The default value is an empty string (“”).


When an end user specifies a file name without an extension, the DXFileDialog appends an extension to the file name. This extension is determined by the DXFileDialog.Filter and DefaultExt properties.

If a DXFileDialog.Filter is selected in the DXFileDialog and the filter specifies an extension, then that extension is used.

If the selected DXFileDialog.Filter uses a wildcard in place of the extension (e.g., "All files|*.*"), then the extension specified in the DefaultExt property is used.
