FileDialog::SupportMultiDottedExtensions Property

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

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
property bool SupportMultiDottedExtensions {
	bool get ();
	void set (bool value);
}

Property Value

Type: System::Boolean
true if the dialog box supports multiple file name extensions; otherwise, false. The default is 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 this property to true enables you to set the Filter property to a multi-dotted extension.

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

The following code example saves files with the extension ".data.txt". This code example requires that your application host a SaveFileDialog named saveFileDialog1 and a Button named button1.

No code example is currently available or this language may not be supported.
