AccessSettings Class

Allows you to restrict external resource locations for security reasons.

Namespace:DevExpress.Security.Resources
Assembly:DevExpress.Data.v19.1.dll

Expanded Syntax

Expanded Remarks

The following image illustrates how to use the AccessSettings class to allow or restrict certain resource locations:

The table below gives a brief overview of all the API and provides links for more information.

StaticResources (see StaticResources)

A static property that allows you to specify access settings for images.

DataResources (see DataResources)

A static property that allows you to specify access settings for data resources (JSON (see JsonDataSource) and Excel (see ExcelDataSource) data sources).

ReportingSpecificResources (see ReportingSpecificResources)

A static property that allows you to specify access settings for report style sheets and serialization formats.

SetRules

TrySetRules

Register resource access rules.

DirectoryAccessRule (see DirectoryAccessRule).Allow (see DirectoryAccessRule.Allow)

A static method that allows access to all or only specified directories.

DirectoryAccessRule (see DirectoryAccessRule).Deny() (see DirectoryAccessRule.Deny)

A static method that denies access to all or only specified directories.

UrlAccessRule (see UrlAccessRule).Allow() (see UrlAccessRule.Allow)

A static method that allows access to all or only specified URLs.

UrlAccessRule (see UrlAccessRule).Deny() (see UrlAccessRule.Deny)

A static method that denies access to all or only specified URLs.

You can also create a CustomAccessRule (see CustomAccessRule) to implement custom logic when a URI is checked.

You can call the SetRules method only once during a single application run. Subsequent calls raise an exception. This ensures that rules cannot be overridden once specified. Alternatively, use the TrySetRules method. It does not raise an exception, but returns false.

If no access rules are registered, resources can be loaded from any location.
