Web.Config Options

  • 2 minutes to read

A DevExpress section is automatically created within the Web.Config file when you add a DevExpress MVC extension to a page using the Insert DevExpress MVC Extension Wizard or create an application via the Template Gallery. This section lists all available default DevExpress options that control various features.

The default registration of this section in Web.Config is as follows. 

<configuration>
  <configSections>
    <sectionGroup name="devExpress">
      <section name="themes" type="DevExpress.Web.ThemesConfigurationSection, DevExpress.Web.v24.2, Version=24.2.3.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a" requirePermission="false" />
      <section name="compression" type="DevExpress.Web.CompressionConfigurationSection, DevExpress.Web.v24.2, Version=24.2.3.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a" requirePermission="false" />
      <section name="settings" type="DevExpress.Web.SettingsConfigurationSection, DevExpress.Web.v24.2, Version=24.2.3.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a" requirePermission="false" />
      <section name="errors" type="DevExpress.Web.ErrorsConfigurationSection, DevExpress.Web.v24.2, Version=24.2.3.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a" requirePermission="false" />
      <section name="resources" type="DevExpress.Web.ResourcesConfigurationSection, DevExpress.Web.v24.2, Version=24.2.3.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a" requirePermission="false" />
    </sectionGroup>
  </configSections>
  ...
  <devExpress>
    <themes enableThemesAssembly="true" styleSheetTheme="" theme="Metropolis" customThemeAssemblies="" baseColor="Green" font="30px 'Callibri'"  />
    <compression enableHtmlCompression="false" enableCallbackCompression="true" enableResourceCompression="true" enableResourceMerging="true" />
    <settings doctypeMode="Html5" rightToLeft="false" ieCompatibilityVersion="edge" />
    <errors callbackErrorRedirectUrl="" />
    <resources>
      <add type="ThirdParty" />
      <add type="DevExtreme" />
    </resources>
  </devExpress>
</configuration>

The following DevExpress options are available within a web project’s Web.Config file.

Note

If IIS compression is configured on the server, disable DevExpress Web.config options related to compression (Page Html Compression, Callback Compression, Resource Compression and Resource Merging options) to avoid behavior issues.
