Web.Config Options

• Aug 21, 2021

A DevExpress section is automatically created within the Web.Config file when any DevExpress web control is added in Visual Studio from the Toolbox to the Design area. This section lists all available default DevExpress options, which allow you to control various features.

The following code demonstrates the default registration of this section in Web.Config:

XML

<configSections>
  <sectionGroup name="devExpress">
    <!--........-->
    <section name="bootstrap" type="DevExpress.Web.Bootstrap.BootstrapConfigurationSection, DevExpress.Web.Bootstrap.v18.2, Version=18.2.3.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a" requirePermission="false" />
  </sectionGroup>
</configSections>
<!--........-->
<devExpress>
  <bootstrap mode="Bootstrap4" iconSet="Embedded" />
  <resources>
    <add type="ThirdParty" />

  <settings accessibilityCompliant="true" doctypeMode="Html5" rightToLeft="false" checkReferencesToExternalScripts="true" protectControlState="true" ieCompatibilityVersion="edge" />
