IE Compatibility Version

This option specifies how all DevExpress controls are rendered and forces the Internet Explorer browser to use the specified Document Mode to achieve consistent behavior, regardless of whether the browser’s Compatibility Mode is enabled or not.


        <settings ieCompatibilityVersion="edge" />


In order to use the DevExpress Web.config section, register this section group beforehand.

This configuration key accepts the following values:

  • An integer value that specifies the target Internet Explorer browser compatibility version;
  • The “edge“ string value (i.e., the maximum available version);
  • An empty string value (disables all compatibility adjustments).

This option is set to “edge” by default.
