HttpCapabilitiesBase.RequiresHtmlAdaptiveErrorReporting Property

Gets a value indicating whether the browser requires nonstandard error messages.

Namespace:  System.Web.Configuration
Assembly:  System.Web (in System.Web.dll)

public virtual bool RequiresHtmlAdaptiveErrorReporting { get; }

Property Value

Type: System.Boolean
true if the browser requires nonstandard error messages; otherwise, false. The default is false.

If true, the browser does not properly render HTTP error messages. To correct this, server control adapters generate a custom error page for the browser.

The following code example shows how to determine whether the browser requires nonstandard error messages.

<%@ page language="C#"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<script runat="server">
    void Page_Load(Object Sender, EventArgs e)

    void CheckBrowserCaps()
        String labelText = "";
        System.Web.HttpBrowserCapabilities myBrowserCaps = Request.Browser;
        if (((System.Web.Configuration.HttpCapabilitiesBase)myBrowserCaps).RequiresHtmlAdaptiveErrorReporting)
            labelText = "Browser requires non-standard standard error messages.";
            labelText = "Browser does not require non-standard standard error messages.";

        Label1.Text = labelText;

<html xmlns="" >
    <title>Browser Capabilities Sample</title>
    <form runat="server" id="form1">
            Browser Capabilities:
            <p/><asp:Label ID="Label1" Runat="server" />
