ASPxRichEditUrlValidationContext Class

Identifies the context of a hyperlink URL validation request in the ASPxRichEdit control.

Namespace : DevExpress.Web.ASPxRichEdit

Assembly : DevExpress.Web.ASPxRichEdit.v25.2.dll

NuGet Package : DevExpress.Web.Office

Declaration

C#
VB.NET

csharp

public sealed class ASPxRichEditUrlValidationContext :
    UriValidationContext

Public NotInheritable Class ASPxRichEditUrlValidationContext
    Inherits UriValidationContext

Remarks

The Rich Text Editor component validates hyperlink URL schemes to prevent malicious code execution.

To override URL validation behavior, handle the UriValidated event. Event arguments include an instance of ASPxRichEditUrlValidationContext that identifies the ASPxRichEdit control that initiated the URL validation.

The following code snippet allows FTP links in a specific DevExpress.Web.ASPxRichEdit control:

csharp

using System;
using DevExpress.Security.Resources;
using DevExpress.Web.ASPxRichEdit;

protected void Application_Start(object sender, EventArgs e) {
    AccessSettings.UriValidated += OnUriValidated;
}

void OnUriValidated(object sender, UriValidatedEventArgs e) {
    // Checks if validation request comes from ASPxRichEdit
    if (e.ValidationContext is ASPxRichEditUrlValidationContext richEditContext) {
        var editor = richEditContext.Editor;
        // Allows custom URI scheme for specific editor instances
        if (editor.ID == "MyRichEdit" && e.Uri != null) {
            if (e.Uri.Scheme.Equals("ftp", StringComparison.OrdinalIgnoreCase)) {
                // Overrides validation to allow FTP links
                e.Valid = true;
            }
        }
    }
}
