View

cshtml

@(Html.DevExpress().RichEdit("richEdit")
   .Pdf(p => {
       p.ExportUrl(Url.Action("Export"));
   })
   .Fonts(f =>
   //...
)

Controller

csharp

public IActionResult Export(string base64, string fileName) {
    byte[] fileContents = System.Convert.FromBase64String(base64);
    return Ok();
}

Note

If you apply the [ApiController] attribute to your controller, you should add the [FromForm] attribute to parameters in the Export action.

csharp

public IActionResult Export([FromForm]string base64, [FromForm]string fileName) {
   byte[] fileContents = System.Convert.FromBase64String(base64);
   return Ok();
}

For Razor Pages web apps only

To use the ExportUrl method in a Razor Pages web app, it is necessary to add the following adjustments.

Add an anti‑forgery token to internal requests the Rich Text Editor sends to action handlers. This token prevents Cross-Site Request Forgery (CSRF/XSRF) attacks.

razor

@inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Antiforgery

<script>
    function richEdit_beforeSend(richEdit, e) {
        e.request.setRequestHeader("RequestVerificationToken",
                                "@Antiforgery.GetAndStoreTokens(HttpContext).RequestToken");
    }
</script>

@(Html.DevExpress().RichEdit("richEdit")
    .ExportUrl(Url.Page(pageName: null, pageHandler: "Export"))
    .OnBeforeSend("richEdit_beforeSend")
)

Declare a POST action handler to save a document.

csharp

public void OnPostExport(string base64, string fileName) {
    byte[] fileContents = System.Convert.FromBase64String(base64);
 }

Use this handler in the ExportUrl method as follows.

csharp

.ExportUrl("RichEditPage?handler=export")
