Specifies the path where the exported document is sent for saving.

Namespace: DevExpress.AspNetCore.RichEdit

Assembly: DevExpress.AspNetCore.RichEdit.v19.2.dll

Declaration

public RichEditBuilder ExportUrl(
    string url
)

Parameters

Name	Type	Description
url	String	The URL.

Returns

Type	Description
RichEditBuilder	An object that can be used to further configure the Rich Text Editor.

Remarks

Set the ExportUrl property to process document saving on the server side.

The ExportUrl property is not in effect if the document saving is implemented on the client side (the handled property is set to true).

View

@(Html.DevExpress().RichEdit("richEdit")
   .ExportUrl(Url.Action("Export"))
   .Height(600)
   .ConfirmOnLosingChanges(c => c.Enabled(false))
)

Controller

public IActionResult Export(string base64, string fileName, DevExpress.AspNetCore.RichEdit.DocumentFormat format, string reason) {
    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.

C#

public IActionResult Export([FromForm]string base64, [FromForm]string fileName, [FromForm]int format, [FromForm]string reason) {  
  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.

Disable the AntiForgeryToken option (enabled for Razor Pages web apps by default).

• To disable the AntiForgeryToken for an application, add the following code to the ConfigureServices method in Startup.cs.

  services.AddMvc().AddRazorPagesOptions(o =>
  {
      o.Conventions.ConfigureFilter(new IgnoreAntiforgeryTokenAttribute());
  });
  

• To disable the AntiForgeryToken for a page, add the following code to a page model.

  [IgnoreAntiforgeryToken]
  public class IndexModel : PageModel
  {
      public void OnPost()
      {
      }
  }    
  

Declare a POST action handler to save a document.

C#

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

Use this handler in the ExportUrl method as follows.

C#

    .ExportUrl("RichEditPage?handler=export")
