.NET Image Manager

How it works

  1. Specify image load options when the editor is initialized on the client side.
  2. When the Image Manger modal displays, the editor makes a request to the server to load the images.
  3. Once the request reaches the server, it returns a list with the images to display in the editor.
  4. The editor processes the server response and renders the images in its interface.

Jump to Complete Example

initialize the editor

First, set the imageManagerLoadURL and imageManagerDeleteURL options, this allows the editor to interact with the server to load and delete images listed on the Image Manager.

Next, you can set other options related to the interaction between the server and the editor: imageManagerLoadMethod, imageManagerLoadParams, imageManagerPreloader, imageManagerDeleteParams.

<script>
  new FroalaEditor('.selector', {
    // Set the image upload URL.
    imageManagerLoadURL: '/FroalaApi/LoadImages',

    // Set the image delete URL.
    imageManagerDeleteURL: '/FroalaApi/DeleteImage'
  })
</script>

Receive the load request

The server implementation is responsible for receiving the request and handling it appropriately. The editor's .NET SDK can load all the images inside a specified folder using the FroalaEditor.Image.List method.

Note: The path of the folder from where the images are loaded is relative to the root of the project.

string uploadPath = "/Public/";
object response = FroalaEditor.Image.List(System.Web.HttpContext.Current, uploadPath);

Receive the delete request

The server should listen for any delete request and process it accordingly. The initialization step makes the image path available in the HttpContext global variable. The FroalaEditor.Image.Delete method from the .NET SDK expects the path of the image to remove from disk.

FroalaEditor.File.Delete("/Public/" + HttpContext.Request.Form["src"]);

Complete Example

<script>
  new FroalaEditor('.selector', {
    // Set the image upload URL.
    imageManagerLoadURL: '/FroalaApi/LoadImages',

    // Set the image delete URL.
    imageManagerDeleteURL: '/FroalaApi/DeleteImage'
  })
</script>
using System;
using System.Web.Mvc;

namespace demo.Controllers
{
    public class FroalaApiController : Controller
    {
        public ActionResult LoadImages()
        {
            string uploadPath = "/Public/";

            try
            {
                return Json(FroalaEditor.Image.List(System.Web.HttpContext.Current, uploadPath));
            }
            catch (Exception e)
            {
                return Json(e);
            }
        }

        public ActionResult DeleteImage()
        {
            try
            {
                FroalaEditor.Image.Delete("/Public/" + HttpContext.Request.Form["src"]);
            }
            catch (Exception e)
            {
                return Json(e);
            }


            return Json(true);
        }
    }
}
