string strExtension = System.IO.Path.GetExtension(FileNameTemp);  
 
 
 
FileNameTemp = FileNameTemp + 
 
"-" + Guid.NewGuid() + strExtension;  
 
fileName = fileName.Substring(0, fileName.LastIndexOf( 
 
"/") + 1) + FileNameTemp;

Hello Hossein,

1) You can implement a FileSystemContentProvider and override the StoreFile method. See this forum for more information: Reduce Image File Size

using System;  
using System.Collections;  
using System.Configuration;  
using System.Data;  
using System.Web;  
using System.Web.Security;  
using System.Web.UI;  
using System.Web.UI.HtmlControls;  
using System.Web.UI.WebControls;  
using System.Web.UI.WebControls.WebParts;  
using Telerik.Web.UI;  
using System.Drawing;  
using System.IO;  
   
   
public partial class static_test_editor : System.Web.UI.Page  
{  
    protected void Page_Load(object sender, EventArgs e)  
    {  
        RadEditor1.ImageManager.ViewPaths = new string[]{"~/"};  
        RadEditor1.ImageManager.UploadPaths = new string[] { "~/" };  
        RadEditor1.ImageManager.DeletePaths = new string[] { "~/" };  
        RadEditor1.ImageManager.ContentProviderTypeName = typeof(myprovider).AssemblyQualifiedName;  
    }  
   
    public class myprovider : Telerik.Web.UI.Widgets.FileSystemContentProvider  
    {  
   
        public myprovider(HttpContext context, string[] searchPatterns, string[] viewPaths, string[] uploadPaths, string[] deletePaths, string selectedUrl, string selectedItemTag)  
            : base(context, searchPatterns, viewPaths, uploadPaths, deletePaths, selectedUrl, selectedItemTag)  
        {  
        }  
   
        public bool ThumbnailCallback()  
        {  
            return false;  
        }  
   
        public override string StoreFile(UploadedFile file, string path, string name, params string[] arguments)  
        {  
   
            string result = base.StoreFile(file, path, name, arguments);  
   
            System.Drawing.Image.GetThumbnailImageAbort myCallback =  
                new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);  
   
            string fileName = Path.Combine(path, name);  
            //Create a copy of the image with a different size  
            using (System.Drawing.Image originalImage = Bitmap.FromStream(file.InputStream))  
            {  
                using (System.Drawing.Image thumbnail = originalImage.GetThumbnailImage(300, 300, myCallback, IntPtr.Zero))  
                {  
                    thumbnail.Save(Context.Server.MapPath(fileName));  
                }  
            }  
   
            return result;  
        }  
    }  
}   

2) You can use the InsertImage manager to insert images with web paths.

Hello there,

I am having a similar issue, I want to rename the uploaded files so non-latin characters are removed from its filename. I implemented my own FileSystemContentProvider, based in this post, and it works.

I am facing now 2 issues.

1. When the image manager refreshes after the file upload, the newly uploaded (and renamed) file is not selected.
2. The check if a file with the same name exists doesn't work, since I make a rename of the file.

Do you have any advice on how to resolve these issues?

Here is my implementation of the FileSystemContentProvider

* The Greek2GrEnglish function makes the character conversion of the file name.

Imports System
Imports System.Collections
Imports System.Configuration
Imports System.Data
Imports System.Web
Imports System.Web.Security
Imports System.Web.UI
Imports System.Web.UI.HtmlControls
Imports System.Web.UI.WebControls
Imports System.Web.UI.WebControls.WebParts
Imports Telerik.Web.UI
Imports System.IO

Public Class myProvider
    Inherits Telerik.Web.UI.Widgets.FileSystemContentProvider

    Public Sub New(context As HttpContext, searchPatterns As String(), viewPaths As String(), uploadPaths As String(), deletePaths As String(), selectedUrl As String, selectedItemTag As String)
        MyBase.New(context, searchPatterns, viewPaths, uploadPaths, deletePaths, selectedUrl, selectedItemTag)
    End Sub

    Public Overrides Function StoreFile(file As UploadedFile, path__1 As String, name As String, ParamArray arguments As String()) As String
        Dim new_result As String = MyBase.StoreFile(file, path__1, Greek2GrEnglish(name), arguments)

        Return new_result
    End Function
End Class

Hi Stathis,

The provided code snippet looks OK and I am not quite sure why do you experience the reported behavior.

Could you please verify that the result returned by StoreFile() method is the correct path to the file? Also, could you please open a formal support ticket and provide a sample fully runnable project reproducing the problem?

All the best,

Hello Dobromir,

I am really sorry for not replying in a timely manner, but I guess I missed the notification email for your reply.

The code I posted is correct, there was a bug outside this code.

Thank you
