Hi,
I'm using RadFileExplorer in a project that includes file version control. Occasionally, when attempting to save a new version of a file, I receive the alert:
"A file with a name same as the target already exists!"
This issue seems inconsistent — it doesn't appear limited to a specific file type, but I've noticed it more frequently with image files or files that have numbers in their names.
I came across a possible solution in this File Explorer as a Version Control issues. in UI for ASP.NET AJAX | Telerik Forums, where it was suggested to modify the GetFIle method to always return null. Here's the method :
{
string virtualPath = RemoveProtocolNameAndServerName(url);
string physicalPath = this.GetPhysicalFromVirtualPath(virtualPath);
if (physicalPath == null)
return null;
if (!File.Exists(physicalPath))
{
return null;
}
return File.OpenRead(physicalPath);
}
if it is okay to overriding this method to always return null? Is it a safe and recommended approach to prevent the "file already exists" error in version control scenarios?

I'm trying to add a alert inside the FileStore method in Telerik's File Explorer, but it's not working as expected. Here's my implementation:
public override string StoreFile(UploadedFile file, string path, string name, params string[] arguments)
{
string physicalPath = this.GetPhysicalFromVirtualPath(path);
if (physicalPath == null)
return string.Empty;
Directory.CreateDirectory(physicalPath);
// sanitize the file name
name = (name.Replace(" ", "_")).Replace("'", string.Empty);
physicalPath = PathHelper.AddEndingSlash(physicalPath, '\\') + name;
string fileName = Path.GetFileName(physicalPath);
string folderPath = Path.GetDirectoryName(physicalPath);
FileStorageManager fileStorageManager = new FileStorageManager();
FileStorageInformation fileInfo = fileStorageManager.GetFileByFolderAndFileName(_applicationID, folderPath, fileName);
string fileFolderRelativeToRoot = path;
string rootToThisContext = path;
string message = null;
if (File.Exists(physicalPath))
{
bool isVersioningDisabledOnDestination = false;
UploadingHandler uploadingHandler = new UploadingHandler();
uploadingHandler.ExecuteAction(fileInfo, fileName, fileFolderRelativeToRoot, rootToThisContext, _applicationID, _formID, _userID, ref isVersioningDisabledOnDestination);
if (isVersioningDisabledOnDestination)
{
message = string.Format("Can not upload - versioning not enabled on target folder");
}
}
if(message == null)
{
file.SaveAs(physicalPath);
return PathHelper.AddEndingSlash(path, '/') + name;
}
else
{
return message;
}
}
public override string StoreFile(UploadedFile file, string path, string name, params string[] arguments)
{
string physicalPath = this.GetPhysicalFromVirtualPath(path);
if (physicalPath == null)
return string.Empty;
Directory.CreateDirectory(physicalPath);
// sanitize the file name
name = (name.Replace(" ", "_")).Replace("'", string.Empty);
physicalPath = PathHelper.AddEndingSlash(physicalPath, '\\') + name;
string fileName = Path.GetFileName(physicalPath);
string folderPath = Path.GetDirectoryName(physicalPath);
FileStorageManager fileStorageManager = new FileStorageManager();
FileStorageInformation fileInfo = fileStorageManager.GetFileByFolderAndFileName(_applicationID, folderPath, fileName);
string fileFolderRelativeToRoot = path;
string rootToThisContext = path;
string message = null;
if (File.Exists(physicalPath))
{
bool isVersioningDisabledOnDestination = false;
UploadingHandler uploadingHandler = new UploadingHandler();
uploadingHandler.ExecuteAction(fileInfo, fileName, fileFolderRelativeToRoot, rootToThisContext, _applicationID, _formID, _userID, ref isVersioningDisabledOnDestination);
if (isVersioningDisabledOnDestination)
{

{
file.SaveAs(physicalPath);

}
else
{
return message;
}
}

I am getting error "You are trying to navigate to a non-existing folder or you do not have proper permissions to view this folder.
Please, contact the administrator." in my production environment. It is happening randomly.
Thanks.

I am able to drag and drop a message from old Outlook into Telerik File Explorer, but I can not do that in new Outlook. I am not sure if Telerik File Explore support that. And does Telerik File Explore support copy paste out look messages.

When I try to open a file I'd like to be able to click on a link to an Excel file and have it open directly in Excel on my computer, without any intermediate popup windows. Is this possible? or download to local?

With file explorer, I have no issues with creating a new folder with a string that contains a "&". The folder is created as expected.
But when I rename an existing folder to a string that contains a "&", the system will replace the "&" and "&". This behaviour is shown in the fileexplorer demo :

Is there a way to search for files in the directories when using the Document Manager/Image Manager. I see some code samples that allow for filtering in the selected folder, however that only filters one level and not sub directories. Looking for a way to search filenames through all sub folders.
