[Solved] FileBrowserContentProvider Cannot write to the target folder

[Niclas Ahlqvist]

Hi!

I have some problems with my custom FileBrowserContentProvider.

I the Image editor I get an error message "Cannot write to the target folder".

I guess it has something to do with the path set in FileItem constructor and/or DirectoryItem constructor.

Ive set uploadpaths to "/" which I read in another forum thread.

Can you please explain how the paths set are used.

Hello Nicolas,

There may be a couple of reasons for this message:

• The CheckWritePermissions method of the content provider does not return the correct value, that applies to the logic of the implemented content provider. This method is called in order to determine whether a folder has write permission set.
• The application, in which the RadFileExplorer is used, does not have permissions to write to the folder. You can check this by using this code:
  

  protected void Page_Load(object sender, EventArgs e)
  {
      System.IO.Directory.CreateDirectory(@"C:\PathToDirectory");
      System.IO.File.Create(@"C:\PathToDirectory\PathToFile");
      System.IO.File.Delete(@"C:\PathToDirectory\PathToFile");
      System.IO.Directory.Delete(@"C:\PathToDirectory", true);
  }

  If this is the case, then an exception will be thrown in the Page_Load event. You can check the message of the exception in order to get the details report about the error.

I hope this helps.

Hi!

Thanks for the reply.

CheckWritePermissions always return true.

The asp.net devolopment server has permissions to write in the target dir.

I think this is a logical problem.

Since the files are stored in the database I dont have a physical filepath for them.

I wonder what path and location I should set in the FileItem and DirectoryItem contructor when neither exist on disc only in the database.

Hello Niclas,

Could you please check this online demo? It shows a custom FileBrowserContentProvider which connects the RadFileEditor control with a SQL database. A fully working project can be downloaded from this code library as well.

I hope this helps.
