Overwrite on file drag

[Koren]

Is there any way to allow an overwrite when someone drags a file to a folder that already has a file with that name?  I know it works on the Upload functionality but I need it to allow it for a drag and drop also.

thanks!

Hi Koren,

You can achieve the required functionality by implementing a custom filebrowser content provider to RadFileExplorer and override the CopyFile() method to delete the file in the destination folder (if already exists) and then perform the copy, e.g.:

public override string CopyFile(string path, string newPath)
{
    string oldPhysicalPath = MapPath(path);
    string newPhysicalPath = MapPath(newPath);
    if(File.Exists(newPhysicalPath)
    {
        try
        {
            File.Delete(newPhysicalPath);
        }
        catch(UnauthorizedAccessException)
        {
            return "NoPermissionsToDeleteFile";
        }
    }

    return base.CopyFile(path, newPath);
}

All the best,

Thank you!  The only change I had to make was to add a MoveFile override also.
