ImageManager Remove Spaces From Folder Names

[Dale Palmer]

Hi

Is it possible to remove spaces (replace them with underscores) from folder names when a user creates a new folder in the image upload dialog?

Thanks

Hi Dale,

You can also implement you own file system content provider and rename the uploaded files on the server. The following code demonstrates how to resize the images in the StoreFile function. You can use this method to rename the image files:

    protected void Page_Load(object sender, EventArgs e)
    {
        RadEditor1.ImageManager.ViewPaths = new string[]{"~/"};
        RadEditor1.ImageManager.UploadPaths = 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;
        }
    }

It's not the files that I need to rename its the folders that users can create in the ImageManager dialog.

See screenshot below

I want to remove any spaces in the name and replace them with underscores.

Hi Dale,

Thank you for the additional information. In this scenario you should override the CreateDirectory function and for example replace the space with _ underscore:

    protected void Page_Load(object sender, EventArgs e)
    {
        RadEditor1.ImageManager.ViewPaths = new string[]{"~/"};
        RadEditor1.ImageManager.UploadPaths = 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 override string  CreateDirectory(string path, string name)
        {
            name = name.Replace(" ","_");
            return base.CreateDirectory(path, name);
        }
    }

Thanks for your reply. That example works great except if I try to delete the new folder that i created then I keep getting a callback error. I have posted a screenshot of this error.

This pop occurs as soon as the new folder is deleted.

Callback Error
Image Manager Error

As you can see from the first screenshot I created a new folder called 'new 3 folder' and it correctly replaced the spaces with underscores but I'm presented with a new error.

Hi Dale,

You are using an older version of Telerik.Web.UI.dll. This problem is fixed in the latest Q2 2009 and my recommendation is to upgrade to it.

For your convenience I have attached my test project.

how can I add the class myprovider globally?  Or will I need to add it to each page that uses the editor?

Hello Marty,

Customized content providers cannot be used as a global configurations.

Although you can always create a custom user control, which inherits the RadEditor class and define additional configuration by overriding the OnLoad, OnRender or OnInit events. You can find attached an example for such approach.
