After been working with the editor for several years i want to list my "wishlist"
Some features have been requested before, i try to link to those topics.

DocumentManager
  • Posibility to add "createdate" to the documentlist
  • use the RadFileExlorer as the "left side"

ImageManager

  • Posibility to add "createdate" to the documentlist
  • Use the RadFileExlorer as the "left side"
  • Image Preview (Display imagelist as either details or thumbspreview)
    Requested before here
  • Create linked thumbnail from Image Manager (insert an hyperlink to the big image with the thumb embedded in the hyperlink if there are both image and thumb, otherwise insert image)
    Requested before here
  • If using Custom Content Provider, Use binaryimage as imagepreview and imageurl.

Anyone that can inform me on coming features wil include this requests? If there are already examples with workaound with the current versions on AJAX or codelibrary?
I think many of this request are quite common...

Regards Pelle

Hello Pelle,

Thank you for the feedback. For the first issue - adding a new column to the editor file browser dialogs, this can be done with some custom code with the current (2009 Q3) version of the controls. See the following file explorer demo for more details - http://demos.telerik.com/aspnet-ajax/fileexplorer/examples/customgridcolumns/defaultcs.aspx. What you need to do is load the editor dialog FileBrowser.ascx from an external file and add a new server control in it. In the server control's code you can get a reference to the actual RadFileExplorer component, attach a handler to the ExplorerPopulated event, and use the code from the above example.

For the image preview option, we don't have a demo yet, but we still have plans to implement it in the future. The demo will probably use the new RadListView control instead of the RadGrid.

For the thumbnail linking to the original image, we will add an option in the next Service Pack release. The option will be in the image properties tab of the Image Manager dialog.

Finally, it is not possible to use the RadBinaryImage control in custom content providers, because when you insert the image in the editor content it becomes a normal HTML <img> tag and once it leaves the cache on the server, there is no .NET code to refresh it. The editor content is normal HTML, which is why you need to use a separate handler for custom providers and add additional parameters (e.g. the image virtual path). The URL to a RadBinaryImage control only has an ID parameter to lookup its image data in the cache. Once the data is gone (e.g. application is restarted or moved to another server), the ID parameter will point to nothing and the image will be gone.

Hi Lini, thanks for your reply!

>adding a new column to the editor file browser dialogs, this can be done with some custom code with the current (2009 Q3) version of the controls. See the following file explorer demo for more details
Great, that was what i wanted. Perhaps connected to an own provider.

>For the thumbnail linking to the original image, we will add an option in the next Service Pack release. The option will be in the image properties tab of the Image Manager dialog
This sound really great.... I understand the option will be in the propertiestab, but do you need to manual link the thumb, or can it be some automatic handling checking if an *_thumb.* exists and then create the linking?

>For the image preview option, we don't have a demo yet, but we still have plans to implement it in the future. The demo will probably use the new RadListView control instead of the RadGrid.
This sounds exactly what i long for, I even can take lot of time to help your development and create this by my self with some help from you if you are interested. Cause this is what i want to do myself so the time I take for this is not waisted at all. Please let me know if I can help you with this.

I understand the problem with RadBinaryImage, the reason i asked where if you combine an DB-driven provider and the images in the DB this would be an natural thought..

Regards Pelle

Hi Pelle,

The "link to original" option will only be visible if you have selected a file with the correct suffix (e.g. "_thumb") and a file without the suffix exists in the same folder. If a "_thumb" version does not exist the user will need to create one using the Image Editor option in the dialog.

About the thumbnail display using RadListView - it can be implemented relatively easy using the current RadFileExplorer version, but with limited features. For example - drag & drop functionality to/from the listview will not be available like in the RadGrid. The listview control will be updated when the selected node in the file explorer tree changes (client API). Then on the server the control will be databound and finally we can use the RadListView client selection features to raise the appropriate events in the file explorer when a user clicks/double clicks an item.

Best wishes,
Lini
