RadEditor ImageManager Fails to Connect to ViewPath

We sporadically have a problem when using the RadEditor where a user clicks on the ImageManager button, and when the image manager opens the entire window is greyed out and there is no path information displayed, rendering the window unusable. Attempts to close and re-open the image manager usually result in the same result at this point (presumably because something is being cached?). Our setup isn't very complicated, Each of our clients has their own unique folder that they upload images / documents / templates into, and we specify this in the code behind like this:

EMailContentEditor.ImageManager.UploadPaths = new[] { string.Format("/ImageLibrary/account{0}/images", p_AccountId) };
EMailContentEditor.ImageManager.DeletePaths = new[] { string.Format("/ImageLibrary/account{0}/images", p_AccountId) };
EMailContentEditor.ImageManager.ViewPaths = new[] { string.Format("/ImageLibrary/account{0}/images", p_AccountId) };

We do run multiple web servers and /ImageLibrary is virtual directory in IIS that points to a shared NAS.

What i'm trying to find out is how i can find out more information about why these sporadic connection attempts are failing. I've also contacted my data center to see if there are any kind of connection logs associated with our NAS that could show the error. But i'd like to know is there an exception that is thrown or could be trapped when this error happens, or any way that i could force the RadEditor to retry the connection when it doesn't connect the first time? We've been using this solution for a number of years now and it's always worked fine. Lately i seem to be hearing more and more complaints about it, however in the grand scheme of things we're probably only talking a fraction of a %.

Any help or ideas you can provide are most appreciated. We are using version 2012.2.619.40 in production and will be upgrading to 2012.2.815.40 in the next 2 weeks.

Regards,
-Mark

Change Month in Scheduler

Hi there,

nice controls! Actually bought 2 licenses a few days ago for my company ...

Here is my question:

How can I change the month (or week, day) of the scheduler based on an external event (like onclick() in ListBox1) - in JAVASCRIPT? No postback and/or web service, please!

Can this be done?
Yes => How?
No => Can you refer me to an example with server side code?
Thanks a million times!

GridAttachmentColumn Validation

Hi,

I'm following the GridAttachmentColumn demo and saving to the database - all works well, but in the demo, if no file is uploaded the error message is added like so:-

RadGrid1.Controls.Add(New LiteralControl("<b style='color:red;'>No file uploaded. Action canceled.</b>"))

This puts the message right at the bottom of the grid - is there a way to show it within the auto generated edit form please?

Also, I did look but is there an example of the GridAttachmentColumn using an edit form template?

Cheers,

Jon
