Image Manager

[Anooshiravan]

     When trying to add some images using RADEDITOR there is some error that says:

"Cannot deserialize dialog parameters. Please refresh the editor page.
Error Message:Invalid character in a Base-64 string."

so I can only enter text.

Dialog parameters serialization are canged due to some security issue in last release of  Telerik UI for ASP.NET AJAX.
for now, those parameters are using a randomly generated key each time the application restarts.


you can add a tweak to keep the key static

use this code:

<

<appSettings>
    <add key="Telerik.Web.UI.DialogParametersEncryptionKey" value="YOUR-STRONG-RANDOM-VALUE-UNIQUE-TO-YOUR-APP&" />
</appSettings>

 

Thanks

Hi Anooshiravan,

Along with the suggested by Himanshu key, I would also advise that you add all mandatory settings listed in the following article:
