ASPxHtmlEditor - Provide a way to use a custom FileSystemProvider in dialogs

created 9 years ago

Hello,
we have written our own FileSystemProvider, which we use with FileManager in custom SelectImageForm.ascx. After upgrade DevExpress ASP.NET controls to version 15.1.5 is no longer supported custom dialogs and is recommended using InsertImageDialog which is directly part HTMLEditor components.
My question is, if there's any way to substitute our FileSystemProvider to HTMLEditor, or if you have any demo project how to proceed in this case?

We upgrade from 14.1. version.

Thak you for answer.

    Hello,

    Starting with v15.1, the default ASPxHtmlEditor dialogs are rendered at runtime. Thus, the previous approach for customization with User Controls is not efficient any more. We provide a way for changing the default rendering using the SettingsDialogssettings. However, these settings are more  suitable for appearance customization rather than changing the logic of the default dialogs.

    The most efficient solution is to implement a custom dialog replicating the "Insert Image" dialog behavior. I recommend that you refer to the T263833: ASPxHtmlEditor - Custom default dialogs after 14.2? ticket, where such a dialog is implemented. You can use it as a base for your scenario.
