First off, 15 year desktop developer but total n00b web developer here. I'm trying to get a handle on the various SDK's for Web UI. We currently have an ASP.NET site to which I need to jump on and add a read-only property dialog. Below you will find a mockup of what I need to develop. The user doesn't need to interact with the modal dialog, but simply read and Close out.
What API would you recommend I use to mimic the look and feel of the below dialog? I'm getting lost in whether I should JQuery, core JavaScript, AJAX, ASP.NET controls or other. That is, I'm having trouble filtering in what I should be focusing on for SDK's and classes within those SDK's. I appreciate your help!
