    <p>I would like to know how to call a POCO class (static) C# utility method from AJAX (or jquery or javascript or whatever) from an MVC view. I want to call this utility method from a number of different views based on client-side user inputs (e.g., clicking the jquery fullcalendar eventClick) without having to integrate the utility with each view's controller. The ultimate goal is to render a colorbox modal dialog, or at least send the JQuery colorbox parameters/syntax back to the view to be executed in the view (client-side). The purpose of the server-side method is to standardize calls to jquery colorbox dialogs. I understand in principle that MVC controllers aren't tied to being used from particular views. So, how would I set up the controller with action methods for common utilities and how would I set up the call to the controller from the view? The view call will pass two string parameters (based on which event the user clicks) to the server-side utility method: key, identifier. The server-side method will do a lookup based on the key and pass back a string value containing the colorbox call that the JQuery function in the view will execute (or it could also be an object containing name/value pairs for the colorbox call parameters).</p> <p>Below is an example of the server-side utility class code (without supporting methods, etc.). Thanks in advance.</p> <pre><code>namespace UI.Utility.Details { public static class Details { [WebMethod] public static string CallColorbox(string key, string identifier, string colorboxCall) { if (string.IsNullOrEmpty(key)) throw new Exception("Error: No key supplied."); if (string.IsNullOrEmpty(identifier)) throw new Exception("Error: No identifier supplied."); DetailSettings settings = GetSettings(key, identifier); if (settings == null) throw new Exception(string.Format("Error: Settings not found for key [{0}].", key)); colorboxCall = null; if (settings != null) { //$.colorbox({iframe:true, innerWidth:500, innerHeight:350, href:newUrl, opacity:0.35, scrolling:false }); colorboxCall = string.Format( //"$.colorbox({ iframe:{0}, innerWidth:{1}, innerHeight:{2}, {3}:{4}, opacity:{5}, scrolling:{6} });", "{0} iframe:{1}, innerWidth:{2}, innerHeight:{3}, {4}:{5}, opacity:{6}, scrolling:{7} {8}", "{", settings.iframe, settings.innerWidth, settings.innerHeight, settings.identifierType, settings.identifier, settings.opacity, settings.scrolling, "}" ); } if (string.IsNullOrEmpty(colorboxCall)) throw new Exception(string.Format("Error: colorbox call not constructed for key [{0}].", key)); return colorboxCall; } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
