Sample: SDK.ControlSamples.js

[Applies to: Microsoft Dynamics CRM 2011]

This sample code is for Microsoft Dynamics CRM 2011, and can be found in the following location in the SDK download: SDK\SampleCode\JS\FormScripts\SDK.ControlSamples.js

Requirements

This sample code represents a JScript library that can be added as a Web resource. Before a function in a JScript library can be used as a form event handler, the JScript library must be added to the form libraries available for that form. The full name of the function must be used in the form event handler. For example, the showControlParents function must be called using SDK.ControlSamples.showControlParents.

Example


//If the SDK namespace object is not defined, create it.
if (typeof (SDK) == "undefined")
{ SDK = {}; }
// Create Namespace container for functions in this library;
SDK.ControlSamples = {};

 // control.addCustomView() example
 // control.getDefaultView() example
 // control.setDefaultView() example
 // control.getName() example
 // Example: The addCustomView function will add a new custom lookup called “SDK Sample View” to any lookup on the form that has a 
 // default view that shows account records.

SDK.ControlSamples.addCustomView = function () {
 // Most of the code in this example is simply to look for any account lookups in a given form.
 // Actually setting the custom view is done in the SDK.ControlSamples.setCustomViewOnAccountLookup function below.
