...another way to get advantage of the power of Silverlight within Crm 2011 is to use the whole entity form real estate. We can do this by adding a navigation item to an existing group. The navigation area is divided into five areas: Common, Sales, Service, Marketing and for entities that support them, Processes, We can either use the form editor using drag and drop to change their vertical position, add new items, move existing items to another area or use the "FormXml" element (I will talk about how to customise the FormXml element in another post) to achieve the same result.
N.B. "In Microsoft Dynamics CRM 2011 , the ability to add navigation items to the entity form has been moved from ISV.Config to the <FormXml> (FormXML) element for each entity form. During upgrade from Microsoft Dynamics CRM 4.0, any entity form navigation customizations in the ISV.Config are moved to the definition of the main form for that entity."
So, let's see how we can customise an entity navigation form; first of all we are going to add a new navigation item to an existing area (it is not possible to add a new area). Open an entity record select the Customize tab and click on "Form",
this will open the form editor, at this point click on "Navigation" select the area on the navigation menu that you want to customise,
select the "Insert" tab,
and click the Navigation Link button,
Select a name, look up for an icon and the HTML web resource that hosts your Silverlight application that you have previously added.
And here is the final result.
Hope you enjoyed. :)
