The TemplateResult property returns the result of the last instruction into a Template call, as a NAVObjectTemplate object. Use the Template/Item property to get/set properties / fields / parameters, invoke methods of the hosting /NET framework Value, using the x-script code. The Item property does exactly the same thing as Template call, excepts that it returns the TemplateResult property. For instance, using the Template/Item property you can change the hosting control's background color, add nodes, and so on. The TemplateThrowError property specifies whether the control fires an exception/error when the Template call fails. The TemplateError / TemplateException gets the error if the Template calls fails.
