Remarks
If a template whose name matches the templateName parameter is found in the controller's EditorTemplates folder, that template is used to render the expression. If a template is not found in the controller's EditorTemplates folder, the Views\Shared\EditorTemplates folder is searched for a template that matches the name of the templateName parameter. If no template is found, the default template is used.
This method generates different HTML markup depending on the data type of the property that is being rendered, and according to whether the property is marked with certain attributes. The method renders markup according to the following rules:
If the property is typed as a primitive type (integer, string, and so on), the method renders an HTML input element for a text box. For example, a property named Height that is typed as a integer might render markup such as the following:
<input class="text-box single-line"
id="Height"
name="Height"
type="text"
value="68"
/>
If a property is marked with a data-type attribute or a UIHintAttribute attribute, the attribute specifies the markup that is generated for the property. For example, if the property is marked with the MultilineText attribute, the method generates markup for a multi-line text box.
If the object contains multiple properties, for each property, the method generates a string that consists of markup for the property name and an input element to edit the property value.
