C# Class Castle.MonoRail.Framework.Helpers.FormHelper

The FormHelper allows you to output html input elements using the conventions necessary to use the DataBinder on the server side. Ultimately it allows you do to a bi-directional binding -- if used properly.

FormValidation
The following operations are related to the Form Validation support:

FormTag(IDictionary) and EndFormTag Opens/close the form tag. They are required to use the form validation DisableValidation Disables validation altogether UseWebValidatorProvider Sets a custom Browser validator provider UsePrototypeValidation Configures the helper to use the prototype easy field validation. Must be invoked before FormTag UsefValidate Configures the helper to use the fValidate. Deprecated. UseZebdaValidation Configures the helper to use the Zebda. Must be invoked before FormTag

Mask support.
For most elements, you can use the entries mask and optionally mask_separator to define a mask for your inputs. Kudos to mordechai Sandhaus - 52action.com

For example: mask='2,5',mask_separator='/' will mask the content to '12/34/1234'

AjaxFormTag ( IDictionary parameters ) : string	Generate Ajax form tag for ajax based form submission. Experimental.
Button ( string value ) : string	Generates an input button element.
Button ( string value, IDictionary attributes ) : string	Generates an input button element.
ButtonElement ( string innerText ) : string	Creates a basic button element of type submit.
ButtonElement ( string innerText, string type ) : string	Creates a basic button element of the specified type.
ButtonElement ( string innerText, string type, IDictionary attributes ) : string	Creates a basic button element of the specified type and with specified attributes.
CheckboxField ( string target ) : string	Generates a checkbox field. In fact it generates two as a way to send a value if the primary checkbox is not checked. This allow the process the be aware of the unchecked value and act accordingly.
CheckboxField ( string target, IDictionary attributes ) : string	Generates a checkbox field. In fact it generates two as a way to send a value if the primary checkbox is not checked. This allow the process the be aware of the unchecked value and act accordingly. The checked and unchecked values sent to the server defaults to true and false. You can override them using the parameters `trueValue` and `falseValue`, but the DataBinder is prepared only to treat boolean arrays.
CreateCheckboxList ( string target, IEnumerable dataSource ) : CheckboxList	Creates a CheckboxList instance which is enumerable. For each interaction you can invoke CheckboxList.Item() which will correctly render a checkbox input element for the current element on the supplied set (`dataSource`). The enumerable item will be an element of the `dataSource`. If the `dataSource` elements are complex objects (ie not string or primitives), supply the parameters `value` and `text` to the dictionary to make the helper use the specified properties to extract the `option` value and content respectively. Usually both the `target` and obviously the `dataSource` are sets with multiple items. The element types tend to be the same. If they are not, you might have to specify the `suffix` parameters on the `attributes` as it would not be inferred.

Select() public method

Creates a select element and its options based on the dataSource. If the dataSource elements are complex objects (ie not string or primitives), supply the parameters value and text to the dictionary to make the helper use the specified properties to extract the option value and content respectively.

You can also specify the attribute firstoption to force the first option be something like 'please select'. You can set the value of firstoption by specifying the attribute firstoptionvalue. The default value is '0'.

Usually the target is a single value and the dataSource is obviously a set with multiple items. The element types tend to be the same. If they are not, you might have to specify the suffix parameters on the attributes as it would not be inferred.

The target can also be a set. In this case the intersection will be the initially selected elements.
