Could not map property LanguageBranch - table tblBigTable does not contain any columns that map I have a problem with copy/paste action in the episerver tree. . When this field in the XForm editor is unchecked, the user can only submit the form once. I'm working with EpiServer CMS 6 on the az-links.info platform. We all have a love-hate relationship with XForms in EPiServer. it's not part of the XForm, you need to put it above your form or at the bottom below it fully and it was a quick throw-together for another project I'm working on. Episerver CMS does not support the client-side functionality that may be before the form is posted by setting the "EnableClientScript = true" on the XFormControl .. mary has a sense of meaning and direction in her life and a relationship to a.

DataTypes class The DataTypes class contains information on all the data types available for form fields. These are contained in a public property, Types, which is basically a hash table.

The hash table simply contains keys and values, where keys are the unique key for the data type and the value is a regular expression. When posting form data, all input will be validated against the regular expression for the data type of the input control. If no data type has been specified for the control, the data will be validated against the public string property InvalidDefaultInputRegex. The reason for having a default validation is to prevent malicious data being posted from a form.

XFormControl is a web control that is used to display an XForms form and makes sure that the input is validated.

The class exposes a public method, SubmitFormto be able to submit form data. The form itself does not trigger the actual posting. This is handled by any existing submit web controls in the form, which is also why it is possible to have several buttons on the same form that may trigger different actions.

Of course, it is also possible to call this method from the code. What happens when the form is loaded? The BeforeLoadingForm event is triggered. For instance, you could replace the table structure with a div structure by applying regular expressions to the form content. Document property is parsed by Page. The parsed controls are added as child controls. For fields that have validation, validation control s are added and connected to the corresponding web control.

ControlsCreated is a triggered public event. It is possible to alter the appearence and function of the form at this time.

Rendering of the form takes place.

What happens when data is submitted? The SubmitForm event for a submit control is triggered. The SubmitForm method is called with the channel options set on the submit control. See section Sending Form Data below for more information on available channels. Validation will take place to ensure that rules about anonymous users and multiple postings from the same user are followed.

If there are validation errors against these rules, StaticValidators will be added to the Page. Validators collection to ensure that validation errors will be thrown. A StaticValidator is a validator that will always give a validation error. BeforeReadingPostedData is a triggered public event and Page.

Validate is called for the current validation group. Often you want to do both. Creating a custom property to store a certain type of value is something that can significantly improve the quality of parts of our code as it helps us fight the code smell known as primitive obsession where primitive data types are used as substitutes for classes.

Requirements for an EPiServer property The minimum that any class that represents a property must do is to inherit from the abstract PropertyData class. However, properties must also be registered with the system. Whenever EPiServer starts up, such as after recompilation or a modification to web. Custom property development patterns Reuse through inheritance While, as we just saw, the minimum requirement for a custom property is to inherit from the PropertyData class it is common to instead inherit from one of the built in property types when creating custom properties.

This is also something that the EPiServer developers themselves have done quite a lot. In fact, looking at the specialized properties found in the EPiServer. SpecializedProperties namespace none of the inherits directly from PropertyData but from either one of the system property types or from another type of specialized property.

Likewise, if we for instance were to develop a property that would store a number we could probably reuse a lot of functionality from the PropertyNumber class by inheriting from it.

How to create a custom EPiServer property

Exposing the value in a strongly typed way Another thing that is commonly done when developing custom EPiServer properties, especially in those that EPiServer themselves provide, is to expose the value in an additional property of the actual type of the value, as opposed to the Value property that is of type Object. This is in no way a mandatory practice but it is usually convenient to follow this pattern as it makes it easier to access the value of the property in the control that is used for editing it as it removes the need to cast the Value code property.

Likewise, it also provides strongly typed access to the value for other members of the custom property class. Therefore, when using this pattern its common to put any code that should be executed upon getting or setting the value inside the strongly typed property instead of inside the Value property to ensure that it will always be executed.

Serializing the value to a string Yet another common pattern for custom property development is to create properties whose value is some custom class and serialize it to a string when its saved.

The PropertyLinkCollection class is one such example among the built-in properties. While it's common to inherit from a more specific class than PropertyData when creating a custom property studying the PropertyData class provides good insight into how the property model works, knowledge that can be invaluable if we run into problems.

Abstract methods that must be implemented PropertyData has a big interface comprised of many methods and properties. Six of these are abstract, meaning that we must implement them if we create a property type that inherits directly from PropertyData. It can be considered the reverse of the ToString method.

The ParseToSelf method should also parse a string representation of the property but instead of returning an instance of the property it should retrieve the value from the parsed property and assign it to itself. This indicated by returning a value from the enum named PropertyDataType. The PropertyDataType defines eleven valid types, one of which is obsolete:
