| Validation Class |
Validation methods for DataTables Editor fields. All of the methods
defined in this class return a delegate that can be used by
instance's method.
Each method may define its own parameters that configure how the
formatter operates. For example the `minLen` validator takes information
on the minimum length of value to accept.
Additionally each method can optionally take a
instance that controls common validation options and error messages.
The validation delegates return `null` for validate data and a string for
invalid data, with the string being the error message.

public class Validation
The Validation type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | Validation | Initializes a new instance of the Validation class |
Methods| Name | Description | |
|---|---|---|
 | Basic |
Basic validation - this is used to perform the validation provided by the
validation options only. If the validation options pass (e.g. `required`,
`empty` and `optional`) then the validation will pass regardless of the
actual value.
|
| Boolean |
Validate an input as a boolean value.
|
| DateFormat |
Check that a valid date input is given
|
| DbValues |
Check that the given value is a value that is available in a database -
i.e. a join primary key. This will attempt to automatically use the table
name and value column from the field's `Options` method (under the
assumption that it will typically be used with a joined field), but the
table and field can also be specified via the options.
|
|
Validate an input as an e-mail address.
| |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Ip |
Validate as an IP address.
|
| MaxLen |
Validate a string does not exceed a maximum length.
|
| MaxNum(Decimal, ValidationOpts) |
Check for a numeric input and that it is less than a given value.
|
| MaxNum(Decimal, String, ValidationOpts) |
Check for a numeric input and that it is less than a given value.
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MinLen |
Validate a string has a minimum length.
|
| MinMaxLen |
Require a string with a certain minimum or maximum number of characters.
|
| MinMaxNum(Decimal, Decimal, ValidationOpts) |
Check for a numeric input and that it is both less than and greater than given values
|
| MinMaxNum(Decimal, Decimal, String, ValidationOpts) |
Check for a numeric input and that it is both less than and greater than given values
|
| MinNum(Decimal, ValidationOpts) |
Check for a numeric input and that it is greater than a given value.
|
| MinNum(Decimal, String, ValidationOpts) |
Check for a numeric input and that it is greater than a given value.
|
| None |
No validation - all inputs are valid.
|
| NoTags |
Ensure that the submitted string does not contain HTML tags
|
| NotEmpty |
Optional field, but if given there must be a non-empty value

|
| UniqueT(ValidationOpts, String, String, Database) |
