SPField.ValidateAndParseValue method

SharePoint 2013

When overridden in a derived class, validates and parses the input value and returns a valid object that can be the value of the field.

Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

public virtual Object ValidateAndParseValue(
	SPListItem item,
	string value


Type: Microsoft.SharePoint.SPListItem

An SPListItem containing a field whose new value needs to be validated.

Type: System.String

A string with the value to be parsed and returned.

Return value

Type: System.Object
An object that can be assigned to the field as its value.


Item is a null reference (Nothing in Visual Basic).

The default implementation doesn't do any validating, it simply returns the value.

Consider overriding the ParseValue(SPListItem, String) method and calling it as part of your override of this method.
