ConvertEmptyStringToNull Property

TemplateField.ConvertEmptyStringToNull Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets a value indicating whether the value that the TemplateField object is bound to should be converted to a null reference (Nothing in Visual Basic) if it is Empty.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public virtual bool ConvertEmptyStringToNull { get; set; }
/** @property */
public boolean get_ConvertEmptyStringToNull ()

/** @property */
public void set_ConvertEmptyStringToNull (boolean value)

public function get ConvertEmptyStringToNull () : boolean

public function set ConvertEmptyStringToNull (value : boolean)

Property Value

true if the value that the TemplateField is bound to should be converted to a null reference (Nothing in Visual Basic) when it is Empty; otherwise, false. The default value is false.

This property applies to two-way data-binding statements made in the template. The conversion is done after extracting the values from the two-way bound template, and before passing the values to the data source for an update or insertion operation.

For example, a user might enter an empty string ("") for a field value when updating or inserting records. Use the ConvertEmptyStringToNull property to specify whether an empty string value is automatically converted to a null reference (Nothing in Visual Basic) when the data field is updated in the data source.
