RangeValidator 類別

定義

檢查輸入控制項的值是否在指定的值範圍內。Checks whether the value of an input control is within a specified range of values.

public ref class RangeValidator : System::Web::UI::WebControls::BaseCompareValidator
public class RangeValidator : System.Web.UI.WebControls.BaseCompareValidator
type RangeValidator = class
    inherit BaseCompareValidator
Public Class RangeValidator
Inherits BaseCompareValidator

範例

下列範例示範如何 RangeValidator 在網頁上建立控制項,以判斷輸入控制項中輸入的值是否在比較範圍內。The following example demonstrates how to create a RangeValidator control on the Web page to determine whether the value entered into an input control is within the comparison range.

重要

這個範例有一個可接受使用者輸入的文字方塊,這可能會造成安全性威脅。This example has a text box that accepts user input, which is a potential security threat. 根據預設,ASP.NET Web 網頁會驗證使用者輸入未包含指令碼或 HTML 項目。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 如需詳細資訊,請參閱 Script Exploits Overview (指令碼攻擊概觀)。For more information, see Script Exploits Overview.

備註

RangeValidator控制項會測試輸入控制項的值是否在指定的範圍內。The RangeValidator control tests whether the value of an input control is within a specified range.

RangeValidator控制項使用四個主要屬性來執行其驗證。The RangeValidator control uses four key properties to perform its validation. ControlToValidate屬性包含要驗證的輸入控制項。The ControlToValidate property contains the input control to validate. MinimumValueMaximumValue 屬性會指定有效範圍的最小值和最大值。The MinimumValue and MaximumValue properties specify the minimum and maximum values of the valid range.

BaseCompareValidator.Type屬性可用來指定要比較之值的資料類型。The BaseCompareValidator.Type property is used to specify the data type of the values to compare. 在執行驗證作業之前,要比較的值會轉換成這個資料類型。The values to compare are converted to this data type before the validation operation is performed.

注意

Type 屬性設定為 Date ,且目前的行事曆類型是非西曆時,驗證程式只會執行伺服器端驗證。When the Type property is set to Date and the current calendar type is non-Gregorian, the validator performs server-side validation only. 驗證程式用戶端腳本僅支援西曆行事曆。The validator client script supports only Gregorian calendars.

下表列出可比較的不同資料類型。The following table lists the different data types that can be compared.

資料類型Data Type 描述Description
String 字串資料型別。A string data type.
Integer 32 位元帶正負號的整數資料型別。A 32-bit signed integer data type.
Double 雙精確度浮點數資料類型。A double-precision floating point number data type.
Date 日期資料型別。A date data type.
Currency 十進位資料類型,可包含貨幣符號。A decimal data type that can contain currency symbols.

注意

如果輸入控制項是空的,驗證就會成功。Validation succeeds if the input control is empty. 使用 RequiredFieldValidator 控制項,讓輸入控制項成為必要欄位。Use a RequiredFieldValidator control to make the input control a mandatory field.

注意

RangeValidator如果或屬性指定的值 MaximumValue MinimumValue 無法轉換成指定的,控制項會擲回例外狀況 BaseCompareValidator.TypeThe RangeValidator control throws an exception if the value specified by the MaximumValue or MinimumValue property cannot be converted to the specified BaseCompareValidator.Type.

注意

當您在 RangeValidator 控制項內使用控制項時 UpdatePanel ,請確定驗證程式控制項和與其相關聯的控制項都在相同的面板中。When you use the RangeValidator control inside an UpdatePanel control, make sure that the validator control and the control it is associated with are in the same panel. 如需使用 UpdatePanel 控制項進行部分頁面更新的詳細資訊,請參閱 部分網頁呈現總覽For more information about using the UpdatePanel control for partial-page updates, see Partial-Page Rendering Overview.

如需驗證控制項的詳細資訊,請參閱 BaseValidatorFor additional information on validation controls, see BaseValidator.
