在asp.net中清空MaskedEditExtender [英] empty MaskedEditExtender in asp.net

问题描述

如果我的MaskedEditExtender在文本框中为空它将保存，但它会显示错误消息



当输入的数字无效时，应该出现错误信息。 />


MaskedEditExtender应该只在数字为invlid时工作

请帮帮我

解决方案

< blockquote> MaskedEditExtender仅允许有效数据，如果你想在按键上显示错误信息，请使用javascript或MaskedEditValidator。



< asp：textbox id =TextBox1runat =serverxmlns：asp =＃unknown>

< asp：maskededitextender id =TextBox1_MaskedEditExtenderrunat =serverxmlns：asp =＃unknown>

CultureAMPMPlaceholder =CultureCurrencySymbolPlaceholder =

CultureDateFormat =CultureDatePlaceholder =CultureDecimalPlaceholder =

CultureThousandsPlaceholder =CultureTimePlaceholder =已启用=真

Mask =999999999M askType =NumberTargetControlID =TextBox1>

if my MaskedEditExtender is empty on textbox the it will be save but it giving error message

error message should be come when the enter number is invalid.

MaskedEditExtender should be working only when the number is invlid
please help me

解决方案

MaskedEditExtender allows only valid data, if u want to display error message on keypress, use javascript or MaskedEditValidator.

<asp:textbox id="TextBox1" runat="server" xmlns:asp="#unknown">
<asp:maskededitextender id="TextBox1_MaskedEditExtender" runat="server" xmlns:asp="#unknown">
CultureAMPMPlaceholder="" CultureCurrencySymbolPlaceholder=""
CultureDateFormat="" CultureDatePlaceholder="" CultureDecimalPlaceholder=""
CultureThousandsPlaceholder="" CultureTimePlaceholder="" Enabled="True"
Mask="999999999" MaskType="Number" TargetControlID="TextBox1">
