如何使用文本框？ [英] How to use text box?

问题描述

大家好！



我想知道为什么我的文本框不接受任何特殊字符，如连字符甚至空格？这是我的代码：

Hi guys!

I am wondering why my text box do not accept any special characters such hyphen or even a space? Here is my code:

<td class="auto-style9" colspan="3" style="vertical-align: top;">
<asp:TextBox ID="txtmilestone_name" runat="server" Width="408px"></asp:TextBox>
<cc1:FilteredTextBoxExtender ID="FilteredTextBoxExtender1"  runat="server" FilterType="LowercaseLetters, UppercaseLetters" TargetControlID="txtmilestone_name" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtmilestone_name" ErrorMessage="Milestone name field required!" ForeColor="Red" ValidationGroup="m_add_validation">*</asp:RequiredFieldValidator>
</td>

请帮助我：）

Please help me :)

推荐答案

您的FilteredTextBoxExtender只允许您输入字母表。为了允许您输入特殊字符，您必须将过滤器类型设置为自定义并更改代码，如下所示。

Your FilteredTextBoxExtender will only allow you to enter alphabets. In order for you to allow it to enter special characters you will have to set the filter type to custom and change the code as follows.

<table><tbody><tr><td class="auto-style9" colspan="3" style="vertical-align: top;">
<asp:textbox id="txtmilestone_name" runat="server" width="408px" xmlns:asp="#unknown"></asp:textbox>
<cc1:filteredtextboxextender id="FilteredTextBoxExtender1" runat="server" filtertype="LowercaseLetters, UppercaseLetters, Custom" validchars="!~@-" targetcontrolid="txtmilestone_name" xmlns:cc1="#unknown" />
<asp:requiredfieldvalidator id="RequiredFieldValidator1" runat="server" controltovalidate="txtmilestone_name" errormessage="Milestone name field required!" forecolor="Red" validationgroup="m_add_validation" xmlns:asp="#unknown">*</asp:requiredfieldvalidator>
</td></tr></tbody></table>
