1. 常用的货币格式化字符串
string
s
=
salary.ToString(
"
##,##0.00
"
);
2. GridView 中日期、数字的格式化,需要加一个 HtmlEncode="false" 才能奏效。
日期:
<
asp:BoundField
DataField
="FromDate"
HeaderText
="开始时间"
DataFormatString
="{0:yyyy-MM-dd}"
HtmlEncode
="false"
/>
数字:
<
asp:BoundField
DataField
="平均分"
HeaderText
="平均分"
DataFormatString
="{0:##,##0.00}"
HtmlEncode
="false"
/>
3. GridView 中带确认信息的 DeleteButton
<
asp:TemplateField
>
<
ItemTemplate
>
<
asp:LinkButton
ID
="LinkButton1"
runat
="server"
CommandName
="Delete"
OnClientClick
="return confirm('您确认要删除吗?')"
CausesValidation
="false"
>
删除
</
asp:LinkButton
>
</
ItemTemplate
>
</
asp:TemplateField
>
4. 典型的时间输入的校验
<
asp:TextBox
ID
="txtFromDate"
runat
="server"
ValidationGroup
="vgp1"
/> (格式:1978-10-11)
<
asp:RequiredFieldValidator
ID
="reqFromDate"
runat
="server"
ControlToValidate
="txtFromDate"
ErrorMessage
="请输入开始时间"
ValidationGroup
="vgp1"
/>
<
asp:CustomValidator
ID
="cvFromDate"
runat
="server"
ControlToValidate
="txtFromDate"
OnServerValidate
="Validate_Date"
ErrorMessage
="开始时间的格式不正确。(例:1978-01-02)"
ValidationGroup
="vgp1"
/>
<
script language
=
"
javascript
"
type
=
"
text/javascript
"
>
//
客户端日期验证函数
function
Validate_Date_Client(src, e)
{
e.IsValid
=
/^
\d{
4
}
-
\d{
2
}
-
\d{
2
}$
/
.test(e.Value);
}
</
script
>
//
服务器端日期验证
protected
void
Validate_Date(
object
source, ServerValidateEventArgs e)
{
e.IsValid
=
true
;
try
{
DateTime dt
=
DateTime.Parse(e.Value);
}
catch
{
e.IsValid
=
false
;
}
}
