Hello All,

I want to Convert Textbox value into Uppercase and it should be display in uppercase.

so I have just use

<pre lang="xml"><asp:TextBox ID="txtno" runat="server" SkinID="text" MaxLength="19" onblur="this.value=this.value.toUpperCase();"></asp:TextBox>

并且我已在该文本框&上应用了RegularExpressionValidator通过Validatorcallout Extender显示错误消息，

它在IE中正常工作，但是当我在任意位置按Tab/单击时，它会显示错误消息，但textbox fullfil critria却总是显示错误消息，

请给我建议.

 <cc1:ValidatorCalloutExtender ID="vceOAHCaseNo" runat="server" TargetControlID="revOAHCasNo"WarningIconImageUrl="../Images/Error.png"></cc1:ValidatorCalloutExtender>

推荐答案

我认为这应该有效:

I think this ought to work:

\D{3}-\D{3}
or
([A-Z]{3}\-){2}[A-Z]{4}\-\d{5}\-\d{4}

我会试试:

I would try :

<asp:RegularExpressionValidator ... ValidationExpression="^FM-[a-z,A-Z]{4}\-[0-9]{2}\-[0-9]{2}\-[0-9]{5}
