Web Forms :: Validation Expression For Regular Expression Validator?
Feb 2, 2011I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."
ForeColor="Red" Font-Bold="True"></asp:RegularExpressionValidator>
Generating Alpha Numeric User Ids?
Mar 10, 2011I would like to generate sequential IDs in the format ZZZ999 starting from AAA001 but this is not for batch insertion of data. I want to issue the ID to users that signup on the website with the next available ID. Mutiple users can signup and should be issued the next available unique Id. I was thinking of storing the last used Id (just one row that is always updated with last issued id) in a table that I can lookup and use to determine the next id and update it. But given that mutiple users can be signing up at the same time, what is the best way to ensure that each user is issued a unique id while maintaining the issue of sequential ID. Will record locking work? I don't think so, as the last issued id can still be read by mutiple users and that it self will generate the same Id which will not work.

View 1 RepliesHTML Classes And IDs With With $ Or Non Alpha Numeric Characters?
Jan 3, 2011I'm looking at some site code on an XHTML doctype and from what I'm seeing the framework is ASP.net. The IDs in the HTML has a "$" in there. For example:
<img id="$ct100templateContent$SectionPanel1$ctl01$ctl02ctl00_templateContent_SectionPanel1_ctl01_ct999img" src="this.jpg"/>
From a W3C semantic point of view the "$" is not valid in an ID or Class. IDs and classes can only contain alpha numeric characters in an XHTML doctype.
Is the the "$" a ASP.net naming convention referencing a web control or template item?

Web Forms :: Regular Expression Validator / Add Wording To Current Expression: W+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*?
Feb 16, 2010I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.
How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*
Forms Data Controls :: Text Validator Case-sensitive / Change The Server-side validator?
Dec 13, 2010I have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?

Dec 19, 2010Is there any way to use a validator that shows an error mesagge, if the user leaves a textbox blank (empty string)? Note: in this case I can use RequiredFieldValidator, because the control I want to check for empty string is on a modalpopup (which is not visible most of the time) and the RequiredFieldValidator then blocks the Buttons on the rest of the (visible) page.

View 2 RepliesWeb Forms :: Regular Expression Validator For Both English And Chinese
May 7, 2015Earlier my text box was running on this Validation Expression="^[a-zA-Z'.s-]{1,80}$", to allow only alphabets,  ' . s . Now my text box should be capable of taking Chinese characters as well, so I was learnt online to use this p{L} for unicode instead of  a-zA-Z, and set EnableClientScript="false".
asp:RegularExpressionValidator ID="regexpName" runat="server" CssClass="failureNotification" ErrorMessage="No Special Characters allowed"
ControlToValidate="txtName" ValidationExpression="^[p{L}'.s-]{1,80}$" Display="Dynamic" meta:resourcekey="regexpNameResource1" EnableClientScript="false"
I have done both, but it doesn't work. My input values were like
1. John123 2. 汉è¯%^&
Both of these were accepted without any errors. But I expect only alphabets in english and chinese and ' . s - to be accepted as Name input.
