Web Forms :: Assistance Required On Modifying A Validation Expression?
Oct 27, 2010
I have found a very useful validation expression at http://regexlib.com/DisplayPatterns.aspx?cattabindex=2&categoryId=3 However, I want to make a couple of changes but am struggling a little!!
As per the link, this "regular expression will match on a real / decimal / floating point / numeric string with no more than 2 digits past the decimal. The negative sign (-) is allowed. No leading zeroes or commas. It is based on a currency regular expression
by Tom Persing."
I would like to modify this as follows:
- Not match on numbers above 999
- Allow up to 5 digits past the decimal
and I would like to modify my sort expression so that when the expirydate header is clicked on, it will make all those id that has expired pop to the top . In this case, we will have the following as the results
I am using a regex to detect forum tags within posts, such as "[quote]text[/quote]" and then replace them with HTML formatting. I posted a question Forum tags. What is the best way to implement them? about a problem with nested tags.
Right now this matches an opening and closing tag, with match groups for the tag name, the tag content, and an optional value like the value after the equals in this forum tag [url=www.google.com]click me[/url].
What I need is for the expression to match the opening tag OR the closing tag and have a match group containing the tag name (including the '/' for the closing tag). I then want to iterate through them sort of like this:
Dictionary<string, int> tagCollection = new Dictionary<string, int>(); inputString = Regex.Replace(inputString, @"expression I'm asking for here", match => {
[Code]....
So now, each tag is appended with a number and I could use the original regex to perform the tag functions and properly handle nested tags as separate tags.

We are using regular expression and required field validators. They work fine, especially in out of the box environments like the log in control.
When used on other controls, e.g. a textbox, they also work, but we note that the whole site is in effect shut down until the expression is valid. I.e. the user cannot click cancel, or a link. The site only starts working again after the expression has been made valid.
How can this be fixed?
The validators should only apply to the control to validate and to the control that would cause the value of that control to be posted back to the server (e.g. a button), not the whole site.
I have a regular expression validation set on text box. I have a grid on the same page with edit and delete buttons. In some cases I don't want the regular expression to fire. For example, I have a scenario where the text box will be disabled but I can still enter data in to the grid and modify it, but the regular expression fires when I modify the grid and the changes in the grid are not processed.how can I stop the validation when I am working on grid. I can see a property causes validation for button to stop validation but don't know how can I stop for the grid.

I'm trying to use a field validator to make sure one of my list boxes has a selection before the user is able to proceed to the next page. i'm having is that if the validation message is triggered, all of the buttons on my page loose functionality.Meaning, if I purposely trigger the validation control, I can't get rid of the error message and none of my buttons do anything when clicke after this.
The majority of the HTML:
[Code]....
Is there something that I need to add to the code behind of the page or the Java Script that I'm using?
I have a web forms where i have 10 required field validators for 10 textboxes. Validation group for these required field validator needs to be determined when the page loads. I tried to change the validator in the .cs file but failed.
