Web Forms :: Assistance Required On Modifying A Validation Expression?
Oct 27, 2010I 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!!
The expression is:
^[-]?([1-9]{1}[0-9]{0,}(.[0-9]{0,2})?|0(.[0-9]{0,2})?|.[0-9]{1,2})$
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

Web Forms :: Validation Summary Message Box Does Not Pop-up For A Required Field Validator
May 10, 2010i am working on web-form for which I have set the validation summary showmessagebox = "true".
I have two required field validators, which trigger on a checkbox's OnCheckedChanged event....now my problem is, when I hit submit, the page does not submit if I do not enter any values in the text boxes..which is correct behavior but it does not point out to the error or does not display the message box.
i have to scroll up to see what is wrong with he page and then try to enter the values...I do not understand why my message box does not show up or at least why my setfocusonerror which is set to true does
not show me the text boxes...
find my code below...

Web Forms :: Separate Validation Summaries Required For Insert And Edit Controls
Apr 12, 2010I did the data access tutorials on this site.They used validation controls for the insert and the edit template fields. Each of these used their own validation summary control. The markup for them is below. Can I use the same validation summary control for both the insert and the edit validation controls? It seems redundant if i can set the Validation Group property to the same value then I would only need to use one validation summary.I don't know if this is allowed, or a good idea though.

Web Forms :: Created Some Required Field Validators And A Validation Summary Control?
Feb 24, 2011I created some required field validators and a validation summary control. When I get an error it displays next to the control its validating and also inside the validation summary control. I only want the error to display in one place; inside the validation summary control. I tried making the required field validator invisible but then it didn't display anywhere.How can I get the errors to only display in the validation summary control? There is no need to display them twice it just clutters up the page.
View 3 RepliesConditional Required Attribute For Validation?
Mar 23, 2010We're trying to get a conditional attribute to work, case in point, there's a boolean (checkbox) that if checked, its related text is required. So, ideally we'd have something like ...
public bool Provision { get; set; }
[ConditionalRequirement(IsNeededWhenTrue = Provision)]
public string ProvisionText { get; set; }
Is this even possible?
Alternate idea (not as elegant?)
public bool Provision2 { get; set; }
[PropertyRequired(RequiredBooleanPropertyName = "Provision2")]
public string Provision2Text { get; set; }
I'd hate to use the magic string method .
