I have come unstuck with a simple compare validation.
I have the following code
<asp:TextBox ID="tbxHowMany" runat="server"
style="z-index: 1; left: 310px; top: 385px; position: absolute; text-align: center;"
Width="75px"></asp:TextBox>[code]....
So when a user enters a figure higher than 200, the validation appears.However, when I change this figure to say, 30, the validation remains. I must be doing something really stupid, I just don't know what!
UPDATE: I have also just noticed that this validation occurs when a number greater than '20' is entered into the checkbox. I'm not very confused. I am assuming this is a type issue?
I have a form with textbox for name and two dropdownlist for month and years. Textbox has Requiredfieldvalidator and the dropdowns has got ustomvalidator.Initially when i dont enter anything in the text box and leave the dropdowns with default "MM" for month and "YYYY" for year i get error message in the validation summary at top and asterisk next to the textbox and dropdowns. Once i enter some text in the textbox and focus is away from textbox the asterisk disappears but even though i hav selected a valid month and year the asterisk next to the dropdowns is not disappearing. Same problem with the radio buttons.
View 5 RepliesI have a project I'm working on, which is basically filling in a form online. The form contains multiple pages, and I have replicated this using a MultiView. On one of the pages I have a CustomValidator which validates a driving licence, based on names/previousnames and the date of birth.If the validation fails, I want to enter a link into the text, which will allow the user to click on it and correct the information that is erroneous.

I 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?

I have a validator callout extender that works, it shows the callout box. But, it does a postback. It didn't do a post back the first time I clicked the button but it did for subsequent times. I read on the AJAX site that a custom validator must be used with this for it to work. I'm currently using this with a required field and regular expression validator. It works, the callout appears, but it doesn't work every time with out the post back.I posted this to see if there is a way to get this to work with a required field and regular expression validator, with out using a custom validator. I'm using the newest release of the toolkit, so I thought the documentation may be old, since the callout is appearing.
View 8 RepliesI have a list box with data coming from the database. Above the list box I have a text box. If the user enters some text in the text box,then the data in the list box should be filtered as per the content entered in the textbox. In my page, i have about 7-8 such similar textboxes and listboxes. So I want to implement a common function which can be used for all the text boxes in the page. I tried to achieve this in textchanged event and javascript but sometimes not working. Is there any other simple way except javascript? Is it efficient to use java script in this scenario? Need your valuable inputs.
View 6 RepliesI've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.

View 3 RepliesI am using C# for ASP .NET 2.0. On my web form I have a TextBox that I want to let the end-user type inside of. The rules are as such: They should only be allowed to type numbers and a decimal. No negative numbers allowed. The number has to range from 0.00 to 24.00 - for hours - and can only allow for quarter hours - example: 0.00, 0.25, 0.50, 0.75, 1.00, 1.25, etc. Do I need a custom validator for this? If so, I do I check to see that the number is valid?
View 5 RepliesI have the current block of code inside an OnPreRender method of a validator that is inheriting from BaseValidator. If I have one instance of the validator this works fine, but if there are multiple instances the javascript flakes out. As it stands the acutal evaluation function has to be rendered on a per instance basis. I know it's kind of a drop in the bucket, but I'd like to register the block below just once instead of giving each instance a unique key to register with.

I've read quite a few posts here on this issue, but none of the solutions seem to be working for me.
I have a list box and a custom validator that is using a client side function to validate.
There is also a required field validator on the page.
Here's the markup:

So in any case, i should have an error message on the page and it should not post back, correct?
