Does A Custom Validator Have To Be Used With The Validator Callout Extender
Jul 6, 2010I 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.

Basically, I compile the below code into a DLL and add it to my bin folder.

View 5 RepliesWeb Forms :: Custom Validator - Valid Number?
Mar 12, 2010I 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 RepliesWeb Forms :: Can't Have Multiple Instances Of A Custom Validator
Feb 8, 2011I 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.

Web Forms :: Custom Validator With A Listbox Not Working?
