I have added the .dll file in my project's BIN folder and for Matt Gibb's solution I have also added the tagMapping code to web.config file. But for both of the solution, when I ran the project I noticed it doesn't have any effect on the validation controls.

View 1 RepliesAm trying to implement some sort of validation on a text box, that users would input dates into. I need help on writing VB code, such that when users fill there date of birth into the text box, it prevents them from putting a date in the future. Also for a text box that requires a date in the future, the validation should prevent them from picking a date in the past.

I have worked with the .MVC framework using validation frameworks such as xVal or FluentValidation.
Is there anything similar available for webforms as well? I have got a few projects which have to be done using webforms.
What I'm asking for is some kind of integration with the webforms infrastructure. I could just use one of the mentioned frameworks in order to validate the (view/page)models, but I still would have to do a lot of form validation in the page.
I want to call some web-service webmethods on asp.net submit button's click in order to validate the form regarding to some business logic and then I would like to have the button to go on its default behavior if the validation is OK.
How can I stop the aspx page to post-back (after submit button click) and continue submitting the form only if it is allowed by the 'success' function of jQuery.ajax()'s option parameter?

<script src="js/jquery.validate.js" type="text/javascript"></script>

I know this question has been asked million times but I think my situation is different here.I am using .NET Framework 3.5 SP1, there is no form action on the page and it's not happening when I try to submit the form quickly. I am not on a web farm either.I have a page with two GridViews. One Gridview acts as a master gridview and second as detail gridview. First Gridview has autogenerate select button and clicking select would bring related records in detail gridview at the bottom. I have a refresh Link button at the top. Everything works fine. I click refresh button and it works fine too.Ok when problem start happening when I leave the page idle for like 10 minutes or so and then I click Refresh button only then I get this "Validation of Viewstate MAC failed" error.
View 1 RepliesI have a form that I have been getting submissions that have punctuation and special characters that trigger the potentially dangerous Request.Form value error. I have been trying use the httpUtility.htmlencode and Server.htmlencode method to sanitize textboxes and textareas.All my tests do not fire because the built-in request validation of the 4.0 framework prevents the code-behind from executing to perform the sanitization. I have included the ValidateRequest in the page header but no matter what I set it too it still does the same thing.
This is the code I have so far.
Session("RequestID") = Server.HtmlEncode(txtRequestID.Value)
Session("FirstName") = Server.HtmlEncode(txtInstFirstName.Text)
Session("LastName") = Server.HtmlEncode(txtInstLastName.Text) [code]....
What can I do to make this work? According to all the websites I have visited it should work.
do you have validation using HTML5 and also I am using with Master Page.

View 10 RepliesI am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?
