I'm working on an application form for a website which implements ASP.NET validation (including client side).
I have a requirement to display a message at the bottom of the page if the client validation fails. Something along the lines of "Please go back and check your answers".
The problem is, the submit button's OnClientClick event obviously fires before the client validation.
I use validation control in my page when users click on button if they don't enter data in textboxs it show massage in validation control
I want In addition to using validation control when users click on button to insert data it show error massage thar show EX: "please complete your form"
How I can do it ?

View 2 RepliesI've got an ASP.NET webform with asp:TextBox and asp:RequiredFieldValidator at the bottom of the page. If client side validation fails on form submit - the page scrolls all the way up.
I'd like to maintain the scroll position on failed client-side validation.
I'm using the ASP.NET login control and I'm displaying a jQuery throbber when the submit button is clicked. This works fine, but the throbber is visible if client side validation fails and the button is invisible, so the user cannot re-submit the form. How do I hide the throbber if client side validation fails?

View 2 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?
View 1 RepliesLet's say that I have the following HTML for a text box on an ASP.NET page:
<div class="myClass">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>
It is easy enough to add a required field validator to this page like this.
<asp:RequiredFieldValidator ID="valMyTextBox" runat="server" ControlToValidate="txtMyTextBox" ErrorMessage="My Text Box is required."></asp:RequiredFieldValidator>
But I need to modify the HTML slightly if this text box fails validation. I need to add a CSS class to the DIV. So if the user leaves this field blank I need the HTML to look like this:
<div class="myClass error">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>
Is this possible? I can't figure out if there is a way to write code behind that only fires if this particular validator control fails validation or something. I know I can write code that runs when the entire page is not valid. But I just want this code to run when this validator returns invalid. Hope this makes sense.
The following message appears in our log:The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request. alot has been written about this subject. However, I cannot reproduce this behavior, and I only find a couple thousand errors per day in the logs; so it's probably isn't that obvious.
The page in question has an UpdatePanel and loads one of three usercontrols depending on the querystring.Is there any known issue with some clients, or any other possible explanation?
What is the best way to debug a CompareValidator that always fails the validation? Is there any way to see what the values are that it's comparing to maybe get a clue as to what's going wrong?

View 10 RepliesI am uploading a JPEG image in an ASP.NET MVC web site.
The model validation fails in IE, but passes in Firefox, when I try to check the mime type of the
HttpPostedBaseFile.
So I debuged it and I found that when using Firefox the Mime type is "image/jpeg" as expected.
When using IE8 the mime type is "image/pjpeg".
Don't say that Microsoft invented a new Mime Type of JPeg images?

When validation fails, button still postback (why ? ).

When validation fails, button still postback but then TabContainer doesn't appear (empty page is displayed, what happened to the tabs ?)
When the page has no errors, button postback the page and then every tab appears as supposed to be.
