I have a problem, with my validators.
I have validation on a contactform, to ensure spam, but my problem is, when I go to the page and want to go back to the default site, it won't let me, because of the validators. Nothing has been written in the textboxes and the "Send" button hasn't been clicked.
Anyone who have an idea, for what I can do?
If you are going "back" with a specific button instead of the browser's back button, set CausesValidation="false" in the attributes of the button.
This might be due to a button / any other submitting control you click to go back which has CausesValidation set to true? This property will cause all your validatorControls to perform a check and as a consequence, if there is any invalid control/value prevent the user from changing page.
Hitting the Back-Button in your browser is possible at any time and cannot be prevented by a validatorControl.

I have some input fields, regular expression validators, and custom validators inside an ASP.NET ASCX control. The behavior is a bit odd in that it works the following way:
If a client side validator flags an error message and I tab away from the input field and click submit then the page posts as it should. However, if a client side validator has flagged an error and instead I correct the error and click submit button then the error is cleared but the page is not submitted until I click the submit button a second time.
My question is how do I change this behavior such that I only need to click the submit button once to both clear the error and postback the page? Also, is this "behavior" standard?
Update: This behavior occurs without using the user control. I believe it is specific behavior to the CompareValidator. Nope, same behavior occurs with custom validator. If I don't "tab away" and click the button then I must click it twice to get the postback to occur. The first click just clears the validators.
The issue is that the CustomValidator has display type as Dynamic and not Static. This post helped me to discover the answer
RequiredFieldValidator have to click twice
I will give credit for anyone who explains why it causes this behavior.
I have a couple of pages with standard asp.net validation controls such as RequiredFieldValidator etc inside my RadAjaxPanel.
As soon as I navigate to another tab in my RadTabStrip the page seems to force validation errors and pretty much "locks" the page even though non of the fields was selected to enter data.
Only once all the required fields was entered the page seems to release the "lock" and only then am I able to navigate to another tab / page without even submitting the page.
Any idea what might be causing the "lock" and forced validation errors on the page?
Thanks
The RequiredFieldValidators are failing as the fields are empty. These validators are fired client side and so they're stopping the postback (which will change your tab) from occurring.
I'm not sure how the tabbing works on a RadTabStrip, but for normal ASP Buttons there's a "CausesValidation" property on the button. If you set it to false, it'll stop any validators from being fired when pressed.
I have used AJAXToolkit AutoComplete extender in my project.It works fines.But the issue is with the form of the page.
when i type in the AutoComplete, i get list of suggestions.When i click on the page other than the Autocomplete, the form gets submitted.
any suggestions how to stop submission of entire form whenever i click on the page?I use .net 2.0
Does your TextBox have AutoPostBack="True" set? If so, it will automatically postback when you're "finished" (when the input control loses focus). If this is the case, just set it to false.
yeah,My TextBox AutoPostBack was set to true which i have changed it to false, now.
but i have a url attached to each of my suggestions.On click of suggestion, user gets navigated to that particular url. When i do AutoPostback= "false", i wont get navigated to that page.
HOw do i handle it?
I think it would be as simple as adding a required validator to your element to see if the user selected anything.

Use jquery to add an event handler that detects clicks. When a click occurs, stop the browser. Let me know if you need code.
I have one aspx page that has two UserControls on it; each is primarily a ModalPopupExtender. One has validators; one does not. The one that does not has a Submit button with the CausesValidation="false" attribute on it.
When that Submit button is clicked, nothing happens. Click it again, and the postback happens as expected. There is clearly some validation issue going on here, because if I remove all validators from the page, the postback succeeds on the first click.
What's going on here?
Without seeing the code, I can't say this for certain, but it sounds like you may need to utilize the validation groups. The validation group would be set on the validation components as well as the button that posts back the page.
Make sure that the buttons that show the ModalPopups are marked CausesValidation=false as well. What was happening was that the "Show Dialog" button for the non-validating dialog was not marked this way; this was causing the entire page to validate when that dialog was shown - including the other dialog, which did have validation and was failing it. This caused the Submit button to fail for apparently no reason.
Moral of the story: Make sure to use CausesValidation on any buttons that don't require it, and use Validation Groups to separate out various page parts, especially when parts of the page are not visible.
Have you tried removing the OK button property from the modal popup?
I am using a cross page postback for Page A to pass data to Page B.
The button that causes the postback has its postbackurl set but is disabled until the user selects a value from a DDL at which point the button is enable using javascript. However this prevents the cross page postback from occurring, Page A just postbacks to itself.
If the button is never disabled it works fine. Anyone know how to solve this?
It looks like when the button is disabled .Net doesn't bother adding the necessary bits to handle the cross page postback on the client, so they will be missing when the button is enable client-side.
I guess one solution would be to have the button enabled to start with (so that .Net adds the cross page postback controls) and then disable it using javascript as soon as the control loads on the client. But this sounds a bit clunky.
