Web Forms :: Validation Summary Appears After Postback?
Mar 8, 2011
i have many validators but one validator RFVRIDDORReferenceId is enabled and disabled through javascript. because txtReferenceId is shown when something is selected from a dropdownlist. initially it is disabled. everything was working fine until i implemented EDIT functionality in which through an ID i need to load page and show everything...on serverside i enabled
RFVRIDDORReferenceId.Enabled = true;
if ReferenceId database field had value in it. other wise it stays like that. after loading the information on page and disable RFVRIDDORReferenceId through client side...press save button and everything will be updated but when page comes back validation summary has
Following errors occured
> ReferenceId is required
it displays in red i dont know why it is doing it....(postback itself shows that all validators were true). is there any reason?
does validator validate themselve after postback? if yes then why does not remaining validators shows error message?
PS: its a required field validator and there are many other but validation summary shows only for this validator.
This control is used multiple times on one aspx page. The issue is that each time an instance of the control is validated due to a text change any prior error messages are cleared from the validation summary. I want the validation summary to maintain prior error messages during the postback.
I am using one datalist control for uploading multiple images.I hv used one Asp:FileUplaod Control and one button in one itemtemplate.I am using reqired field validator and regular expression validator for file upload cntrl I am assigning validation group for both of them on ItemDataBound event of my datalist so that each upload cntrl hv same validaton group as required field and regular expression validator.Now what i want to do is - i want to show my error message in validation summary which is right at the top of the page.I want one know how to write javascript that will assign validation group of my control in datalist on which i click ?
I have the following markup. The errorPanel was first only used to show server side exception messages, and works fine like that. Now I'd like to incorporate my validation summary into that same errorPanel.
[code]....
My problem now is that the required validation happens client side, and I want to keep that, so I have no server side opportunity to make errorPanel visible, in order to make the validation summary visible.
I see I have two options: Do validation server side, and use my code there to make the panel visible, or hook into the client side code somehow and catch an event there when the summary should be made visible, and then also make the errorPanel visible. How could I go about the latter?
I've added a CompareValidator and ValidationSummary to a web page. The CompareValidator is working fine, but the validation summary never shows up even if I force a post back. I've verified that both controls have their ValidationGroup property set to the same value. Is there anything else that would cause this behavior?
I use the oob client side validation from mvc 2 RC. The input field validation errors are working fine. But the validation summary is missing. How to get the validation summary on client side validation?
I´m using different validation controls from asp.net in a page that has like 10 controls. When I click on insert validation occurs but my problem is that error messages appear in summary for some and other validation only takes place when I correct the first errors which is very confusing. I´m trying to get all validation messages to be shown all at once but for some reason not all of them happen at the same time.
[Code]....
I tried to figure out a solution by assigning ordered tab index, but behaviour keeps the same. Some controls appear to be validated first with their respective error messages whereas others are validated after the firts ones.
what i want to do is to set up different validation summary for different type of validators. for example, for required field validators, if user leaves some required field blank, it shows that "You have to fill in mandantory information, indicated with a star"
and if some format is wrong, it shows that "format is invalid"
right now, i set all requied field validators' text to be a star, and leave error message to be blank. so that the validation summart will only display the header message. that is what i need. what i dont know is how to separate regular expression into another summary.
i think the validation group property requires multiple buttons. however, i only want one submit button, and this is where i got stuck.
The ValidationSummary panel shows up, even if the validator does not have an 'ErrorMessage'. When I click on Submit with invalid login, the error shows up in summary. That part's fine. When I submit with empty textboxes, it should show only the '*', but it also shows an empty summary panel. How can I prevent this. [Have a css class for .summary,header, summary ul, .summary ul li].
JS:
function validateTextBox(sender, args) { var target = document.getElementById(sender.controltovalidate); var is_valid = target.value != "";
I am using asp.net validation controls in my application. the alert messages are showing in validation summary. now i should change the title(heading) of the alert(message) box.how to do this ?
I am using User controls in my web page. I have validation controls in my user control and the validation summary control is placed in the master page. Problem is I am not getting the errors displayed when I am running my application.
We have option in validation summary to show errors in messagebox. But at the same time errors also showed in the page. Any way to hide this. Because of page space i think to use popup but i dont want to siplay in the summary also.
i am working on web-form for which I have set the validation summary showmessagebox = "true".
I have two required field validators, which trigger on a checkbox's OnCheckedChanged event....now my problem is, when I hit submit, the page does not submit if I do not enter any values in the text boxes..which is correct behavior but it does not point out to the error or does not display the message box.
i have to scroll up to see what is wrong with he page and then try to enter the values...I do not understand why my message box does not show up or at least why my setfocusonerror which is set to true does
I have a validation summary (vs) and required field validator (rfv) on my page. The validation groups are not set in either of the controls. When I leave javascript on, the rfv fires correctly and the error message appears in the vs, as well as a * appearing next to the textbox I am validating. When I set the EnableClientScript=False for the rfv (forcing a postback and server side validate), the * appears, but the error message doe not appear in the vs. Why is the error not appearing in the vs? The fact that the * is appearing shows that the validator is being fired.
How can i use Javascript to dispaly the error msg in validation summary . i have the validation summary in master page, and would like to add some error msg if i find some custom errors.
I created some required field validators and a validation summary control. When I get an error it displays next to the control its validating and also inside the validation summary control. I only want the error to display in one place; inside the validation summary control. I tried making the required field validator invisible but then it didn't display anywhere.How can I get the errors to only display in the validation summary control? There is no need to display them twice it just clutters up the page.
I am using a MultiView control inside a FormView to break my form into more manageable sections for the end-user. I am trying to make it so that each time the Next button is clicked, the entire form is validated and a list of the fields that have not yet been completed show up in the Validation Summary.
I would like my users to be able to continue through the MultiView 'wizard' even if they haven't completed all the fields -- they should be able to come back to them later. But I would like the ValidationSummary to display the fields they've not completed that are required as a reminder of what to come back to if possible.
I've tried playing around with Page.IsValid with no success.
[Code]....
The code-behind for the Next button is as follows:
I have an aspx page, where there are 2 validation summaries. One for master (at the top of page) & one for details (at the bottom). On details validation, the focus just shifts on top of the page and not on my validation summary in details section. How to do this
I'm using ASP.NET MVC 2, DataAnnotation and MicrosoftMvcValidation.js for validation. I have two forms in my view..is there a way to use validation summary like in ASP.NET Webforms.
