Forms Data Controls :: Javascript Validation For Assigning Validation Group To Validation Summary On Datalist Item Click?
Dec 25, 2010
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 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?
n a form I have multiple group of controls which are grouped using validation group property. I want to assign validation group to asp.Button dynamically on client side using javascript on the base of item selected in drop down list.
Here is JavaScript which I am using, but it is not working. It shows validation group undefined but actually a default group is defined.
<script type="text/JavaScript"> function NextClicked() { var _ddlStatus = document.getElementById("<%=ddl.ClientID%>"); var _selectedIndex = _ddlStatus.selectedIndex; var _btn = document.getElementById("<%=btnNext.ClientID%>");
alert(_btn.ValidationGroup); // here in messge it shows undefiend, yet I have defiend a group in button as default.
if (_selectedIndex == 1) { _btn.ValidationGroup = "G1"; } if (_selectedIndex == 2) { _btn.ValidationGroup = "G2"; } }
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?
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.
How can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.
I've made an ASP.NET web form that uses the standard ASP.NET validation. I'd like to make the error summary show up in a jQuery UI Modal Message as well as below the actual form.Is it possible to execute the script if the validation finds an error?
I have few controls which r validated for blank on a page having 5 buttons
I want the validation to take place only on save button click & not on any other button
<asp:ValidationSummary ID="ValidationSummary1" HeaderText="You must enter a value in the following fields:" EnableClientScript="true" ShowMessageBox="true" ShowSummary="false" DisplayMode="BulletList" runat="server" />
Is it possible to do client side validation on a detailsview (insert or edit) without using validation controls? I.E. somehow capture the onClientClick event of the autogenerated Insert/Update link buttons to call my javascript function?
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?
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.
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.
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'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?
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.
