I have a simple problem: I have a bunch of controls on a page and each one requires a validation. Also, I set control's enable=true/false programmaticaly, based on a checkbox . Now, I would like to disable the validation of a control if it is not enabled.
View 4 RepliesDoes anyone know of a way to disable validation for a step when a sidebar link is clicked?
I know there is a 'CausesValidation' property for linkbutton, but how would one apply it to the siderbar items?
So far, I've seen (and I'm using the following) scripts to show/hide a div or other controls depending on another control in ASP.NET
$('[id$=myRadio_0]').click(function() { $('[id$=myDiv]').show(); });
$('[id$=myRadio_1]').click(function() { $('[id$=myDiv]').hide(); });
and of course, my div in html like
<div id="myDiv" runat="server" visible="false">
and that works fine when the user selects either option of the radiobuttonlist. However, when I assign that radiobuttonlist a value of 1 or yes on my Page_Load on code behind, that isn't (and probably can't be) caught by jQuery, and my div remains invisible even though the control has a value of Yes/1. So, do I need to set the visibility of that div from code behind, or is there a way in jQuery to force a scan of these dependencies after i've set the values for the main controls in code behind?
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.
View 7 RepliesI've searched high and low for some resolution to this problem. Hopefully someone here can explain!!I create a usercontrol that uses .NET web controls, but I want to create a smoother user experience by avoiding full postbacks, so I write some JQUERY to capture click events on the client and in this way do the processing without going back to the server.
$("#tblLedgerEntries :checkbox").click(function () {
var value1 = $(this).closest("tr").find("td.invoiceAmount").html();
var value2 = $('#<%=hdnTotalToPay.ClientID%>').html();
CalculateTotalPayable(value1, value2, $(this).attr("checked"));

I have a page that has 3 to 4 divs with gridviews in each that get data loaded using Ajax Xmlhttp calls.
Now the problem is that I have checkboxes in the grid and need them to be disabled/enabled
when they load to the main page in the div.
When i set the Enabled=false tag in the ASPX page to the checkbox, the UI throws an "Object required" error.
I have a TabContainer, within a tab, i have a gridview, within the gridview i have a ImageButton. When I click on the ImageButton, I will call a javascript. The javascript will call a Hidden Button click. This hiddenbutton is the TargetControl of the Modalpopup so that when I click on the ImageButton, modalpopup is trigger. The Popup panal, Hidden Button and ModalPopupExtender below:

time for some expertise. I have a datalist which contains a radiobutton in the itemtemplate. This radiobutton is disabled (set enabled to false) by default. On the html output I have a checkbox, which, when ticked, enables the radiobuttons through javascript. This is all working fine. The rb's are enabled and I can check them. However when the page is posted back. The checked property is always false.
I use the code below to retrieve the value of this rb:

This code is working fine when the initial state of the radiobuttons set to enabled server side.
i'm getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
for some reason i set enableeventvalidation to false but then, its giving me problem in FF 2.0
I have a page that has a submit button which causes validation and a cancel button which does not cause validation.
When the cancel button is clicked, the button's click event handler is executed with no problem.
I would like the ESC key to do exactly what the cancel button does.
What we do is to trap the ESC key and then raise the click event for the cancel button.
Our code to handle the ESC key works fine except when the page has a validator.
When the page has a validator, the cancel button click event handler never gets called after the ESC key is pressed.
It works fine when the cancel button is clicked.
It also works fine if we do the same thing and trap any other key.
So it has something to do the ESC key and validation.
my page has two part.one part for inserting room information and anothe part is for inserting apartment information.foreach part i have some validations.i want when click in roominsert button validation in apartment part disable.

How can i disable input validation ?
I have orders page. When user submit Order, I need to disable the button to avoid multiple transactions. I also have few validation controls on the page, so button should not be disabled untill page is about to be posted. I dont have any custom javascript for validation. It is just these asp.net validation controls. What is the best way to achieve that? I have spend about 2 hours on google and found various solutions, but nothing seems to work. Each has some issue. On button I add OnClientClick="return btnOnClick this, 'Payment');" Below is what gets called. Unfortunately if I disable button, it cancels post back. So I am calling dopostback and also adding few lines on server side to see which button caused postback. It works fine in IE8 and Chrome. But for Firefox on server side arg comes null. Any ideas what is wrong with my code? Or any other suggestions to do it in a better way?
C# Server side
string arg = this.Request.Params.Get("__EVENTTARGET");
if (arg == "Payment") { this.ProcessPayment(); }
Button
<asp:Button ID="btnSubmitPO" OnClientClick="return btnOnClick(this, 'Payment');" runat="server" Text="Submit Order" ValidationGroup="G" />
alert(group);
I having a two radio button. When the second radio button is enabled, a text box which accept the email id will appear. I am validating the Email using Regular expression validator.
When the second radio button is clicked, and I enter the invalid email id so that it shows me and error. But when I click the first radio button, it is showing the save validation. I need this to not show the validation when the first radio button is clicked and invalid email id is there in the text box.
I am creating dropdown controls in code behind. in some conditions I need to add validation control to dropdowlist. But Validation not firing when I submit button.
If mQuestion.RequiredToAnswer = True Then
Dim mValidator As New RequiredFieldValidator

mValidator.InitialValue = mDDL.Items(0).Text
mValidator.Display = ValidatorDisplay.Dynamic
mValidator.ErrorMessage = "* Required!"
mTableCell.Controls.Add(mValidator)
End If

I am using the File upload control in asp.net
In that control filter option not available at least i need provide the validation for file upload control

I want DefaultModelBinder not to perform any validation based on DataAnnotations metadata. I'm already using DataAnnotations with DynamicData for the admin area of my site, and I need a different set of validation rules for the MVC based front-end. I'm decorating my classes with the MetadataType attribute. If I could have different MetadataType classes for the same model but used on different scenarios that would be great.If not I'm fine with just disabling the validation on the DefaultModelBinder, either by setting some property or by creating a specialized version of it.
View 1 Replieshow to get the total row counts in a Gridview control with default paging enabled? My gridview control is bind to an ObjectDataSource control.
The problem I am having right now is that when I loop through the gridview control, it only contains the total row for the current page being displayed on the screen and not
the total row in the entire grid. I am using the the for each loop.
foreach (GridViewRow row in this.MyGridView.Rows)
I'd like to disable ModelState validation messages and keep my data annotation error messages.
When I update model, message "The value '' is invalid." apears in ModelState. I know that I'm trying to assign null to not nullable property, but I have my own validation and message.
I use something like this
[Required(ErrorMessage="Blahblah some error")]
I want user to see my message "Blahblah some error", but not stupid message: The value '' is invalid.
I have a form where one of the fields would allow entry of HTML tags.
<asp:TextBox ID="someID" runat="server" TextMode="MultiLine" />
In this field I have a RequiredFieldValidator validation only. Unfortunately, after any PostBack if the content of any of the fields includes HTML tags or any other potentially dangerous code - the entire ViewState is cleaned.Setting ValidateRequest to false does not help. I'm using IIS 7.5 and .NET 4.0.

View 2 RepliesI have a div where I put a lot of stuff on runtime to construct a chart. The user should be able to copy the chart to another div (innerHTML) and then make som adjustments to the original div, which causes a postback. Of cours the cloned div comes back empty.
So I'm thinking of putting the entire innerHTML in a session variable at page_unload, but then I run into the validation problem. I've tried using a hiddenfield as an in-between control, but it's the same, and it seems you can't use the CausesValidation on that control. I've also tried a regular asp:textbox, but the CausesValidation doesn't have any effect.
How to do this? Or any better way all together on the copy-chart issue?
I want to check whether a control is enabled or not.
