I have a form with my own JQuery validation. When a JQuery <button id=btnRegister type=submit> is clicked, my validation code is invoked and if invalid, form does not submit. All works great. I have another <button id=btnSave> on this form. I would like btnSave to fire asp.net server side event (onserverclick) only if form data is valid. I have tried following -
<button type=submit onclick='if($(this).closest('form').submit()==false) return;' onserverclick='btnSave_click' runat =server>Save</button>
When I click on the btnSave, it does invoke my form's submit event handler, which correctly returns false, if invalid. So far so good. After this point, I would like the onserverclick event not trigger. However, the onserverclick does trigger and the page posts back, even when the form is invalid. As I see it, cannot have onclick and onserverclick at the same time. What should I do to make them co-exist harmoniously? If I change <button> to <input type=submit> it all works out. But I like <button>'s look and feel more.
I've got an UpdatePanel nested in a Panel control. I'm using a ModalPopupExtender to "popup" the UpdatePanel which provides a list control that a user can select from, which places the selected item in a textbox. This part works fine, but if I select items and click on the CancelControl or OkControl each control is triggering validation on some of the other controls on the page and not triggering the click event. I'm not using validation at this point, but put all the other controls in a validationgroup, but it didn't work. If I don't select any listbox items and click on the CancelControl or OkControl, they behave as expected. Here is a sample of what my panels generally look like:
I want to use the JQuery FancyBox on an asp.net page but all the examples I have found show triggering a fancybox from anchor tag (< a >). I am not able to find an example where a fancybox is triggered from codebehind. To be more specific, I create a pdf file on the fly on a LinkButton click. After the file has been created, I want to show it using fancybox (I am using Jquery and FancyBox for the first time). Any examples showing how to do this will be much appreciated. PS: Fancybox is not must. Any JQuery plugin that will show the pdf in a popup will do.

But this time I am stuck because my hidden_link control exists inside a dynamically loaded user control, and I do not know it's id, as the id's change to something like this:
I am using Literal1.Text = "<script>jQuery(document).ready(function() {$("a[id$='hidden_link2']").trigger('click');});</script>"; (which would find an <a> tag ending with hidden_link2) but this only triggers the fancybox for the first user control. How can I inject this script for the required <a> link only? Hope that makes sense.
jQuery validation is working fine on my machine, when i pushed it to test server it won't it's throwing some errors which is kind of surprising.These are the errors I am getting: $.validator is null or not an object...I've never gotten this error before and it throwing an error when I declared a variable like var isValid.I don't know what to do. I am doing the custom validation methods not in the document.ready(). Does this cause this error? I wonder because all jquery validations are passing and hitting the server side validations.
Im using the ms validation blocks to validate user input posted using jquery (ajax). Can someone give me an example of the best way to inform the user that the data does not validate.
Do i simply throw an exception and use the error event of the $.ajax function to inform the user of the issues or is there a better way of handling this?
I could also write every validation for each object separately, I have only a few elements who uses a required validation but it would be nice that I could do this in one shot instead of repeating the $("input").rules("add .....
But when I have a ListView or DataView, etc... with a pager, I get problems when I click on 'next page'.Then I get the error: Validation of viewstate MAC failed. When I don't use Jquery's load function, I don't get an error.
and ValidateMyform will validate on each button click...
var objPost = args.get_postBackElement(); if (objPost === null || objPost === undefined) return; if (objPost.type == 'submit') {[code].....
Here I want to get back the page to normal stage(like after a full page postback)...even though after async postback the validation is still active...it should not get back to normal and its throwing errors if i enter something wrong...this is because the page is not fully refreshed on asyc postbacks...I just want get the like the normal after each asyc post back...
I tried using submit and reset to reset the page but its became to normal..the validation is still active...I have no idea what to do..
has anyone implemented date range vaildation using jquery.validate file? when i m trying to implement it with mvc application its not working properly , as its working only for numeric types. wl range validator of jquery validate only numeric values ?
I have created the validation using jquery in my asp.netform with post mehtod.but i have replicate the same in usercontrol.But in useroncontrol i dont have any form and i cant give any action and any post mehtod. how to do validation using jquery in usercontrol.
Here's what is in my .aspx: <div> <input id="testButton" type="image" src="<%=TestImageUrl %>" onserverclick="RedirectTest" /> </div>
And in my code-behind this: protected void RedirectTest(object sender, EventArgs e) { // Logic is here}
It's not hitting my method at all when I click the image. And please note, I do not want to use an ImageButton. I want to figure out how to get this working with a plain old input tag.
The event is simply not firing, what am I missing?
Code for the button: <input type="button" class="button hide" id="savetext" style="float:right;" value="Hello" runat="server" OnServerClick="savetext_Click"/>
And the code that is generated (i.e. when opened in a browser and the source is viewed) is this: <input onclick="__doPostBack('ctl00$Main$savetext','')" name="ctl00$Main$savetext" type="button" id="savetext" style="float:right;" class="button hide" value="Save to text" />
I've got <pages clientIDMode="Static" /> in web.config but the name and generated onclick event are prefixed despite that. Server side code: Protected Sub savetext_Click(ByVal sender As Object, ByVal e As System.EventArgs) End Sub
To be clear, my goal is to register a click on a button server-side, not just client-side.
This works fine, but when I add an onclick event: <button type="submit" runat="server" onserverclick="btnNext_Click" onclick="return checkForm();" id="btnNext">Next > </button>
And in the head: <script type="text/javascript"> function checkForm() { if (document.getElementById("<%=lstChooseSpec.ClientID %>").value) { return true; } else { $.jGrowl("<strong>Warning!</strong><br />Please select an item", { sticky: true }); return false; } } </script>
It submits the form, but doesn't change the buttons text to 'CLICK'. The text only changes to 'CLICK' when the onclick() isn't defined, although the form is still submitting!
In our application we have multiple instances of the same form in different tabs (one tab for each client). We use the MVC2 jquery validation to validate these forms, using the Html.textboxFor and Html.ValidationMessageFor elements.
The problem exhibits itself when we have two tabs. When we give wrong input in the second form (second tab), the validationmessage is shown on the (closed) first tab. It seems that the validation message is linked to the ID of the validationmessage (and thus only linked to the first form), and not to the combination of the form with the ID.
I have moved form the toolkit tabcontainer to jquery tabs. Now I consider to change the asp.net validation controls for jquery.The jquery validator uses the form element as container of all fields. However, I only use one asp.net form element which contains 'multiple' forms (a group of fields represent a form; one on each tab).Can I activate the jquery validator on a something else than a form element? I tried a div element, but this did not work.
$("#mydiv").validate()
In asp.net we have the validation group attribute to indicate the boundaries of a 'form'.
i have a checkbox and dropdown in a gridview when user selects checkbox only then he can select the dropdown, and the dropdown wil have the values corresponding to the gridview rows count if user checks two checkbox in a gridview,and the dropdown value should be diffrent it should be not the same for the selected checkbox how to achieve this using Jquery and asp.net
I would like to replicate this functionality with the asp:DropDownList control i.e. I have several dropdowns which I would like to call the same code behind routine. However it seems that asp controls do not support the OnServerClick option. Is there a way to explicitly define which code behind routine to call on an asp control?
I have been experiencing some very strange behavior using html buttons with the onserverclick attribute. What I am trying to do is use jQuery to designate the default button on the page. By default button I mean the button that is "clicked" when a user hits enter. In testing, I would hit enter while in an input field and sometimes the intended "default" button was clicked and the server side method defined in the corresponding onserverclick attribute was hit. Other times a post back was made without hitting the server method. In order to isolate the issue I created a minimal test case and found some very interesting results.
Client side: [Code] ....
Server side: public partial class admin_spikes_ButtonSubmitTest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void ServerMethod1(object sender, EventArgs e) { _response.Text = "server method1 was hit"; } protected void ServerMethod2(object sender, EventArgs e) { _response.Text = "server method2 was hit"; } }
What I found was that everything worked as expected with this code except when I removed one of the input elements. In Firefox 3.6 and IE 8 when only one input exists on the page, hitting enter does not trigger the onserverclick, it makes a post back without even being jQuery "clicked" or actually "clicked". You can test this by starting with two inputs and clicking "test2". This will output "server method2 was hit". Then just hit enter and the output will be "server method1 was hit. Now take away an input and run the same test. Click "test2" see the results, then hit enter and you will see that nothing will change because the "test1" method was never hit. Chrome worked as expected
I would like to do the validation work using javascript or jquery in onclientclick and then show blockUI, next page using server click. But, I have a captcha validation in server click and I don't know how to validate the captcha in jquery or javascript.
protected void btnRegister_Click(object sender, EventArgs e) { lblMessage.Text = ""; if (Page.IsValid) { if (txtUserName.Text == "") { lblMessage.Text = "نام کاربری را وارد نمائید"; txtUserName.Focus(); return; } if (!BLL.IsStrictPassword(txtPassword.Text)) { lblMessage.Text = "طول کلمه عبور حداقل باید 5 کاراکتر باشد"; txtPassword.Focus(); return; } if (ddlYear.Text == "<سال>" || ddlMonth.Text == "<ماه>" || ddlDay.Text == "<روز>") { lblMessage.Text = "لطفا تاریخ تولدتان را وارد نمائید"; return; } if (!chk_Low.Checked) { lblMessage.Text = "برای عضویت می بایست قوانین سایت را بپذیرید"; return; } if (txtSecurityCode.Text == String.Empty) { .Text = "کد امنیتی را وارد نکرده اید"; txtSecurityCode.Focus(); return; } secCode.ValidateCaptcha(txtSecurityCode.Text); if (!secCode.UserValidated) { lblMessage.Text = "کد امنیتی نادرست وارد شده است"; return; } try { //some code } }
When I write the code for Each HtmlAnchor a in Me.Master.FindControls("link" + i) AddHandler e.OnServerClick, AddressOf OnClick end for I get an error that OnServerClick event is protected and I cannot access it. The question is how do I dynamically add event handlers to HtmlAnchor controls?
I've created some dynamic buttons on page load but the buttons need to have an onserverclick event and pass a value. I used buttons because they can pass a value. My code below so far, just outputs onserverlick to the html page, which is obviously not what I want. Would it be possible to use some other method, I originally used hyperlinks until I needed to pass a value (I didn't want to use querystrings). [Code]....
