I need to get the name of the file the user selects from the input type file control and display it on to the page. The javascript onchange event does not work in ie 7 but works well in ie 8. The same is with the case in jquery change() function.
View 2 RepliesI am having fileupload control having its "multiple" attribute equals to "multiple". I am facing a weird issue in CHROME browser. The isse is that onchange event of file upload control is not firing for more than 12 files selected at once. The event is firing if I have 10 files selected at once. On FF and Safari it is working fine. Here is the code:
<html xmlns="http://www.w3.org/1999/xhtml">

I have TextBox which
id="test" AutoPostBack="true" OnTextChanged="server event"...
On Client Side I write logic if fail prevent Server Event fire.
I try
[code]....
I can see the alert fire, but can not prevent the server side event fire.
i have a dropdownlist whose autopostback = true , but for some selected text i do want tht the autopostback really shouldnt fire .. using jquery...
however i hav really tried out using removeAttr() to remove attribute and then evt.preventDefault() which ofcourse should prevent the postback...
also tried to set the evt.returnValue = false so that the value returned by the dropdownlist change event is false ...
d code snippet i tried out is like :
[Code]....
none of the above resulted in stopping the postback..
I'm working on an ASP.NET web application for our corporate intranet users. I have a form where a user should provide a path to the file on the local network (something like "localServersomeFoldersomeFile.ext") without uploading the actual file. The issue is that users don't want to type the whole file path and want to use some kind of visual browse dialog.
The standard HTML <input type=file> element allows to browse for a file, but most of the browsers (except for IE) don't allow to access file's full path, so I think it should be done by some external component like Silverlight, Flash, Java applet etc. I tried to do it with Silverlight, but I'm getting a SecurityException when trying to access file's full path using Silverlight's OpenFileDialog class. This java applet [URL] seems to do something similar to what I'm looking for, but it's focused on uploading files - I only need to be able to get file's full path and pass it to the server as a string.
I am trying to streamline the look of my site and I was wondering if there was a way to use the onclick of an image to open up a <input type="file.../>? I want the input to be invisible so it doesn't add clutter to the interface. Here is ultimatly the flow I would ideally have... Image click -> Javascript calls input open. User clicks "open" in the dialog, Input calls some Javascript that calls the click event of the inviable "upload" button. Boom. User clicks image, selects a new one, and I have it automatically on my server without the need for two more buttons... Anyone know if these types of events/functions exists and if so what they are called and how to capture them? Or should I stop making this over complicated and use the method that I know works?
View 6 RepliesI have an ASP.NET Webform and inside the form I have an input type of file. What I would like to happen is for the form to post immediately after the user chooses a file.I have a server side function I would like to be called, let's say UploadedFile()What is the easiest way to accomplish this?
View 1 RepliesI am using the <input type="file" /> tag to upload a file to the server. How do I access the file at the server side and store it at the server? (The file is an image file)The client side code is :
<form id="form1" action="PhotoStore.aspx" enctype="multipart/form-data">
<div>
<input type="file" id="file" onchange="preview(this)" />

AsyncFileUpload control is rendering in this way.
<span
id="Span1"><input
type="hidden"
name="uploadinput$ctl00"
id="uploadinput_ctl00"
/><div
id="uploadinput_ctl01"
name="uploadinput_ctl01"><input
name="uploadinput$ctl02"
type="file"
id="uploadinput_ctl02"
id="uploadinput_ctl02" onkeydown="return false;"
onkeypress="return false;"
onmousedown="return false;"
style="width:
355px;"
/></div></span>
Is there any way to assign styles(like width, position,top etc..) to Input type=file element alone.One way i can see, is using Jquery document.ready eventhandler,
$(function(){
var element = document.getElementById('<%=uploadinput.ClientID%>').lastChild.firstChild;
element.style.width = '150px';
but the problem with that is, i am not able to identify input type = file element after postback in that document.ready eventhandler.please let me know if there is any other way to assign styles to input file element of AsyncFileUpload control with out any issues.
I have a input of type file and when i try to do a Request.files when the input is wrapped in an update panel...it always returns an empty httpfilecollection. Why???

I got this error message ,The value 'xxx' is not valid for AgeHowever, I want to change this message and try many way. There 's nothing effect this message value.
I am trying to get the path of a file from an Input type="file" and at the minute all i can get is the file name using

anyone know how to get the path?
I have 3 security question drop down menus. I have javascript on the ASPX page that removes questions/repopulates them when you select a questions (so you cannot reselect the questions in the other 2 boxes). This works wonderfully when a user is editing their profile with already selected questions. However, when a user first selects the questions where all three boxes are listing "select a question" at selectedIndex 0, the onChange doesn't fire. The function won't even go. I think this has a big something to do with the on change from selected index of 0. I have debugged this thing and it doesn't even enter the function. I even set the onchange action to flash an alert. It just seems something is going wrong when i try to action onchange from selected index of 0.

View 3 RepliesI have to create a HtmlInputText control in code and while in code set it so that it will respond to text changes purely on the client side and not generate a server side event. In an aspx page this would be done like so:
<input id="txtBox" runat="server" onchange="clientsidefunction();">
But in creating this control I cannot determine anyway of setting the onchange client side event. I can setup a server side event by entering:
AddHandler txtBox.ServerChange, AddressOf.serversidefunction Is there anyway to set the clientside onchange event?

My forst post here + I am new to Asp.Net as well. 2nd my apologies if this question has been asked before.
Here is my problem. I am given some really abstract ASP.net pages, where I have to make a change. My change involves adding some links and on each link I have a function which is triggered when link is clicked on. This function validates some information in the form and then submits this form. This same form contains mulitple list boxes, all of them has AutoPostBack=true. The problem is when I select an item from listbox the form is submitted as I can print all the form properies on the page(all fields with their names and values) however, when I click on link and call the same forms submit(); method I dont see that happening. none of the form fields are printed out.
Now once I click on listbox and select an item after that as long as that item is selected, I can click on all links and they all call the submit() method of the form and it produces required resutls. I am really baffled as this doesnt seem correct as far as simple html is concerend.
I m trying to stop the postback causing by ddl. I have tried the following code but still pb doesnt stop:
<script type="text/javascript" language="javascript">
var ddlSubCategory = document.getElementById("ctl00_m_g_73a5a887_bd36_4a37_966a_ed640c804a84_ctl00_ctl04_ctl09_ctl00_ctl00_ctl04_ctl00_ctl00_SubCategory"); //Get this form html source
ddlSubCategory.removeAttribute("onchange"); //Here "onchange" attribute causes post back
</script>

I am working on making a Sharepoint 2007 app look more modern. I am using jQuery actively for that and even though I am no expert, I have learnt enough to know my ways around. Untill I faced this issue today. Here are the bits:
$(document).ready(function() {
alert('doc ready');
var textBox1 = $("#myTest");
alert(textBox1);
textBox1.keyup(function() {
alert('key UP');
});
textBox1.live("keyup", function() {
alert('keykeykey up live');
});
});
Server-generated html:
<input name="ctl00$Spwebpartmanager1$g_1f2d211c_a0c3_490d_8890_028afd098cac$ctl00$myTest" type="password" id="ctl00_Spwebpartmanager1_g_1f2d211c_a0c3_490d_8890_028afd098cac_ctl00_myTest" class="gh" />
So the document ready handler fires, the textbox1 variable is not null, but none of the eventhandlers to handle the keyup event ever fire?
