I've written a JavaScript function which validates form input and highlights the input fields and displays any error messages, which I have tested and all works fine. i have called this function from the OnClientClick attribute of an asp:Button tag. However, if the JavaScript function determines there to be validation errors, I want to stop the form from submitting. How do I do this?

I am making my site compatible to all browsers.For that on one page i am selecting the name from dropdownlist and on click of VIEW(button),i want to open a new window .i also want to send the value and text of ddl on new window. all of this i want to do on onClientClick or onClick of button...
for getting the value i hv tried this code:-
input name="button1" type="button" id="btnview" style="cursor:hand" class="Buttons" title="View" value="View" onclick="alert(document.all('<%=ddlScheme.ClientID%>').value);"
[Code]....
I am a little confused to use this script and how it actually works?Here is my script:
<script type="text/javascript">
$(document).ready(function () {
$('#<%=TextBox1.ClientID%>').change(function () {
$('#various3').attr('href', $(this).val());
});
[Code]...
Now if I click the button it should open the iframe and display the message which I am able to do.Now the problem is how do I call the button1_Click event which is in the codebehind at the same time. I have used OnClick and OnClientClick event as shown below but it's not working and I'm not getting any errors.
I've noticed there is no OnClientClick() property for the radiobuttonlist in the ASP.NET control set. Is this a purposeful omissiong on Microsoft's part? Anyway, I've tried to add OnClick to the radio button list like so:
For Each li As ListItem In rblSearch.Items
li.Attributes.Add("OnClick", "javascript:alert('jon');")
Next
But alas, it doesn't work. I've even checked the source in firebug, and there is no javascript shown in the radiobuttonlist. I'm using ASP.NET control adapters so don't know if that has anything to do with it. (I wish asp.net/javascript would just work out the box!!!)
I'd like to know if there are other ways to write a submission program (submitting urls or pad xml to directories, submission sites, blogs) other than using the webBrowser. I've evaluated some shareware programs that submit urls or data very quickly, like 100s in a matter of mins. I couldn't write a program using a webBrowser because it might take 15 secs just to load the url. How are they writing the code??

HOW TO RUN THE JAVASCRIPT FUNCTION ON PAGE ONLOAD EVENT IN CONTENT PAGE OF MASTER PAGE.? means i have masterpage and the content page of master page namely default.aspx in vb.net.i wanna run javascript function in Default.aspx and i have called the function body onload in master page.when i run my website it shows the error "" Microsoft JScript Runtime Error : Object Expected ""
View 4 RepliesI have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

View 1 RepliesI have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.
I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

I have a bit of code that jumps around a few domains and adds a user to each of them. This follow is a piece of code I had to write to get around the issue of the .add and .invoke being ran asynchronously and occasionally causing errors.
It connects to the domain in question, passing a "CN" from the code in as a search filter but receives a COMException which is normally a LDAP sting config issue. The connection string in this is fine so I am not sure why it is having such a hard time.

I have built a vb.net web application. I have tried to make it secure, with all users requiring a password to get in. The only problem is that if anyone can guess (or detect using some kind of hacking tools) the url of the javascript file, they can download it and read it, without even having to log in first.
Is there any way that this can be prevented?

I am using Synclock to prevent multiple threads from logging text messages to the same file at the same time, but this doesn't seem to work:I get frequent sharing errors on the logfile, within the synclock block.The Synclock is using the variable holding the filename, because it exists all the time and because it is always the same object, whatever class instance or thread I'm in.[code]Despite using Synclock and a Using block around the code, I keep getting this error in the sw.WriteLine(Msg) line:System.IO.IOException: The process cannot access the file '(filename)' because it is being used by another process.Should I use some other type of object than a string to synchronize on?I cannot use a user interface object (button or so) because it is a windows service project.It was written and compiled in Visual Studio 2008, but targeting the 2.0 framework because it has to be able to run on some old Win2000 machines.
