Hi!
I just started working a bit with web the other day. I was just playing around, making an aspx-page with a asp:DropDownList and a asp:Button. I populated the dropdownlist with a couple of posts. Based on current post in dropdownlist I wanted different things to happen when I clicked the button. Only problem is, selectedindex on dropdownlist is always -1. The page is somehow reset even before I get to register what actually happened on it. What am I doing wrong?

Two issues
1 - you should have asked in teh ASP.NET forum
2 - odds are high you're setting the data source of the control in your page load every time. This resets the selected index. Use IsPOstback to do it once, and also try to do binding in the prerender event

Any thoughts?
I'd like to set up a tiny file sharing site (work documents etc) with uploading and file listing. However it needs to have some access control so that only permissioned users can upload/download. Is there a decent method (example?) of doing this without having to rely on web server folder permissions?
Thx++

You could use Subversion, which not only gives you a reasonably fine-grained permissions system if you don't like Apache's, but also gives you versioning...

Hiya,
Are you using ASP.NET? Or some kind of CGI (Common Gateway Interface) app?

Hiya,
In ASP.NET you could always try the Login component??

Nice try, buddy. That crap doesn't work on the web, and for good reason.

HI ALL,
Now I am facing a problem with webservice callback.We called a webmethod asynchronously from a webpage.Then the page will be rendered from the server to the client,but the result of the called method may be reaches the webservice after rendering the site.So the webservice become not able to send the result to webform.My question is how to inform the webform asynchronously without polling for its completion and too much delay?
Plz Help................
|
|
|
|

The whole point of asynchronous calls is that you get notified when they're done. If you're gonna return before it's done, then you've left yourself no choice but to poll in some fashion.
I suggest you go for a long walk, and ponder the motivations behind building asynchronous HTTP request support into browsers...

Hi,
I use repeater to list data from database. Once the repeater is populated, I want to get the column width for each column in the repeater table in javascript function. I am trying to do in table's onresize event. The code is shown as below:
...
<script type="text/javaScript">
function getColumnWidth()
{
alert("List the width of each table column");
//get the width of column and do something
}
</script>
<table id="tbTableBody" onresize="getColumnWidth()" >
<asp:Repeater id="rptAccounts" runat="server" >
<ItemTemplate >
<tr>
<td>Field1 value </td>
<td>Field2 value </td>
<td>Field3 value </td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>
...
However, onresize event doesn't fire at all. If I use onmousemove, instead of onresize, the javascript function getColumnWidth() will get executed. But if the page is loaded, but the user doesn't move the mouse, then the javascript function will not be able to executed.
Does anyone know what I need to do to make it work?
Thanks in advance!

Hi,
How do I set a confirm box's title, in Fire Fox it just says [JavaScript Application]. It looks horrible.
I hope to hear from someone soon.

You can't. It's a security feature of JavaScript to stop web pages pretending to be something else.

That's what confirm boxes in Firefox look like. No one is forcing you to use them, but if you do then you play by the rules.
Sorry - it could have been better, but a bunch of assholes with no consideration for their users or others ruined it for everyone. See also the "Automation" question above...

Add an onclick="functionName();" to your input tag.

Hi,
Below is the code of my body tag. The checkForChange method is called twice, why is this? I only need it to be called once. What it needs to do is to check if a textbox was changed, if so then it must display a message, but the message needs to be displayed if the user wants to go to another page if data was changed.
<body onbeforeunload="checkForChange();" >
<input type="text" onchange="isDirty = true;" />
<input type="submit" name="btnCancel" value="Cancel" id="btnCancel" onclick="return checkForChange();" />
<br /><br /><br /><br />
<a href="Link.htm">LinkLinkLinkLinkLinkLinkLinkLink</a>
<script language="javascript" type="text/javascript">
var isDirty = false;
function checkForChange()
{
if (isDirty)
return confirm('Changes have been made.');
else
return true;
}
</script>
</body>
If the user clicks cancel, it should stay on the current page, but if it clicks ok, then it should move to the next page. Currently the massge boz is displayed twice, and it doesn't matter what is clicked it still goes to the next page (on the link that was clicked).
Please can someone help.
Thanks
Brendan

The code below works fine in IE 6.0. Perhaps it can solve your problem.
<head>
<script type="text/javascript">
var isDirty = false;
function checkForChange() {
if (isDirty) {
alert("Changes have been made.");
}
}
function moveToNext() {
if (isDirty) {
if(confirm('Move to next page...')) {
var myLink = document.getElementById('myLink');
myLink.href='Link.htm';
myLink.click();
}
}
}
</script>
</head>
<body>
<input type="text" onchange="isDirty=true;" />
<input type="submit" name="btnCancel" value="Cancel" id="btnCancel" onclick="javascript:checkForChange();"/>
<br /><br /><br /><br />
<a id="myLink" href="javascript:moveToNext();">LinkLinkLinkLinkLinkLinkLinkLink</a>
</body>

Hi All
I am trying to allow one to three (3) files to be uploaded to a server, then send an email to the recipient for verification.
The files upload correctly and the email is sent, however it sends three emails for the one upload process.
What do I need to change in the code so that I only send one email for the complete process?
Any help would be appreciated.
Regards
Robert Caya
Here is the code for the process ...
