I wasn't sure if this should go in Web Dev or ASP.
I'm using a DataList that contains JavaScript in order to fill some textboxes. The DataList pops up in a modal div dialog, and the user clicks an item, filling in two fields on the page. This works fine. The problem occurs when I try to get the values in the code-behind. The values are empty, even though they do in fact contain text on the page. If the user types in their own values, it works like it should. Here's the code.
JavaScript:
function fillLookupField(control, value) {
document.getElementById(getClientId(control)).value = value;
}
getClientId() just returns the ClientId so that the control can be accessed from the JavaScript. Here is part of it:
function getClientId(control) {
switch (control) {
case 'BonusCost':
return '<%= txtBonusCost.ClientId %>';
case 'BonusDesc':
return '<%= txtBonusDesc.ClientId %>';
This is the code-behind for the submit button click:
Dim amount As Integer = Val(txtBonusCost.Text)
Dim desc As String = txtBonusDesc.Text
MsgBox(amount & vbTab & desc)
The message box just displays a zero, so the value of an empty String concatenated with another empty String. I've tried making a hidden field and setting its input the same way, and I have the same issue. Any ideas?

Have you looked at the Page Source from the Browser to see what your server generated javascript getClientId has in it?

Yes, and it's good. Again, the textboxes DO have the text in them as they should when the JavaScript executes.

Ok, next wild guess is that you have some code initializing the values to empty in an operation that executes prior to the button event handler in the page life cycle sequence.

No, I don't. I just tried something else that may be helpful or at least interesting. I typed in the values and submitted the form and it worked as it did before. I then used the JavaScript to set its value, but it retained the old value, even though there was a new value in the textbox from the JS. (The old value persisted from the ViewState and was present in the textbox when the page loaded.) Once the page loads, the old values are the ones restored from the ViewState into the textboxes.
If that paragraph doesn't make sense:
1. Values (call them "old values") typed in.
2. Submitted ok, old values detected in code-behind as they should be.
3. Page loads with old values in textboxes.
4. JavaScript inserts new values into textboxes, and they are visually present.
5. Code-behind picks up old values, not the new ones.
6. Page loads with old values in textboxes.

Evan, we could go on like this forever and never get near a solution. Texting is not conducive to debugging. While it is entirely possible you are thoroughly debugging the application, you are not giving that impression in your posts. If in fact you have not performed such work, I strongly suggest you do. Debugging is how you find out exactly what is happening rather than just guessing.

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

I've debugged this as well as I can think to. JavaScript can't be "debugged" per se, as far as I know. And at any rate, I'm confident the JS itself is not the problem. I'm just wondering if anyone knows of a difference between an HTML input's value property and the ASP TextBox's Text property. Or maybe something with the page lifecycle.
If you have any advice on what I should specifically look at to debug these issues, I'd be glad to hear it.

please let me explain what my problem is and if you can answer that'd be very useful!
1. I am establishing a membership site and want all members to have an email address associated with the domain when they signup, with pop3/imap and a web access to this mail
2. When they signup to the membership site they will type their name and a desired mailbox or alias, for example if our site was called "website.com" and when John signs up he will want "john@website.com"
so he types this into the page on signup and gets his mailbox account created automatically through an API functioning system,
so there is no manual creations.
I am presently talking to hosting companies but not having much luck, if you know of a solution or method, please share!
Best Regards,

Hi,
im using Wshell.Regwrite to write registry(vb script) through html page...
but it works fine only when the option "Initialize and script ActiveX
controls not marked as safe" under Tools\internet
options/Security/Customlevel/ActiveX controls and plugIns ,is set to prompt or enable .....and if we set to any other option ie(disable) it fails ie it shows error like .. "ActiveX component cannot create object "Wscript.shell"...
So May i know whether is it possible to create my own ActiveX control(signed) with certificate so that it doesn"t depend on internet options..
if yes pls let me know how to do the same...
pls correct me if im wrong...

I have an existing ASP application on a single server www.server1.com.
This app. gets its data from an ACCESS MDB using Remote Scripting (I know its legacy!) and is running within shared-web space.
Is it possible using this/or any other technology to retreive data held in this Access MDB from another web server e.g. server2.com. and if so, how?

The error code for the failure is 80004005.
This error can be caused when the worker process account has
insufficient rights to read the .NET Framework files.
Please ensure that the .NET Framework is correctly installed and
that the ACLs on the installation directory

Did you try to reinstall ASP.NET? Use aspnet_regiis.exe -i within the v2.0-framework directory (can be found in Windows\Microsoft.NET\Framework.

Thanx for ur reply..SeMartens.
Actually there is nothing any problem of ASP.NET.
I think its an IIS problem..so I tried after IIS ReInstallation.
But Problem could not solved.
as just something I think about the Temporary Internet Files.
and..
My Problem has solved after Deleting the temporary folder for my WEBSITE from
"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\"

Victory
