Hello all,
I have a situation and I'd appreciate it if any of you could help me. I am not sure if this is js or html but here goes. I have a main combo box (mcb) which I'm displaying some values.
Based on what the user chooses, 2 combo boxes should be displayed on same page. The first combo box (CB1), should be filled with some values. The second, (CB2) however, should get loaded on basis of what is chosen in CB1. UNtil then, CB2 should be empty (but visible). When user chooses a value in CB1, and then CB2, a 3rd combo box, CB3 should be displayed. CB3 will have values already, based on what is chosen in CB2. If use decides not to select any value from CB2, CB3 is not displayed at all.
Until now, this is what I have done.
1. I have the main combo box (mcb).
2. In Onchange event of mcb, CB1 and CB2 get displayed. CB1 has values, CB2 does not.
3. In OnChange of CB1, CB2 gets populated.
Thats all. Now I want a CB3 to be displayed with values in it, depending on if and what the user chooses in CB2.
Can anyone help? :)
Thanks!

are you using AJAX or normal ASP.NET stuff?
Neither. Just js, html and php.
bind dataview to your CB3..
use DataView.RowFil ter to filter it each time, when user change value of CB2..
and bind it to CB3 again..
ohh.. sorry... i thought you are a .NET developer..
use AJAX in such cases.. it will make your life simple.. :)
there are several good articles here like this
I see... is there anyway to do it with js and html? I don't know Ajax and I'm guessing it'll take me time to understand it and write code for my scenario.

it would only be sensible, if the total content is not too much (because you have to supply all the data for the combo boxes along with the page load).

Thank you. That is what I was thinking too, if I'm only going to use js and html AND want to be on same page.
In which case, it is about 4200 records. (Is that a lot?) If yes, then is Ajax my only hope? :(

I would say so, you’d better use AJAX in this case.

Hello all,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
