First! do not define these buttons as submit buttons. Just define them as normal buttons and then check onclick. When click occurs, call a javascript and perform the validations you want. See onclick example below.
The statement above will look validatecombo1() function in scripting block. Do the same think for 2nd button but give a different name because of different validation.
I hope it works out for you!

i need to read the values in the datagrid row once the row is cliked and put them in textboxes without causing the page to postback, i tried to call a javascript function when the 'onItemCommand' event trigerred but it keep telling me (at run time) that the javascript function is not a member of the aspx page although its declared in the head tag? can you please help me.
Note: the datagrid has two rows, one is buttonColumn which i need it to cause the textboxes to be filled (its data will be filled in the first textbox), the other is a bound column that its data will be filled in the second textbox.

Hi
I need to provide the user a way to select 30 minute slots across a 24 hour 7 day period. Using checkboxes looks awful - a grid of 48 x 7 (or 7 x48 ).
Also, if they want to block out a 3 hour period for example , they have to click 6 different boxes. The same period every day of the week - 6 * 7 clicks.
Any ideas how I can represent this?
Regards
Malc

Could you do something with drag & drop? For instance, to block out a 3 hour time slot, could place a block on the screen and allow the user to grab an edge and drag to the required size...

using Divs and DHTML? I'd have to trap the event.x event.y, translate them back to screen co-ords etc wouldn't I? Sounds a tad beyond me - unless I am missing something obvious and need hitting with a blunt instrument. Can you explain a little more info, or as they say alot on these forums...
plz give me the codes man that let me do this. 
Thanks for you time.
Regards
Malc

LMGDAO!
OK - it's actually pretty simple. First thing to do is add your div at the correct place on the page. You should be able to work this out ok from your existing stuff, so all you need to do is add a div with position:absolute and top / left style attributes.
Once you have the div on the screen, you need to know if the user holds down the button on it, to start the drag operation. To do this, just add an "onmousedown" attribute which points at a function which just updates a variable to say "we're dragging now", and an onmouseup attribute which does the opposite.
OK - now we need to know when the user is dragging - to do this, we add an onmousemove handler to an appropriate object - ususally the document, but can restrict it to a "canvas" object (like a containing div) which will improve performance - the event is continually fired when moving the mouse, ,so makes sense to try to restrict it a little.
OK, the handler that we need just needs to check if we're holding down the button - which is where the mouse up / down bit comes in. If we're not dragging, then we simply return from the handler without doing anything, but if we ARE holding down the button we need to work out what to do next....
First thing is to get the current size and position of the div. We can get these from the various style attributes. Once we know how big it is currently, we work out where the mouse pointer is from event.clientX / event.clientY. From this, we can work out how wide (or tall) the div needs to be to make it extend to the current mouse position, and update it's style.width attribute.
If you need any more help, send me an email, and will see what I can do

Cheers Richard - got it working - kindof. Dragging, expanding is fine, just struggling to translate screen position to my 'duration' concept, but that's my problem now!
It will be a neat interface when it is done though (yeah and possibly a CP article, shamelessly taking all your credit) - so thanks for the help.
Thanks again.
Regards
Malc

Instead of using check boxes to select times, why not use a couple of drop down menus to let them select From time and To time?
Words fade as the meanings change, but somehow, it don't bother me.

hi! as we know that using hidden fields in web page we can preserves the string values. is there any way to preserve object reference[e.g. popup window reference] in a web page?

I always thought I'd used hidden fields in the past for this (not just strings), but I can't seem to find anywhere I did so, so I'll go with "stick it into session"

That's because you didn't. It's impossible.

That doesn't work either, as the value has to be sent to the server to be stored in a session variable, and you can't send anything but string values to the server.

Hmmmmm.....considerthe following working code snippet from our app....
<br />
DataSet ds = null;<br />
ds = fee.DraftListUnSelectedWIP(draftWriteOff, (string)Session["PEDB"]);<br />
<br />
Session["DraftWriteOffUnselectedWIP"] = ds;<br />
and then at the other end....
<br />
DataSet ds = (DataSet)Session["DraftWriteOffUnselectedWIP"];<br />
which is then bound to a grid, so seems OK. Is there some implicit casting going on that I'm not aware of

What you are doing is storing and retrieving an object in a session variable, which all takes place on the server. A window reference exists in the browser, and there is no way that you can transport that reference to the server.

You can keep the value in a Javascript variable as long as the page is loaded, but you can not keep the value if you load an new page.
If you have a frameset, you can store the value in a Javascript variable in the frameset page, and load pages in the frames in the frameset.

The function CoGetClassObjectFromURL, which is used to download the object from the web server.
In IE6, IE7 Beta 2 this works.
In IE7 RC1 it returns a status of E_NOTIMPL!!!!
Is there a work around for this in IE7-land?

Im having a problem with the menu control. Im using framework 2.0 developing a webpage in vb. The menu doesnt show on top of all of the controls. It displays behind them on some of the pages. I need a way to make sure the menu control always displays on top.

Well that's about it. I have a problem with recursion in JavaScript.
I think there's no such a thing in JavaScript. My code doesn't work
correctly , and I think this time I'm not the weak link.
So I just want to know is there recursion in JavaScript ?
I wake up with coding and go to bed with.......well Yu Gi Oh (for now).
-- modified at 15:23 Wednesday 13th September, 2006
I'm awfully sorry. There is recursion in JavaScript.
I'm truly sorry. As usual I made a mistake. Well I'm used to that.
I shouldn't have post that question. What was I thinking ?
So if you don't want to have problems with recursion in JavaScript like me
use the following syntax when using the 'for' operator:
for(var p...
Otherwise you'll have problems.
Include the 'var' part.
I didn't and wasted an hour of debugging.
 That's me after 10 hours of coding.

The variable doesn't have to be declared in the loop. You just have to declare all variables you use locally in the function.

Hello!
I have used server side includes () approach to keep organized my web pages because of some sort of complexity.
I have called "menus" what consits in several images in one of the file which is an html page within javascript. What I want is to load images of the menus first when the main page gets called. However, the the file I have included has its own HTML tags (htm,body etc.) and it is not loading the images first because of more than one file has been proccesed at same time.
How can I solve this problem with not changing the approach?
Thank You!
