I'm not sure how to exactly ask this, but expect that it's a Javascript
solution. However, I'll ask the question and maybe someone can point
me to some existing code that will do what I need.
I have an Asp.Net app that's in 2.0 framework. I have a page that is
sort of a storefront sort of page that has a product, a quantity and a
button for "Add To Cart" and one for "Add To Wishlist".
I'd like to disable those two buttons if the quantity is not greater
than zero.
Can someone help?

use compare-validators for things like this - these will validate data on
the client-side. Set your button's CausesValidatio n-property to True, add a
compare-validator for each textbox, linking them to another. If you need
several different validation-groups, use the ValidationGroup-properties. If
you'd rather like to display a single message (as opposed to or in addition
to showing error-messages right next to the control), use a
ValidationSumma ry-control.
Cheers,
Olaf

Off the top of my head without seeing your code: I suppose you could
default the buttons to be disabled and fire the "TextChange d" event
when a value is entered in a quantity textbox or the
"SelectedIndexC hanged" event if it is a drop down list. In these
events, you can then enable the buttons. You will probably need to put
code in the events to check if your qty is greater than 0 or not and
enable/disable accordingly (the user may remove items from cart as well
as add?).

Olaf's advice looks good. Validators are ideal for situations like
this.
I believe they want to enable/disable buttons and not display messages
when the qty is 0. Please advise on how to do this with validators.

thing is, you'd need server-side code in order to actually enable the
button. If there's a client-side-way of dealing with this (i.e. enabling a
control), then I'd sure like to know ...

??? You can enable / disable a control with client-side JavaScript just as
easily as you can with server-side C#.
<script type="text/javascript">
function enableButtons
{
document.getEle mentById('MyBut ton').disabled =
(parseInt(docum ent.getElementB yId('MyTextBox' ).value) == 0);
}
</script>
<input type="text" id="MyTextBox" onblur="enableB uttons();" />
<input type="button" id="MyButton" value="Save" />

great, thanks! I simply have lots to learn concerning JS. :-)
Since we're at this - assuming the following script-code ...
If Not ClientScript.Is ClientScriptBlo ckRegistered("E nableGo") Then
Dim strJS As String = _
"<script language=""Java Script""" & _
"function enableGo(chk) {" & _
"document.getEl ementById(""" & cmdGo.ClientID & """).disabl ed = " & _
"(document.getE lementById(chk) .checked == false);" & _
"}" & _
"</script>"
ClientScript.Re gisterClientScr iptBlock(Me.Get Type, "EnableGo", strJS)
End If
.... which is supposed to enable a button if the passed checkbox's ID
(ClientID) is checked. With controls that have been created at design-time,
this will work just fine (as with cmdGo.ClientID) , but in my case the
checkboxes are created dynamically.
Hence, I'm doing the following for each checkbox being created:
dim chkBox as New CheckBox
....
chkBox.Attribut es.Add("onclick ", "enableGo(" & chkBox.ClientID & ")")
However, instead of the ClientID, only the ID will be passed and the script
fails. Any clue on how to get this working for dynamic controls?
Cheers,
Olaf
