Client Side Checkbox Code

[Guest]

I have a checkbox on a web page. When it is checked, I want a Table to appear (or disappear when the checkbox is cleared)... I was hoping to use client side code for this, so I created a short vbscript routine and added this to my code behind module:

chkRecur.Attributes.Add("onchange", "vbscript: ShowRecurringTable")

Now, this works just fine on a couple of textboxes that I'm using, but when I try this technique with the asp checkbox, the "onchange" attribute gets added to a <span> element before the <input> element when rendered...

Can someone explain why this is happening? Can someone explain a simple way to accomplish this with an ASP checkbox server control, without requiring a trip back to the server? Thanks.

<Span> should not be an issue. Is it not working that way? I often add
my OnChange events into span blocks.

The code never runs when the checkbox is clicked... I ended up using the
server side event.

Hi Jerry,

The ASP.NET CheckBox control is a customized one compared to the raw html
<input type=checkbox....> element. So it use a <span> to wrapper the <input
type=checkbox> and a <label> (normal html checkbox dosn't have text
.......). Thus, all the serverside attributes we apply on the asp.net
checkbox control will appear in the <span> element..... As for this
problem, I used to use the "onclick" event instead since each time the
"onclick" event occur, the checkbox's <span> will also notify its child
element and cause the <input checkbox> also change status.... You can have
a try on this to see whether it helps.

Thanks,
