Untick checkboxes within a span of same name

Andy Green

I have a set of checkboxes (within a grid item template), and because of the way the page is I can't use a radio button.

I want to be able to only have ticked at a time.

So far I have added a class - chkPri.Attributes.Add("class", [String].Format("diags"))

and tried this jQuery - $('input.diags').not(this).prop('checked', false);

but the page is being rendered with the input inside a span with the class added to the span.

<span class="diags">

<input name="rpbOutcomes$i1$rgProcedures$ctl00$ctl07$chkPrimary" id="rpbOutcomes_i1_rgProcedures_ctl00_ctl07_chkPrimary" onclick="setDiags(this);" type="checkbox">


I have tried using inutAttribute but this wasn't being rendered.

I have also tried $("span[class='diags']").not(this).prop('checked', false); this finds the span but not the checkbox inside it.

Can anyone point me in the right direction.

Simply put I only want one checkbox to be ticked. The checkboxes are inside a grid.

Are these the only checkboxes on the whole page? Can you provide a rendered page in html code?


No I have 3 groups of checkboxes, its only these 1 set I want to control like this.

In the itemdatabound I'm adding the chkPri.Attributes.Add("class", [String].Format("diags")) so only this 1 set have the diag class attribute.

This is the html for the section:

Don't think is has copied everything  View source doesn't capure everything, this was taken from IE developer tools, but it too has missed some stuff.
