radiobuttonlist and javascript

[sramruttun]

hi
I have a checkbox and a radiobuttonlist (the radiobuttonlist contains 2
items) in my form. The radiobuttonlist has its visible property set to false
at design time. At run time, when the checkbox is checked, then I want the
radiobuttonlist to appear. I want to use javascript.

On Form_Load I've done:
chkM.Attributes .Add("onclick", "ShowPeriod ('" & RDLPeriod.Clien tId &
"');return false;")
The HTML Source:

<TR>
<TD>
<asp:Label id="Label8" runat="server"> Monthly</asp:Label>&nbsp ;
<asp:CheckBox id="chkM" runat="server" Width="81px"></asp:CheckBox>
</TD>
<TD colSpan="3">
<asp:Label id="Label9" runat="server"> Period</asp:Label>&nbsp ;
<asp:RadioButto nList id="RDLPeriod" runat="server"
RepeatDirection ="Horizontal " Visible="False" >
<asp:ListItem Value="All">All </asp:ListItem>
<asp:ListItem Value="Current Year">Current Year</asp:ListItem>
</asp:RadioButton List>
</TD>
</TR>
In the script section I have:
function ShowPeriod(w)
{
document.all(w) .visible=true;
//document.getEle mentById("RDLPe riod").style.vi sibility=true;
}

Upon execution, when I check the checkbox, the code breaks in the script
section and tells that :
'document.all(. ..)' is null or not an object

Where is problem guys ?

Setting the visible property of a server side object to False, means that
the HTML for it doesn't even get streamed down to the client. This is very
different from setting the "display:no ne" in the style of the object.

The problem is, the HTML for your radiobuttonlist never made it to the
client. This will be easy to check by chosing View -> Source from the menu
in IE.

Sam,

Attach the javascript at the same time you set the list to visible, and
remove it if the list's visiblity is reset to false.

chkM.Attributes .Remove("onclic k")

I hope this helps.
