[RESOLVED] firing javascript on OnCheckChanged radiobutton event

I have some javascript that I'm trying to fire off when the checked status of a radiobutton is changed. its suppose to uncheck any checkboxes that are checked on my page. the checkboxes are named CheckBox1, CheckBox2, etc. Here is my javascript

Code:

---

        <script type = "text/javascript">
        function uncheckAll()
                        {
                                for (var j = 1; j <= 14; j++)
                                {
                                        box = eval("document.Form1.CheckBox" + j);
                                        if (box.checked == true) box.checked = false;
                                }
                        }
      </script>

---

and here is my code in my html:

Code:

---

<asp:RadioButton id="OptionButton3"  OnCheckedChanged="uncheckAll()" runat="server" Text="CONCENTRIC OR COMPRESSED" GroupName="CableType"></asp:RadioButton>

---

But when I load the page i get this error:


Compiler Error Message: BC30456: 'uncheckAll' is not a member of 'ASP._500_10_aspx'.


I'm coding in VS.net. Why can't it recognize it?
Thank you!

You cannot execute client side script by using a tag within a server side object.

Therefore, make the radio button like this:
<asp:RadioButton id="OptionButton3" runat="server" Text="CONCENTRIC OR COMPRESSED" GroupName="CableType"></asp:RadioButton>

Then, in the Page_Load event, do the following Response.Write:
Response.Write("<sc" + "ript lang=\"javascript\" for=\"" + OptionButton2.clientID + "\" event=\"OnCheckChanged\">uncheckAll()</sc" + "ript>");

Well I changed the OnCheckChanged event to OnClick (even though VS.NET doesn't like it and underlines it) and it worked perfectly.

Which is better?

OnClick working for you, provided it continues, is a fluke.

If it is, indeed, working, then ignore the underline and keep going.

For future reference, make sure the code above is easily accessable for you.

Thanks again! I'll be back soon with more questions I'm sure.

Thanks for eveything!
