The script have to be fire on page load event...,
then call that script in body onload..,
either if u want to call that script during some event fire,
then do it in eventcontrol.attributes.add("event","function");

I have two functions.
function funEnableOrDisableTxtBox(objTextbox, objRadiobutton)
{
}
function funIsTextBoxEmpty()
{
}
I hv writn the follwong in page load
----
rbRndQRSSPoor.Attributes.Add("onClick", "funEnableOrDisableTxtBoxmstxtRndPoor1,rbRndQRSSPoor);")
btnSubmit.Attributes.Add("onClick", "return funIsTextBoxEmpty();")
---
Like this, I am calling this same function from other radio buttons click event also. If I comment this attributes.add, my page is loading well. But If I comment the body of the function, I am getting the error. Simply, I tried by giving the function name with out any body like mentioned above. Eventhough, I am getting Done with error. What to do? I think my problem is in attribute?

Look at above code.
You have missed "("
It should be
funEnableOrDisableTxt(BoxmstxtRndPoor1,rbRndQRSSPoor);

Problem is.........
I 've 4 radio buttons for Excellent, Good, Avg, Poor and one text box. If user select the poor, my txt box should be enabled and got focus. This is the requirement. So, I am calling this function for each radio buttons by passing arg.
rbRndQRSSPoor.Attributes.Add("onClick", "funEnableOrDisableTxtBox(mstxtRndPoor1,rbRndQRSSPoor);")
rbRndQRSSExc.Attributes.Add("onClick", "funEnableOrDisableTxtBox(mstxtRndPoor1,rbRndQRSSPoor);")
rbRndQRSSGood.Attributes.Add("onClick", "funEnableOrDisableTxtBox(mstxtRndPoor1,rbRndQRSSPoor);")
rbRndQRSSAvg.Attributes.Add("onClick", "funEnableOrDisableTxtBox(mstxtRndPoor1,rbRndQRSSPoor);")
function funEnableOrDisableTxtBox(objTextbox, objRadiobutton)
{
if (objRadiobutton.checked == true)
{
objTextbox.disabled = false;
objTextbox.focus()
}
else
{
objTextbox.disabled = true;
objTextbox.value = "";
}
}
on the above, I am passing the same args for all the dif radio buttons. Is not a proper way?.

Take RadioButtonList and call javascript onclick event and check Poor item is checked or not and make disabled true or false.
<asp:radiobuttonlist id="rbtn" runat="server" repeatdirection="horizontal" onclick="chk();" >
<asp:listitem text="Poor" value="0"></asp:listitem>
<asp:listitem text="Exc" value="1"></asp:listitem>
<asp:listitem text="Good" value="2"></asp:listitem>
<asp:listitem text="Avg" value="3"></asp:listitem>
</asp:radiobuttonlist>
<asp:textbox id="txt" runat="server" ></asp:textbox>
javascript function
function chk()
{
if(document.getElementById('rbtn_0').checked)
{
document.getElementById('txt').disabled=false;
document.getElementById('txt').focus();
}
else
{
document.getElementById('txt').disabled=true;
document.getElementById('txt').value='';
}
}

I highly doubt that was the error. Perhaps if you post the actual message, we can help more ?
Where does this function come from ?

'funEnableTxtBox' is not a member of ASP.frmBAFeedback. This is the actual error, I faced.
I have written my function in design page-source view of frmBAFeedback.aspx file
function funEnableTxtBox()
{
if(document.getElementById("rbRndQRSSPoor").checked==true)
{
var a;
a=document.getElementById("mstxtRndPoor1").value;
if (a == "")
{
alert("Please enter the reason for poor.");
document.getElementById("mstxtRndPoor1").focus()
return false;
}
}
}
I called this fun by other way (onClick event of radiobutton). It is working fine. But I need, "Is there any option to call this function when page loads?"

Set a breakpoint in that page init method, and see what's going wrong.

Exam certificacion question
Ive seen this question in more than one simulator with C,D and also B,D or even just B as answers, what do you think would be the correct one and why?
You create a Web Form. You need to add controls that use adaptive rendering to display content. The type of content rendered must depend on the device that is requesting the page. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
A. Add custom controls that emit XHTML to the Web Form.
B. Add custom controls that emit WML to the Web Form.
C. Add mobile controls to the Web Form.
D. Add Web server controls to the Web Form.
Answer: C, D
