Run JavaScript code at ASP.NET page load
- by vaibhav
I have a radiobox <asp:RadioButtonList CssClass="list" Style="width: 150px"
ID="rdo_RSD_ExcerciseRoT" runat="server"
Font-Bold="false" RepeatDirection="Horizontal" RepeatLayout="Table"
TextAlign="Left" >
<asp:ListItem Text="Yes" onclick="en();" Value="Y"></asp:ListItem>
<asp:ListItem Text="No" onclick="dis();" Value="N" Selected="True"></asp:ListItem>
</asp:RadioButtonList>
AS you may see second listitem is selected by default. But issue is, when my page is getting load dis() is not getting called. I want to run dis() on page load too.
I tried google, some blogs suggest the use of Page.RegisterStartupScript Method. But I dont exactly know what is the problem and why we should use this above mentioned method. I would appreciate if someone please tell me why this function is not getting called and how to call it.
Edit: I am giving Javascript code also, if it helps.
<script type="text/javascript">
function dis()
{
ValidatorEnable(document.getElementById('<%=RequiredFieldValidator32.ClientID%>'), false);
}
function en()
{
ValidatorEnable(document.getElementById('<%=RequiredFieldValidator32.ClientID%>'), true);
}
</script>
