Hi,

Below is the Javascript function that am trying to call from asp:Button
control.

<script language="javascript">
function ValidateDate(fromDate,toDate)
{

var fromDate=new Date();
var toDate=new Date();
var diffDate = Math.round( ( toDate-fromDate ) / 864e5 );
alert(diffDate);
if( diffDate < 0 )
{
alert( "The start date cannot be after the end date!")
return false;
}

if( diffDate > 30 )
{
alert( "Please enter dates less than 31 days apart" )
return false;
}

return true; //allow submit
}
</script>


In code-behind am calling the function like as below:
btnSubmit.Attributes.Add("onClick"," return ValidateDate(" +
txtFromDate.Text.ToString() + "," + txtToDate.Text.ToString() + ");");



But if start entering the dates,it submits the page as it takes both
datee as current dates.Please let me know the reason.

Thanks,
Vishnu
