but it not working properly

Both should work

ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "<script language='Javascript'> alert('" + Message + "'); </script>", false);

ScriptManager.RegisterStartupScript(this, this.GetType(), "key", " alert('" + Message + "'); ", true);

here problem is not with sendPopupMessage()

actully after 1st validation it doesn't get submit

Better way you use validators..

But see for more details

Validation controls, which includes theBaseCompareValidator,BaseValidator,CompareValidator,CustomValidator,RangeValidator,RegularExpressionValidator,RequiredFieldValidator, andValidationSummary control are not compatible with UpdatePanel

See it here

You can downlaod compatible ersion of validators from here
