Hi ,

try this
add one label into your webform aspx page and assign the message to that label in your code behind

var invoiceInfo = from invoice in InvoiceData
if(invoice.ReceivedAmount>invoice.TotalAmount)
Labelmsg.Text= "You Have Entered More Amount Than Invoice Amount";
else
select new InvoiceMaster
{
InvoiceId = invoice.InvoiceId,
InvoiceNumber = invoice.InvoiceNumber,
InvoiceDate = invoice.InvoiceDate,
TotalAmount = invoice.TotalAmount,
ReceivedAmount = invoice.ReceivedAmount

}
