Either check
if (query.Length > 0)orif (query != string.Empty). If yourqueryvariable can benullthen you can checkif(query != null). Good luck! :) so your statement should read:if (query != null)
{
if (query.Length > 0)
//permission granted

Thanx.. its actually very silly doubt... the logic dint strike me as im a new comer in programming... Thanx alot.. regards, tash
to check if a string is null or empty, usually
if(!String.IsNullOrEmpty(value))should be used. This checks for both empty and null strings. -

{
permission granted
}if (!string.IsNullOrEmpty(query))
{
// premission granted
