Why do you want to check it? If it is to replace it with something else, then you should use the ItemDataBound event.

because suppose the records could be like this

manager: zzz
phone: 55555

or
manager: GGG
phone:

so i don't want if the phone is not entered in database the word "phone" be displayed also. so i think i should check the value of phone field if is not bull so i do the rest.

OK, in this case you should create a label with a Text property of "Phone". Then, in the ItemDataBound event, check if the field is Null and if it is set the Label's Visible property to False.

now i have used Repeater, do u mean i can not do it by using Repeater, i should do that by what?
sorry i am not as professional as you, so i just get confused about ItemDataBound?

Thanks

Yes you can still use the Repeater - the ItemDataBound event is an event that is raised by the Repeater when an Item is bound.
