How to check if SSRS Textbox is empty

Try the following:

=IIF(Len(ReportItems!txtCountVolunteer.Value) <= 0, true, false) 

You should use this expression

=IIF(IsNothing(Fields!UserEmail.Value) OR Fields!UserEmail.Value = "",
 "Empty", "Not Empty")

The first: IsNothing(Fields!UserEmail.Value) checks if the field value is NULL The second: Fields!UserEmail.Value = "" checks of the filed value is blank ""

So you need both of them in order to check if the value is either null or empty.

Try the IsNothing function like this:

IIF(IsNothing(ReportItems!txtCountVolunter.Value), "empty", "not empty")

Check for null

=IIF(IsNothing(ReportItems!txtCountVolunteer.Value),true, false) 

For those who come from a .NET world and you want to check non-empty and say for argument sake want the value 0 instead of blank!

=IIf(String.IsNullOrEmpty(ReportItems!txtCountVolunteer.Value), 0, ReportItems!txtCountVolunteer.Value)
