How to remove null value legend values in pie chart in RDLC. I have set an expression in the visibility property.

=IIf(Fields!grp.Value = "", True, False)

But it is not working. But grp value is null in the dataset.

If you're actually dealing with null, you should try the following expression:

=IIf(IsNothing(Fields!grp.Value), True, False)

For an empty string you could also try this:

=IIf(Len(Fields!grp.Value) = 0, True, False)
