Hidden Expression for Group Header

I am trying to hide a group header (table row) based on the value of that group, but have not been able to get it working.

Let's say I have 2 groups in my table:

Group 1: State

Group 2: City

I want to hide the group header (tablerow2) where State = "Unknown" but I want the Group 2 cities to still display - just w/o a header.

I tried putting the following expressions on the hidden property of tablerow2 with no luck:

First I tried referencing the field that it's grouped on:

=Iif((Fields!state.Value = "Unknown", true, false)

I also tried refereing the name of the group:

=Iif(("State_GRP" = "Unknown"), true, false)

In both cases, nothing gets hidden - all rows, including the group header that says "Unknown", are visible.

Any help would be greatly appreciated!

You are doing this correctly, and I was not able to reporduce the behavior--it works as you are thinking. I would make sure that the case of "Unknown" is consistent with the field value. I would do this in the expression (or change the query to do the trimming), so that case and extranious white space is not a factor.

=IIF(Fields!state.Value.Trim().ToLower()="unknown", true, false)

|||Thanks Ian - the trim/tolower seemed to resolve whatever issue I was having.
