SSRS - Hide table/column headers if there are no rows after applying the a hide row expression. Or another way perhaps
In an SSRS report I want to hide the tablix/table when there are no rows appearing. Problem is there are rows, but I hide the rows when column 1 is the same as column2. So my problem is that I don't want the column headers / table to appear when no other row appears. Is this possible I think there are scope issues doing this.
At moment I have two datasets. One retrieves current values, the other dataset retrieves historical data from a specific point in time. So I am using the lookup value '=Lookup(Fields!LabelLookup.Value, Fields!LabelLookup.Value, Fields!Value.Value,"Date2")' to show in one cell what the value was at a specific date and in the other cell what is is now on the same row. When the two values are the same I hide the row because there was no change. This works fine, but sometimes I am left with just the table header showing no rows. However, there might be lots of rows but are actually duplicate, as the value has not changed between the two dates.
Is there a way to check if there are no rows appearing in the table after the hide rows has been applied? I'm not sure it is possible? If not is there another way I might be able to do this?
