Question

I am doing computations on that data that will result in #Error at times. The underlying cause is a divide by zero. I could jump through the necessary work arounds to avoid the divide by zero, but it might be simplier to mask the #Error text and show a blank cell. Is it possible to hide the #Error and just display nothing?

Edit

The expression for the text might display #Error is something along these lines:

Fields!Field1.Value / Fields!ValueThatMightBeZero.Value

I could work around this with some ugly checking, but it might be easier to just catch the #Error. (A straight iif check around the express doesn’t work because SSRS evaluates both the true and false clauses first; if it gets a divide by zero on either clause, it will return #Error, even if that clause wouldn’t have been used).

Answer 1

There is an IsError function, but it won’t reduce the code you need to handle this. If you don’t like the usual iif work arounds, then I think you need to use your own embedded code in the report. In that code you can have a try catch handler. Create a function that you can call with =Code.MyDivider(Fields!Field1.Value , Fields!ValueThatMightBeZero.Value)

Public Function MyDivider(top As Double, bottom As Double) As Double
    If top = 0 Then Return 0
    If bottom = 0 Then Return 0
    Return top / bottom
End Function
