I have a simple function which tries to get a value from an Obout grid filter column, and if the value is empty, ignores it and moves on. For some reason this code ignore my catch block and always shows a System.FormatException when the input string is empty!
More bizarre, if I use visual studio's debugger and set a breakpoint on that line, the catch block functions normally (after I continue from that line). I have already confirmed that my Debug | Exceptions | CLR are not set to catch when thrown. I have also confirmed this same behavior in the production version.
'Get the month selected
Dim MonthSelected As Integer
MonthSelected = CInt(DateCreatedColumn.FilterCriteria.Value)
Catch ex As Exception
'If value is empty / not a number reset the filter
DateCreatedColumn.FilterCriteria.FilterExpression = String.Empty
