Set Edit box value with null value
Using SUP 2.2.
I have an MBO with a parameter defaulted value is <NULL>. So if this parameter is left alone, it would bring all the data back without any specific filter.
However, the parameter, as you might guess is coming from a drop down list which has static values. The MBO works well when the selected value from the list has a specific value. But I do have an option in the drop down with "All", which I need to some how set the drop down list with <NULL>. I've tried setting the field with empty quotation marks, with null and even <NULL>. But no data is returned. I am positive that the query does work and should have returned data, that I am very sure off.
So my question is, how can I set this drop down box with null value so that the MBO will work? Thanks.
