I am trying to implement a filter from a combobox with checkboxes enabled in order to create a where clause that would look a bit like
I create the combobox with checkbox option on during 'OnExpressionItemCreated', but am having trouble applying the selected values to the filter.
I have tried in 'OnExpressionEvaluated' to reformat the evaluationData ExpressionFormat and Value to produce what I am looking for to no avail. I have also tried in the same method to create a group expression as a series of 'ORs', but can't figure out how to get this group expression to replace the original 'RadFilterNonGroupExpression'.
Any ideas how I could achieve my goal?
