Filtering with functions

[FeliceR]

Hi,

I'm using Your grouping engine and I'm trying to filter the source with an expression like this

ColA ColB
A1 B1
A2 B2

Filter = Substring(ColB,2,1)="1" (extract from position 2 of ColB 1 char)

I have seen ExpressionFieldEvaluator but I can't get a result.

Do You have a sample for this filter operation, please?

Regards

Hi Felice,

Please refer to the following sample from our sample browser that demonstrates the filtering feature using grouping engine. It applies simple button handlers that can sort on a key, filter on a key, or add a summary. It also illustrates how to access information maintained by the grouping engine.
