Hi,
I would like to create one matrix with 2 headers. Its similar to system forms for example store items where on pane Stock is in matrix disponibilty for each stores and bellow is sum for all stores.
I read somewhere thats this are 2 matrixes - first standard and seccond only with header, but I cannot achieve the functionality as in system form when I change the width of one how to change the seccond because there is no event raised.
thanks for help
Petr
