I'm having a surprisingly hard time finding this. I need to link a combobox to a datagrid, and that datagrid to another datagrid, so that, when one upstream gets changed, the two downstream change so show selected data.
I can sort of figure out how to do the combobox to the datagrid, but don't know if what I'd do would be best practice, or if there is a slicker way to do it. I can't find how to get the key field value from a datagrid record though, so that I can use it to set the filter for the linked datagrid. TIA.
