I have a grid with 2 fields that are connected so a cascade filter needs to be done on them. I manage to do this using Server binding because the UI was refreshed when a filter was done. But now I have to use Ajax binding but the cascade code does not work anymore because the UI is no longer called again
1. in subFilter is there a way to get to the grid datasource without using the grid id? I need to make this code be used by any grid that has a dependent list
2. for the Ajax-binding I was thinking to use the onFiltering event but how can I get to the filter control (to do the subFilter code)? On a page with 2 grids and the same dependent cascade filters I could not find a connection between the grid and the filter controls.
