[ddincheva]

Description

• igniteui-angular version: 7.2.x
• browser: all

Steps to reproduce

• Can not navigate to root summary row when press Tab over the last cell in the grid's body - should be fixed with Including summary row cells in tab sequence for HierarchicalGrid navigation. #4293

• Error is thrown when click over summary cell and press Tab or Shift + Tab - should be fixed with Including summary row cells in tab sequence for HierarchicalGrid navigation. #4293

• When child grid is filterable and the focus is on the last filtering chip of that grid and press Tab the error is thrown in the console - should be fixed with Refactoring filter cell navigation so that it is handled in the navigation service.

Expected result

@ddincheva
1 - should be resolved with - #4221
3 - should re resolved with #4267

Regarding the summary below each grid, should it be part of the Tab sequence but not part of the Keyboard navigation with arrow keys?

[ddincheva]

Yes, the root summaries for the grid can be accessed only with tab, and can return from them to the grid's body with shift + tab. When we have a summaries on child level (when grouping is applied) the summary cells are part of the grid's body so they can be accessed with arrow keys. :)

@MayaKirova Also the first issue is still reproducible for the child grids in #4221 ; And the second issue is still reproducible in #4267 and in #4221 .. the errors are still thrown when I try to tab through summary cells
