Description

Please consider the following scenario:

  • fill a grid
  • group the data by dropping a column header in the drop panel
  • expand one or more groups
  • sort a column: this causes all expanded groups to collapse
  • expand one or more groups
  • resize the grid

The last action causes all expanded groups to collapse. If the grid is sorted before the grouping is applied the behaviour does not occur.

Research direction

Reproduce the issue in the grid by grouping data, sorting a column, expanding groups, and then resizing. Trace the grouping, sorting, and resize paths to determine why expanded state is lost; done means expanded groups remain expanded after resizing in the described sorted-and-grouped scenario.
