I have a grid with in-cell editing. Only some of the columns are editable.
The grid is grouped by two columns, which I default in OnGridStateInit. The two aggregate columns are NOT editable.
Everything works just fine, but as I click around through the editable columns, the page gets slower and slower and slower over time. Specifically, clicking away from an editable column causes a refresh (or something) that takes increasing longer and longer. A spinny loader appears.
This behavior immediately goes away when the grouped columns are removed by ungrouping at the top of the grid (no code update).
Is this a bug or am I doing something wrong?
I tried changing from in-cell editing to in-row editing and have the same problem.
A workaround is to ungroup for editing, and then regroup for display purposes, but I'm new and want to verify I'm not doing something wrong.
