[DataGrid] Fix singleSelect clearing to use empty string instead of null#22881
Merged
Conversation
…null Pressing Delete/Backspace on a singleSelect cell was setting the value to null, which caused MUI Select to warn about an out-of-range value. The correct empty value for a Select is '' (empty string), consistent with how row editing mode already handles the clear case. Fixes mui#22842 Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
