Data Grid

Breaking changes

• The columns management component has been redesigned and the component was extracted from the ColumnsPanel which now only serves as a wrapper to display the component above the headers as a panel. As a result, a new slot columnsManagement and the related prop slotProps.columnsManagement have been introduced. The props corresponding to the columns management component which were previously passed to the prop slotProps.columnsPanel should now be passed to slotProps.columnsManagement. slotProps.columnsPanel could still be used to override props corresponding to the Panel component used in ColumnsPanel which uses Popper component under the hood.

   <DataGrid
    slotProps={{
  -   columnsPanel: {
  +   columnsManagement: {
        sort: 'asc',
        autoFocusSearchField: false,
      },
    }}
   />
  

• Show all and Hide all buttons in the ColumnsPanel have been combined into one Show/Hide All toggle in the new columns management component. The related props disableShowAllButton and disableHideAllButton have been replaced with a new prop disableShowHideToggle.

   <DataGrid
  -  disableShowAllButton
  -  disableHideAllButton
  +  disableShowHideToggle
   />
