DataGrid - 'selectedRowKeys' argument of the SelectionChanged event keeps keys of removed rows on assigning a new data source

created 2 days ago (modified 2 days ago)

Steps to reproduce:

  1. Run the sample: CodePen.
  2. Select the row with id=3.
  3. Click the "Remove id=3" button.
  4. Select any other row.
  5. Open the console.

Expected results:

The "Select All" checkbox is not checked. The console logs one row object

Current results:

The "Select All" checkbox is checked. The console logs two row objects but one is selected.

Additional information:

The issue occurs only if repaintChangesOnly is enabled.

Workaround

Set DataGrid.keyExpr and use the Push API to remove the row:

JavaScript
const list = myData.filter((item) => item.id !== 3); grid.option("dataSource", list); grid.getDataSource().store().push([{ type: 'remove', key: 3 }])
