I can't create a DataGrid record

I’m following the example to create and edit online records within the DataGrid, apparently everything works fine, but by clicking on the Ok button the registration does not persist. What am I doing wrong?

Hi,

If you’re talking about this sample, then it doesn’t provide commit logic, since we don’t want data to be saved.

You need to add EditorPostCommitListener and commit datasource, for instance:

ctlPaisTable.addEditorPostCommitListener(event -> ctlPaisCollectionDs.commit());
