Current behavior 😯

According to docs (https://mui.com/components/data-grid/localization/#locale-text):
If you want to pass language translations directly to the grid without using createTheme and ThemeProvider, you can directly load the language translations from the @mui/x-data-grid or @mui/x-data-grid-pro package

However, in my project, setting up a datagrid like this:

import { DataGrid, skSKGrid } from '@material-ui/data-grid';

<DataGrid rows={rows} columns={columns} localeText={skSKGrid} />;

only takes effect for certain parts of the UI. I.e. the column options are properly localized:

wheras the footer in the table is not:

My code example is using v4 but just tested on v5.4.1 and the latest published on npm and same result experienced there. Either this seems like a bug or documentation is off.

Expected behavior 🤔

All keys passed to localeText take effect. Now only a subset does

Several things here:

The doc example is as follow:

import { DataGrid, skSK } from '@material-ui/data-grid';

<DataGrid rows={rows} columns={columns} localeText={skSK.components.MuiDataGrid.defaultProps.localeText} />;

skSKGrid should not be exported and has been removed in a release (you are probably using a v4 version before it)
skSK also includes the core translations (for instance the pagination "Row per page" is a core translation), that's probably why it was not translated in your exemple.

A working example with v5: https://codesandbox.io/s/datagrid-v5-quick-start-forked-vnevs

For V4, the logic is the same but the path differ skSK.props.MuiDataGrid.localeText

---

After that, if you have untranslated keys, it's because nobody translated them.
You can open a pull request to add correct translations and we will review it and add it to the next v5 release 👍
