# Changelog ## [Unreleased] ### Tree Grid #### Features - `#I341079` - Provided support for exporting data to PDF, CSV, and Excel formats using server-side functionality. Please find the demo [here](https://ej2.syncfusion.com/aspnetcore/TreeGrid/ServerSideExporting#/material3). - Added support for the new `fixed` mode within the `freeze` property of column settings. When a column is set as `fixed`, it will stay within the viewport during horizontal scrolling, enhancing the user experience with improved visibility and efficiency. - Provided support for inline editing with virtualization enabled. Please find the demo [here](https://ej2.syncfusion.com/angular/demos/#/bootstrap5/treegrid/virtual-scrolling). - `#I323425`, `#I332700`, `#I344742`, `#I375307` - Provided support for frozen column with virtualization enabled. - `#F166825` - Provided support for infinite scrolling with observable binding. #### Breaking Changes - Optimized the frozen columns feature in Tree Grid and thus changed the dom structure of tree grid from two table to single table architecture. Also, the following methods have been removed, and it's recommended to use the following alternatives instead. | Removed methods | Suggested to use alternative methods | |----------|----------| | `getMoavableRows`, `getFrozenRightRows` | `getRows` | | `getMovableRowByIndex`, `getFrozenRowByIndex`, `getFrozenRightRowByIndex` | `getRowByIndex` | | `getMovableCellFromIndex`, `getFrozenRightCellFromIndex` | `getCellFromIndex` | | `getMovableDataRows`, `getFrozenRightDataRows`, `getFrozenDataRows` | `getDataRows` | | `getAllMovableDataRows`, `getAllFrozenDataRows`, `getAllFrozenRightDataRows` | `getAllDataRows` | | `getMovableColumnHeaderByIndex`, `getFrozenRightColumnHeaderByIndex`, `getFrozenLeftColumnHeaderByIndex` | `getColumnHeaderByIndex` | | `getFrozenRightHeader`, `getMovableHeader` | `getHeaderContent` | | `getFrozenRightRowsObject`, `getMovableRwsObject` | `getRowsObject` | | `getFrozenRightHeaderTbody`, `getMovableHeaderTbody`, `getFrozenHeaderTbody` | `getContent().querySelector(‘tbody’)` | | `getFrozenLeftContentTbody`, `getFrozenRightContentTbody`, `getMovableContentTbody` | `getHeaderContent().querySelector(‘tbody’)` | | `getFrozenRightContent`, `getMovableContent` | `getContent` | ## 20.2.36 (2022-06-30) ### Tree Grid #### Features - Provided support for inline editing with virtualization enabled.
