  To add collapse and exapnd all buttons for the grid, you could use javascript like this: <button id="expandAll">Expand All</button> <button id="collapseAll">Collapse All</button> <script> function toggleRows(condition) { $('#TreeGrid1 .awe-ghead.awe-row').each((_, row) => { const isCollapsed = $(row).hasClass('awe-collapsed'); if (condition === 'expand' && isCollapsed || condition === 'collapse' && !isCollapsed) { $(row).find('.awe-ceb').click(); } }); } $(function(){ $('#expandAll').click(() => toggleRows('expand')); $('#collapseAll').click(() => toggleRows('collapse')); }); </script>
