Enable checkbox for single selection mode in TreeView component
1 min read
The single selection on TreeView nodes along with the checkbox can be achieved by unchecking the previously checked nodes using uncheckAll methods during the nodeChecking event.
Refer to the following code snippet.
var treeObj = new ej.navigations.TreeView({
nodeChecking: function(args) {
if (args.action === 'check' && args.isInteracted) {
treeObj.uncheckAll(treeObj.checkedNodes);
}
}});
treeObj.appendTo('#tree');
