I am loading data for child nodes from server side on expanding the row. I wanted to display the ‘ui-icon-radio-off’ icon for children at the last level, currently it is displaying downward triangle as I set loaded: true, expanded: true. Is it possible to change this icon to ‘ui-icon-radio-off’ as shown in the attachment below…
I suppose that the problem is the data which you used to fill the tree grid. The data should include the values of hidden columns. The column
isLeafdefines whether the row is a tree node or a leaf. The rows which hasisLeaf: truewill be displayed with ‘ui-icon-radio-off’ icon.You can find more details and example here, here, here or for example here.
