Get Data Index in the ListBox after Reordering
|Product||ListBox for Progress Kendo UI|
|Operating System||Windows 10 64bit|
|Browser||IE For PC|
Can I easily retrieve the index of each data item after reordering the ListBox?
The ListBox does not provide a built-in solution for achieving this behavior. However, you can still work around this issue by applying custom logic on the
reorder event of the ListBox.
The Kendo UI dataSource features the
indexOf method but the data items are not automatically reordered in the dataSource after the reordering takes place. To retrieve the index of a specific ListBox data item, manually remove the item from its current and insert it in its desired position. When the indexes of the dataSource items match the order in the ListBox, then the
indexOf method returns the correct index.
For a working demo, refer to this example. Although the demo uses the jQuery version, the logic applies client-side methods and the implementation for the AngularJS version is similar.
