Hi Rikam,

We’ve reviewed the case with our team, and a few questions came up regarding the reasoning behind the need for editing functionality in this component. Generally, the ListBox is not designed with editing in mind—it’s more suited for selection and transfer operations. For scenarios that involve editing and reordering, the Grid component with drag-and-drop enabled might be a more appropriate fit. Would using the Grid work for your use case, or is the ListBox still your preferred choice?

That said, it's currently possible to implement editing in the ListBox using the ItemTemplate. This provides flexibility to add custom update logic per item—for example, showing a textbox when an "Edit" button is clicked, then hiding it once the edit is complete. Given this capability, it’s worth considering whether a built-in editing feature would truly add value or simply increase the component's complexity.

We’d appreciate your thoughts on this. Let us know what would work best for your scenario.

Regards,
