Hi Telerik supporters,

In the progress of implementing my task, I met a strange behavior in Telerik Radlistbox control.

I have a Radlistbox with 5 items:

Item1

Item2

Item3

Item4

Item5

Select the first three items (item1, item2, item3); drag these three items and drop at the position after item5 (separator points at end of list box).

Nothing happens meanwhile it should be:

Item4

Item5

Item1

Item2

Item3

This occurs for a range of items which is equal or greater than 3. The list box reordering works fine while dropping with only one item.

Is there a work around solution? Any advice are all appreciated.

Thanks and regards,

PhuongTo
