The reordering feature is one of the basic functions provided by Kettic tab control, through which you can easily change the existing order by dragging a certain tab or several tabs. But before you get to this, there are two things you should know first.

One thing you should bear in mind, is that users can only drag and reorder a certain tab within its child list level which they are currently in, and you cannot not drag it to an upper level, such as its parent tab. Another important thing you should remember is that when you drag to reorder a root tab, or a child tab with its own child tabs, all the children tabs will tag along with it.

So how do you order a tab control with simple drag and drop? Follow the steps below and you will see.

1. To begin with, you need to integrate a tab control into your ASP.NET web application first.
2. Then you can create any number of tabs as you wish.
3. After that you can customize the tab properties such as Text, Value, Tooltip, etc.
4. Or you can populate your tabs by data binding to data sources such as Array, DataTable, etc.
5. Finally you can drag any item in your tab and drop to a target location.
6. Please note that the drag-to-reorder feature can be applied both vertical and horizontal tab.

In the above sections, we have illustrated how you can easily rearrange the tab control order with easy drag and drop. In this section, we will introduce to you several sever side and client side events related to this reordering feature.

There is only one server side event related for this dragging & reordering feature, and that is the Reordered event. Note that this event only occurs whenever the tabs within your tab control are reordered.

Apart from that, there are three client side events related to the reordering feature, the DragStart event, Reordering event and the Reordered event. The DragStart event is fired right before the drag-to-reorder takes place. The Reordering event is fired between the start and completion of the reordering. That is to say, this event is fired after the dragging takes place and before it is completed. The last one - Reordered event, is only fired after the reodering is finished.
