C# App: Question on .Net TabControl

[VigneshAnand]

Hi,
I am doing a small tool in .Net(C#). I have a TabControl in my application; I need to achieve two functionality in it as follows.

1. I have enabled drag-drop property for my tabcontrol, so what I want to achieve is when I drag an item and move over an tabpage name which is now currently not in front, has to come in front so that I can drop my item in that tabpage.

For example let’s say we have 2 tabpage named 'Tab1' and 'Tab2'. Right now Tab1 is in front so we can see only the items in Tab1 page. So now when I drag an item and move over Tab2 name I want to make Tab2 to come in front so that now I can see the items on Tab2 and drop items in that page.

2. My second functionality is to allow user to rename the tabpage name (Display text of tabpage). Is there any way to directly change the display text like file rename. Like some short-cut key F2 user should be able to change the text in the Tab control itself.

I can do it by popping up an dialog which takes the new display text and change the tabpage display text. Is there any better way to do this?


Thanks in Advance

1)
Drag-drop has some events that get fired, not sure if there any that help you. Check on the TabPages themselves (and not just the tabcontrol) to see if you can find something that will fire when dragging over a Tab name.
(Hot tracking is able to happen because some event gets fired when you mouseover the name, so SOMETHING has got to fire for it)

2) You could attack a keypress handler to the TabPage (not the tab control, although you could probably make do with that as well)
And watch for the F2 key. I would have it pop up a special rename dialog. Then you can just set the tabpage.Text to it.
Trying to directly edit the text on the top of the tab would be pretty crazy to implement (it would be a lot of keypress watching and owner-draw stuff)

Thanks Plater,
As per your idea on the second issue for renaming the tabname, I launched a dialog which takes the new name and updated the tabpage name.

But for the first issue drag-drop, none of the mouse events are getting trigged if i am dragging an item.

When i move the mouse without dragging any item all the events are getting trigged like MouseEnter, MouseLeave, MouseHover.

I am not aware of "Hot tracking" if possible can you please provide me some useful links on the same.

Thanks

Hottracking is a property on the tab control that changes the color of the tab the mouse is over, probably not useful.

There are "DragEnter" and the like events that should get fired for your dragdrop stuff?
