I am trying to figure out a way to include the listview's tag field when dragging one listview's subitems into another listview. I am hoping someone here has experience with this. My Listview drag code is below - the two listviews that I am dragging subitems into or from are LV1 and LV3. Also, this is being done in Visual Basic 2008 and the project is a windows application.

Can it be drap and drop item to other form control??How to write the event when mouse up at the other form control?
I am trying to implement a drag and drop operation in a listview (the listview is set for Details). The idea is to be able to allow the user to select one or more items and then "move" them elsewhere in the list.and modified it some because that example does the operation between two listviews, and here I am trying to do everything in the same one.Here's the code as I have it:
Private Sub ListView1_ItemDrag(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag
Dim myItem As ListViewItem
[code].....
In the attached program, I have 3 listviews.
1 is Source Invoices
2 and 3 is Customers.
When I drag something from ListView1 - it stays there, and turns a different color to show it has already been assigned. It stays in the list. This is what I want. When I drag something between 2 and 3, it should delete from the source and clone to the destination. It does this when I move 1 at a time, but if I select multiples (try 5 records) it does 3 of them, then the source list gets an error:
System.NullReferenceException: Object reference not set to an instance of an object.
If I highlight all 5 items in list 2 or 3 - then select the top item as the item to drag across, it seems to work.
If I highlight all 5 items in list 2 or 3 - then select the middle item as the item to drag across, it seems to NOT work.
I have tried going from top of list to bottom. Then thought, since I am deleting rows, maybe I should start at bottom and work up. Same thing?
I am trying to set up a listview where I can reorder the items, but no matter what I do the item i drag and drop goes to the end of the listview. I searched and tried to fix this issue but I just can't seem to find a fix.

View 1 RepliesThis is a little diffrent from your standard drag and drop, but I am trying to find out a way to support drag and drop, from a list control, which is displaying a list of files, held as "blobs" in a SQL database (compressed data in my own format). When the form is opened, I obtain a list of all the file names within that given table in the database, and display it to the user in the list view control. The user then has the option of dragging that ListItem from the ListView on to the dektop (or other directory location). Upon doing so, I need to be able to read the data from SQL, decompress the data (in my own format) and then save it as a file at the dropped location.
My main problem is detecting when the ListItem is dropped outside of my application, as I want to use this dropping event to trigger the code in to obtaining a copy of that file from the database, and save it in to the "dropped" directory, where ever that may be.
So Im mainly looking in to how I can "see" the final location where the item is dropped, and how I can start off the drag and drop operation in the first place with no initial data (since I have not obtained the file at the start of the operation). Getting the file at the start of the drag and drop operation intoduces "lag" while the application makes the trip to the SQL database (via web service) and obtains the data, so I need to carry out that trip to the database, at the end, while still allowing "Windows" to act as if I am dragging and dropping a file...
I did consider multi-theading, and downloaind the file from the database while the drag and drop operation is in progress, but then it becomes a race between the data being obtained from the database, and the user dropping the file.
Im using VS2005, SQL 2005 where the file is stored as a blog. SQL is on another PC running a web service which I interact with, to allow my application to talk to the database over both a LAN and WiFi via the internet. Compression and de-compression is handed at the client side application (for the file itself, in order to reduce the footprint created by the internet traffic) , where the user interface is displayed.

drag and drop nodes within the same tree (not between trees) when users drag and drop nodes within the tree, give them the option to move the original node to a new location within the tree OR to just copy the original node in a new location (seems complex but I have a month to figure this out). change the system default blue highlight for selected nodes to another color change the system default cursors for invalid and valid drops (instead of the circle with slash indicating invalid target, i want a red minus) and (instead of the little plus sign with little box indicating a valid target, i want just a big green plus sign) add a red insert line to indicate where the node would be dropped within a tree also drag and drop the text of a node from the tree to a textbox add a "folder" image next to parent nodes and a "document" image next to children nodes

I want to be able to hold CTRL down to select multiple text entries and drag them all to certain text boxes. Or even one at a time, but once I try dragging another word into the box it replace the first one. Is there any way to just have it add to the text box rather than replace it?
And if possible, place a "-" between each entry?
This is the pop-up form with the listbox that contains the words to drag:

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.

I've seen the code on this site to setup a drag-and-drop between 2 listboxes (and that works perfectly for me), but I have a need to be able to move items between up to 12 listboxes. For example, I move an item from listbox1 to listbox2; at some point in the future, I need to be able to move that same item from listbox2 to listbox3, then at another point in time from listbox3 back to listbox1, etc. When I make these moves, I need the item to be removed from its previous location. I've attempted to modify the 2-listbox code to include, on my test form, a third listbox, but that code copies to the third listbox, and when I attempt to move the item from the third listbox to the second, it, too, only copies and does not remove the item from listbox3.
