Working on a DragDrop application. I have a class object (built as an object) which has a GroupBox that is enabled for DragDrop.
In the class I have set it up so that the cursor will change when it enters the groupbox, leaves the groupbox, mouse is down within the groupbox and drag/drop is working. I also set up a label in the class object and changed the text in that label as well. Basically, the text changes in the label as expected including 'FEEDBACK' appearing when I am dragging the object BUT the cursor stays stubbornly as a pointer. This is tghe state of affairs either when I debug the class or when, after I build the class, it is run as part of the main program.
Here are the subs set up in the class.
Private Sub GroupBoxSourceMouseDown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GroupBoxSource.MouseDown
GroupBoxSource.DoDragDrop(GroupBoxSource.Text, DragDropEffects.Copy)

drag and drop - Change Cursor as Feedback in DragDrop
View 8 RepliesIn 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 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.

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

I'm trying to drag an item between two Groups in the same ListView called 'listTasks'.
Private Sub listTasks_ItemDrag(ByVal sender As Object, ByVal e As ItemDragEventArgs) Handles listTasks.ItemDrag
listTasks.DoDragDrop(listTasks.SelectedItems, DragDropEffects.Move)
End Sub
Private Sub listTasks_DragEnter(ByVal sender As Object, ByVal e As DragEventArgs) Handles listTasks.DragEnter
[Code]...
With listTasks.PointToClient(New Point(e.X, e.Y)) you could use listTasks.GetItemAt(p.X, p.Y) to get the ListView item you're over. Is there something like this for Groups? Or perhaps a better way to determine what group is the target of a drag-drop?
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.
