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

I want to drag and drop avi files to a listview for burning from a OpenFileDialog box. I have used most of the code on here and nothing works. I am using VS 2008 Pro, OS is Vista. If there is any code out there, could someone Please point me in the right direction.

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 have been able to implement drag and drop successfully on my listView object if you were to drop a file on it, however I seem to be having some troubles if the user were to drag the folder onto the object. Is there a simple way to check if the user dropped a folder, and if so, list all of the files in the folder/subfolders?
View 6 RepliesI'm working on a small utility program and found that I have a need to copy the contents of listboxes, textboxes and other control from one to another.
I just started playing around with Drag and Drop but it seems lacking a bit...for instance, if I wanted to drag the contents of a listview to a text box, it doesn't look like I can do that easily if at all.
Can you use a drag and drop to copy the contents of different control types easily?I thought about using the drag and drop method for notification of the intent to copy the contents and then I would code the copying.
The idea (although I know it will be slow but that is okay for this utility) to copy the source to a textbox and then from the textbox to the target. The content won't be that large and speed is not a concern at this point.
Here is my issue if I have to do it this way.
1 - How can I use the control names to do this?
2 - How do I get the target control name?
I figured I would create a function that I would pass the source control name and the target control name and based on type, perform the appropriate method of copying the data.
I haven't figured out a way to get the target control name. I can use activecontrol.name for the source.

vb 2008 compared to 2003 is the ability to drag controls onto the web form and place them where I want.With 2008, the form places the control to the left and I have to tab, space, set-up tables or similar techniques to get the control exactly where i want it. Is there a way to make the web form in 2008 work like the one in 2003?Other then this one oversight, I enjoy all other aspects of vb 2008.
