View 2 RepliesI 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.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

how to drag an item on my Desktop to my Listview?
View 1 RepliesI already have one year experienced in c++, and built many private applications.My question is simple to ask, and simple to answer I think.When I select an item in a listview, I want the full item to be selected. Now only the TEXT in the listview item is selected. I've made a picture to clearify my problem.The picture in the link below is splitted up in two pictures. It shows what I currently have, and what I want (my aim)

View 13 RepliesI 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 working on a vb forms application in VS2008.What I am looking to do is have 3 file managers on the form.The top is the source where files can be copied to the 2 other file managers.What I have been looking for is an example of the file explorer so I can modify it.So far I have been unsuccessful in finding a good example so I am here to ask the experts.So the gist is the first file explorer will allow a user to connect to thier local hard drive.The other two file explorers would allow the user to connect to two different servers through entering the path they want to view those file trees.After that the user could click on the file they want to copy and then hit a button for example and the file would be copied from the local to the two other areas.Would it be easier to just use text boxes with a confirmation that the files are being copied?Or can a full file manager be built to drag and drop files?
View 2 RepliesOk, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

I have a form with a listview on it. Listviews are very versatile beasts with all kinds of odd options to them, so I'm not sure if this is working the only way that it can, or not. The issue is that when I select one of the items in the listview, only one column (of two) is highlighted. I'd prefer a selection appearance similar to using a DataGridView where the whole row is highlighted. Of course, one option would be just to switch to a DGV, but that would require a bit more code to get the column widths right. So my question is whether there is some setting to get what looks like full row selection appearance in a multiselect ListView?

View 1 RepliesI 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 have two (Telerik) TreeView controls, let's call them tvSource and tvDest. I want to drag/drop items from tvSource to tvDest. I have this somewhat working, but am experiencing two problems:
1) What it now does is moving the item. Instead I want them to be copied (from tvSource to tvDest), leaving the item in tvSource.
2) To allow items to be dragged from the tvSource control I have to enable DragDrop. With this enabled the user can drag/drop inside the tvSource control, which is not what I want. The items may only be dragged (copied) to an other control (tvDest).
Below is my code so far:
Private blnMouseIsDown As Boolean = False
Private Sub tvSource_MouseDown(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles tvSource.MouseDown

I am converting my company's VB6 program over to VB.net and I have hit another stupid little roadblock.
The old program had a ListView docked to the left side of the application screen. The user could place the cursor over the right portion of the ListView, the cursor would turn into the SizeWE arrows, then they could drag it, which would resize the ListView.
I am trying to recreate this. As far as I can tell there is no Property called "Resizable," or at least nothing is popping out to me. I do not believe that it is being done in the code.
Is there a property I am missing? If not, is there an easy way to do this within the code? (ie. is there a event that would make my life easier)
I am using Visual Studio 2008.
Edit: I see how how it was done in the previous program (you always seem to find it once you ask the question, don't you?). The old program had a invisible picture that was only a few pixels wide that when hovered over would change the cursor to SizeWE. You could then drag that invisible picture and that would hit an event that would then change the size of the ListView. This seems rather convoluted. My question still stands: Is there a better way to handle this dragging and resizing?
I have an MDI client, and I have a listview inside it. I want it to be kinda like a desktop feature. The problem is that whenever you open a MDI child and you drag it to the listview, it goes under it.
View 6 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?

How would i change the order the colums with drag and drop[code]...
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.

In WinXP with LV FullRowSelect enabled I can press and hold down the left mouse button and drag it down the right side of the left-most LV column and the rows are selected, but under Win7 I can only multiselect items with the mouse if FullRowSelect is set to false.
So I guess I need to write code to support this sort of feature for Win7 ? , and if true are there any code examples (I can't find anything) to save me some time?
