Visual Basic :: Drag Multiple Items From Listview To Treeview

Please Help Me With Drag-n-Drop Of Multiple Items From One Listview To Another.
Hello!

I'm facing a problem with Listview Drog and Drop of multiple items from one listview to another listview. When I try to Drag only one single item, the item is dragged without any problem. However, when the multiple selected items are dragged, the Listview on which the items are dropped, receives information about only one item and not all selected items. The item, about which the information is received, is the same on which I click and hold mouse to start drag action. So, it looks like even though multiple items are selected in a listview, while executing the Drag-Drop action, listview treats it as single item selected!

Is this a default behavior of Listview or am I missing/doing anything wrong? Any work-around for this (seems like default) behavior of Listview? I searched for it and got a code example at http://btmtz.mvps.org/listview/ where the author has demonstrated Drag-Drop of multiple items. However, the code is specifically restricted to re-arranging items within same Listview and the information is transported via Drag-Drop to another Listview, upon which the items are dropped.

To help you all to get a better insight of my problem, I have attached a Demo of Listview Drag-n-Drop. Please see the project and you will see that when one item is dragged from left side Listview to right side Listview, no problem for VB to allow me to do it! However, when you select multiple items in left side Listview and try dragging those to right side Listview, only one item is dragged. Please let me know if I'm doing anything wrong here and please help me to get this stuff to work!

Waiting for your valuable reply ...

Treeview/Listview Drag And Drop
Hello.

I have 2 questions about dragging into a listview:

1)
Where can I get the code for dragging a specific node from a treeview, into a listview (I just need to add the value of the dragged node as a new record in the listview).

2)
I also look for the code for dragging a file from the desktop into a listview. There are lots of exmaples on the internet for doing this, but I need to drag a file into a listview control (and not any other control).

Thanks,
Edi.

P.S.
I use VB6 and not .NET

LIstview && Treeview Drag And Drop Problems
Ok, I have two problems that I would really appreciate some help with. In my program I have a treeview, a listview and a webbrowser. When you expand a treeview node the Listview is populated with file paths like 'C:WindowsDesktopTest1.txt' etc. Now when I click those the webbrowser opens the file (using webbrowser1.navigate (the path)) and displays the text. Here's where I hit my problem.

I'm trying to drag the file path from the listview to a different node in the treeview, but whenever I put in listview1.drag vbbegindrag and set the listview's dragmode to be vbAutomatic I can't select a specific item. When I click anywhere in the listview it gives me the drag icon, but without selecting a filepath first i'm not dragging anything. Has anyone run into this problem before? I need to be able to click it and have it display the file and also be able to drag it to a new treeview node. Thanks in advance for any help.

Items In Listview And Treeview
HI

is there a way to add an item to listview and treeview without
first dimming an object of that type's item ?

when i add an item, one of the parameters is a "key" which is unique and help me to identify that item later on
but it doesnt work, i have to dim an item type
then add the item to the list/tree view and on that item add the subitems, or child items...

isnt there a way to add an item with a unique key so later on i can do whatever i want with it just by using that key?

Moving Multiple Listview Items Up Or Down At Once
Hi, does anybody know how to move multiple selected listview items up or down at once?

I found the subs below, but they only move one item up or down, even if I have selected multiple items.

Thanks.

vb Code:
Private Enum menmDirections MoveUp = 1 MoveDown = 2End Enum Private Sub MoveItem(ByVal penmDirection As menmDirections)Dim lvwItem As ListItemDim lvwNew As ListItemDim lvwSubItem As ListSubItemDim lngIndex As Long Set lvwItem = lstView.SelectedItem If Not (lvwItem Is Nothing) Then If penmDirection = MoveUp Then lngIndex = lvwItem.Index + 2 ElseIf penmDirection = MoveDown Then lngIndex = lvwItem.Index - 1 End If If lngIndex > 0 And lngIndex <= lstView.ListItems.Count + 1 Then Set lvwNew = lstView.ListItems.Add(lngIndex, , lvwItem.Text) For Each lvwSubItem In lvwItem.ListSubItems lvwNew.ListSubItems.Add , lvwSubItem.Key, lvwSubItem.Text, lvwSubItem.ReportIcon, lvwSubItem.ToolTipText Next lvwSubItem lvwNew.Selected = True Set lvwNew = Nothing lstView.ListItems.Remove lvwItem.Index End If Set lvwItem = Nothing End IfEnd Sub

vb Code:
Private Sub MoveUp(lv As ListView) Dim itm As ListItem, itmNew As ListItem, i As Long If lv.SelectedItem.Index > 1 Then Set itm = lv.SelectedItem Set itmNew = lv.ListItems.Add(itm.Index - 1, , itm.Text, itm.Icon, itm.SmallIcon) For i = 1 To itm.ListSubItems.Count With itm.ListSubItems(i) Call itmNew.ListSubItems.Add(, .Key, .Text, .ReportIcon, .ToolTipText) End With Next lv.ListItems.Remove itm.Index itmNew.Selected = True lv.SetFocus End IfEnd Sub Private Sub MoveDown(lv As ListView) Dim itm As ListItem, itmNew As ListItem, i As Long If lv.SelectedItem.Index < lv.ListItems.Count Then Set itm = lv.SelectedItem Set itmNew = lv.ListItems.Add(itm.Index + 2, , itm.Text, itm.Icon, itm.SmallIcon) For i = 1 To itm.ListSubItems.Count With itm.ListSubItems(i) Call itmNew.ListSubItems.Add(, .Key, .Text, .ReportIcon, .ToolTipText) End With Next lv.ListItems.Remove itm.Index itmNew.Selected = True lv.SetFocus End IfEnd Sub

Listview - DragDrop Multiple Items
I have the following code that successfully will drag & drop one item at a time, but doesn't work all the time if multiple rows are selected?
When I start to drag, sometimes nothing happens.

Anybody point me in the right direction please?

Code:
Private Sub lvwSelected_OLEDragDrop(Data As MSComctlLib.DataObject, Effect As Long, Button As Integer, Shift As Integer, x As Single, y As Single)
On Error GoTo ErrTrap

Dim i As Long
Dim lvwItem As ListItem

For i = 1 To lvwSource.ListItems.Count
If lvwSource.ListItems(i).Selected = True Then
Set lvwItem = lvwSelected.ListItems.Add(, , lvwSource.ListItems(i).Text)
lvwItem.SubItems(1) = lvwSource.ListItems(i).SubItems(1)
lvwItem.SubItems(2) = lvwSource.ListItems(i).SubItems(2)
'remove original item
lvwSource.ListItems.Remove i
End If
Next

Also, when dragging multiple items across, and removing the original item, I now get an error because the ListItem.Count is now out of bounds.
How would I handle this?
Would I add 1 to the value of 'i' before the next loop?

Multiple Selected Items In A Listview

Dragging Multiple Items From A Listview
i have some code to let users drag an item from a listview onto a treeview node, which works fine, but now i want to let them drag multiple items.

the problem is that when then select a bunch of items, then drag them to the treeview, it leaves only the last item they clicked on selected (as if they selected them, then just left-clicked one of them). is there a way to keep them all selected?

also, just out of interest, is there a way to make the drag icon include some text from each selected listview item along with an icon (like when you drag multiple files in windows explorer)?

thanks for any help

What am I missing?

Drag And Drop To Reorder Listbox Items??
All,

I am using VB6 with a standard listbox control. What I am trying to do is get drag and drop capability on the items within the list box so that users can re-order the items by dragging and dropping them to the new position.

I have found code on MSDN that works...sort of. It uses the DragDrop event that seems to set the DragMode to automatic in code. The drag and drop does work but it seems as an artifact of that, when I click and drag the item, rather than isolating to the selected item, the entire frame of the listbox becomes attached to the mouse cursor and is dragged as the mouse cursor is moved.

Additionally, it doesn't actually move the control, it just drags the frame with the mouse cursor, when the mouse button is released, the frame disappears and the item is rearranged in the list. I want to just have my defined cursor display, not the list box frame.

Anyone have any code or know how to easily rearrange list box items?

Thanks in advance,

-John

TreeView Drag Image
I have a project that uses a hierarchical TreeView to permit the user to navigate a file structure some three levels deep.

I used an ImageList to assign distinct icons for several file types.

Everything looks good, but when the user drags a file from the TreeView to the designated place, the system blows up the icon to large size as the drag image, and it looks blocky and messy.

I carefully designed the icons to have a 16x16, a 32x32 and a 44x44 representation within the .ico file, but it appears as if the system only uses the smaller image and expands it in crude fashion. It seems to handle stock icons from Windows nicely, but messes up the ones that I created.

Am I missing some trick?

[Edit: I just found this article. Maybe it's not my fault at all!]

Treeview And Drag&&Drop
Hi,

I have a treeview with an drag&drop function.
this treeview has 3 layers.

Code:
layer 1
+--layer 2
|--layer3
|--layer3
|--layer3
question:
how can the drag&drop functionality be restricted to the only case that the user is able to move an item from layer 3 into the layer 2 only without creating a new node?
All other layer combinations should be blocked!

Here is my code:

Excuse the crude looking code.

I am having trouble with a simplistic drag and drop within the treeview.

I have managed to implement the following code which works fine when selecting a node and highlighting a node to drop onto.

i)The node used for dragging is always the root node.
ii)It seems to drag the whole treeview control not the node I select.

Any help would be appreciated.
Thanx in Advance.

TreeView Drag Text
Hi,

I am having trouble with ms treeview, I currently have drag and drop working but want to have an image of the node text dragged to the new control. DragImage will only do a picture not the text which can change at run time so no good. I have looked at tvdragdrop.zip example and was confused, I don't want to move the nodes within the treeview either.

Any ideas as I cannot think of any

Thanks
