Drag And Drop From Datagrid To Desktop?

May 31, 2012

Is it possible to (without a mile of code) Drag and drop files from a datagrid to the desktop or open folder?

I have tried this:

Dim sFile As String = "D: est.pdf"
C1Grid_Documents.DoDragDrop(New DataObject(DataFormats.FileDrop, sFile), DragDropEffects.Copy)

But no file is created.

Drag And Drop On A Desktop Shortcut Icon?

Jun 1, 2011

I found this thread[url]...

and I have encountered the exact same problem, that the desktop shortcut icon created by the Setup program does not work when dragging and dropping a file (in this case an Access-database) onto it,

while a shortcut manually created works just fine.

I do not understand the answer in the above thread. But, anyway I would like to find a way to solve the problem directly, preferably through the Setup program itself.

Drag And Drop From ListView Control, To Shell (Desktop)

May 20, 2009

This 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/Drop Within A Tree And Drag/drop From Tree To Textbox

Oct 20, 2010

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 looked through the internet but I am having difficulty sorting through all the information available (I see a lot of information for Visual Basic 5 and 6, and those codes don't work for me in visual studio 2008). I can email anyone my code I have so far.

Public Class Form1
Private MouseIsDown As Boolean = False

Can't Drag And Drop Right

Jun 23, 2009

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:

Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown
ListBox1.DoDragDrop(ListBox1.SelectedItem, DragDropEffects.Copy)

VB Drag And Drop From LB To DGV

Sep 9, 2009

I am writing a small program that has two list box's which are populated from my sql database. I want to drag an item from LB1 to column1 in a datagridview and drag an item from LB2 to column2 in the same datagridview.

I am getting close, but I am having trouble getting the data to drop. I did some testing and I can drop a string, but I am not able to get the string data from my listbox. I just get a datarowview. I see the string inside the "itemarray", but cannot get to it.

Here is my dodragdrop:

LB_OriginalPallets.DoDragDrop(LB_OriginalPallets.SelectedItems(indexOfOldPalletToDrag), DragDropEffects.Copy)

Drag And Drop Across The Screen

Jan 23, 2010

I am very new to Visual Basic, but I am trying to build a simple program, and how to create a drag and drop that works, but I can't seem to figure out how to change the display as I drag across the screen. Basically, right now I have a circle with a line through it that goes across my screen as I drag and what I would like is for it to be the text that I am dragging that drags across the screen, just like a file on my desktop would do when I grab it and try to drag it somewhere else on the desktop. I have put my code in below, how to get rid of the circle with the line through it, and replace it with the actually text that I am trying to drag. I am using Visual Basic 2010

Public Class frmDragDrop
Private Sub labelMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles lbdragfrom.MouseDown
lbdragfrom.DoDragDrop(lbdragfrom.Text, DragDropEffects.Copy)

Drag And Drop Between More Than 2 Listboxes

Jan 8, 2010

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.
