VS 2008 Drag/Drop Between Two DataBound DataGridViews?
Mar 19, 2010
I have an MDI application that shows MDI forms with a single DataGridView on each form. The grid is bound to a List(Of Item), where Item is some class. Now I need to be able to drag (possibly multiple) items from one grid (in one form) to another grid (in another form).
Unfortunately, I know nothing about DataGridViews and even less about drag and drop, so this is turning into a real pain for me...I have been looking at examples for ages, but none of them work for me. Most of them don't deal with databound items, others don't seem to work at all, and yet others can only deal with a single row at a time (pretty useless for me).
This must be something that people need a lot, so I can't understand why the examples are so 'bad'.

I think I already know the answer to this, but I figured it would not hurt to ask.
Is there any possible way to nest Databound DataGridViews in .NET? What I would like to have happen is for each row in the DataGridView to have a button to expand, which would then give me a DataGridView underneath that. I would like this nested DataGridView to also be able to do this, so I could go n levels deep with them.
Is this possible with the .NET Winforms standard DataGridView? (Or another standard .NET control?) I have seen people reference some third party controls, however they are really expensive, and I don't really want to go that route.

i have a datagridview on my winform that is bound on the click of a node in a tree this is the binding code...
Dim myDocList As IList(Of DocumentTemplate)
myDocList = CorrespondenceHelper.GetDocumentTemplateByCorrespondenceId(Convert.ToInt32(e.Node.Name.ToString()))
'add new blank row at bottom
myDocList.Add(New DocumentTemplate())
[code].....
i added a blank row in because if i bound without it then i was unable to add new row.
AllowUserToAddRows = True is set also
but when i populate the blank row and tab of it i would like another blank row to be created below but unsure where/how i go about this?basically im aiming for teh user to be able to edit or add numerous records to the datagridview then commit all changes on one click (Save) at the end.

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 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?

I'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.

I am trying to implement a DnD interface where the user drags a button onto a DGV & a new row would be inserted at the drop point. My first problem is how can I have the DGV rows highlight as the cursor is dragged over them? And then I need to get the row index when the mouse button is released so that I can insert a row at that point?

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.

I am using Excel 2007, VS2008 Pro.I am building a VSTO Add-in that requires "drag and drop from Excel cells to a drag-enabled task pane".So far I notice that I can only drag and drop within the cells themselves. It does not allow me to drop into the task Pane or drag past the sheet limits.(http:)[url]...
Note: The task pane has drag drop enabled, I ahve already tested I can drag/drop from task pane to excel but I need to do this the other way around?

I have a form with 2 pictureboxes. 1 is for the canvas and the other is for holding about a dozen images (about 60x60 pixels each), pretty much icons. I would like to drag the images to the canvas and be able to move them around or delete them if necessary. Like setting up a board. Since I am using pictureboxes, what would be the best way to load the images and also the best method to be able to drag them around 1 by 1. This is almost like a paint program with brushes that can be moved around.

1) Draw three letter's 'P' 'B' & 'C' on a form (at a later date mutiples of each wil be added)
2) to be able to drag them anywhere on the form
3) to be able to lassoo them and drag them all at the same time.
For the moment the third option isn't important just as long as l can drag the letters.
