[2008] Datagridview Drag Drop : No Duplicates?
Jan 18, 2009
I am trying to drag & drop rows from datagridview1 to datagridview2 using the code below.My question is : how do I check for duplicates in the target datagridview before completing the drop.ie: If Jerry has already been drag dropped to datagridview2 then say, "Jerry is already in the list. Are you sure you want to add a duplicate ?"
Public Class frmDataGrid
' Some Properties that I have set for the Grid
' SelectionMode = FullRowSelect [For both the Grids]
' AllowDrop = True [For Grid DataGridView2]
[code]....

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?

I'm creating an application in which the form contains one datagridview and 20 pictureboxes.When the DGV is populated, the user will drag a row from DGV and drop in any one of the pictureboxes.The picturebox should able evaluate a column value(say column 1) from the dropping row and according to that it should change its picture.

DataGridView1.DoDragDrop(datarow, DragDropEffects.Copy Or DragDropEffects.Move)
in the mousedown event of datagridview. In datagridview, i m not able to sort the column of datagridview.

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'm implementing drag and drop functionality between two datagridviews. This works as intended with one exception: it is possible to drag and drop within the same datagridview. This results in duplicated rows. I want to limit the functionality so that I can only drag from one datagridview to another.[code]

I have implemented couple of websites) drag and drop functionality between two Datagridviews (i.e to be able to add/remove columns on the fly). After much playing, I have managed to make this work, however it now presents a new issue - I cannot resize the columns.Below is the code for this, but I can't see how I would need to change to accomodate the resize (the drag and drop effects dont have it as an option, so I assume I need to stop the dodragdrop when the resize is taking place, but I'm not sure how to do this.

I am trying to develop a scheduler for my workplace for which I am using a datagridview. The data displayed in the datagridview is bound to a SQL server database.
I need to be able to drag and drop rows so that the any job with a high priority and a nearer deadline can just be dragged from anywhere in the grid and dropped to the topmost point in the grid. I don't mind using two buttons (up and down) to do it either. But I am not able to figure out a way to do it.

I'm writing an application for seat reservations. I use a DataGridView to represent seats. Each free seat is coloured in green and occupied seats are in blue.DataGridView is populated with names from database and user could add a name to a seat choosing from a list.Moreover the user has the possibility to move a name from one seat to another - not occupied via drag and drop operation.Eveything works well, but when moving a name from one cell to another I have to position the cursor over a cell that is one row above and four columns on the left of that one I choose.Which is the reason? Here is the code

I'm making a form where I have two datagridviews. The first dgv is databound to a database. The second dgv is not databound. I want to allow users to drag rows from dgv1 and drop them on dgv2. At the moment I have managed to get it to the point where I can drag from dgv1 to dgv2 but the result is an empty row being added. When I try adding a row without using .Clone I get this error "Row provided already belongs to a DataGridView control."

I am putting together two programs... basically one to enter data into a sql server 2000 database, and one to view the entered data and modify some fields. The data-entry part works well, but the second part is giving me some problems.ince the second part should really be a simple program, I created a DataGridView of my sql server table via drag&drop (just pulled the table from the data sources). Now I need to save back any changes to the DB. The part giving me problems is the OleDBCommandBuilder:
cBuilder = New OleDbCommandBuilder(FteuStoerungsmeldungAuftragTableAdapter)

I have a VB .NET (VS 2008) application which allows the user to drag and drop a xls file onto the form and a DataGridView fills with the xls sheet data. The user than can apply changes to the data or add entries. Data integrity is checked during the load into the DataGridView (duplicates are removed and invalid entries are filtered out). After doing all this the user can click a button and the data is uploaded to a SQL server (2008) DB. I have a primary key set up (row number) and I have a compound key in the SQL table.
It is all working beautifully. Now here is my question:
I want to check for duplicate entries (between SQL server and DataGridView data) before the data is uploaded and commited to the table. What would be the most efficient way to that?

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.

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.
