is there anyway to implement the drag and drop function for users to reorder the column sequence? i have tried several ways but it still not working, any hints can enlighten me? bottom is part of my code.
DataGridView1.AllowUserToOrderColumns = True
DataGridView1.SelectionMode = DataGridViewSelectionMode.FullColumnSelect
Private Sub DataGridView2_DragOver(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles
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.
In datagridview if I set the property allowusertoOrderColumns it is set for all columns but if I want to prevent it for some columns. Can I do it like setting some column property or by some code.
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.
Actually, Drag Drop is working as it is required but the problem i m suffering now is when i add the following code:
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.
My users need to be able to drag and drop a DataGridView row upward or downward to a new position. Can anyone save me the trouble of re-inventing the wheel.I am using VB.NET 2008
I want to make a drag and drop into two datadrigview but i don't know how to move the row that i select in the first datagridview into the second !
I have 2 Datagridview with 4 columns and 32 rows each other. And I want to move a row of DGV1 (source) into the DVG2 (destination) and i want that the selected row of DVG1 replace the row selected in DVG2.
Here my first little code :
Code: Private clickedRow As DataGridViewRow Private Sub DataGridView1_MouseDown(ByVal Sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseDown
Private Sub TextBox1_DragDrop(ByVal sender As Object, _ ByVal e As System.Windows.Forms.DragEventArgs) Handles DataGridView1.DragDrop If e.Data.GetDataPresent(DataFormats.Text) Then
[code].....
But when mouse hover to datagridview, the mouse symbol did not change. It should have to be Copy symbol but It did not. Please tell me why and how can i resolved it.
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 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 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 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]
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
For Each DGR As DataGridViewRow In dgvJobs.SelectedRows ' Added to stop error occuring when destination dgv columns do not exist If dgvProject.ColumnCount = 0 Then For Each ColumnHeader As DataGridViewColumn In dgvJobs.Columns Dim name As String = ColumnHeader.Name [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 am currently working on a drag and drop project and I was wondering if there is a way to drag picturebox1 and drop it in picturebox2; that will snap to a specific location in the picturebox2?
ListView Drag&Drop allow to Drag&Drop between form??

Can it be drap and drop item to other form control??How to write the event when mouse up at the other form control?
i use a linq query to pull data from an xml inventory and place it in a a DGV, problem is the column ordering appears to be in the same order as the properties and fields in the row object class and not the order extracted from the xml with LINQ. I suppose i could rearrange the class so that it refects the column ordering i need but i'm wondering is there a way i can control programatically the order of the columns for my DGV? and why does it use the class structure rather than the query structure anyway? the class is done alphabetically as i wrote it with class diagram and class details, the LINQ query is in the order i need it in.
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 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
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 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.
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.

Is it possible to reorder the elements of a drop down list (combobox) via drag and drop?For example, when the list is dropped down, I want the user to be able to drag the items up or down to reorder them. I tried this (and some google searching) but I'm wondering if its just not possible:
Private Sub cmbClassLists_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles cmbClassLists.MouseDown If cmbClassLists.DroppedDown And Not cmbClassLists.SelectedIndex = -1 Then
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)
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.
How to implement Drag and Drop multiple objects in the form in Visual Basic. The drag-able object will be provided within the same form but in a different panel. I must be able to delete the object also.
