In the complete code below, a TextBox control is the control being the drop will occur. String files = (string)e.Data.GetData(DataFormats.FileDrop) Private void txtFolderPath_DragDrop(object sender, DragEventArgs e) The DragDrop event for the control where the drop will occur, retrieve the data being dragged using the GetData. If (e.Data.GetDataPresent(DataFormats.FileDrop)) Private void txtFolderPath_DragEnter(object sender, DragEventArgs e)

In this case it is FileDrop, which specifies the Windows file drop format. The DragEnter event for the control where the drop will occur, do the type-checking here to ensure that the data being dragged is of an acceptable type. Set the property called AllowDrop to true on the selected control. Working with the event arguments of these events eventually you can facilitate drag and drop. So I just want to share it with you all through a simple example.ĭrag-and-drop operations in WinForms accomplish via handling of a series of events, mostly with the DragDrop, DragEnter and DragLeave. Also it is possible to use various Control elements for implementation.Last evening I came up with a requirement to drag a folder path into a TextBox in one of my Windows form applications. Note: It is possible to implement drag-and-drop for both files and folders. Alternatively file variable equals nullĭragDrop.DoDragDrop(this, new DataObject(DataFormats.FileDrop, new string ), DragDropEffects.Move) If(file!=null) //Check that item is really selected. Var file = lv_list.SelectedItem as FileObject //Taking the selected object as FileObject If (e.MouseDevice.LeftButton=.Pressed) //Checking that leftbutton is pressed Private void lv_list_MouseMove(object sender, e) To drag some file from the list is it necessary to select it and put cursor in some folder (or browser window etc) realising the left button of the mouse. That is why ToString() is overridden in FileObject, to show short file name in the list. To show textual representation of the items ListView calls method ToString() that is marked as virtual in object class. Note: ListView can put any object to its items property.
Lv_(new FileObject(Path.GetFileName(path), new_path)) //adding FileObject (that stores file info) to the list String new_path = DirPath + Path.GetFileName(path) //New file pathįile.Copy(path, new_path) //copping dragged file by new_path add every file to the list copping them to the application directory String file_pathes = (string)e.Data.GetData(DataFormats.FileDrop) /*file_pathes contains pathes of dragged selected files*/ Private void lv_list_Drop(object sender, DragEventArgs e)
Public readonly string DirPath = /*path to the folder where the executable file is*/

to drop some file to some folder from listĭragging the file to ListView, it is possible to handle drop event and get the full file`s path.Public FileObject(string name, string fullname)īy means of the following code user is able: In order to simplify the logic of the program, let`s add a class and name it FileObject, that contains Name (image.jpeg, essay.txt etc) and Fullname (C:/somefolder/image.jpeg, E:/myessays/essay.txt etc). Add Drop and MouseMove handlers to ListView.To make it work you should get on with installed Visual Studio. Basic priciples of Object-oriented programming.To understand the following sample you should already know: Drag-and-Drop effect will simplify file manipulation between browser, computer file system and desktop applications. Developing desktop WPF or WinForm projects, you can stumble upon an idea of creating drag & drop functionality.
