The drag-and-drop operation between controls in WinForms can be achieved by following these steps:<\/p>\n
Below is a simple example code demonstrating how to implement drag and drop operation between controls in WinForms<\/a>.<\/p>\n In this example, when the user clicks on the pictureBox1 control, they can drag the image within the control. When the drag enters the pictureBox2 control, it checks if the dragged data type is a Bitmap and allows the drop operation. When the drop occurs, the dragged image is set as the Image property of pictureBox2.<\/p>\n <\/p>\n More tutorials<\/p>\n Set in Python(Opens in a new browser tab)<\/span><\/a><\/p>\n What is the security mechanism of Cassandra?(Opens in a new browser tab)<\/span><\/a><\/p>\n How can data pagination be implemented in Cassandra?(Opens in a new browser tab)<\/span><\/a><\/p>\n How can virtual machine image formats be converted?(Opens in a new browser tab)<\/span><\/a><\/p>\n\/\/ \u5f00\u59cb\u62d6\u52a8\u64cd\u4f5c<\/span>\r\nprivate<\/span> void<\/span> pictureBox1_MouseDown<\/span>(object<\/span> sender, MouseEventArgs e<\/span>)<\/span>\r\n{\r\n pictureBox1.DoDragDrop(pictureBox1.Image, DragDropEffects.Copy);\r\n}\r\n\r\n\/\/ \u62d6\u52a8\u8fdb\u5165\u76ee\u6807\u63a7\u4ef6<\/span>\r\nprivate<\/span> void<\/span> pictureBox2_DragEnter<\/span>(object<\/span> sender, DragEventArgs e<\/span>)<\/span>\r\n{\r\n if<\/span> (e.Data.GetDataPresent(DataFormats.Bitmap))\r\n {\r\n e.Effect = DragDropEffects.Copy;\r\n }\r\n}\r\n\r\n\/\/ \u653e\u7f6e\u64cd\u4f5c<\/span>\r\nprivate<\/span> void<\/span> pictureBox2_DragDrop<\/span>(object<\/span> sender, DragEventArgs e<\/span>)<\/span>\r\n{\r\n pictureBox2.Image = (Image)e.Data.GetData(DataFormats.Bitmap);\r\n}\r\n<\/code><\/pre>\n
