This simple code will allow users to implement drag and drop features in their applications
1) Set The AllowDrop property of the destination control to True
Destination Control is the control to where you will drag drop an Item
2) On the MouseDown Event of the Destination Control add
Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System
.Windows.Forms.MouseEventArgs) Handles sourceControl.MouseDown
sourceControl.DoDragDrop(sourceControl.SelectedItem, DragDropEffects.Copy)
End Sub
*Source Control Is the Control from which you will drag.
3)In the DragEnter event handler of the destination control add
Private Sub ListBox2_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles destControl.DragEnter
e.Effect = DragDropEffects.Copy
End Sub
4)In the DragDrop event of the destination control add
Private Sub ListBox2_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles destControl.DragDrop
destControl.Items.Add(e.Data.GetData("System.String"))
End Sub
5)For Droping Item in a textBox use the Following Code
Private Sub TextBox1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles TextBox1.DragDrop
TextBox1.Text &= " " & e.Data.GetData("System.String")
End Sub
Private Sub TextBox1_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles TextBox1.DragEnter
e.Effect = DragDropEffects.Copy
End Sub
This Finishes an Application that drag's data from one listbox and drops it into another.
Private Sub TextBox1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles TextBox1.DragDrop
TextBox1.Text &= " " & e.Data.GetData("System.String")
End Sub
Private Sub TextBox1_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles TextBox1.DragEnter
e.Effect = DragDropEffects.Copy
End Sub
This Finishes an Application that drag's data from one listbox and drops it into another.
