Fair enough, rather than debate the design pros and cons I think this code
is what you're looking for.
Note: This will only work for RichTextBox controls and not standard
textboxes. The reason being that a standard textbox loses it's selectedtext
BEFORE the mousedown event gets processed.
Private Sub RichTextBox1_DragDrop(ByVal sender As Object, ByVal e As
System.Windows.Forms.DragEventArgs) Handles RichTextBox1.DragDrop
RichTextBox1.Text =
RichTextBox1.Text.Insert(RichTextBox1.SelectionSta rt,
e.Data.GetData(System.Windows.Forms.DataFormats.Te xt, True))
End Sub
Private Sub RichTextBox2_MouseDown(ByVal sender As Object, ByVal e As
System.Windows.Forms.MouseEventArgs) Handles RichTextBox2.MouseDown
If RichTextBox2.SelectedText.Length > 0 Then
Dim s As String = RichTextBox2.SelectedText
RichTextBox2.DoDragDrop(s, DragDropEffects.Copy)
End If
End Sub
Private Sub RichTextBox1_DragEnter(ByVal sender As Object, ByVal e As
System.Windows.Forms.DragEventArgs) Handles RichTextBox1.DragEnter
If e.Data.GetDataPresent(DataFormats.Text) Then
e.Effect = DragDropEffects.Copy
End If
End Sub

| Cameron,
|
| I think the Drag & Drop, in this case, may simplify the work of a user.
| What is prefered?
| 1) select text -> do copy -> go to the other field -> do paste
| OR
| 2) select text -> drag to the other field
|
| When you drag an image control which present an image object, you dont
| mean to accept the all control. you want in only to transfer the image.
| same with listbox and treeview etc. in these two cases, you are not
| interested in draging a line, you are interested in transferring their
| text.
| (We did got a positive feedbacks from users)
|
| Is There a technical solution to this problem, in the current version of
| .Net 2003?
