14 Mar 20192 minutes to read
You could perform text drag-and-drop operation between a TextEditor control like RichTextBox and GroupView by handling the GroupView’s DragEnter and DragLeave events as shown below.
string dragged = "";
// Get the text to be dragged.
private void groupView1_DragEnter(object sender, System.Windows.Forms.DragEventArgs e)
{
this.dragged = e.Data.GetData(typeof(string)) as string;
}
// Drop the selected text in the GroupView Item.
private void groupView1_DragLeave(object sender, System.EventArgs e)
{
Point pt = this.groupView1.PointToClient(Control.MousePosition);
if (this.groupView1.ClientRectangle.Contains(pt))
{
if (this.dragged != "")
{
GroupViewItem item = new GroupViewItem();
item.Text = this.dragged;
this.groupView1.GroupViewItems.Add(item);
}
}
this.dragged = "";
}Dim dragged As String = ""
' Get the text to be dragged.
Private Sub groupView1_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs)
Me.dragged = e.Data.GetData(Type.GetType(String)) as String
End Sub
' Drop the selected text in the GroupView Item.
Private Sub groupView1_DragLeave(ByVal sender As Object, ByVal e As System.EventArgs)
Dim pt As Point = Me.groupView1.PointToClient(Control.MousePosition)
If Me.groupView1.ClientRectangle.Contains(pt) Then
If Me.dragged.Equals("") Then
Else
Dim item As New GroupViewItem()
item.Text = Me.dragged
Me.groupView1.GroupViewItems.Add(item)
End If
Me.dragged = ""
End Sub
