Thanks Bonnie,
That did it.

>>>Here's a little blurb I wrote up awhile back:
>>>
>>>Drag / Drop for Controls that do not have an ItemDrag event:
>>>
>>>
>>>private Control PickedUpControl;
>>>private Panel TargetArea;
>>>
>>>this.TargetArea.AllowDrop = true;
>>>
>>>private void DragControl_MouseDown(object sender, System.MouseEventArgs e)
>>>{
>>> this.PickedUpControl = (Control)sender;
>>> this.PickedUpControl.DoDragDrop(sender, DragDropEffects.Move);
>>>}
>>>private void TargetArea_DragEnter(object sender, System.Windows.Forms.DragEventArgs e)

>>> e.Effect = DragDropEffects.All;
>>>}
>>>private void TargetArea_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)
>>>{
>>> this.TargetArea.Controls.Add(this.PickedUpControl);
>>> Point xy = this.TargetArea.PointToClient(new Point(e.X, e.Y));
>>> this.PickedUpControl.Location = xy;
>>>}
>>>
>>>// The DragOver event is often redundant, but can be used to show the object moving
>>>private void TargetArea_DragOver(object sender, System.Windows.Forms.DragEventArgs e)
>>>{
>>> e.Effect = DragDropEffects.All;
>>> Point xy = this.PointToClient(new Point(e.X+1, e.Y+1));
>>> this.PickedUpControl.Location = xy;
>>>}
>>>>>>
>>>Another useful method if you need to actually *get* the object at that point in the DragDrop method is the .GetChildAtPoint() method (this would be *where* the Dragged-in control is being dropped, like say you were dropping the actual Text from one TextBox to another):
>>>
>>>
>>>private void TargetArea_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)
>>>{
>>> Point pt = this.TargetArea.PointToClient(new Point(e.X, e.Y));
>>> Control ToControl = this.TargetArea.GetChildAtPoint(pt);

>>> ToControl.Text = this.PickedUpControl.Text;
