// create the dragPoint variable<br />
private static System.Drawing.Point dragPoint;<br />
<br />
<br />
private void MouseDown(object sender, MouseDownEventArgs e)<br />
{<br />
  // assign the dragPoint in MouseDown<br />
  dragPoint.X = e.X;<br />
  dragPoint.Y = e.Y;<br />
}<br />
<br />
// approach using PointToClient but it only drags from the top left hand corner at System.Drawing.Point(0, 0)<br />
private void DragOver(object sender, DragEventArgs e)<br />
{ <br />
   // cthis is the form that the control is dragged over and ctrl is the control dragged<br />
   System.Drawing.Point NewLocation = cthis.PointToClient(new System.Drawing.Point(e.X, e.Y));<br />
   ctrl.Left = NewLocation.X + 2;<br />
   ctrl.Top = NewLocation.Y + 2;<br />
}<br />
<br />
// approach using RectangleToClient but it only drags from the top left hand corner at System.Drawing.Point(0, 0). Would like to use the control.bounds as a rectangle to compare the dragPoint before the new control location is made.<br />
<br />
private void DragOver(object sender, DragEventArgs e)<br />
{ <br />
   // cthis is the form that the control is dragged over and ctrl is the control dragged<br />
  Rectangle boundingRect = ctrl.Bounds;<br />
  boundingRect.X = e.X;   // boundingRect.X = e.X - dragPoint.X ???<br />
  boundingRect.Y = e.Y;   // boundingRect.Y = e.Y - dragPoint.Y ???<br />
  boundingRect.Width = ctrl.Width;<br />
  boundingRect.Height = ctrl.Height;<br />
  Rectangle NewLocation = cthis.RectangleToClient(new   Rectangle(boundingRect.X, boundingRect.Y, boundingRect.Width, boundingRect.Height));<br />
  ctrl.Left = NewLocation.X + 2;<br />
  ctrl.Top = NewLocation.Y + 2;<br />
}<br />
<br />
<br />
Would really appreciate some insight as to how to drag a control in the DragOver event where the control is dragged from the dragPoint that is set in the MouseDown event and the dragPoint variable is set at the form level.

string sSearch = "-- --";
const string sRegEx = "[a-z]*[A-Z]*[0-9]*";
if (Regex.IsMatch(sSearch, sRegEx)) {
  // do something funny
}
