title: event handler to detect mouse drag on picture box(winforms,c#)
body: <p>I am making simple paint application in which a line would be drawn whenever someone holds down the mouse button and drags(exactly like in windows paint).</p>
  
  <p>However i am having a hard time finding the suitable event handler for this. MouseDown is simply not working and MouseClick is only jotting down dots whenever i press a mouse down.</p>
  
  <p>Need help in this matter. </p>
  
  <p>Thanks.</p>
