title: How to Capture an OnMouseDown Event in a ArcMap Control?
body: <p>I have a Control in ArcMap in which I created with buttons, A Listbox and some more buttons.  I want to add coordinate items to the list box.</p>
  
  <p>Scenario:</p>
  
  <ol>
  <li>A user clicks a Add a Coordinate button on the control.</li>
  <li>The user then clicks on the map to add the coordinate find the coordinate on the map.</li>
  <li>The coordinate gets added to the list box. </li>
  </ol>
  
  <p>After I am done, I will run some analysis on the list box coordinates...  I just need to capture more than one coordinate.  So I need to find an OnMouseDown event that I can either attach onto of something along those lines.</p>
  
  <p>This is all being built in a control though, so I need to have the button on this control and NOT in a toolbar.</p>
  
  <p>Thanks All!</p>
