title: Custom Binding of multiple fileds in Custom DataGridViewColumn(WinForms)
body: <p>I have a question regarding a data binding(of multiple properties) for custom DataGridViewColumn. 
  Here is a schema of what controls that I have, and I need to make it bindable with DataGridView datasource. Any ideas or a link to an article discussing the matter? </p>
  
  <p><strong>Controls</strong></p>
  
  <ul>
  <li>Graph Control(custom):  Displayed in
  the custrom DataGridView column. Has
  properties like "Start Date",
  "EndDate", Windows Chart control,
  which is itself, bindable, etc. </li>
  <li>Custom cell(DataGridViewCustomCell inherits
  from DataGridViewCell) that holds
  the Graph control and processes some
  events(OnEnter event, for example,
  passes the focus to the custom Graph
  column for drag-n-drop type of
  events, etc.)</li>
  <li>Custom column(DataGridViewCustomColumn
  inherits from DataGridViewColumn)
  that defined the cell template type:
  CellTemplate = new
  DataGridViewCustomCell(); and also a
  primary choice for data binding</li>
  </ul>
  
  <p><strong>Data Structure:</strong> </p>
  
  <ul>
  <li>Main table to be displayed in other DataGridView Columns</li>
  <li>Graph table - related to the Main table via parent-child relationship. Holds graph data</li>
  <li>Chart table related to the graph table via parent-child relationship. Holds data for the win-form chart, which is a part of my Graph control.</li>
  </ul>
  
  <p>So far I cannot even bind data from the Graph table to by Graph control or Graph-holding Column/Cell. </p>
