title: Binding DataGrid with dataset and set columns width
body: <p>I have DataGrid, this datagrid has a binding with a dataset</p>
  
  <pre><code>&lt;asp:DataGrid runat="server" ID="myGrid"&gt;
      &lt;Columns&gt;
          &lt;asp:BoundColumn DataField="MyField1" HeaderText="MyField1"&gt;&lt;/asp:BoundColumn&gt;
          &lt;asp:BoundColumn DataField="MyField2" HeaderText="MyField2"&gt;&lt;/asp:BoundColumn&gt;
      &lt;/Columns&gt;                
  &lt;/asp:DataGrid&gt;
  
  myGrid.DataSource = GetMyDataset();
  myGrid.DataBind();
  </code></pre>
  
  <p>That's work but I see has column all the fields of my dataset + the 2 columns defined. 
  I'd like see only the columns.</p>
  
  <p>And how set the column width % ?</p>
  
  <p>Any idea ?</p>
  
  <p>Thanks,</p>
