title: How do I get the datatype of the column I'm sorting on in a GridView? (C#)
body: <p>I'm trying to convert some code that was written against the Telerik RadGrid control to work with the built-in GridView control. </p>
  
  <p>This line gets the DataType of the column you're sorting on using the RadGrid control. </p>
  
  <p>_sortBy.DataType = Grid.Columns.FindByDataField(e.SortExpression).DataType;</p>
  
  <p>I'm trying to do the same thing using the standard .NET GridView Control. </p>
  
  <p>How do you get the DataType of the column you're sorting on? </p>
  
  <p>Thanks in advance.</p>
