Back in November, I got around to using Scott's cool routine for resizing DataGrid columns automatically. Now that I'm using it more often, I decided I wanted to make it a little more generic so that I didn't have to rewrite it for each DataGrid that I used it on.

With a simple change to using the 'sender', I no longer need to do any editing. Drop it in and wire it up! it's ready to go.

/// <summary>

/// Automatically resize the columns of a DataGrid to fit the

/// data within

/// </summary>

/// <param name="sender">The DataGrid that needs resizing</param>

/// <param name="e"></param>

private void DataSourceChanged( object sender, System.EventArgs e )




    Type       t = sender.GetType();

    MethodInfo m = t.GetMethod( "ColAutoResize", BindingFlags.NonPublic

      | BindingFlags.Instance );


    for( int i = ( (DataGrid) sender ).FirstVisibleColumn;

      ( i < ( (DataGrid) sender ).VisibleColumnCount ); i++ )


      m.Invoke( sender, new object[] {i} );



  catch( Exception ex )


    System.Diagnostics.Trace.Write( "Failed Resizing Columns: "

      + ex.ToString() );
