Private Sub dataGrid1_AutoGeneratingColumn(ByVal sender As System.Object, ByVal e As System.Windows.Controls.DataGridAutoGeneratingColumnEventArgs)
    ' Modify the header of the Name column.
    If e.Column.Header.ToString() = "Name" Then
        e.Column.Header = "Task"
    End If
    '  Replace the DueDate column with a custom template column.
    If e.PropertyName = "DueDate" Then
        ' Create a new template column.
        Dim templateColumn As New DataGridTemplateColumn
        templateColumn.Header = "Due Date"
        templateColumn.CellTemplate = Me.Resources("dueDateCellTemplate")
        templateColumn.CellEditingTemplate = Me.Resources("dueDateCellEditingTemplate")
        templateColumn.SortMemberPath = "DueDate"
        ' ...
        ' Replace the auto-generated column with the templateColumn.
        e.Column = templateColumn

    End If
    ' Cancel AutoGeneration of all boolean columns.
    If e.PropertyType Is GetType(Boolean) Then
        e.Cancel = True
    End If
End Sub

private void dataGrid1_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    // Modify the header of the Name column.
    if (e.Column.Header.ToString() == "Name")
        e.Column.Header = "Task";
    // Replace the DueDate column with a custom template column.
    if (e.PropertyName == "DueDate")
    {
        // Create a new template column.
        DataGridTemplateColumn templateColumn = new DataGridTemplateColumn();
        templateColumn.Header = "Due Date";
        templateColumn.CellTemplate = (DataTemplate)Resources["dueDateCellTemplate"];
        templateColumn.CellEditingTemplate = (DataTemplate)Resources["dueDateCellEditingTemplate"];
        templateColumn.SortMemberPath = "DueDate";
        // ...
        // Replace the auto-generated column with the templateColumn.
        e.Column = templateColumn;
    }

    // Cancel AutoGeneration of all boolean columns.
    if (e.PropertyType == typeof(bool))
        e.Cancel = true;
}
