试图在代码隐藏中包装数据网格文本

Question

Using C# and WPF, I am trying to wrap the text in a DataGrid Column. I am setting the ItemsSource of the DataGrid in the code-behind, rather than using data binding.

As far as I can tell, there isn't a 'wrap' property for a datagrid, but it is possible to nest cell data inside of a textblock that can be wrapped. Unfortunately everything I've seen to do this uses data binding in the xaml, which would require a lot of refactoring, so I am trying to avoid it.

My xaml item:

<DataGrid x:Name="dgvOrderItems" AutoGeneratedColumns="DgvOrderItems_AutoGeneratedColumns" Height="570" VerticalAlignment="Stretch" Width="auto" HorizontalAlignment="Stretch" FontSize="10" Padding="0" Margin="0,20,0,0" ></DataGrid>

My code behind for the DgvOrderItems_AutoGeneratedColumns:

dgvOrderItems.SelectionUnit = DataGridSelectionUnit.FullRow;
dgvOrderItems.IsReadOnly = true;
dgvOrderItems.ColumnHeaderHeight = 15;
dgvOrderItems.Columns[0].Header = "Order Item";
dgvOrderItems.Columns[0].Width = 113;
dgvOrderItems.Columns[1].Visibility = Visibility.Hidden;
dgvOrderItems.Columns[2].Header = "Qty.";
dgvOrderItems.Columns[2].Width = 25;

As yet, I have been unable to find a good way to wrap the "Order Item" if the length exceeds the specified width.

After going back and forth with it, I decided to go with what @TerryTyson and @EdPlunkett suggested by refactoring it with better data binding. Thanks guys for the advice.

XAML:

<DataGrid x:Name="dgvOrderItems" Height="570" VerticalAlignment="Stretch" Width="138" HorizontalAlignment="Stretch" FontSize="10" Padding="0" HorizontalScrollBarVisibility="Hidden">
<DataGrid.ColumnHeaderHeight>20</DataGrid.ColumnHeaderHeight>
    <DataGrid.Columns>
        <DataGridTextColumn Header="Order Item" Width="108" Binding="{Binding ItemNumber}">
            <DataGridTextColumn.ElementStyle>
                <Style>
                    <Setter Property="TextBlock.TextWrapping" Value="Wrap" />
                </Style>
            </DataGridTextColumn.ElementStyle>
        </DataGridTextColumn>
        <DataGridTextColumn Header="Qty." Width="30" Binding="{Binding ItemQty}">
            <DataGridTextColumn.ElementStyle>
                <Style>
                    <Setter Property="TextBlock.TextAlignment" Value="Center" />
                </Style>
            </DataGridTextColumn.ElementStyle>
        </DataGridTextColumn>
    </DataGrid.Columns>
</DataGrid>

Class for my data:

public class SimpleOrderInfo
{
    public string ItemNumber { get; set; }
    public int ItemQty { get; set; }

    public SimpleOrderInfo(string itemNumber, int itemQty)
    {
        this.ItemNumber = itemNumber;
        this.ItemQty = itemQty;
    }
}

Setting my ItemsSource:

public List<SimpleOrderInfo> simpleOrderInfo = new List<SimpleOrderInfo>();
simpleOrderInfo = business.GetSimpleOrderInfo(orderNumber);
dgvOrderItems.ItemsSource = simpleOrderInfo;

I feel like this could still probably be cleaned up some, but it is working, and is much cleaner than what I started with.
