使用例

The folllowing shows how to specify default settings for label text allignment, trimming and wrapping as well as how to override those settings for a specific field based on its data type.

C#

public partial class Window2 : Window
{
    public Window2()
    {
        InitializeComponent();

        // Set the default label text alignment, trimming and wrapping settings
        this.XamDataGrid1.FieldSettings.LabelTextAlignment = TextAlignment.Left;
        this.XamDataGrid1.FieldSettings.LabelTextTrimming = TextTrimming.CharacterEllipsis;
        this.XamDataGrid1.FieldSettings.LabelTextWrapping = TextWrapping.Wrap;

        // wire up the FieldLayoutInitialized event to override the
        // text alignment based on the data type of the field
        this.XamDataGrid1.FieldLayoutInitialized += new EventHandler<Infragistics.Windows.DataPresenter.Events.FieldLayoutInitializedEventArgs>(OnFieldLayoutInitialized);
    }

    void OnFieldLayoutInitialized(object sender, FieldLayoutInitializedEventArgs e)
    {
        foreach (Field field in e.FieldLayout.Fields)
        {
            // If the type is numeric then align the label on the right
            Type dataType = field.DataType;
            if (dataType == typeof(double) ||
                dataType == typeof(float) ||
                dataType == typeof(int) ||
                dataType == typeof(decimal))
                field.Settings.LabelTextAlignment = TextAlignment.Right;
        }
    }
}
