Question

我的对象看起来像这样：

public class ComponentProperty
{        
    public string Property { get; set; }
    public object Value { get; set; }
    public string DataType { get; set; }
    public string PropertyKey { get; set; }
    public string Unit { get; set; }
    public string DependencyType { get; set; }
    public object ListType { get; set; }

    public List<ComponentProperty> Properties { get; set; }
}

我在BindingList的以下形式中构建了信息，其中Output是：

public class ComponentPropertyList: BindingList<ComponentProperty>
{

}

情境：

组件属性列表绑定到 Infragistics Ultra WinGrid 以生成Master-Detail View，我在网格设置中进行了以下自定义：

    foreach (UltraGridBand band in ultraGrid1.DisplayLayout.Bands)
    {
        band.HeaderVisible = false;
    }
}

componentProperties集合可能具有N Level，具体取决于值。

CompoentProperty 1
--------＆GT; SubProperty1
----------------＆GT; SubSubProperty1
----------------＆GT; SubSubProperty1
CompoentProperty 2
--------＆GT; SubProperty2
----------------＆GT; SubSubProperty2
----------------＆GT; SubSubProperty2
----------------------＆GT; SubSubProperty3
----------------------＆GT; SubSubProperty3
---------------------------＆gt; SubSubProperty NN

问题：

布局不正确，将DataSource分配给网格后有很多条带ComponentProperties类和指定的Column Size对它没有任何影响。以前，我使用datatable作为需要替换对象数据源的数据源。是否需要使用对象数据源进行任何设置。

Lost of band showing rather than just 3 bands if i have 3 level hierarchy

Answer 1

我从Infragistics fourm得到了一些解决方案，解决了布局问题。在我使用IList时进行检查时，在表单加载事件中设置MaxBandDepth Property后，这些设置工作正常。

// Load only upto two descendant bands. So even if the data source has more than 3 level 
// deep hierarchy, the UltraGrid will only make use of first two levels and ignore the 
// levels deeper than that.
    this.ultraGrid1.DisplayLayout.MaxBandDepth = 3;

发生的问题类似于以下主题中提出的问题：
First Column of Wingrid Extending too large when datasource is IList

默认情况下，网格会同步每个波段的列宽。所以   在这种情况下你有一个递归数据源，那里   基本上是无限数量的波段，每个波段都是网格   缩进一点点。这意味着第一列变得非常大   为了容纳压痕一路向下   层次结构。默认情况下，网格限制为100个深度带，   但这仍然意味着100级的缩进。

因此，有很多方法可以解决这个问题。

将网格上的MaxBandDepth设置为较小的值。我推荐一个值   在5到8之间。这将给你相当不错的表现   体面的机器和大多数用户可能不会钻取超过5   无论如何，水平。您可以将AllowColSizing设置为Free。这将停止   网格来自同步列宽并允许每个波段   列要独立调整大小。

使用UltraWinGrid显示具有一些自定义网格外观设置的分层数据？
