c# - 使用带有一些自定义网格外观设置的 UltraWinGrid 显示分层数据？

Question

我有看起来像这样的对象：

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; }
}

我在以下形式的 BindingList 中构建了信息，其中 Output 是：

public class ComponentPropertyList: BindingList<ComponentProperty>
{

}

设想：

组件属性列表绑定到 aInfragistics Ultra WinGrid以生成主从视图，我在网格设置中进行了以下自定义：

}

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

CompoentProperty 1
--------> SubProperty1
---->SubSubProperty1
---------------->SubSubProperty1
CompoentProperty 2
--------> SubProperty2
----> SubSubProperty2 ----
>SubSubProperty2
---- ------------------>SubSubProperty3
---------->SubSubProperty3
------ --------------------->SubSubProperty NN

问题：

DataSource布局不正确，将网格指定为ComponentPropertiesClass 和 Specified后有很多 Banding对其Column Size没有任何影响。以前，我使用数据表作为需要替换为对象数据源的数据源。是否需要任何设置才能使用对象数据源。

Answer 1

我从 Infragisticsfourm 那里得到了一些解决方案，这些解决方案可以解决布局问题。正如我在使用时检查的那样，在表单加载事件中设置MaxBandDepth 属性IList后，这些设置可以正常工作。

// 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;

发生的问题与以下线程中的问题类似：
当数据源为 IList 时，Wingrid 的第一列扩展太大

默认情况下，网格会同步每个波段的列宽。因此，在这种情况下，您有一个递归数据源，基本上有无限数量的波段，并且对于每个波段，网格都会缩进一点。这意味着第一列变得非常大，以适应整个层次结构的缩进。默认情况下，网格将您限制为 100 个深度带，但这仍然意味着 100 级缩进。

所以有很多方法可以处理这个问题。

将网格上的 MaxBandDepth 设置为较小的值。我推荐一个介于 5 到 8 之间的值。这将在一台体面的机器上为您提供相当不错的性能，并且大多数用户可能不会钻取超过 5 个级别，无论如何。您可以将 AllowColSizing 设置为 Free。这将阻止网格同步列宽，并允许每个波段的列独立调整大小。
