c# - 在 ObjectListView C# 中生成列

Question

在普通的 ListView 中，我通常会动态生成列，例如：

        var list = new List<ColumnNameSize>();
        list.Add(new ColumnNameSize("Computer Name", 0));
        list.Add(new ColumnNameSize("Full Computer Name", 150));
        list.Add(new ColumnNameSize("Migrated", 150));
        list.Add(new ColumnNameSize("Disabled", 0));
        list.Add(new ColumnNameSize("Disabled & Not Migrated", 150));
        generateListView(listViewObjects, list);

        public static void generateListView(ListView varListView, List<ColumnNameSize> nameSizeList) {
        varListView.ClearColumns();
        foreach(ColumnNameSize nameSize in nameSizeList) {
            varListView.AddColumn(nameSize.ColumnName, nameSize.ColumnSize);
        }
    }

我将如何在ObjectListView中做到这一点。我尝试了多种组合：

    public void generateListView(ObjectListView varListView, List<ColumnNameSize> nameSizeList) {

        ArrayList myArrayList = new ArrayList();
        foreach (ColumnNameSize nameSize in nameSizeList) {
            OLVColumn columnHeader = new BrightIdeasSoftware.OLVColumn();  
            columnHeader.Width = nameSize.ColumnSize;
            columnHeader.Text = nameSize.ColumnName;
            myArrayList.Add(columnHeader);
            varListView.AllColumns.Add(columnHeader);
        }
        Object columnsHeader = myArrayList.ToArray();
        varListView.Columns.AddRange( columnsHeader);
    }

但似乎没有一个工作......

Answer 1

你能试试这个吗？

 public void generateListView(ObjectListView varListView, List<ColumnNameSize> nameSizeList) {

        List<OLVColumn>  columnsList = new List<OLVColumn>();
        foreach (ColumnNameSize nameSize in nameSizeList) {
            OLVColumn columnHeader = new BrightIdeasSoftware.OLVColumn();  
            columnHeader.Width = nameSize.ColumnSize;
            columnHeader.Text = nameSize.ColumnName;
            columnsList .Add(columnHeader);
            varListView.AllColumns.Add(columnHeader);
        }
        varListView.Columns.AddRange( columnsList.Cast<System.Windows.Forms.ColumnHeader>().ToArray());
    }

要在通过代码手动添加列后使其可见，您需要使用以下行重新构建它们：

varListView.RebuildColumns();

根据 Bala 的回答，您将获得以下代码：

public void generateListView(ObjectListView varListView, List<ColumnNameSize> nameSizeList)
{
    List<OLVColumn> columnsList = new List<OLVColumn>();
    foreach (ColumnNameSize nameSize in nameSizeList)
    {
        OLVColumn columnHeader = new BrightIdeasSoftware.OLVColumn();
        columnHeader.Width = nameSize.ColumnSize;
        columnHeader.Text = nameSize.ColumnName;
        columnsList.Add(columnHeader);
        varListView.AllColumns.Add(columnHeader);
    }

    varListView.Columns.AddRange(columnsList.Cast<System.Windows.Forms.ColumnHeader>().ToArray());
    varListView.RebuildColumns();
}

Answer 3

要使 ObjectListView 按预期工作，您必须将模型对象的所需属性的名称定义为 AspectName。

我宁愿一一添加列，而不是首先创建 ColumnNameSize 列表：

ObjectListView1.AllColumns.Add(new OLVColumn()
{
    Text = "Column Header",
    Width = 100,
    AspectName = "myProperty"
});

ObjectListView1.RebuildColumns();
