Generating columns in ObjectListView C#

In normal ListView I usually generate columns on fly with something like:

        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);
        }
    }

How would I do it in ObjectList开发者_如何转开发View. I've tried multiple combinations:

    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);
    }

But none seems to work...

Can you try this?

 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());
    }

To make the columns visible after adding them manually through code, you need to rebuild them with the following line:

varListView.RebuildColumns();

Based on Bala's answer, you get the following code:

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();
}

For the ObjectListView to work as intended, you have to define the name of the desired property of your model object as AspectName.

Instead of first creating a list of ColumnNameSize, I'd rather add the columns one by one:

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

ObjectListView1.RebuildColumns();
