Objectlistview双击解释

Question

我正在尝试在 objectlistview 对象中实现 doubleclick 函数。

根据开发人员的说法，应该使用 ItemActivate 而不是 MouseDoubleClick。

所以我想到了这个：

    private void treeListView_ItemActivate(object sender, EventArgs e)
    {
        try
        {
            ListView.SelectedIndexCollection col = treeListView.SelectedIndices;

            MessageBox.Show(col[0].ToString());
        }
        catch (Exception e3)
        {
            globals.logfile.error(e3.ToString());
            globals.logfile.flush();
        }
        finally
        {
        }
    }

它为每个双击的行提供一个值。但是我如何从该行中获取详细信息？

这是我现在使用的完整解决方案：

    private void treeListView_ItemActivate(object sender, EventArgs e)
    {
        try
        {
            var se = (StructureElement)treeListView.GetItem(treeListView.SelectedIndex).RowObject;
            MessageBox.Show(se.id.ToString());
        }
        catch (Exception e3)
        {
            globals.logfile.error(e3.ToString());
            globals.logfile.flush();
        }
        finally
        {
        }
    }

Answer 1

Which comes up with a value for each double clicked row. But how do I get the details from that row?

我认为您必须像这样使用底层 OLVListItem 访问 RowObject：

private void treeListView_ItemActivate(object sender, EventArgs e) {
    var item = treeListView.GetItem(treeListView.SelectedIndex).RowObject;     
}

Answer 2

这就是我现在从树列表视图中获取数据的方式：

private void treeListView_ItemActivate(object sender, EventArgs e)
{
    try
    {
        var se = (StructureElement)treeListView.GetItem(treeListView.SelectedIndex).RowObject;
        MessageBox.Show(se.id.ToString());
    }
    catch (Exception e3)
    {
        globals.logfile.error(e3.ToString());
        globals.logfile.flush();
    }
    finally
    {
    }
}
