C#基于rounds实现ListView动态列：DataTemplate传参与UI异常

我需要通过编程方式创建ListView，从SQL Server加载数据，列表中的所有标签均通过ObservableCollection<Shooters>设置绑定。核心需求是根据名为rounds的变量动态调整ListView的列数。目前其余功能均符合预期，但以下代码会导致UI布局错乱：

var con = new CustomViewCell(Rounds);
var connect = await con.GetCellLayout(Rounds); // 返回组装完成的Grid布局

var ShooterDataTemplate = new DataTemplate(() =>
{
    return new ViewCell { View = connect }; // 将Grid布局赋值给ViewCell的视图
});

采用这种微软定义为内联数据模板的实现方式时，会出现包含相同信息的重复行，部分行还会缺失对应标签，整体UI布局错位。

微软给出的第二种实现方式如下：

ShooterListView.ItemTemplate = new DataTemplate(new TypeOf(CustomViewCell));

采用这种方式实现后UI显示正常，但存在明确问题：无法将rounds变量传递给CustomViewCell，而该变量是决定调用哪个方法生成对应列布局的核心参数。

两种场景下使用的网格布局设计完全一致，唯一区别是分别采用内联代码创建DataTemplate、以及指定自定义单元格类型的方式实现模板。由于指定类型的实现方式无法传入自定义的rounds参数，想了解如何解决内联代码方式的UI布局错乱问题。
