Question

我一直在寻找这个，但我没有找到一些正在做我想要的东西。下面附带的截图是我想要创建的，这是在VBA中完成的，但我尝试使用WPF在C＃中创建它。我正在导入具有以下结构的CSV文件：的 “ID”， “NAME”，CheckedINT
例如
“1662”，“BØRSTER”，1 ＆lt; - 1 =已选中，0 =未选中。

因此，当我导入文件时，它会在列表视图中显示信息。但是，我无法为每个项目/记录创建该复选框。我试图在XAML文件中创建它如果你需要一些代码，例如要将数据加载到列表视图中，请告诉我。我对C＃很新，所以非常感谢（使用VS15）。

将listview的第一列定义修改为

                    <GridViewColumn Header="ID" Width="50">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <CheckBox Content="{Binding sID}" />
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>

我相信它会解决你的问题。数据绑定可能会受到影响，您需要更多的XAML /代码来处理它。

我在这里做的是采用GridViewColumn数据模板的默认定义，并将其替换为我自己的。您可以在Data templating主题中详细了解它。

教我错了，但您的csv文件包含ID, Name, IsChecked列，您将其解析为new Store(id: data[0], strName: data[1], strImportFile: data[2])。

因此，按照您的示例，新Store对象的属性将具有以下值：

public class Store
{
    public string sName { get; set; }         // BØRSTER
    public string sImportFile { get; set; }   // 1 
    public string sID { get; set; }           // 1662

    public Store(string id, string strName, string strImportFile)
    {
        sName = strName;
        sImportFile = strImportFile;
        sID = id;
    }
}

您应该为您的类添加另一个属性，并为构造函数添加另一个参数：

public bool IsChecked { get; set; }

public Store(string id, string strName, string isChecked, string strImportFile)
{
    sID = id;
    sName = strName;

    IsChecked = isChecked == "1";

    sImportFile = strImportFile;
}

现在您可以通过调用
来创建新的Store实例 new Store(data[0], data[1], data[2], fileName)。

绑定现在应该看起来像 <CheckBox IsChecked="{Binding IsChecked}" Content="{Binding sID}" />

至少让我给你一个善意的建议。您可以查看Microsoft Naming Guidelines。例如：属性应该在PascalCasing中命名，你也应该避免使用像strName这样的匈牙利符号。但这只是我个人的意见。
