Question

我创建了新的Uwp项目我添加了MyToolkit Extended Dll

我在设计页面中添加了一个数据网格控件

<Page
    x:Class="App1.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:App1"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
   xmlns:MyControls="using:MyToolkit.Controls"
    mc:Ignorable="d">

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <MyControls:DataGrid Name="bala" VerticalAlignment="Stretch">

        </MyControls:DataGrid>
    </Grid>
</Page>

我添加的代码

//空白页面项目模板记录在https://go.microsoft.com/fwlink/?LinkId=402352&clcid=0x409

namespace App1
{
    /// <summary>
    /// An empty page that can be used on its own or navigated to within a Frame.
    /// </summary>
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            this.InitializeComponent();
        List<data> lst = new List<data>() { new data() { iD = "1", Name = "bala" }, new data() { iD = "1", Name = "bala" }, new data() { iD = "1", Name = "bala" } };
        MyToolkit.Controls.DataGridTextColumn column = new MyToolkit.Controls.DataGridTextColumn();
        column.Binding = new Binding() { ElementName="iD"};
        column.Header = "ID";
        bala.Columns.Add(column);
        MyToolkit.Controls.DataGridTextColumn column1 = new MyToolkit.Controls.DataGridTextColumn();
        column1.Binding = new Binding() { ElementName = "Name" };
        column1.Header = "Name";
        bala.Columns.Add(column1);
        bala.ItemsSource = lst;
        }
    }
    public class data
    {
        public string iD { get; set; }
        public string Name { get; set; }
    }
}

我面临崩溃问题。

但是设计方面我添加了它可以正常工作的列。代码方面我只面临问题。

 <MyControls:DataGrid.Columns>
            <MyControls:DataGridTextColumn Header="ID" Binding="{Binding iD}"></MyControls:DataGridTextColumn>
            <MyControls:DataGridTextColumn Header="Name" Binding="{Binding Name}"></MyControls:DataGridTextColumn>
        </MyControls:DataGrid.Columns>

我得到了运行时例外： 至少有一个对象必须实现IComparable。＆＃39;

您应该使用路径进行绑定

column.Binding = new Binding() { Path = new PropertyPath("iD") };                              
        column1.Binding = new Binding() { Path = new PropertyPath("Name") };

这样可以正常工作。

用于Uwp DataGrid的MyExtended Toolkit DataGrid TextColumn绑定崩溃问题
