无法在WPF中的DataGrid中显示列表项 [英] Unable to display list items in DataGrid in WPF

问题描述

我已经创建了一个类 DisplayTable ，下面将对此进行介绍。

I have created the class DisplayTable, which was mentioned below.

我还创建了一个列表来将类的内容添加到列表中。

I have also created one list to add the contents of the class to the list.

我将填充的列表推到了DataGrid中。但是我无法在DataGrid中查看它们。

I pushed the populated list to the DataGrid. But I'm unable to view those in the DataGrid. Kindly help in fixing this.

public class DisplayTable
{
    public int AnalyteId;
    public int UnitCode;
    public int ReferenceValue;
}

private void btnAddAnalyte_Click(object sender, RoutedEventArgs e)
{
    DisplayTable d = new DisplayTable();
    List<DisplayTable> list = new List<DisplayTable>();
    foreach (CheckBox item in this.AnalyteLitst.Items)
    {
        if (item.IsChecked == true)
        {
            d.AnalyteId = 1;
        }
    }
    foreach (CheckBox unit in this.UnitsList.Items)
    {
        if (unit.IsChecked == true)
        {
            d.UnitCode = 12;
        }
    }
    list.Add(d);
    dataGrid.AutoGenerateColumns = true;
    dataGrid.IsReadOnly = false;
    dataGrid.RowHeight = 30;
    dataGrid.ColumnWidth = 100;
    dataGrid.ItemsSource = list;
}

推荐答案

DataGrid仅自动为属性，因为每个列都会创建一个绑定，而WPF绑定需要 properties 。 DisplayTable 类声明 fields 。

DataGrid generates columns automatically only for properties, because each column creates a binding and WPF bindings require properties. DisplayTable class declares fields.

而不是

public int AnalyteId;

make

public int AnalyteId { get; set; }

并以相同方式修复其他数据成员

and fix other data members in the same way
