这是我第一次使用 WPF 数据网格。据我了解,我应该将网格绑定到我的视图模型中的公共属性。下面是 ViewModel 代码,当我逐步完成调试器时,GridInventory 被设置为包含 2606 条记录的列表,但是这些记录从未显示在数据网格中。我究竟做错了什么?
public class ShellViewModel : PropertyChangedBase, IShell
{
private List<ComputerRecord> _gridInventory;
public List<ComputerRecord> GridInventory
{
get { return _gridInventory; }
set { _gridInventory = value; }
}
public void Select()
{
var builder = new SqlConnectionBuilder();
using (var db = new DataContext(builder.GetConnectionObject(_serverName, _dbName)))
{
var record = db.GetTable<ComputerRecord>().OrderBy(r => r.ComputerName);
GridInventory = record.ToList();
}
}
}
我的 XAML 是
<Window x:Class="Viewer.Views.ShellView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="InventoryViewer" Height="647" Width="1032" WindowStartupLocation="CenterScreen">
<Grid>
<DataGrid x:Name="GridInventory" ItemsSource="{Binding GridInventory}"></DataGrid>
<Button x:Name="Select" Content="Select" Height="40" Margin="600,530,0,0" Width="100" />
</Grid>
</Window>
