WPF DataGrid绑定到XAML中的DataTable [英] WPF DataGrid binding to DataTable in XAML

问题描述

我对WPF / XAML完全陌生。我正在尝试编制XAML代码以将DataTable绑定到DataGrid。我所拥有的是实现INotifyPropertyChanged的自定义DataContainer类的实例。此类具有一个属性：

I'm completely new to WPF/XAML. I'm trying to work out XAML code to bind a DataTable to DataGrid. What I have is an instance of custom DataContainer class which implements INotifyPropertyChanged. This class has a property:

private DataTable totalsStatus = new DataTable();
public DataTable TotalsStatus
{
    get { return totalsStatus; }
    set
    {
        totalsStatus = value;
        NotifyPropertyChanged("TotalsStatus");
    }
}

现在，在我MainWindow的C'tor中

now, in the C'tor of my MainWindow I have this, which works like a charm:

Binding b = new Binding();
b.Source = DataContainer;
b.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
b.Path = new PropertyPath("TotalsStatus");
DataGridMain.SetBinding(DataGrid.ItemsSourceProperty, b);

如何在XAML中进行此绑定？

How do I make this binding in XAML?

推荐答案

您需要使用 objectdataprovider 。

<ObjectDataProvider x:Key="yourdataproviderclass" 
                    ObjectType="{x:Type local:yourdataproviderclass}" />

<ObjectDataProvider x:Key="dtable" 
                    ObjectInstance="{StaticResource yourdataproviderclass}"
                    MethodName="GetTable"/> <!--here would be the method that returns your datasource-->

然后您可以使用Xp
$ b将其绑定到数据网格$ b

Then you can bind it to your datagrid in XAML with

<DataGrid ItemsSource="{Binding Source={StaticResource dtable}}" ></DataGrid>

虽然在xaml中有不同的绑定方法，所以请多加尝试。

There are different ways to do bindings in xaml though, so play around with it a bit.
