How to set the DataSource of a DataGrid in WPF?
提问by Miguel
I need to set a table from a database to be the DataSource of a GridGrid in WPF. In Windows Forms the property is called DataSourcebut in WPF no such property exists, so how can i do it?
我需要将数据库中的表设置为 WPF 中 GridGrid 的数据源。在 Windows 窗体中，该属性被调用，DataSource但在 WPF 中不存在这样的属性，那么我该怎么做呢？

You can use the ItemsSourceproperty :
您可以使用该ItemsSource属性：
<ListView ItemsSource="{Binding YourData}">
<ListView.View>
<GridView>
<!-- The columns here -->
</GridView>
</ListView.View>
</ListView>
If you prefer to use code-behind rather than a binding, just give a name to the ListViewand set the ItemsSourceproperty in code:
如果您更喜欢使用代码隐藏而不是绑定，只需为 命名ListView并ItemsSource在代码中设置属性：
listView1.ItemsSource = YourData;
You can also use the ItemsSourceproperty with other list controls (DataGrid, ListBox, ComboBox, etc), since it is defined in the ItemsControlbase class.
您也可以使用ItemsSource属性与其他列表控件（DataGrid，ListBox，ComboBox等），因为它是在定义的ItemsControl基类。
EDIT: if the data source is a DataTable, you can't assign it directly to ItemsSourcebecause it doesn't implement IEnumerable, but you can do it through a binding:
编辑：如果数据源是 a DataTable，则不能直接将其分配给，ItemsSource因为它没有实现IEnumerable，但您可以通过绑定来完成：
listView1.SetBinding(ItemsControl.ItemsSourceProperty, new Binding { Source = YourData });

This is simple an example:
这是一个简单的例子：
XAML part:
XAML 部分：
<DataGrid Name="dataGrid1" Width="866" Height="auto" HorizontalAlignment="Left" VerticalAlignment="Top" />
C# part:
C# 部分：
... [code to read and fill your table ] ...
... [阅读和填写表格的代码] ...
da.Fill(myDataTable);
dataGrid1.ItemsSource = myDataTable.DefaultView;
And now your DataGrid will be filled with your DataTable
现在您的 DataGrid 将填充您的 DataTable

The GridViewis a view and not a standalone control as far as i know, you would normally use it as the view of a ListView. In WPF the property for data population is called ItemsSource, you probably want to either use a ListViewor DataGridto display your data that way.
GridView据我所知，这是一个视图而不是一个独立的控件，您通常会将它用作ListView. 在 WPF 中，数据填充的属性称为ItemsSource，您可能希望使用ListView或DataGrid以这种方式显示您的数据。

You can use below both ways to bind the datatable to datagrid in WPF.
您可以使用以下两种方式将数据表绑定到 WPF 中的数据网格。
datagrid.ItemSource = mydt.DefaultView();
datagrid.DataContext = mydt.DefaultView();
