如何在不绑定任何内容的情况下创建 wpf 数据网格？

Question

I want to create a datagrid without binding to anything. User can add/delete/edit data and the code will collect the data programatically. I did the following but the grid does not allow me to add new row.

<DataGrid Name="dgData" CanUserAddRows="True" MinHeight="100">
            <DataGrid.Columns>
                <DataGridTextColumn Header="Column1"></DataGridTextColumn>
                <DataGridTextColumn Header="Column2"></DataGridTextColumn>
            </DataGrid.Columns>
</DataGrid>

When I run the application, the grid is shown with only headers. Unlike winform DataGridView that gives an empty first row. There is no way I can add a new row on the GUI.

您仍然需要将ItemsSource设置（或绑定）到支持添加（实现IList ）的空集合，还应该将列绑定到item数据类型的属性（或让DataGrid为您创建它们），否则他们赢了“什么都没有。

I know my answer is pretty late, but someone might still come here and benift from it. So basically I did not find a way to fill the DataGrid without Binding in WPF but I found a way to make binding with an anonymous type with dynamically named object properties.

List<object> myList = new List<object>();
dynamic obj = new ExpandoObject();
((IDictionary<String, Object>)obj)["PropertyName"] = "PropertyValue";
myList.Add(obj);
MyDataGrid.ItemsSource = myList;
