How to upload a datagrid to XML?

There is a DataGrid . There are problems with uploading content to XML.

Class to serialize

 [Serializable] public class Buttons { public bool VisibilityBut { get; set; } public string Name { get; set; } public string PathImag { get; set; } public string PathExe { get; set; } } 

If I do serialization like this

 XmlSerializer formatter = new XmlSerializer(typeof(Buttons)); using (FileStream fs = new FileStream(@"XML.XML", FileMode.OpenOrCreate)) formatter.Serialize(fs, DataGrid1); 

then the file is created empty and an exception is thrown

System.InvalidOperationException: "Error creating XML document." InvalidCastException`: Failed to cast the object type "System.Windows.Controls.DataGrid" to the type of "Button Panel. Buttons".

And if I do this:

 if (DataGrid1.ItemsSource == null) return; var serializer = new XmlSerializer(typeof(List<Buttons>)); var writer = new StreamWriter("XML.xml"); serializer.Serialize(writer, DataGrid1.ItemsSource as List<Buttons>); writer.Close(); 

then only the XML header is created in the file, and everything else is empty, by selecting the types, the solution is this.

 ObservableCollection<ButtonEIIS> collection = null; private void butSaveXML_Click(object sender, RoutedEventArgs e) // нажали кн. "Сохранить в XML" { var serializer = new XmlSerializer(typeof(ObservableCollection<Buttons>)); using (FileStream fs = new FileStream(@"XML.XML", FileMode.OpenOrCreate)) { serializer.Serialize(fs, DataGrid1.ItemsSource as ObservableCollection<Buttons>); } } 

in XAML binding such

 <DataGrid x:Name="DataGrid1" Margin="10,171,10,52" FontSize="14" AutoGenerateColumns="False"> <DataGrid.Columns> <DataGridCheckBoxColumn Header="Вид" Binding="{Binding VisBut}"/> <DataGridTextColumn Header="Надпись на кнопке (папка подсистемы)" Binding="{Binding NameSubEIIS}"/> <DataGridTextColumn Header="Полный путь к картинке" Binding="{Binding PathPNG}"/> <DataGridTextColumn Header="Полный путь к запускаемому приложению" Binding="{Binding PathEXE}"/> </DataGrid.Columns> </DataGrid>
