In WPF, you can bind a DataGrid control to multiple arrays by using a MultiBinding. Here is an example of how to bind two arrays, “array1” and “array2”, to a DataGrid:
- In your XAML code, create a DataGrid and give it a name, for example “myDataGrid”.
- Create a MultiBinding object and set its Converter property to a class that implements the IMultiValueConverter interface. This class will be responsible for merging the two arrays into a single collection that can be bound to the DataGrid.
- In the XAML, define a binding for each array and set their Source property to the array’s name.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | <DataGrid x:Name="myDataGrid"> <DataGrid.Resources> <local:ArrayConverter x:Key="arrayConverter"/> </DataGrid.Resources> <DataGrid.RowDetailsTemplate> <DataTemplate> <DataGrid ItemsSource="{Binding Path=Array1, Converter={StaticResource arrayConverter}}"> <DataGrid.Columns> <DataGridTextColumn Binding="{Binding}" /> </DataGrid.Columns> </DataGrid> </DataTemplate> </DataGrid.RowDetailsTemplate> </DataGrid> |
In your C# code, set the DataContext of the DataGrid to an instance of a class that has properties for the two arrays.
1 2 3 | myDataGrid.DataContext = new { Array1 = array1, Array2 = array2 }; |
Create the ArrayConverter class
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | public class ArrayConverter : IMultiValueConverter { public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture) { return values.ToList(); } public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture) { throw new NotImplementedException(); } } |
This should bind the two arrays to the DataGrid, with each array being displayed in its own column.
