ComponentOne FlexGrid for WPF and Silverlight
Bound FlexGrid
Features > Data Binding > Bound FlexGrid

Like other data visualization controls, FlexGrid supports bound mode and can be populated with data from various data sources. The C1FlexGrid class provides the ItemsSource property to populate data in the grid. In WPF, the ItemsSource property binds FlexGrid to IEnumerable interface, or to ICollectionView interface. In Silverlight, FlexGrid provides PagedCollectionView class that implements the ICollectionView interface. The PagedCollectionView constructor takes an IEnumerable object as a parameter and automatically provides all ICollectionView services.

The following image shows a bound FlexGrid.

Bound FlexGrid

The following code examples illustrate how to bind a list of customer objects to FlexGrid control. The code below causes the grid to scan the data source and automatically generate columns for each public property of the items in the data source. You can also customize automatically created columns using code, or disable automatic column generation altogether and create custom columns through code or XAML.

grid.ItemsSource = Customer.GetCustomerList(12);
List<Customer> list = GetCustomerList();
PagedCollectionView view = new PagedCollectionView(list);
grid.ItemsSource = view;

FlexGrid can also be bound directly to a list (customer list). However, binding to an ICollectionView is usually better as it retains a lot of the data configuration for the application, which can be shared across controls. If many controls are bound to the same ICollectionView object, they all show the same view. Selecting an item in one control automatically updates the selection on all other bound controls. Filtering, grouping, or sorting are also shared by all controls bound to the same view.

For example, the following code disables automatic column generation and specifies columns in XAML instead.

C#
Copy Code
<!-- create columns in a C1FlexGrid -->
<grid:C1FlexGrid x:Name="_flexiTunes"
     AutoGenerateColumns="False" >
   <grid:C1FlexGrid.Columns>
     <grid:Column Binding="{Binding Name}" Header="Title"
         AllowDragging="False" Width="300"/>
     <grid:Column Binding="{Binding Duration}"
         HorizontalAlignment="Right" />
     <grid:Column Binding="{Binding Size}"
         HorizontalAlignment="Right" />
     <grid:Column Binding="{Binding Rating}" Width="200"
         HorizontalAlignment ="Center" />
   </grid:C1FlexGrid.Columns>
</grid:C1FlexGrid>

Note that the binding can be used as an indexer into the grid's Columns collection. For example, to set the width of the "Rating" column to 300 pixels, use the following code.

C#
Copy Code
_flexiTunes.Columns["Rating"].Width = new GridLength(300);
