Why can't I bind the WPFToolkit DataGrid ItemSource to DataTable?

Question

In a Telerik control I was able to bind a DataTable directly to the ItemSource, but when I switched to the Codeplex WPFToolkit Datagrid

<dg:DataGrid Name="theGrid"/>
---
theGrid.ItemsSource = dt;

I get this error:

Cannot implicitly convert type 'System.Data.DataTable' to 'System.Collections.IEnumerable'.

How can I bind the DataTable to the WPFToolkit DataGrid?

Answer 1

Hi Edward

You'll have to project your datatable into something that implements IEnumerable as that is waht the DataGrid expects. The grid is a different implementation to the Telerik version so its hard to expect the same functionality from both.

I'm assuming support for this will be added in the future, but for now you can use the implementation of IListSource on DataTable. Call the GetList() method and use that as your data source. It's an explicit interface implementation so you'll need to cast:

var data = (myDataTable as IListSource).GetList();

I find the easiest way is:

myDataGrid.ItemsSource = myDataTable.DefaultView;

because DataView implements IEnumerable

Hello This is Aizaz, I am developing a Network Application named Protocol Inspector and had plan to develop around 32 applications in WPF but It is looking difficult to develop a single, because Microsoft is right now focusing on Silverlight (datagrid controls etc) and they are not paying attention towards WPF they will provide support in future.

The worst thing with Microsoft technologies is that next release it totally up side down of the previous release they change every thing, I don't know why ... so there is always a huge learning curve in learning new Microsoft technologies. Where as Java got a well managed Documentation where Microsoft lacks and they take previous things with them in next release so it is not hard to learn new technologies.

You could not bind datatable like this else you will have to tell in XAML like this

theGrid.ItemsSource = dt;
