Hi vinsibal,

I would like to use a typed DataTable as a data source of DataGrid instead of ObservableCollection. Could you please show me how to implement it?

Best Regards.

Kaschan,

In the sample, one of the windows uses a DataTable.DataView as the data source. Does that help?

Hi vinsibal,

Thanks for your reply, anyway it's not help. I understands that you use DataView as the data source of ComboBox. But my question is about data source of DataGrid.

Newbie question:

WHat if there is more than one row?

How would one filter the combobox based on another field/property in the same row.

ie. the combobox itemsource for each row (elementstyle) would have to be different.

I tried binding the EditingElementStyle to the filtered itemsource, and keep the ElementStyle bound to the non-filtered source - but no matter what I try,

the text for a selected value on a different row disappears when I change the filter (presumably because that value is no longer present in the current itemsource).

DUHHH...Never mind - your solution works fine for all rows...I'll just have to look a little more carefully.

.NET 3.5 SP1 and WPF DataGrid CTP are out now!

I've trying to populate a DataGridComboBoxColumn using a filtered ObjectDataProvider,

<ObjectDataProvider x:Key="ingregastobanProvider"

ObjectInstance="{StaticResource ingregastobanTableAdapter}"

MethodName="GetData">

<ObjectDataProvider.MethodParameters>

<sys:String>I</sys:String>

</ObjectDataProvider.MethodParameters>

</ObjectDataProvider>

Updating the MethodParameter in a MultiBinding make all rows lookup combobox values get changed, not only the actual row...so changing the filtered objectdataprovider seems to change the full datagrid row source.

Is a correct aproach?

I would appreciate some help. I've been spend 3 days tryinf to figuer it, and don't get any progress...
