Binding to SelectedItems count property in Xamdatagrid

170

infra posted over 13 years ago

Hi,

I am working on showing status information on the number of currently selected records in xamdatagrid.

For this I am assuming that I need to bind to the SelectedItems.Count property to a textblock ? I am new to wpf and infragistics...can you please provide some sample code to achieve this?

Thanks!

I have resolved this myself. Here is the working code for WPF and VB:

Private Sub xamDataPresenterPublicationCollection_SelectedItemsChanged(sender As System.Object, e As Infragistics.Windows.DataPresenter.Events.SelectedItemsChangedEventArgs) Handles xamDataPresenterPublicationCollection.SelectedItemsChanged

'While there is a collection of the currently selected Records (i.e., myDataGrid.SelectedItems.Records)

'there is no collection that holds the DataItems of those currently selected Records.

'You have to create and populate that collection manually by iterating through the Records in

'myDataGrid.SelectedItems.Records and adding their respective DataItems to the collection.

Dim _publicationModel As PublicationModel

Dim _selectedPublicationModels As New ObservableCollection(Of PublicationModel)

Dim _record As DataRecord

For Each _item In xamDataPresenterPublicationCollection.SelectedItems()

If (TypeOf _item Is Infragistics.Windows.DataPresenter.DataRecord) Then
_record =

DirectCast(_item, DataRecord)
_publicationModel =

DirectCast(_record.DataItem, PublicationModel)
_selectedPublicationModels.Add(_publicationModel)

End If

Next

_publicationTabViewModel.PublicationSelection = _selectedPublicationModels

End Sub
