[Solved] GridView do not Rebinding When i changed itemsource binding

[chinbnhike]

Hi,

I have a property :

 

Protected WithEvents m_TabDetailDomainDataSource As DomainDataSource

 

 

Public ReadOnly Property TabDetailData()
        Get
            If m_TabDetailDomainDataSource IsNot Nothing Then
                Return m_TabDetailDomainDataSource.Data
            End If
            Return Nothing
        End Get
    End Property

And XamWebGrid:

<telerikGridView:RadGridView ItemsSource="{Binding TabDetailData}" />

 

When m_TabDetailDomainDataSource.Data have any row, grid binding ok.
when i reload data and m_TabDetailDomainDataSource.Data have not any row, grid do not rebinding and row AddNewItem is disable. Why?

Thanks,

Hi,

Can you post more info about your grid version?

Hello,

I've checked this and indeed the grid cannot resolve item type when the collection is empty - you will get exactly the same result with standard Silverlight DataGrid. This can be considered as a problem related to RIA services since currently there is not valid way (except reflection which is highly undesirable) to achieve this.

Possible approach will be to return Enumerable.Empty(Of YourItemType)() when m_TabDetailDomainDataSource.Data is empty.
