[Solved] WCF Service call during Cell Loaded Event

[Timothy]

I have a requirement to call a WCF Service and ping an IP Address which is equal to the current cell.value that is being loaded. The call to the service is below,

Private Sub CheckListItemssDataGrid_CellLoaded(ByVal sender As Object, ByVal e As Telerik.Windows.Controls.GridView.CellEventArgs) Handles CheckListItemssDataGrid.CellLoaded

       If TypeOf e.Cell Is GridViewCell Then

           Dim Row As GridViewRow = e.Cell.ParentOfType(Of GridViewRow)()

           Dim Hostname = TryCast(Row.Cells(0), Telerik.Windows.Controls.GridView.GridViewCell)

           HostnameValue = Hostname.Value.ToString
               client.ping(HostnameValue)


The Ping return value (True or False) is evaluated in a seperate sub routine (Ping Completed Routine). However I need to color the cell background red or white depending on the service call result (True of False). How can I do this if I have to leave the cell loaded routine in order to evaluate the return value of the service call?

Proble: Once I leave the cell loaded event I lose my ability to reference the current cell that was just loaded and this prevents me from painting the cell background.

Please help.

Hello,

 It will be better to implement this at your data level - property getter for example. When the service returns data you can raise PropertyChanged (your objects should be INotifyPropertyChanged) and in this case your RadGridView with defined CellStyleSelector will react immediately. 

All the best,
