Hello,
i´m trying to refresh a xamgrid dynamically but i can´t.
I have a object wich it is a list of objects and i visualize it with xamgrid.itemSource.
Then i modify or add an object and want to see the new xamgrid.
I tried with xamgrid.itemSource=the modify list but it doesn´t work.
this is my code.
Sub entityHandler(EntityObj As Object)
Try
If (EntityObj Is Nothing) Then
MessageBox.Show("No tiene datos cambiados")
Else
MessageBox.Show("Tiene datos cambiados")
Dim valuePropertyId As Object = EntityObj.GetType().GetProperty(Me.myEntityList.CampoId).GetValue(EntityObj, Nothing)
'here i add a entity to the list of entities
If valuePropertyId = 0 Then
Me.myEntityList.Entities.Add(EntityObj)
'here i search and modify an object
For i As Integer = 0 To Me.myEntityList.Entities.Count - 1
Dim valueProperty As Object = Me.myEntityList.Entities(i).GetType().GetProperty(Me.myEntityList.CampoId).GetValue(Me.myEntityList.Entities(i), Nothing)
If (valueProperty.Equals(valuePropertyId)) Then
Me.myEntityList.Entities(i) = EntityObj
'here i try to visualize the new list
Me.dataGrid.ItemsSource = Me.myEntityList.Entities
Exit For
End If
Next
'here i try to visualize the new list with the object add
Catch ex As Exception
MessageBox.Show("EntityHandler Error" & ex.Message)
End Try
End Sub
I tried to make a function
Me.LayoutRoot.Children.Clear()
Me.LayoutRoot.Children.Add(te)
but it doesn´t work because i´m working with a user control and is inside another controls. And it´s going to be use recursively.
Thank you for your support.
Sincerely
David A
Hello Stefan,
I have not yet succeeded. I think it´s because the xamgrid has no binding.
Right now we are changing our architecture to mvvm and implementing RIA Services.
And after that i will return with the xamgrid.
I will keep you informed of the progress.
Thank you Stefan for your concern.
Sincerely.
David A.
I am just checking the progress of this issue and was wondering if you managed to achieve your goal or if you need any further assistance on the matter.
Sorry Stefan, I misspelled your name.
Hello David,
I can suggest you implement the INotifyPropertyChanged in all your classes, in order to achive your goal. Here yo ucan read more about this interface:

Hope this helps you.
Hello Stephan,
Thank you so much for your support, i think i will not be able to figure it out. Your advice really helps me.
It works great for add.
But i´m still having problems with the modify issue.
The function
Private Sub dataGrid_DataObjectRequested(sender As System.Object, e As Infragistics.Controls.Grids.DataObjectCreationEventArgs)
has Infragistics.Controls.Grids.DataObjectCreationEventArgs and it works for add but not for modify.
I´m looking a parameter for modify, something like "DataObjectModifyEventArgs" or something like that but i´m having no luck.
Thank you for all the support, you are doing a great job.
Sincerelly.
