In the Documentation has this sample: Private Sub ListView1_RowPopulating( _ ByVal e As MicroFour.StrataFrame.UI.Windows.Forms.RowPopulatingEventArgs) _ Handles ListView1.RowPopulating '-- Establish locals Dim loBO As CustomersBO '-- Get the reference to the business object loBO = e.BusinessObject If loBO.cust_gender = 0 Then '-- The customer is a male, set the background color to blue ' and set the image key to the boy icon e.RowBackColor = Drawing.Color.LightBlue e.ImageKey = "boy.ico" Else '-- The customer is a girl, set the background color to pink ' and set the image key to the girl icon e.RowBackColor = Drawing.Color.Pink e.ImageKey = "girl.ico" End If '-- The fourth column has been configured to PopulateThroughEvent If loBO.cust_email.Length > 0 Then '-- We have an email in the record e.Values(3).DisplayValue = loBO.cust_email Else '-- We don't have an email for this customer e.Values(3).DisplayValue = "unavailable" End If End Sub and I translated to c#: private void listView1_RowPopulating(MicroFour.StrataFrame.UI.Windows.Forms.RowPopulatingEventArgs e) { MesasBo mesas = new MesasBo(); mesas = e.BusinessObject; } and I get this error: Error 10 Cannot implicitly convert type 'MicroFour.StrataFrame.Business.BusinessLayer' to 'M2BusinessObjectLibrary.MesasBo'. An explicit conversion exists (are you missing a cast?) D:\Projetos\Business Enterprise\M2FoodService\Form1.cs 65 24 M2FoodService I need a quick solution for this problem. at, Marcio Valerio da Silva Edited 13 Years Ago by Marcio Valerio Silva

In this example, the explicit conversion cannot happen between a BusinessLayer and your BO type. Just cast it: MesasBo mesas; mesas = (MesasBo)e.BusinessObject; Also, don't create a new instance of mesas because you are pushing a reference to that variable. So you don't want to create an instance of it first, that will just cause a potential memory leak since you didn't dispose of the object. Though no handlers were created either, so it would most likely have cleaned itself up through the collector. But this is still not a good way to setup a variable that will have a reference pushed into it.
