How can I avoid to use typeOf when I have some classes that inherit from a base class and I have to compare what type of class the variable is



in the following code:

If TypeOf MainView Is Dx.DxGridView Then 

    With CType(MainView, Dx.DxGridView)

        .Columns(dc.ColumnName).DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric

        .Columns(dc.ColumnName).DisplayFormat.FormatString = "$ #,0.00"

    End With

ElseIf TypeOf MainView Is Dx.DxCardView Then 'DevExpress.XtraGrid.Views.Grid.GridView Then

    With CType(MainView, Dx.DxCardView)

        .Columns(dc.ColumnName).DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric

        .Columns(dc.ColumnName).DisplayFormat.FormatString = "$ #,0.00"

    End With

End If

to something like:

With CType(MainView, ThetypeOf(MainView))

.Columns(dc.ColumnName).DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric

.Columns(dc.ColumnName).DisplayFormat.FormatString = "$ #,0.00"

End With



MainView is a generic Class (devExpress BaseView) and I want to set a column property, but the generic class don't have a "column" and I have to use a ctype, I like to use a ctype (or something else) on the same object to know his type

I say, if mainview is a "cardview" or "gridView" when I put ctype(mainview,somefunctionthatgivemethetype(mainview).column work



the same to use with ctype(businesslayerVariable,getmyowntype(businesslayerVariable)).someproperty and ctype(businesslayerVariable,getmyowntype(businesslayerVariable)) give me myBO type



it is posible? thanks!



sorry if I cannot write my question correctly, I speak in spanish and it's hard to me
