vb.net - Load 事件中的控制流，VB.NET 桌面

Question

我的对话框上有这个代码：

Private Sub DAddSupplier_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    Dim objProveedores As New AR.CMP.ControlCatalogo()
    Dim dvClases, dvEstados As DataView

    dvClases = objProveedores.ListarClasesProveedor()

    If dvClases IsNot Nothing AndAlso dvClases.Count > 0 Then

        For i As Integer = 0 To dvClases.Count
            cmbClase.Items.Add(dvClases(i)("Class"))
        Next

    End If
    'reach until here the debugger 
    dvEstados = objProveedores.ListarEstadosProveedor()

    If dvEstados IsNot Nothing AndAlso dvEstados.Count > 0 Then

        For j As Integer = 0 To dvEstados.Count
            cmbEstado.Items.Add(dvEstados(j)("Name"))
        Next

    End If

End Sub

但只有到达第一个代码块，除非第一个被评论，否则它会被忽略，为什么会出现这种行为？

只需将它放在initializationComponent调用之后，它就会工作
