Comentários

The BeforeAddDataBoundRow evento ocorre antes de uma nova linha é adicionada a uma fonte de dados vinculada a um ListObject.

Exemplos

O exemplo de código a seguir cria um DataTable e um ListObjecte vincula o ListObject para o DataTable. Em seguida, ele cria um BeforeAddDataBoundRow manipulador de eventos que cancela a adição de nova linha. Para testar o evento, adicione manualmente uma nova linha à ListObject na folha 1.

Este exemplo é para uma personalização em nível de documento.

WithEvents BeforeAddDataBoundRowList As _
    Microsoft.Office.Tools.Excel.ListObject
Private Sub ListObject_BeforeAddDataBoundRow()
    ' Create a new DataSet and DataTable.
    Dim ds As New DataSet()
    Dim dt As DataTable = ds.Tables.Add("Customers")
    dt.Columns.Add(New DataColumn("LastName"))
    dt.Columns.Add(New DataColumn("FirstName"))

    ' Add a new row to the DataTable.
    Dim dr As DataRow = dt.NewRow()
    dr("LastName") = "Chan"
    dr("FirstName") = "Gareth"
    dt.Rows.Add(dr)

    ' Create a list object.
    BeforeAddDataBoundRowList = _
        Me.Controls.AddListObject(Me.Range("A1"), _
