示例1: BindTextBoxControl
Private Sub BindTextBoxControl()
Dim myDataSet As New DataSet()
' Insert code to populate the DataSet with tables, columns, and data.
' Creates a new Binding object.
Dim myBinding As New Binding("Text", myDataSet, _
"customers.custToOrders.OrderAmount")
' Adds event delegates for the Parse and Format events.
AddHandler myBinding.Parse, AddressOf CurrencyToDecimal
AddHandler myBinding.Format, AddressOf DecimalToCurrency
' Adds the new Binding to the BindingsCollection.
text1.DataBindings.Add(myBinding)
End Sub
Private Sub DecimalToCurrency(sender As Object, _
cevent As ConvertEventArgs)
' This method is the Format event handler. Whenever the
' control displays a new value, the value is converted from
' its native Decimal type to a string. The ToString method
' then formats the value as a Currency, by using the
' formatting character "c".
cevent.Value = CDec(cevent.Value).ToString("c")
End Sub
Private Sub CurrencyToDecimal(sender As Object, _
cevent As ConvertEventArgs)
' This method is the Parse event handler. The Parse event
' occurs whenever the displayed value changes. The static
' Parse method of the Decimal structure converts the
' string back to its native Decimal type.
cevent.Value = Decimal.Parse(cevent.Value.ToString(), _
NumberStyles.Currency, nothing)
End Sub
