示例1: PerformDataBinding
Protected Overrides Sub PerformDataBinding(ByVal retrievedData As IEnumerable)
MyBase.PerformDataBinding(retrievedData)
' If the data is retrieved from an IDataSource as an IEnumerable
' collection, attempt to bind its values to a set of TextBox controls.
If Not (retrievedData Is Nothing) Then
Dim dataItem As Object
For Each dataItem In retrievedData
Dim box As New TextBox()
' The dataItem is not just a string, but potentially
' a System.Data.DataRowView or some other container.
' If DataTextField is set, use it to determine which
' field to render. Otherwise, use the first field.
If DataTextField.Length > 0 Then
box.Text = DataBinder.GetPropertyValue( _
dataItem, DataTextField, Nothing)
Else
Dim props As PropertyDescriptorCollection = _
TypeDescriptor.GetProperties(dataItem)
' Set the "default" value of the TextBox.
box.Text = String.Empty
' Set the true data-bound value of the TextBox,
' if possible.
If props.Count >= 1 Then
If props(0).GetValue(dataItem) IsNot Nothing Then
box.Text = props(0).GetValue(dataItem).ToString()
End If
End If
