Question

我有一个带有checkBox TemplateField的gridView控件。我试图根据选中的复选框控件从gridvie中删除记录，但不断收到错误

BC30456：'已选中'不是'复选框'的成员。

下面是我的button_click子程序，应该执行删除操作。

Protected Sub DeleteSelectedProducts_Click(sender As Object, e As EventArgs) Handles DeleteSelectedProducts.Click
    Try
        Dim atLeastOneRowDeleted As Boolean = False

        For Each row As GridViewRow In GridView1.Rows

            Dim cb As CheckBox = row.FindControl("ProductSelector")
            If cb IsNot Nothing AndAlso cb.Checked Then

                atLeastOneRowDeleted = True

                Dim productID As Integer = _
                    Convert.ToInt32(GridView1.DataKeys(row.RowIndex).Value)

                DeleteResults.Text &= String.Format( _
                    "This would have deleted ProductID {0}<br />", productID)

            End If
        Next
        DeleteResults.Visible = atLeastOneRowDeleted
    Catch ex As Exception

    End Try

End Sub

我猜这是WPF，因为WinForms CheckBox和ASP.NET CheckBox都有Checked属性。

对于WPF，您必须使用CheckBox.IsChecked：

If cb IsNot Nothing AndAlso cb.IsChecked Then
