私はXAMLでこれをやろうとしています:
TextBox tb = (TextBox)e.Item.FindControl("tvNote");
スクロール ビューアー内にテキスト ボックスがあり、その値を見つける必要があります。これが私のコードです:
<Grid x:Name="itemDetailGrid" Margin="0,60,0,50">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Image Grid.Row="1" Margin="0,0,20,0" Width="180" Height="180" Source="{Binding Image}" Stretch="UniformToFill" AutomationProperties.Name="{Binding Title}" Visibility="Collapsed" />
<StackPanel x:Name="itemDetailTitlePanel" Grid.Row="1" Grid.Column="1">
<TextBlock x:Name="itemTitle" Margin="0,-10,0,0" Text="{Binding Name}" Style="{StaticResource SubheaderTextStyle}"/>
<TextBlock x:Name="itemSubtitle" Margin="0,0,0,20" Text="{Binding Description}" Style="{StaticResource SubtitleTextStyle}"/>
<TextBlock Grid.Row="2" Grid.ColumnSpan="2" Margin="0,20,0,0" Text="{Binding Price, Mode=TwoWay,Converter={StaticResource PriceValueConverter}}" Style="{StaticResource BodyTextStyle}"/>
<TextBox x:Name="tvQuantity"/>
<TextBox x:Name="tvNotes"/>
<Button x:Name="btnAdd" Content="Add" Click="btnAdd_Click"/>
</StackPanel>
</Grid>
</ScrollViewer>
ボタン クリックを使用して、TV Note を見つけるにはどうすればよいですか? これが私のボタンクリックです:
public void btnAdd_Click(object sender, RoutedEventArgs e)
{
Button btnAdd = (Button)sender;
int quan = 0;
bool q = int.TryParse(tvQuantity.Text, out quan);
if (q == false)
{
MessageDialog messageDialog = new MessageDialog("Please enter a valid quantity.", "Quantity Invalid");
messageDialog.ShowAsync();
return;
}
//this causes an issue for items in an existing order
Product product = btnAdd.CommandParameter as Product;
IEnumerable<OrderDetail> query = App.CurrentOrder.OrderDetails.Where(a => a.Name == product.Name);
if (query.Count() == 0)
{
//insert order
Repository.AddOrderDetail(product.Name, product.Description, product.Price, quan, App.CurrentOrder.Id, tvNote.Text, product.Category);
MessageDialog messageDialog = new MessageDialog(product.Name + " has been successfully added to your order.", "Item Added");
messageDialog.ShowAsync();
messageDialog.Commands.Add(new UICommand("OK", new UICommandInvokedHandler(YesCommandInvokedHandler)));
}
else
{
OrderDetail orderDetail = btnAdd.CommandParameter as OrderDetail;
orderDetail.Quantity = quan;
orderDetail.OrderDetailNote = tvNote.Text;
Repository.UpdateOrderDetail(orderDetail.Id, orderDetail.Category, orderDetail.Description, orderDetail.Name, orderDetail.OrderDetailNote, orderDetail.OrderId, orderDetail.Price, quan);
MessageDialog messageDialog = new MessageDialog(orderDetail.Name + " has been successfully updated.", "Item Updated");
messageDialog.ShowAsync();
}
