我已经通过编程生成了包含标签和文本框的网格。代码显示如下xamarin格式 - 在网格中获取文本框的值
grid.Children.Add(new Label { Text = "ID", BackgroundColor = Color.Black, IsVisible = false, FontAttributes = FontAttributes.Bold, TextColor = Color.White, FontSize = Device.GetNamedSize(NamedSize.Small, typeof(Label)), }, 0, 1, 0, 1);
grid.Children.Add(new Label { Text = "Desc", BackgroundColor = Color.Black, FontAttributes = FontAttributes.Bold, TextColor = Color.White, FontSize = Device.GetNamedSize(NamedSize.Small, typeof(Label)), }, 1, 2, 0, 1);
grid.Children.Add(new Label { Text = "Qty", BackgroundColor = Color.Black, FontAttributes = FontAttributes.Bold, TextColor = Color.White, FontSize = Device.GetNamedSize(NamedSize.Small, typeof(Label)), }, 2, 3, 0, 1);
grid.Children.Add(new Label { Text = "Receive Qty", BackgroundColor = Color.Black, FontAttributes = FontAttributes.Bold, TextColor = Color.White, FontSize = Device.GetNamedSize(NamedSize.Small, typeof(Label)), }, 4, 6, 0, 1);
for (int i = 0; i < 10; i++)
{
sID = e.Result[i].ID.ToString();
sQty = e.Result[i].Qty.ToString();
sDesc = e.Result[i].DESC1.ToString();
if(e.Result[i].ReceivedQty.ToString() == "0")
{
sReceivedQty = sQty;
}
else
{
sReceivedQty = e.Result[i].ReceivedQty.ToString();
}
grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(1, GridUnitType.Auto) });
grid.Children.Add(new Label { Text = sID, IsVisible = false, BackgroundColor = Color.Gray, TextColor = Color.White, FontSize =
Device.GetNamedSize(NamedSize.Micro, typeof(Label)) }, 0, 1, i + 1, i + 2);
grid.Children.Add(new Label { Text = sDesc, BackgroundColor = Color.Gray, TextColor = Color.White, FontSize =
Device.GetNamedSize(NamedSize.Micro, typeof(Label)) }, 1 2, i + 1, i + 2);
grid.Children.Add(new Label { Text = sQty, BackgroundColor = Color.Gray, TextColor = Color.White, FontSize =
Device.GetNamedSize(NamedSize.Micro, typeof(Label)) }, 2, 3, i + 1, i + 2);
grid.Children.Add(new Entry { Text = sReceivedQty, TextColor = Color.White, FontSize = 10 }, 3, 4, i + 1, i + 2);
}
我希望在每个行的文本框中获取值?请帮忙!
如何知道位置r和c,因为我不知道行索引。我面临另一个问题。我希望将用户在文本框中输入的数据更新回数据库。我不知道如何才能知道文本框中的数据属于哪个ID。你有什么想法如何确认身份证属于同一行的文本框? –
