我已經通過編程生成了包含標籤和文本框的網格。代碼顯示如下xamarin格式 - 在網格中獲取文本框的值
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);
}
我希望在每個行的文本框中獲取值?請幫忙!
如何知道位置r和c,因爲我不知道行索引。我面臨另一個問題。我希望將用戶在文本框中輸入的數據更新回數據庫。我不知道如何才能知道文本框中的數據屬於哪個ID。你有什麼想法如何確認身份證屬於同一行的文本框? –
