Question

如何將TextBox和ComboBox中的用戶輸入值插入到DataGrid中？

當我們點擊保存按鈕，我已經這樣做了

在我Xmal位：

<Grid Margin="10,10,12,12"> 
      <DataGrid Name="customerDataGrid" CanUserAddRows="True" CanUserDeleteRows="True" Margin="34,56,237,73" AlternatingRowBackground="{x:Null}" MinRowHeight="10"></DataGrid> 
      <TextBlock Height="16" HorizontalAlignment="Left" Margin="554,110,0,0" Name="textBlock1" Text="Equipment" VerticalAlignment="Top" /> 
      <TextBlock Height="15" HorizontalAlignment="Left" Margin="554,137,0,0" Name="textBlock2" Text="ID" VerticalAlignment="Top" /> 
      <TextBlock Height="15" HorizontalAlignment="Left" Margin="554,163,0,0" Name="textBlock3" Text="Start Date" VerticalAlignment="Top" /> 
      <TextBlock Height="16" HorizontalAlignment="Left" Margin="554,187,0,0" Name="textBlock4" Text="End Date" VerticalAlignment="Top" /> 
      <TextBlock Height="16" HorizontalAlignment="Left" Margin="554,211,0,0" Name="textBlock5" Text="Requsted By" VerticalAlignment="Top" /> 
      <TextBlock Height="16" HorizontalAlignment="Left" Margin="554,233,0,0" Name="textBlock6" Text="Purpose" VerticalAlignment="Top" /> 
      <TextBlock Height="17" HorizontalAlignment="Left" Margin="568,56,0,0" Name="textBlock7" Text="ADD Maintainence Shedule" VerticalAlignment="Top" FontWeight="Bold" /> 
      <ComboBox Height="21" HorizontalAlignment="Left" Margin="617,110,0,0" Name="comboBox1" VerticalAlignment="Top" Width="99"> 
       <ComboBoxItem Content="LA"/> 
       <ComboBoxItem Content="CVT"/> 
       <ComboBoxItem Content="Isolator"/> 
       <ComboBoxItem Content="WT"/> 
       <ComboBoxItem Content="ICT"/> 
       <ComboBoxItem Content="CT"/> 
       <ComboBoxItem Content="PT"/> 
       <ComboBoxItem Content="E/S"/> 
       <ComboBoxItem Content="CB"/> 
       <ComboBoxItem Content="BUS" /> 
       <ComboBoxItem Content="CAP" /> 
      </ComboBox> 
      <ComboBox Height="21" HorizontalAlignment="Left" Margin="618,133,0,0" Name="comboBox2" VerticalAlignment="Top" Width="99"> 
       <ComboBoxItem Content="29A/00"/> 
       <ComboBoxItem Content="29B/00"/> 
       <ComboBoxItem Content="30A/03"/> 
       <ComboBoxItem Content="45B/50"/> 
       <ComboBoxItem Content="39A/00"/> 
       <ComboBoxItem Content="59A/00"/> 
          </ComboBox> 
      <DatePicker Height="21" HorizontalAlignment="Left" Margin="618,157,0,0" Name="datePicker1" VerticalAlignment="Top" Width="99" /> 
      <DatePicker Height="21" HorizontalAlignment="Left" Margin="618,0,0,251" Name="datePicker2" VerticalAlignment="Bottom" Width="99" /> 
      <TextBox Height="21" Margin="618,208,51,0" Name="textBox1" VerticalAlignment="Top" /> 
      <TextBox Height="21" Margin="618,231,51,0" Name="textBox2" VerticalAlignment="Top" /> 
      <Button Content="Save" Height="23" HorizontalAlignment="Left" Margin="612,270,0,0" Name="button1" VerticalAlignment="Top" Width="75" /> 
      <TextBlock Height="16" HorizontalAlignment="Left" Margin="554,85,0,0" Name="textBlock8" Text="BAY" VerticalAlignment="Top" /> 
      <ComboBox Height="21" HorizontalAlignment="Left" Margin="617,85,0,0" Name="comboBox3" VerticalAlignment="Top" Width="99"> 
       <ComboBoxItem Content="Kolhapur 1" /> 
       <ComboBoxItem Content="Kolhapur 2" /> 
       <ComboBoxItem Content="Kolhapur 3" /> 
       <ComboBoxItem Content="Kolhapur 4" /> 
       <ComboBoxItem Content="Vita 1" /> 
       <ComboBoxItem Content="Vita 2" /> 
       <ComboBoxItem Content="Karad 1" /> 
       <ComboBoxItem Content="Karad 2" /> 
       <ComboBoxItem Content="Miraj" /> 
       <ComboBoxItem Content="Pophali" /> 
       <ComboBoxItem Content="Pedambe" /> 
       <ComboBoxItem Content="Peth" /> 
       <ComboBoxItem Content="Koyana 1" /> 
       <ComboBoxItem Content="Koyana 2" /> 
       <ComboBoxItem Content="Lonikand" /> 
       <ComboBoxItem Content="Lamboti" /> 
      </ComboBox> 
     </Grid> 

在我Xmal.cs：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Windows; 
using System.Windows.Controls; 
using System.Windows.Data; 
using System.Windows.Documents; 
using System.Windows.Input; 
using System.Windows.Media; 
using System.Windows.Media.Imaging; 
using System.Windows.Shapes; 

namespace WpfApplication3 
{ 
    /// <summary> 
    /// Interaction logic for Window1.xaml 
    /// </summary> 
    public partial class Window1 : Window 
    { 
     public Window1() 
     { 
      InitializeComponent(); 
      customerDataGrid.ItemsSource = LoadCollectionData(); 
     } 
    public List<Customer> LoadCollectionData() 
     { 
      List<Customer> customer = new List<Customer>(); 

    customer.Add(new Customer() 
      { 
       Bay = "Kolhapur 1", 
       Euqipment = "JKL", 
       ID = "JKL", 
       Startmdy = new Calendar(), 
       Endmdy = new Calendar(), 
       Purpose = "Oiling.", 
       Requestedby = "Ashish.", 
      }); 
      return customer; 
     } 
    } 
public class Customer 
    { 
     public string Bay { get; set; } 
     public string Euqipment { get; set; } 
     public string ID { get; set; } 
     public Calendar Startmdy { get; set; } 
     public Calendar Endmdy { get; set; } 
     public string Purpose { get; set; } 
     public string Requestedby { get; set; } 

    } 
} 

我已經嘗試了很多方法，但他們沒有工作。任何幫助或一些參考將做。

Answer 1

創建一個集合來表示數據網格的每一行。您將使用上下文...（客戶端）

循環遍歷數據網格中的記錄並找到每一行的文本框 - 選取該值並添加到您的集合中。

Answer 2

您的XAML已關閉。它缺少將DataGrid中的控件連接到ItemsSource中的對象的數據綁定。

首先，不要在DataGrid上設置ItemsSource。請將其DataContext改爲客戶列表。然後，通過結合設置ItemsSource：

<DataGrid ItemsSource="{Binding}" ... 

爲了您的文本框，在Text屬性綁定到項目的屬性：

<TextBox Text="{Binding PropertyName, Mode=TwoWay}" ... /> 

爲了您的組合框，該SelectedValue屬性綁定到在屬性該項目：

<ComboBox SelectedValue="{Binding PropertyName, Mode=TwoWay}" ... />
