如何在数据网格 (WPF) 中添加文本框的特定值

Question

我有 5 个文本框和一个按钮，我想要的是在单击按钮时在数据网格中显示 5 个文本框值中的 4 个。我是新用户，所以无法附上界面图片。

我的文本框命名如下：

IDTextbox, titleText, QuantityTextbox, PriceTextbox, BrandTextbox

我的按钮名为AddButton。

当我点击AddButton时，来自titleText、QuantityTextbox、PriceTextbox、BrandTextbox的值应该显示在dataGrid中。

我不想在数据网格中显示产品 ID，而是想要一个标题为“Total_price”的列。此列应显示 total_price 即 (quantity * price)

另外，我想在每次点击 AddButton 时添加值。

谢谢

使用此代码

<Grid>
<Grid.ColumnDefinitions>
    <ColumnDefinition />
    <ColumnDefinition />
</Grid.ColumnDefinitions>
<DataGrid Name="DataGrid" ItemsSource="{Binding YourDataCollection}" />
<Grid Grid.Column="1">
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition />
        <RowDefinition />
    </Grid.RowDefinitions>
    <TextBlock Grid.Row="0" Text="{Binding SelectedItem.Id, 
        ElementName=DataGrid}" />
    <TextBlock Grid.Row="1" Text="{Binding SelectedItem.Name, 
        ElementName=DataGrid}" />
    <TextBlock Grid.Row="2" Text="{Binding SelectedItem.BirthDate, 
        ElementName=DataGrid}" />
</Grid>

做一些类似的事情.....

<TextBox Name="IDTextbox" AcceptsReturn="True" TextWrapping="Wrap" SpellCheck.IsEnabled="True" Language="en-US" />
<TextBox Name="titleText" AcceptsReturn="True" TextWrapping="Wrap" SpellCheck.IsEnabled="True" Language="en-US" />
<TextBox Name="QuantityTextbox" AcceptsReturn="True" TextWrapping="Wrap" SpellCheck.IsEnabled="True" Language="en-US" />
<TextBox Name="PriceTextbox" AcceptsReturn="True" TextWrapping="Wrap" SpellCheck.IsEnabled="True" Language="en-US" />
<TextBox Name="BrandTextbox" AcceptsReturn="True" TextWrapping="Wrap" SpellCheck.IsEnabled="True" Language="en-US" />
<Button Content="Add new row" HorizontalAlignment="Left" Margin="0,10,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click"/>

<DataGrid AutoGenerateColumns="False" Name="DataGrid1" CanUserAddRows="True" ItemsSource="{Binding TestBinding}" Margin="0,50,0,0" >
            <DataGrid.Columns>
                <DataGridTextColumn Header="Brand" IsReadOnly="True" Binding="{Binding Path=Brand}" Width="50"></DataGridTextColumn>
                <DataGridTextColumn Header="Title" IsReadOnly="True"  Binding="{Binding Path=Title}" Width="130"></DataGridTextColumn>
                <DataGridTextColumn Header="Quantity" IsReadOnly="True"  Binding="{Binding Path=Quantity}" Width="130"></DataGridTextColumn>
                <DataGridTextColumn Header="Price" IsReadOnly="True" Binding="{Binding Path=Price}" Width="130"></DataGridTextColumn>
            </DataGrid.Columns>
        </DataGrid>
public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        var data = new Test { Brand= BrandTextbox.Text, Title= titleText.Text,
                Quantity = QuantityTextbox.Text, Price = PriceTextbox.Text };

        DataGridTest.Items.Add(data);
    }
}

public class Test
{
    public string Brand { get; set; }
    public string Title { get; set; }
    public string Price { get; set; }
    public string Quantity { get; set; }
}

在 Xaml 中

<StackPanel>
    <TextBox x:Name="txtID" Height="50"></TextBox>
    <TextBox x:Name="txtQuantity" Height="50"></TextBox>
    <TextBox x:Name="txtPrice" Height="50"></TextBox>
    <TextBox x:Name="txtBrand" Height="50"></TextBox>
    <TextBox x:Name="txtTitle" Height="50"></TextBox>
    <Button Click="Button_Click_1" Height="20">Click</Button>
    <DataGrid x:Name="gridTotal">

    </DataGrid>
</StackPanel>

在windows Loaded事件中

DataTable dt = new DataTable();
private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            try
            {

                if (!dt.Columns.Contains("Title"))
                {
                    dt.Columns.Add("Title");
                }
                if (!dt.Columns.Contains("Quantity"))
                {
                    dt.Columns.Add("Quantity");
                }
                if (!dt.Columns.Contains("Price"))
                {
                    dt.Columns.Add("Price");
                }
                if (!dt.Columns.Contains("Brand"))
                {
                    dt.Columns.Add("Brand");
                }
                if (!dt.Columns.Contains("Total"))
                {
                    dt.Columns.Add("Total");
                }

                gridTotal.ItemsSource = dt.DefaultView;

            }
            catch (Exception ec)
            {
                throw ec;
            }
        }

在按钮点击

 private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            DataRow dr = dt.NewRow();
            dr["Title"] = txtTitle.Text;
            dr["Quantity"] = txtQuantity.Text;
            dr["Price"] = txtPrice.Text;
            dr["Brand"] = txtBrand.Text;
            dr["Total"] = Convert.ToDouble(txtQuantity.Text) * Convert.ToDouble(txtPrice.Text);

            dt.Rows.Add(dr);
        }
