我已經建立了WPF有幾個列表框和添加按鈕:到選擇列表框添加項按鈕點擊
<Window x:Class="QuickSlide_2._0.Window1"
x:Name="load_style"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:self="clr-namespace:QuickSlide_2._0"
xmlns:e="http://schemas.microsoft.com/expression/2010/interactivity"
Title="Load_style" Height="300" Width="300" MinHeight="720" MinWidth="1280" WindowStyle="None" AllowsTransparency="True" Background="#B0000000" AllowDrop="True" WindowStartupLocation="CenterScreen" ShowInTaskbar="False">
<Grid>
<Rectangle Height="720" HorizontalAlignment="Left" Name="rectangle1" Stroke="#00000000" VerticalAlignment="Top" Width="1280" MinHeight="320" MinWidth="380" Fill="DarkGray"/>
<ListBox Height="241" HorizontalAlignment="Left" Margin="502,371,0,0" Name="Presentation_slide_items" VerticalAlignment="Top" Width="199" />
<ListBox Name="subjects_list" Margin="74,154,1039,171" ItemsSource="{Binding ElementName=styles_list, Path=SelectedItem.subjects}"/>
<ListBox Name="sub_subjects_list" Margin="264,154,849,171" ItemsSource="{Binding ElementName=subjects_list, Path=SelectedItem.sub_subjects}"/>
<ComboBox x:Name="styles_list" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Margin="74,112,0,0"/>
<ListBox Name="user_inputs" Margin="502,154,565,421" ItemsSource="{Binding ElementName=sub_subjects_list, Path=SelectedItem.possible_input, Mode=TwoWay}" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBox Name="TextBoxList" Text="{Binding input}" BorderThickness="0" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Button x:Name="button_add_input" Content="Add" HorizontalAlignment="Left" Margin="502,279,0,0" VerticalAlignment="Top" Width="106" Command="{Binding ElementName=sub_subjects_list.add_input} />
</Grid>
現在我想的更多的USER_INPUT在user_inputs列表框中添加到列表當點擊按鈕「button_add_input」時。我一直在尋找,它看起來像使用按鈕的「命令」選項可能是要走的路。 這是我的班「sub_subject」
public class sub_subject
{
public string short_name { get; set; }
public string name { get; set; }
public bool read_from_db { get; set; }
public string table_name { get; set; }
//public ObservableCollection<string> possible_input { get; set; }
public ObservableCollection<possible_input> possible_input { get; set; }
public sub_subject(string name)
{
this.name = name;
possible_input = new ObservableCollection<possible_input>();
//possible_input = new ObservableCollection<string>();
}
public override string ToString()
{
return this.name;
}
public void add_input()
{
possible_input input = new possible_input();
input.input = "";
possible_input.Add(input);
}
}
我想我可以添加一個功能,增加了一個possible_input到的ObservableCollection類並調用按鈕的命令這一功能。但我無法弄清楚如何設置正確的命令。有什麼建議麼?
感謝Niels的反應。這看起來像要走的路,會試一試! –
