listboxitem

问题 I want to change the margin of the first item in the ListBox if SomeProperty value is 10, without code-behind. This is what I have so far: <ListBox x:Class="Windows.CustomList" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:Windows" mc:Ignorable="d" x:Name="MyList

问题 I know that: String test = "test"; ListBox.Items.Add(test); or String test = "test"; int index = 1; ListBox.Items.Insert(index, String); adds the String in a ListBox, but I want to insert ListBoxItem, how to? previously I learn that var contentToString = (String)ListBoxItem.Content; simply converts ListBoxItem to String, but I couldn't do the opposite to convert String to ListBoxItem 回答1: Try this: ListBoxItem itm = new ListBoxItem(); itm.Content = "some text"; listbox.Items.Add(itm); listbox

问题 I have added a DataTemplate to a ListBox class to bind my collection to: <ListBox x:Name="lstEmails" Height="259" Margin="12,0,12,41" Width="276" SelectionChanged="lstEmails_SelectionChanged"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <Label Visibility="Hidden" Content="{Binding ID}"></Label> <TextBox Width="200" Text="{Binding EmailAddress}"></TextBox> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> This does exactly what I want it to do.

问题 Is there a way to add some buttons to the selected ListBoxItem by adding these buttons to a style which is being used for the selected item? I didn't yet find a suitable style FMX uses to display the selected item. My goal is to have some buttons on the selected item with context based functionality.
