我正在以編程方式創建一個組合框，但我不知道如何使用 C# 添加虛擬化堆疊面板。
C＃
ComboBox newCombo = new ComboBox();
newCombo.IsEditable = true;
newCombo.DisplayMemberPath = "DisplayName";
newCombo.SelectedValuePath = "Value";
newCombo.SelectedValue = "Value";
XAML
<ComboBox Grid.Row="0" Grid.Column="1" x:Name="cbOrigin" Grid.ColumnSpan="2" IsEditable="True"
DisplayMemberPath="DisplayName"
SelectedValuePath="Value"
SelectedValue="{Binding Path=Value}" >
<ComboBox.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel />
</ItemsPanelTemplate>
</ComboBox.ItemsPanel>
</ComboBox>
uj5u.com熱心網友回復：
也許是這樣的：
ComboBox newCombo = new ComboBox();
newCombo.IsEditable = true;
newCombo.DisplayMemberPath = "DisplayName";
newCombo.SelectedValuePath = "Value";
newCombo.SelectedValue = "Value";
newCombo.ItemsPanel = new ItemsPanelTemplate(new
FrameworkElementFactory(typeof(VirtualizingStackPanel)));
