Wie kann ich dafür sorgen, dass ein WPF-Kombinationsfeld die Breite seines breitesten Elements in XAML hat?
Ich weiß, wie man es im Code macht, aber kann das in XAML gemacht werden?
Window1.xaml:
<code><Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <ComboBox Name="ComboBox1" HorizontalAlignment="Left" VerticalAlignment="Top"> <ComboBoxItem>ComboBoxItem1</ComboBoxItem> <ComboBoxItem>ComboBoxItem2</ComboBoxItem> </ComboBox> </Grid> </Window> </code>
Window1.xaml.cs:
<code>using System.Windows; using System.Windows.Controls; namespace WpfApplication1 { public partial class Window1 : Window { public Window1() { InitializeComponent(); double width = 0; foreach (ComboBoxItem item in ComboBox1.Items) { item.Measure(new Size( double.PositiveInfinity, double.PositiveInfinity)); if (item.DesiredSize.Width > width) width = item.DesiredSize.Width; } ComboBox1.Measure(new Size( double.PositiveInfinity, double.PositiveInfinity)); ComboBox1.Width = ComboBox1.DesiredSize.Width + width; } } } </code>
