ボタン上Grid.Row依存関係プロパティを設定する必要があります。
XAML
<Window x:Class="WpfApplication1.MainWindow" [...] Loaded="Window_Loaded">
<Grid Name="grdMain">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
</Grid>
</Window>
C#
using System;
using System.Windows;
using System.Windows.Controls;
namespace WpfApplication1
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
void Window_Loaded(object sender, RoutedEventArgs e)
{
//creating the button
Button b = new Button() { Content = "Click me!" };
//when clicked, it'll move to another row
b.Click += (s, ea) => ChangeButtonRow(s as Button);
//adding the button to the grid
grdMain.Children.Add(b);
//calling the row changing method for the 1st time, so the button will appear in a random row
ChangeButtonRow(b);
}
void ChangeButtonRow(Button b)
{
//setting the Grid.Row dep. prop. to a number that's a valid row index
b.SetValue(Grid.RowProperty, new Random().Next(0, grdMain.RowDefinitions.Count));
}
}
}
私はこのことができます願っています。 :)
