WPF ComboBox & Text

索引サイト

多少「手抜き」のような気もするが、・・使い易ければ、まあ、それはそれで





<ComboBox Margin="5" Name="comboBox2" Grid.Column="1" Grid.ColumnSpan="2" Grid.Row="1" />

<ComboBox Margin="5" Name="comboBox1" IsTextSearchCaseSensitive="False" SelectionChanged="comboBox1_SelectionChanged" Grid.Column="1" Grid.Row="2" Grid.ColumnSpan="2" />

<TextBox Margin="7,7,40,7" Name="textBox1" Grid.Column="1" Grid.Row="2" Grid.ColumnSpan="2"

         Text="{Binding ElementName=comboBox1,Path=Text}" />

<TextBlock Margin="5" Name="textBlock1" Text="TextBlock" Background="Cyan" Grid.Column="1" Grid.Row="6" />

<Button Margin="5" Name="button1" Click="button1_Click" Grid.Column="2" Grid.Row="6" Content="AddItem" />





int z_selectedIndex;

private void button1_Click(object sender, RoutedEventArgs e)

{

    comboBox1.Items.Add("111111111");

    comboBox1.Items.Add("222222222");

    comboBox1.Items.Add("333333333");

    comboBox1.Items.Add("444444444");

    comboBox1.Items.Add("555555555");

}

private void comboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

    z_selectedIndex = comboBox1.SelectedIndex;

    textBlock1.Text = "index:" + z_selectedIndex;

}
