问题描述
我有两个具有相同组合框项目(Apple& Orange)的WPF组合框(comboboxA,comboboxB)。让我们说在组合框A中选择Apple,然后Apple需要隐藏在comboxB中。如果我回到comboxA并选择橙色,苹果将可见,橙色需要隐藏。我如何实现使用C#?代码片段xaml:
< ComboBox Name =comboboxA>
< ComboBoxItem Content =AppleName =AppleA>< / ComboBoxItem>
< ComboBoxItem Content =OrangeName =OrangeA>< / ComboBoxItem>
< / ComboBox>
< ComboBox Name =comboboxB>
< ComboBoxItem Content =AppleName =AppleB>< / ComboBoxItem>
< ComboBoxItem Content =OrangeName =OrangeB>< / ComboBoxItem>
< / ComboBox>
解决方案
您可以使用sa_ddam213提到的方法,
private void comboboxA_SelectionChanged(object sender,SelectionChangedEventArgs e)
{
for(int i = 0; i {
if((ComboBoxItem)(comboboxB.Items [i])) .Content.ToString()==((ComboBoxItem)comboboxA.SelectedItem).Content.ToString())
{
(ComboBoxItem)(comboboxB.Items [i]))。 Windows.Visibility.Collapsed;
}
else
((ComboBoxItem)(comboboxB.Items [i]))。Visibility = System.Windows.Visibility.Visible;
}
}
i have 2 WPF comboboxes(comboboxA, comboboxB)with identical combobox item(Apple & Orange). Let say i select "Apple" in the comboboxA, then the "Apple" need to be hidden in the comboxB. If i go back to comboxA and select "Orange", "Apple" will be visible and "Orange" need to be hidden. How can i achieve that using C#?
code snippet for xaml:
<ComboBox Name="comboboxA" >
<ComboBoxItem Content="Apple" Name="AppleA"></ComboBoxItem>
<ComboBoxItem Content="Orange" Name="OrangeA"></ComboBoxItem>
</ComboBox>
<ComboBox Name="comboboxB" >
<ComboBoxItem Content="Apple" Name="AppleB"></ComboBoxItem>
<ComboBoxItem Content="Orange" Name="OrangeB"></ComboBoxItem>
</ComboBox>
解决方案
You can use the Method that sa_ddam213 mentioned, or you can just brute force it in the SelectionChanged Event like so.
private void comboboxA_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
for (int i = 0; i <= comboboxB.Items.Count -1; i++)
{
if (((ComboBoxItem)(comboboxB.Items[i])).Content.ToString() == ((ComboBoxItem)comboboxA.SelectedItem).Content.ToString())
{
((ComboBoxItem)(comboboxB.Items[i])).Visibility = System.Windows.Visibility.Collapsed;
}
else
((ComboBoxItem)(comboboxB.Items[i])).Visibility = System.Windows.Visibility.Visible;
}
}
