How to remove all ListBox items?
- by Nano HE
Hi, I created two RadioButton (Weight and Height). I will do switch between the two categories. But the they share the same ListBox Controllers (listBox1 and listBox2).
Is there any good method to clear all the ListBox items simpler? I didn't find the removeAll() for ListBox. I don't like my complex multi-lines style which I posted here.
private void Weight_Click(object sender, RoutedEventArgs e)
{
// switch between the radioButton "Weith" and "Height"
// Clear all the items first
listBox1.Items.Remove("foot");
listBox1.Items.Remove("inch");
listBox1.Items.Remove("meter");
listBox2.Items.Remove("foot");
listBox2.Items.Remove("inch");
listBox2.Items.Remove("meter");
// Add source units items for listBox1
listBox1.Items.Add("kilogram");
listBox1.Items.Add("pound");
// Add target units items for listBox2
listBox2.Items.Add("kilogram");
listBox2.Items.Add("pound");
}
private void Height_Click(object sender, RoutedEventArgs e)
{
// switch between the radioButton "Weith" and "Height"
// Clear all the items first
listBox1.Items.Remove("kilogram");
listBox1.Items.Remove("pound");
listBox2.Items.Remove("kilogram");
listBox2.Items.Remove("pound");
// Add source units items for listBox1
listBox1.Items.Add("foot");
listBox1.Items.Add("inch");
listBox1.Items.Add("meter");
// Add target units items for listBox2
listBox2.Items.Add("foot");
listBox2.Items.Add("inch");
listBox2.Items.Add("meter");
}
