ComboBox cmb = (ComboBox)sender;
int izbranIndex = cmb.SelectedIndex;
if (izbranIndex == 1)
{
lvDataBinding.Items.Clear();
}
//lvDataBinding.Items.Clear();
}
我想这样做,当我点击第一个组合框时,第一个数组中的字符串会被添加到listview中。但由于没有发生任何事情,因此缺少某些东西。 (Items.Clear仅用于测试,我也将使用它来清除我在WPF中定义的先前listviewitems)。提前谢谢!

尝试使用SelectionChanged
事件;然后遍历数组并将项添加到列表视图中。
if(izbranIndex == 1){
foreach (string item in izbira1){
listview.Items.Add(item);
}
}

ComboBox cmb = (ComboBox)sender;
cmb.SelectionChanged += cmbx_SelectionChanged;
void cmbx_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
MessageBox.Show(string.Format("Index has been changed {0}", yourcomobobox.SelectedIndex));
if(yourcomobobox.SelectedIndex==1)
{
listview.Items.Clear();
foreach (string item in izbira1){
listview.Items.Add(new ListViewItem(item));
}
}
}

您可以将ItemsSource
的{{1}}属性设置为ListView
。尝试处理ComboBox的string[]
事件,如下所示:
SelectionChanged
