Today I encountered an issue with the WPF standard CombBox where if the bound ItemsSource (collection) of a ComboBox has changed the binding on the SelectedItem of the ComboBox will fail to update to the already properly set view model property. For
ComboBox值排序先是想通过冒泡排序,但是冒泡排序是int类型,又打算通过下标,进行字符串排序,然后想到了一个简单的办法……先存入ArrayList排序Sort清空ComboBox再遍历存入ComboBox很简单的几行代码搞定 ArrayList al =new ArrayList(); for (int i = 0; i < combobox.Items.Count; i++) { string a = combobox.Items[i].ToString(); al.Add(a);
POJO: class ComboBoxItem { string _text; string _value; public string Text { get { return _text; } set { _text = value; } } public string Value { get { return _value; } set { _value = value; } } public override String ToString() { return this.Value;
