重写combobox模板,实现支持过滤的combobox

先看效果图

客户提出需求后,首选在百度查找可靠方案

看了几个,效果都不理想,

大多是把isEditNable设置成true,IsTextSearchNable设置成false

再对itemsSource的集合.where或findAll  过滤后重新赋值

但是这样会有很多交互细节变得很坑 爹

翻到墙外看了一下  又看到他的实现方法,在dropDownOper事件里 对 combobox.items.Filter 传入委托,过滤方法写在委托里

在下拉框出现时 就会过滤,这里交互细节还是不够友好, 输入文本  下拉框不会自己出现, 选中时  首次输入无效..

但是看到这里已经有思路了,于是开时手写思路,重写combobox样式后  在下拉框的popup控件里 加入一个搜索用的textbox,combobox isEditAble 和 istextsearchAble 都设置为false

在搜索文本框的textChanged事件里写filter 委托 具体如下,如此解决..  xaml代码太多了放最后面,其实看完这些文字,有思路后 下面这些代码都不重要了

        private void ComboBox_TextChanged(object sender, TextChangedEventArgs e)
        {
            TextBox textBox = e.OriginalSource as TextBox;

            ComboBox cbo = textBox.TemplatedParent as ComboBox;
            cbo.Items.Filter = null;
            cbo.Items.Filter += obj =>
            {
                bool result = false;
                var t = obj.GetType();
                var p = t.GetProperty(this.DisplayMemberPath);
                var text = (p.GetValue(obj) ?? "").ToString();
                if (text == null)
                {

                }
                else
                {
                    result = text.Contains(textBox.Text);
                }
                return result;
            };
        }
