我遇到了AutoCompleteBox过滤问题.

它似乎正在重新修改前一个过滤器.

例如,我输入'A',它返回1项.我删除'A'并输入'Z',它应返回1项.

问题是它返回'A'过滤器加'Z'的结果,我删除'Z'并输入'S',它带回2个项目,现在它显示所有3个过滤器的结果.

难道我做错了什么？

stockTypes.Add(new StockTypeDTO() { Description = "Steel Coil", StockCode = "SC" });
stockTypes.Add(new StockTypeDTO() { Description = "Palletised Steel Coil", StockCode = "PS" });
stockTypes.Add(new StockTypeDTO() { Description = "ZZZZZ", StockCode = "ZZ" });


<input:AutoCompleteBox x:Name="testauto" FilterMode="Custom">
    <input:AutoCompleteBox.ItemTemplate>
        <DataTemplate>
            <StackPanel>
                <ContentPresenter Content="{Binding Description}" />
            </StackPanel>
        </DataTemplate>
    </input:AutoCompleteBox.ItemTemplate>
</input:AutoCompleteBox>

testauto.ItemsSource = this.StockTypes;

testauto.ItemFilter = (search, item) =>
{
    StockTypeDTO stockType = item as StockTypeDTO;

    if (stockType != null)
    {
        string filter = search.ToUpper(CultureInfo.InvariantCulture);
        return (stockType.StockCode.ToUpper(CultureInfo.InvariantCulture).Contains(filter)
        || stockType.Description.ToUpper(CultureInfo.InvariantCulture).Contains(filter)); …
