SL4 AutoCompleteBox重复筛选结果的问题 [英] SL4 AutoCompleteBox repeating filter results issue

问题描述

我在与AutoCompleteBox过滤的问题。

这似乎是rembering以前的过滤器。

例如我'A'类型，并将其返回1项。我删除了A，并输入'Z'，这应该返回1项。

问题是，它从'A'过滤器+'Z返回结果'，我删除了'Z'和式'S'这带回2项，现在会显示所有3对结果进行过滤。

我是不是做错了什么？

  stockTypes.Add（新StockTypeDTO（）{说明=钢卷，StockCode =SC}）; 
 stockTypes.Add（新StockTypeDTO（）{说明=货盘钢卷，StockCode =PS}）; 
 stockTypes.Add（新StockTypeDTO（）{说明=ZZZZZ，StockCode =ZZ}）; 
 
 
<输入：AutoCompleteBox X：NAME =testautoFILTERMODE =自定义> 
<输入：AutoCompleteBox.ItemTemplate> 
<&DataTemplate的GT; 
<&StackPanel的GT; 
< ContentPresenter CONTENT ={绑定描述}/> 
< / StackPanel的> 
< / DataTemplate中> 
< /输入：AutoCompleteBox.ItemTemplate> 
< /输入：AutoCompleteBox> 
 
 testauto.ItemsSource = this.StockTypes; 
 
 testauto.ItemFilter =（搜索项）=> 
 {
 StockTypeDTO stockType =项目作为StockTypeDTO; 
 
如果（stockType！= NULL）
 {
字符串过滤器= search.ToUpper（CultureInfo.InvariantCulture）; 
回报率（stockType.StockCode.ToUpper（CultureInfo.InvariantCulture）。载有（过滤器）
 || stockType.Description.ToUpper（CultureInfo.InvariantCulture）。载有（过滤器））; 
} 
 
返回FALSE; 
}; 
  

解决方案

此外，以前的结果显示，而是像对待他们是不存在的吧？我的意思是，他们选择不改变autocompletebox的价值？
我有同样的问题，改变了样式之后得到了它。在我的情况是因为ListBox的风格。如果你正在使用的列表框自定义样式，请尝试删除它和放大器;使用默认的样式。

I'm having an issue with the AutoCompleteBox filtering.

It seems to be rembering the previous filter.

For example I type in 'A' and it returns 1 item. I delete the 'A' and type in 'Z' which should return 1 item.

The problem is it returns the results from the 'A' filter plus the 'Z', I delete 'Z' and type 'S' which brings back 2 items and it now displays the results from all 3 filters.

Am I doing something wrong?

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));
    }

    return false;
};

解决方案

Also, the previous results are shown, but treated like they are non-existent right? I mean, selecting them don't change the autocompletebox's value? I'm having the same issue, got it after changing the style. In my situation it's because of ListBox's style. If you're using a custom style for listbox, try removing it & use the default style.
