WPF组合框搜索项目 [英] WPF combobox search item
问题描述
有什么办法来控制间隔,当通过按键选择在组合框中的项目所使用的大小。例如。一个COMBOX包含{12,2}:
Is there any way to control the size of the interval, that is used when selected an item in a combobox via keystrokes. E.g. a combox contains {"12,"2}:
推1并迅速2.选择列表中的第一项。 推1,等待几秒钟,推2.选择第二项。
Pushing 1 and quickly 2. Selects the first item in the list. Pushing 1, wait a few seconds, push 2. Selects the second item.
我想控制此间隔中,使得壳体2更可能选择 第一个项目。
I would like to control this interval, such that case 2 is more likely to select the first item..
问候, 弗雷德里克
推荐答案
此行为是由私有财产支配,我怀疑,你可以改变它。
This behavior is governed by a private property, i doubt that you can change it.
// System.Windows.Controls.TextSearch
private TimeSpan TimeOut
{
get
{
return TimeSpan.FromMilliseconds((double)(SafeNativeMethods.GetDoubleClickTime() * 2));
}
}
正如你可以看到这实际上是依赖于系统的DoubleClick时。
As you can see this is actually dependent on the system's Doubleclick-Time.
