WPF combobox search item

问题

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}:

Pushing 1 and quickly 2. Selects the first item in the list. Pushing 1, wait a few seconds, push 2. Selects the second item.

I would like to control this interval, such that case 2 is more likely to select the first item..

Regards, Fredrik

回答1:

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));
    }
}

As you can see this is actually dependent on the system's Doubleclick-Time.
