[英]AutoCompleteBox Selected on CTRL + N key event but not focused
I want to focus AutoCompleteBox when on UserControl CTRL + N key pressed. 我想在按UserControl CTRL + N键时将AutoCompleteBox聚焦。 I wrote Keyboard.Focus(CustomerSearch);
我写了Keyboard.Focus(CustomerSearch);
. 。 The problem is on pressing CTRL + N key, the AutoCompleteBox not focused but selected with dotted line as can seen in below image, 问题在于按下CTRL + N键时,AutoCompleteBox没有聚焦,而是用虚线选中,如下图所示,
<controls:AutoCompleteBox Name="CustomerSearch" IsTextCompletionEnabled="True" SelectedItem="{Binding Name, Mode=TwoWay}" Grid.Column="1" PreviewKeyDown="CustomerSearch_PreviewKeyDown" >
<controls:AutoCompleteBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Code}"/>
<TextBlock Text="{Binding Name}"/>
<TextBlock Text="{Binding Address}"/>
<TextBlock Text="{Binding Contact}"/>
</StackPanel>
</DataTemplate>
</controls:AutoCompleteBox.ItemTemplate>
</controls:AutoCompleteBox>
The Ctrol + N event: Ctrol + N事件:
private void UserControl_PreviewKeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.N && (Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control)
{
Keyboard.Focus(CustomerSearch);
}
}
You should focus the TextBox
in the AutoCompleteBox
: 您应该将TextBox
放在AutoCompleteBox
:
private void UserControl_PreviewKeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.N && (Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control)
{
TextBox textBox = CustomerSearch.Template.FindName("Text", CustomerSearch) as TextBox;
if (textBox != null)
Keyboard.Focus(textBox);
}
}
