我正在WPF中创建一个UserControl,而UserControl的工作方式是当用户将鼠标移到控件上时,应该删除它的子控件,但我似乎没有找到Children属性或类似的东西。
XAML在这里:
<UserControl x:Class="myTextBox"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
Name="thisTextBox"
mc:Ignorable="d" d:DesignWidth="300" Height="57" MouseEnter="UserControl_MouseEnter_1" MouseLeave="UserControl_MouseLeave_1">
<TextBlock Name="TypeText" TextWrapping="NoWrap" Text="" />
</UserControl>
在代码中我需要做这样的事情才能让TextBlock消失:
private void UserControl_MouseEnter_1(object sender, MouseEventArgs e)
{
Children.Clear(); // There is no such thing as children here!!!
}
答案 0 :(得分:3)
UserControl的“子元素”包含在Content属性中。您可以将其设置为null
以删除内容。
private void UserControl_MouseEnter_1(object sender, MouseEventArgs e)
{
Content = null;
}
