我正在尝试制作一个新的UserControl
(TextBox
选择焦点上的所有文字),但我无法从代码中更新.text。
我想要实现的目标是:
kolicinaTbox.text = "test"
我的自定义控件是:
<UserControl x:Class="SelectAllTbox"
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"
xmlns:local="clr-namespace:Demo"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<Grid>
<TextBox x:Name="textBox" HorizontalAlignment="Left" Height="23" TextWrapping="Wrap" Text="0" VerticalAlignment="Top" Width="120"/>
</Grid>
Public Class SelectAllTbox
Private Sub textBox_GotFocus(sender As Object, e As RoutedEventArgs) Handles textBox.GotFocus
textBox.SelectAll()
End Sub
End Class
这是我代码中的控件:
<demo:SelectAllTbox x:Name="kolicinaTbox" HorizontalAlignment="Left" Margin="82,152,0,0" VerticalAlignment="Top" Width="63"/>

将属性添加到UserControl
(SelectAllTbox
类),获取/设置Text
的{{1}}属性:
TextBox
然后,您可以使用此属性设置Public Property Text() As String
Get
Return textBox.Text
End Get
Set(ByVal value As String)
textBox.Text = value
End Set
End Property
的{{1}}属性:
Text
