I have an user control:
<UserControl x:Class="WpfApplication2.Control1"
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:WpfApplication2"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<Grid>
<StackPanel Orientation="Horizontal" Name="StackPanelInsideUserControl">
<Label />
<TextBox Name="TextBoxInsideUserControl" Text="Initial Text" />
<Button Content="OK" />
</StackPanel>
</Grid>
And I'm trying to bind to the Text property of the TextBoxInsideUserControl TextBox from a its parent like in:
<Window x:Class="WpfApplication2.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication2"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<local:Control1 StackPanelInsideUserControl.TextBoxInsideUserControl.Text="{Binding SomeText}" />
</Grid>
How can I achieve that? Does xaml allow us to do that?
As requested, the comment as answer:
No, not really. You should define a dependency property on that UserControl
, bind that to the Text of the TextBox
. Then you can access the text outside of the UserControl via that dependency property.
