See more:

<Canvas>
    <wpfUCAllInOne:UC_TextBox Canvas.Left="100" Canvas.Top="100" Width="80" />
</Canvas>

This usercontrol (UC_TextBox) is set 100 to the left of the canvas.

<UserControl x:Class="UC_TextBox"
             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" 
             mc:Ignorable="d" 
             d:DesignHeight="100" d:DesignWidth="300">



</UserControl>

But how do I set this control 120 to the canvas IN the usercontrol. There is no parent control or something like it.

Why do you need to do this? It is the responsibility of the container to place the child elements not the other way around.

In the program, the controls are put in place. But I want to to this from the the database

So then you really want to do this from code like in solution 1 not the XAML.

Hi Quator,

Just move the control using Canvas static methods, for example on button click:

UserControl1.cs:

C#

/// <summary>
/// Interaction logic for UserControl1.xaml
/// </summary>
public partial class UserControl1 : UserControl
{
    public UserControl1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        Canvas.SetLeft(this, 120);
    }
}

UserControl.xaml:

XML

<UserControl x:Class="WpfApplication14.UserControl1"
             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" 
             mc:Ignorable="d" 
             d:DesignHeight="300" d:DesignWidth="300">
    <Grid removed="Aqua">
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
    </Grid>
</UserControl>

Best Regards,

Shai
