IsEnabled property not inheriting parent control value

[Michael]

I have a RadComboBox in a UserControl.
When I set the UserControl IsEnabled to false the combo box is still enabled.

Here's my XAML:

<cc:DesignTimeSafeControl x:Class="CustomControls.VendorCombo"
                          xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                        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:cc="clr-namespace:CustomControls"
                          IsEnabled="False"
                        mc:Ignorable="d" Loaded="UserControl_Loaded">

    <telerik:RadComboBox x:Name="VendorsBox" DisplayMemberPath="Name" SelectionChanged="VendorsBox_SelectionChanged" />
</cc:DesignTimeSafeControl>

DesignTimeSafeControl is derived from UserControl and simply adds a IsDesignTime property.  It contains no other code.

If I put the IsEnabled onto the RadComboBox tag, it works fine.
I'm doing it this way because I want to set the IsEnabled on the UserControl's parent form.
Am I doing something wrong here?

Thank you

Hi Michael,

Thank you for contacting us.

I can suggest you to bind the IsEnabled property of the ComboBox to the UserControl. In that way when you set the IsEnabled property of the UserControl, it will be also set to the ComboBox.

Hope this information helps. If you have further questions please let us know.

Best wishes,
