Windows form host showing in Datagrid but not in DialogHost.

When using this DLL IPAddressControl` is made for forms in WPF like

<TextBlock Style="{StaticResource MaterialDesignDisplay1TextBlock}" TextWrapping="Wrap" HorizontalAlignment="Center">Database servers</TextBlock> <WindowsFormsHost Width="120"> <ipBox:IPAddressControl /> </WindowsFormsHost>

It is showing correctly as

But while the same element , If I am using in Dialoghost it is not showing. ` <Button Command="{x:Static materialDesign:DialogHost.OpenDialogCommand}" Margin="0 20 0 0" Width="140" HorizontalAlignment="Right">Add New Server <Button.CommandParameter> <StackPanel Margin="16"> <TextBlock>Add a new Server</TextBlock>

                    <!--<WindowsFormsHost wpf:HintAssist.Hint="Server IP"   Height="27" Width="100">
                        <ipBox:IPAddressControl x:Name="IPAddress"   />
                    </WindowsFormsHost>-->
                    <StackPanel x:Name="ipStack">
                        <WindowsFormsHost Width="120">
                            <ipBox:IPAddressControl x:Name="IPAddresss"   />

                        </WindowsFormsHost>

                    </StackPanel>
                    <TextBox wpf:HintAssist.Hint="Notes" Style="{StaticResource MaterialDesignTextAreaTextBox}"                             
                       VerticalScrollBarVisibility="Auto"  Margin="0 15 0 0" FontSize="16" Grid.Row="2" MaxLength="500" Width="400"
                        VerticalAlignment="Top" Height="100" AcceptsReturn="True" TextWrapping="Wrap">
                        <TextBox.Text>
                            <Binding Path="Notes" UpdateSourceTrigger="PropertyChanged"> </Binding>
                        </TextBox.Text>
                    </TextBox>



                    <StackPanel Orientation="Horizontal" HorizontalAlignment="Right" >
                                <Button Style="{StaticResource MaterialDesignFlatButton}" IsDefault="True"                                            
                                        Command="{Binding AddnewCommand}"> Add </Button>
                                <Button Style="{StaticResource MaterialDesignFlatButton}" IsCancel="True" 
                                        Command="{x:Static materialDesign:DialogHost.CloseDialogCommand}">Cancel</Button>
                            </StackPanel>
                        </StackPanel>
                    </Button.CommandParameter>

                </Button>`

You’ll need to add the ResourceDictionary inside the DialogHost if it isn’t inside App.xaml.
