    <p>I have:</p> <ol> <li>Created a Windows forms project.</li> <li>Created a UserControl to hold a WPF TextBox.</li> <li>Added a CustomDictionary to the TextBox's SpellCheck.</li> <li>Added the UserControl to my Windows Form.</li> </ol> <p>XAML is used to add the WPF textbox to the user control:</p> <pre><code>&lt;UserControl x:Class="TestElementHost.SpellBox" 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="248" d:DesignWidth="250"&gt; &lt;Grid&gt; &lt;TextBox Name="txtWPF" /&gt; &lt;/Grid&gt; &lt;/UserControl&gt; </code></pre> <p>Here is the form code (buttons added in the VS designer file):</p> <pre><code>using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace TestElementHost { public partial class Form1 : Form { private System.Windows.Forms.Integration.ElementHost elementHost1; private SpellBox spellBox1; public Form1() { InitializeComponent(); this.elementHost1 = new System.Windows.Forms.Integration.ElementHost(); this.spellBox1 = new TestElementHost.SpellBox(); this.elementHost1.Location = new System.Drawing.Point(27, 12); this.elementHost1.Name = "elementHost1"; this.elementHost1.Size = new System.Drawing.Size(269, 296); this.elementHost1.TabIndex = 0; this.elementHost1.Text = "elementHost1"; this.elementHost1.Child = this.spellBox1; this.Controls.Add(this.elementHost1); } private void Form1_Load(object sender, EventArgs e) { spellBox1.txtWPF.SpellCheck.IsEnabled = true; spellBox1.txtWPF.SpellCheck.CustomDictionaries.Add(new Uri(Application.StartupPath + @"\MyDictionary.lex")); } private void button1_Click(object sender, EventArgs e) { spellBox1.txtWPF.Text = "my bbad word."; // bbad is in the CustomDictionary } private void button2_Click(object sender, EventArgs e) { spellBox1.txtWPF.IsEnabled = false; spellBox1.txtWPF.IsEnabled = true; // spellBox1.txtWPF.SpellCheck.IsEnabled = false; // spellBox1.txtWPF.SpellCheck.IsEnabled = true; } } } </code></pre> <p>This works quite happily and words in the CustomDictionary are ignored, until I try changing the IsEnabled, IsReadOnly or the Visibility property. For example, set IsReadOnly to true then straight back to false again and suddenly words that are in the customdictionary are redlined.</p> <p>The way I am getting round this is to set SpellCheck.IsEnabled to false then back to true on consecutive lines when I need to allow users to edit text in the control. This seems to bring the customdictionary back into play.</p> <p>Has anyone else had this problem? Is this a bug or have I missed something?</p>

    3. COHm, ok, less chance of initialisation errors then :) Is SpellCheck set in the XAML a'la `<TextBox x:Name="txtBox" SpellCheck.IsEnabled="True" ...` or set later in code?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
