    <p>I'm studying delegates and simple threading, I tried it in a <code>ComboBox</code> control, and experimented in a <code>DataGridViewComboBoxColumn</code> (cause I thought it would be the same) but it seems there's no <code>Invoke</code> property for this kind.</p> <p><strong>How can I set DataGridViewComboBoxColumn properties in a thread?</strong><br> Please see my code, this works for setting the properties of a <code>ComboBox</code> control using a thread: </p> <pre><code> private delegate void DelegateSetProperties(DataTable dataSource, string valueMember, string displayMember); Thread thread1; DelegateSetProperties delegateSetProperties; private void Form1_Load(object sender, EventArgs e) { delegateSetProperties = new DelegateSetProperties(SetProperties); thread1 = new Thread(new ThreadStart(InitValues)); thread1.IsBackground = true; thread1.Start(); } private void SetProperties(DataTable dataSource, string valueMember, string displayMember) { comboBox1.DataSource = dataSource; comboBox1.ValueMember = valueMember; comboBox1.DisplayMember = displayMember; comboBox1.SelectedIndex = 0; //dataGridViewComboBoxColumn1.DataSource = dataSource; //dataGridViewComboBoxColumn1.DisplayMember = valueMember; //dataGridViewComboBoxColumn1.ValueMember = displayMember"; } void InitValues() { var dt = new DataTable { TableName = "CATEGORY", Columns = { {"CategoryCode", typeof(string)}, {"Name", typeof(string)}, } }; dt.Rows.Add("C1", "Category1"); dt.Rows.Add("C2", "Category2"); dt.Rows.Add("C3", "Category3"); // and so on... comboBox1.Invoke(delegateSetProperties, new object[] { dt, "CategoryCode", "Name" //dataGridViewComboBoxColumn1.Invoke(delegateSetEvents, new object[] { dt, "CategoryCode", "Name" }); }); } </code></pre> <p>Please help...thanks in advance.</p>

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.
