    <p>Just FYI, not sure if it'll fix anything, but your Invoke method can be simplified. This also removes the need for that delegate (possibly leading to a fix?):</p> <pre><code>dgv.BeginInvoke(new MethodInvoker(delegate() { PopulateReadOnlyGrid(dgv, gridLines, columns); })); </code></pre> <p>Your code runs fine for me when I paste it in a form (after commenting out your GridUtils stuff). I even call the method both from the gui thread and the non-gui thread. I tried it in 3.5 and 2.0. Works fine.... (!?)</p> <p>Try this code:</p> <pre><code>using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Reflection; using System.Threading; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private delegate void PROG_Delegate&lt;TGridLine&gt;(Control dgv, IEnumerable&lt;TGridLine&gt; gridLines, string[] columns); public static void PopulateReadOnlyGrid&lt;TGridLine&gt;(Control dgv, IEnumerable&lt;TGridLine&gt; gridLines, string[] columns) { if (dgv.InvokeRequired) { dgv.BeginInvoke ( new PROG_Delegate&lt;TGridLine&gt;(PopulateReadOnlyGrid&lt;TGridLine&gt;), new object[] { dgv, gridLines, columns } ); return; } MessageBox.Show("hi"); //GridUtils.StatePreserver statePreserver = new GridUtils.StatePreserver(dgv); //System.Data.DataTable dt = CollectionHelper.ConvertToDataTable&lt;TGridLine&gt;((gridLines)); //dgv.DataSource = dt; //dgv.DataMember = ""; //dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells; //GridUtils.OrderColumns&lt;TGridLine&gt;(dgv, columns); //statePreserver.RestoreState(); //dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None; } private void button1_Click(object sender, EventArgs e) { PopulateReadOnlyGrid(this, new int[] { 1, 2, 3 }, new string[] { "a" }); ThreadPool.QueueUserWorkItem(new WaitCallback((a) =&gt; { PopulateReadOnlyGrid(this, new int[] { 1, 2, 3 }, new string[] { "a" }); })); } } } </code></pre>

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.
