    <p>If you want to show your images in the <code>DataGridViewImageColumn</code>, you have to set-up your data like this:</p> <pre><code>dt.Columns.Add("Picture", typeof(byte[])); var actualData = dt.AsEnumerable() .Select(row=&gt; { row.SetField&lt;byte[]&gt;("Picture", GetBytesFromImagePath(row.Field&lt;string&gt;("brandPic")); return row; }).CopyToDataTable(); actualData.Columns.Remove("brandPic"); dgv.DataSource = actualData; //Use this method to get byte[] data from the image path private byte[] GetBytesFromImagePath(string imagePath){ using(MemoryStream ms = new MemoryStream()){ Image img = Image.FromFile(imagePath); img.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); return ms.GetBuffer(); } } //Set-up Header Text dgv.Columns[0].HeaderText = "Brand Name"; dgv.Columns[1].HeaderText = "Brand Picture"; </code></pre> <p><strong>NOTE</strong>: You don't need to add columns to your <code>dgv</code> manually, just set the <code>DataSource</code> as in my code.</p> <p>If you save <code>URL</code> to images instead of <code>local filepath</code>, you can modify the code like this:</p> <pre><code>dt.Columns.Add("Picture", typeof(byte[])); System.Net.WebClient client = new System.Net.WebClient(); int i = 0; client.DownloadDataAsync(new Uri(dt.Rows[0].Field&lt;string&gt;("brandPic")), dt.Rows[0]); client.DownloadDataCompleted += (se, e) =&gt; { ((DataRow)e.UserState).SetField&lt;byte[]&gt;("Picture", e.Result); if(++i == dt.Rows.Count) return; client.DownloadDataAsync(new Uri(dt.Rows[i].Field&lt;string&gt;("brandPic")), dt.Rows[i]); }; dt.Columns.Remove("brandPic"); dgv.DataSource = dt; </code></pre>

    1. CO@user1592474 don't thank too soon, you just need to try the code and give some feedback so that I can improve the answer. I'm pretty sure it works. BTW, your code has many things wrong, you use a `DataGridViewImageColumn` but your `brandPic` seems to be `string` referring to image file paths or urls, you passed in the `Row index` into `.Cells[...]` which needs some `Column index` making your `IndexOutOfRangeException`, ... anyway your code is too messy and the solution is use a totally new code with new approach as posted in my answer.

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.
