C# - Image From Datagrid view to picture box

I have datagrid view with a column type of image. I want to get the value from the datagrid to the picture box that I'm using. Here's my code located in my CellClick

byte[] image = (byte[])dgv_salesquotesummary.Rows[e.RowIndex].Cells[7].Value;
MemoryStream ms = new MemoryStream(image);
pb_productImage.Image = Image.FromStream(ms);

I got this error that says 

Additional information: Unable to cast object of type 'System.Drawing.Bitmap' to type 'System.Byte[]'.

Thank you in advance!

The error message shows a failure on casting Bitmap to byte[]. This means the cell Value is a Bitmap, which derive from Image. In simple types usually you can just use it immediately like this :

pb_productImage.Image = (Image) dgv_salesquotesummary.Rows[e.RowIndex].Cells[7].Value

However, since in this case the Image could be disposed at any time by your datagrid, it's prudent to clone the Image first, like :

pb_productImage.Image = (Image)(((Bitmap)dgv_salesquotesummary.Rows[e.RowIndex].Cells[7].Value).Clone())
