Code to retrieve image from database

Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles GridView1.SelectedIndexChanged

Try
If Not IsDBNull(GridView1.Rows(e.RowIndex).Cells("Qimage").Value) Then


'Get image data from gridview column.



''Initialize image variable
Dim newImage As Image
'Read image data into a memory stream
Using ms As New MemoryStream(ReadFile(GridView1.Rows(e.RowIndex).Cells("Qimage").Value), 0, ReadFile(GridView1.Rows(e.RowIndex).Cells("Qimage").Value).Length)
ms.Write(ReadFile(GridView1.Rows(e.RowIndex).Cells("Qimage").Value), 0, ReadFile(GridView1.Rows(e.RowIndex).Cells("Qimage").Value).Length)

'Set image variable value using memory stream.
newImage = Image.FromStream(ms, True)
End Using

'set picture
Image1.Image = newImage
End If

Catch ex As Exception
End Try


Private Function ReadFile(ByVal sPath As String) As Byte()
'Initialize byte array with a null value initially.
Dim data As Byte() = Nothing

'Use FileInfo object to get file size.
Dim fInfo As New FileInfo(sPath)
Dim numBytes As Long = fInfo.Length

'Open FileStream to read file
Dim fStream As New FileStream(sPath, FileMode.Open, FileAccess.Read)

'Use BinaryReader to read file stream into byte array.
Dim br As New BinaryReader(fStream)

'When you use BinaryReader, you need to supply number of bytes to read from file.
'In this case we want to read entire file. So supplying total number of bytes.
data = br.ReadBytes(CInt(numBytes))
Return data
End Function
On the click of "Select" in the gridview I need to get the Desired image in image control.

I tried this in Vb.net, on the Datagridview cell click event but that does not works here.

Can you help me in this?
