When the image exists at the database , It shows correctly at pictureBox.
If the image doesn't exist, it shows error.

The Code is Here !

Private Sub gdCompany_CellClick_1(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles gdCompany.CellClick
      btnSave.Text = "ျပင္ရန္"
      picCompanyLogo.Visible = True
      txtCompanyName.Text = gdCompany.CurrentRow.Cells(1).Value.ToString()
      txtDescription.Text = gdCompany.CurrentRow.Cells(2).Value.ToString()
      txtPhoneNo.Text = gdCompany.CurrentRow.Cells(3).Value.ToString()
      txtFaxNo.Text = gdCompany.CurrentRow.Cells(4).Value.ToString()
      txtEmail.Text = gdCompany.CurrentRow.Cells(5).Value.ToString()
      txtWebsite.Text = gdCompany.CurrentRow.Cells(6).Value.ToString()
      ddlBankName.SelectedValue = Convert.ToInt32(gdCompany.CurrentRow.Cells(7).Value.ToString())
      ddlBankBranch.SelectedValue = Convert.ToInt32(gdCompany.CurrentRow.Cells(8).Value.ToString())
      txtBankAccountNo.Text = gdCompany.CurrentRow.Cells(9).Value.ToString()
      txtAddress.Text = gdCompany.CurrentRow.Cells(10).Value.ToString()
      Try
          'Get image data from gridview column.
          Dim imageData As Byte() = DirectCast(gdCompany.CurrentRow.Cells(15).Value, Byte())
          'Initialize image variable
          Dim newImage As Image
          'Read image data into a memory stream
          Using ms As New MemoryStream(imageData, 0, imageData.Length)
              ms.Write(imageData, 0, imageData.Length)
              'Set image variable value using memory stream.
              newImage = Image.FromStream(ms, True)
          End Using
          'set picture
          picCompanyLogo.Image = newImage
      Catch ex As Exception
          MessageBox.Show(ex.ToString())
          txtCompanyName.Focus()
      End Try
  End Sub
