datagridview Image Display vb.net MS Access - vb.net

Question

my code is to read the image file path in every row and display it in the datagridview "Image" Column.
.....
what's the problem with my code? please help me fix this.
UPDATE
this is the updated code but it displays nothing.
Dim dbdataset As New DataTable
Try
con.Open()
query = "Select * FROM [svfmemberlist]"
cmd = New OleDbCommand(query, con)
da.SelectCommand = cmd
da.Fill(dbdataset)
dgvSearch.RowTemplate.Height = 150
source.DataSource = dbdataset
dgvSearch.DataSource = source
Dim img As New DataGridViewImageColumn()
dgvSearch.Columns.Add(img)
img.HeaderText = "Image"
img.Name = "img"
img.ImageLayout = DataGridViewImageCellLayout.Zoom
dgvSearch.Columns("img").DataGridView.AutoGenerateColumns = False
dgvSearch.Columns("Name").AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill
dgvSearch.Columns("img").Width = 150
For Each row As DataGridViewRow In dgvSearch.Rows
If Not row.Cells("imgPath").FormattedValue.ToString = Nothing Then
Dim str As String = row.Cells("imgPath").FormattedValue.ToString
Dim inImg As Image = Image.FromFile(str)
row.Cells("img").Value = inImg
Else
img.Image = Nothing
End If
Next
con.Close()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try

The following example does not match how you are loading data and images but with a little effort will work within your current code.
I created two columns in the DataGridView via the IDE, one Text and one Image DataGridViewColumn.
The first line in form load sets ImageLayout, second line of code sets alignment to top-left for appearances. Next I set auto-size mode for all columns followed by setting the row height for each row.
Next (these lines are to load images from a folder one level below the app folder).
Setup the path to the images.
Add images using FileImageBytes function (which I would place into a separate class or code module but works just fine in your form).
Yes everything is hard-wired so it's easy to see how everything works.
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
CType(DataGridView1.Columns("PictureColumn"), DataGridViewImageColumn).ImageLayout = DataGridViewImageCellLayout.Normal
DataGridView1.Columns.Cast(Of DataGridViewColumn).Select(Function(col) col).ToList _
.ForEach(Sub(col) col.CellTemplate.Style.Alignment = DataGridViewContentAlignment.TopLeft)
DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells
DataGridView1.RowTemplate.Height = 222
Dim imagePath As String = IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Images")
DataGridView1.Rows.Add(New Object() {"Car1", FileImageBytes(IO.Path.Combine(imagePath, "Car1.bmp"))})
DataGridView1.Rows.Add(New Object() {"Car2", FileImageBytes(IO.Path.Combine(imagePath, "Car2.jpg"))})
End Sub
Public Function FileImageBytes(ByVal FileName As String) As Byte()
Dim fileStream As IO.FileStream = New IO.FileStream(FileName, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
Dim byteArray(CInt(fileStream.Length - 1)) As Byte
fileStream.Read(byteArray, 0, CInt(fileStream.Length))
Return byteArray
End Function
End Class
