Read shapefile Attributes to combobox in datagridview

[SigsterSal]

Hi
I am reading shapfile name to Columns and Attributes to combobox in datagridview Columns(2)
but I get Attributes from all shape to each combobox
don't separate each combobox with just Attributes from each file individually

 Dim tableNames As New List(Of String)()
        Dim openFileDialog As New OpenFileDialog()

        ' Configure OpenFileDialog to select multiple .shp files
        openFileDialog.Filter = "Shapefiles (*.shp)|*.shp"
        openFileDialog.Multiselect = True
        openFileDialog.Title = "Select Shapefiles"

        ' Show the dialog and check if the user selected files
        If openFileDialog.ShowDialog() = DialogResult.OK Then
            ' Loop through each selected .shp file
            For Each shapefilePath In openFileDialog.FileNames
                ' Add the file name to Column 1
                Dim rowIndex As Integer = DataGridView1.Rows.Add()
                DataGridView1.Rows(rowIndex).Cells(1).Value = System.IO.Path.GetFileName(shapefilePath)


                ' Read features from the shapefile
                For Each feature In Shapefile.ReadAllFeatures(shapefilePath)
                    ' Loop through attributes and add non-empty values to tableNames
                    For Each attrName In feature.Attributes.GetNames()

                        If Not String.IsNullOrEmpty(attrName) Then
                            Dim attrValue As String = feature.Attributes(attrName)?.ToString()
                            If Not String.IsNullOrEmpty(attrValue) Then
                                tableNames.Add(attrValue)
                            End If
                        End If
                    Next

                Next

                ' Populate the combobox for table names in Column 2
                Dim comboColumn1 As DataGridViewComboBoxColumn = DirectCast(DataGridView1.Columns(2), DataGridViewComboBoxColumn)
                comboColumn1.Items.Clear()
                comboColumn1.Items.AddRange(tableNames.ToArray())

            Next
        End If

Thanks
