I have a GridView that I populate manually using OpenFileDialog...

        Dim fname As String = ""

        If (dlgImportClients.ShowDialog() = Windows.Forms.DialogResult.OK) Then
            fname = dlgImportClients.FileName
        End If

        Dim TextLine As String = ""
        Dim SplitLine() As String

        If System.IO.File.Exists(fname) = True Then
            Dim objReader As New System.IO.StreamReader(fname)

            Do While objReader.Peek() <> -1
                TextLine = objReader.ReadLine()

                'need to add false for checkbox column
                TextLine = "False," + TextLine

                SplitLine = Split(TextLine, ",")

                dgvClients.ColumnCount = SplitLine.Count
                dgvClients.MasterGridViewTemplate.AllowAddNewRow = False
                dgvClients.ReadOnly = False
                dgvClients.Columns(0).IsVisible = True

                'if .RowCount = 0 then we are processing the first row
                If dgvClients.RowCount = 0 Then
                    For i = 1 To SplitLine.Count - 1
                        With dgvClients
                            .Columns(i).HeaderText = SplitLine(i).ToString
                        End With
                End If

            'stupid but the only way I could get the datagridview to populate correctly
            If dgvClients.RowCount > 1 Then
            End If
            RadMessageBox.Show("File Does Not Exist")
        End If

I am loading the .CSV file to the GridView so that it can be reviewed, cleaned up, and then imported into Clients table within the customers database.

I'm kinda stumped as to the best way to get the data in the GridView into the database. Could just be a brain fart or I may be going about this totally wrong. Any insight would be greatly appreciated.

Hi Bob,

Thank you for your question. In order to commit data from an unbound RadGridView, you will have to use the SqlCommand.ExecuteScalar method. Please refer to the msdn page on SqlCommand for more information. Do not hesitate to write back if you need assistance with our controls.

All the best,
the Telerik team
