[RESOLVED] Open File Dialogue -- Datagridview

Hi all

The following code uses a OFD to import an Excel spreadsheet to a a DGV.

Code:

---

  Private Sub btnImport_Click(sender As Object, e As EventArgs) Handles btnImport.Click

        Dim strConnectionString$ = "Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0}; Extended Properties=""Excel 12.0; HDR=No;IMEX=1"""



        'DataGridView1.DataSource.rows.clear()
        If ofdSelectFile.ShowDialog = Windows.Forms.DialogResult.OK Then
            strFileName = ofdSelectFile.FileName
            Dim strExcelFileName$ = String.Format(strConnectionString, strFileName)

            con = New OleDbConnection(strExcelFileName)
            DA = New OleDbDataAdapter("select * from [Sheet1$]", con)
            DT.Reset()
            DA.Fill(DT)

            DataGridView1.DataSource = DT

            con.Close()
        Else
        End If

    End Sub

The code works fine... except if i load the OFD and select a new file. If i do this, the DGV doesnt load anything... i mean, its litrally empty, even if i try loading the orignal file.

I've tried adding code to refresh the DGV, i've tried nulling the datasource before loading the new datatable. I'm clean out of ideas. Any help appreciated.

Don't reset the DT... clear it. Or create a new one.
