    <p>No problem sh4, glad it helps w/ the mixed type issue.</p> <p>The DateTime column is whole other animal that I recall caused me grief in the past... we have one excel file we process that the OleDbDataAdapter will sometimes convert dates to a double data type (apparently Excel stores dates as doubles, which encode the number of days elapsed since January 0, 1900 ). </p> <p>The workaround was to use:</p> <pre><code>OleDbConnection mobjExcelConn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + txtExcelFile.Text + @";Extended Properties=""Excel 8.0;IMEX=1;HDR=Yes;"""); OleDbDataAdapter mobjExcelDataAdapter = new OleDbDataAdapter("Select * from [" + txtSheet.Text + "$] where [Supplier ID] &lt;&gt; '' ", mobjExcelConn); DateTime dtShipStatus = DateTime.MinValue; shipStatusOrig = excelRow["Est Ship Date"].ToString(); // excelRow is DataRow in the DataSet via the OleDbDataAdapter if (shipStatusOrig != string.Empty) { // Date may be read in via oledb adapter as a double if (IsNumeric(shipStatusOrig)) { double d = Convert.ToDouble(shipStatusOrig); dtShipStatus = DateTime.FromOADate(d); if (DateTime.TryParse(dtShipStatus.ToString(), out dtShipStatus)) { validDate = true; Debug.WriteLine("{0} converted: ", dtShipStatus.ToString("s")); } } else { if (ValidateShipDate(shipStatusOrig)) { dtShipStatus = DateTime.Parse(shipStatusOrig); validDate = true; Debug.WriteLine("{0} converted: ", dtShipStatus.ToString("s")); } else { validDate = false; MessageBox.Show("Invalid date format in the Excel spreadsheet.\nLine # " + progressBar1.Value + ", the 'Ship Status' value '" + shipStatusOrig + "' is invalid.\nDate should be in a valid date time format.\ne.g. M/DD/YY, M.D.Y, YYYY-MM-DD, etc.", "Invaid Ship Status Date"); } } ... } public static Boolean IsNumeric (Object Expression) { if(Expression == null || Expression is DateTime) return false; if(Expression is Int16 || Expression is Int32 || Expression is Int64 || Expression is Decimal || Expression is Single || Expression is Double || Expression is Boolean) return true; try { if(Expression is string) Double.Parse(Expression as string); else Double.Parse(Expression.ToString()); return true; } catch {} // just dismiss errors but return false return false; } public bool ValidateShipDate(string shipStatus) { DateTime startDate; try { startDate = DateTime.Parse(shipStatus); return true; } catch { return false; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
