Kevin, I know these old articles probably haunt you forever (especially around Holloween), but they sure help. I've been trying to add this "New" button to the Web OrderDetails exercise, but I can't get it to work. For one, it seems your call to NewRow in your example doesn't match any of the MM overrides. So I tried it with a DefaultValues object as the last parameter, in which I set the OrderID. Now, the new row is getting created, but all the values are null. The DefaultValues object is ok (used your example). Here's my code that adds the new row: This doesn't generate an error, but the new row doesn't get the OrderID value I passed.

		private void btnNew_Click(object sender, System.EventArgs e)
		{
			// Retrieve the previous Order Detail DataSet
			DataSet dsOrderDetail = (DataSet)Session["dsOrderDetail"];
			// Add a new row to the DataSet
			this.oOrderDetail.NewRow(dsOrderDetail, this.oOrderDetail.TableName,
				new OrderDetailDefaultValues(this.OrderID));
			// Store the DataSet back into the session
			Session["dsOrderDetail"] = dsOrderDetail;
			// Set the new row for editing
			this.grdOrderDetail.EditItemIndex = dsOrderDetail.Tables[oOrderDetail.TableName].Rows.Count-1;
			// Rebind the DataGrid
			this.BindControl(this.grdOrderDetail);
		}

Thanks for any help. BTW, I could not find the instructions for adding a new row to an in-line editing grid in the latest Dev Guide. It would be great to have that.


>>What is the recommended way to add records from a form or a grid when you are creating a web application. THe jumpstarts don't talk about this at all, and I am having problems with Autoincrementing messing something up with my dataset updates. namely it overwrites data on the first record. Could someone give me a step by step procedure of what is the best way to do this?

>In your web form's Page_Load, if posting back, rather than retrieving the DataGrid data from the business object again, you should retrieve it from the Session variable (which contains the DataSet with the new row in it), and then you should call the business object's SetCurrentDataSet method so all of the binding occurs properly.
