All I get is a Data Row View object that is basically useless to me because I cannot add it to the Binding Source. Add(row View) but get an error that I cannot add an external object. Row; If you are using strongly typed datasets, you can cast the Data Row to that type. Add New() as Data Row View; Supplies Data Row data Row = row View. End Edit(); In the combo Menu List Combo Box, there is a new line that now says "New Item" instead of being blank, so I seam to be editing the actual Binding Source. The problem is that I cannot change the Binding Source. So my form initiates this object, gives it an SQL Select Query (or built in query), and recieves a Data Set with the Data Table inside.What I want is to add a row in which all of the fields start out as Null. Row as Supplies Data Row; You can initialize the values by specifying a default value for the datatable's column: Supplies Data Table. The problem is that when I click on "New Item", all of the other data bound Textboxes, Combo Boxes, Check Boxes do not update. I also have a private Binding Source bs Supplies object.I also kind of just want to know what is going on because if I am doing something majorly wrong I do not want new problems to come up later. If you have set up your database to not allow nulls for certain columns then those corresponding datatable columns should have a default value set.When adding a new row those fields will be automatically prepopulated. You can validate whether those fields are populated at your save event to ensure they are never committed if not populated. You can validate data by handling the xref: System. Data Grid View class provides a convenient way to perform validation before data is committed to the data store. Check the documentation on the Sort property from the Binding Source on MSDN.

Extender providers are an under-used feature of C#, probably because of the strange way you implement them. For example, an extender provider can store information for controls or catch control events and take action when they occur.

The combo Menu List does have a new blank item after I call btn Add New_Click, but when I select it the Binding Source. Thanks for your help though, I hope it is just something simple that I am not doing right so if there are any other steps you can think of I appreciate it. Once I recieve the Data Set (ds), I initiate the bs Supplies object with this code: bs Supplies = new Binding Source(ds, "Supplies"); I then bind all of my form's objects to this Binding Source.

Count = 4 at this point, but I cannot move bs Supplies. I dont seam to have a problem actually creating the new Row.

I've a Binding Source object that contains a list of objects.
