Merging database code with autogenerated code

I have an app that I started by using the IDE to drop boxes onto a form and then bound them to the underlying database with dataadapters and binding sources. When I step through the records the fields (textboxes) change appropriately, but edits are not written to the database. The following code was generated by the IDE:

        [global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
        [global::System.ComponentModel.Design.HelpKeywordAttribute("vs.data.TableAdapter")]
        public virtual int Update(orsDataSet2.ORS_ENTITIESDataTable dataTable) {
            return this.Adapter.Update(dataTable);
        }
       
        [global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
        [global::System.ComponentModel.Design.HelpKeywordAttribute("vs.data.TableAdapter")]
        public virtual int Update(orsDataSet2 dataSet) {
            return this.Adapter.Update(dataSet, "ORS_ENTITIES");
        }
       
        [global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
        [global::System.ComponentModel.Design.HelpKeywordAttribute("vs.data.TableAdapter")]
        public virtual int Update(global::System.Data.DataRow dataRow) {
            return this.Adapter.Update(new global::System.Data.DataRow[] {
                        dataRow});
        }
       
        [global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
        [global::System.ComponentModel.Design.HelpKeywordAttribute("vs.data.TableAdapter")]
        public virtual int Update(global::System.Data.DataRow[] dataRows) {
            return this.Adapter.Update(dataRows);
        }

What do I need to add and where do I add it to have the data updated?
