This VIDEO TUTORIAL (included in Step 3) will demonstrate on how to assign the CategoryID and SuppliersID parameters to the newly added subset of the Products data table using the adding interface of the previous step. In the previous step we added only Product Name and UnitPrice fields through its interface. This makes the other attributes of the newly created product in the underlying Products database table as null values. However, if we had to assign CategoryID and SuppliersID values of ‘1’ for this newly created product, then we need to assign these values through the ObjectDataSourc1_Inserting event handler and is demonstrated in this step of the video. For detailed information and source code for this step, please refer to the original article.
