Find the corresponding row in the data table. The typed dsCategories 
dataset contains a special FindBy method — in this case, the 
FindByCategoryID method — that locates a row by its primary 
key and returns a reference to it. Create a variable for the typed 
data row and call the method: 
// C#
dsCategories.CategoriesRow r;
r = DsCategories1.Categories.FindByCategoryID(key);
