Adding and Responding to Buttons to a GridView:
Step 7-Adding the Increase and Decrease Buttons to the GridView
This step of the VIDEO TUTORIAL will show case on how to add the ‘Price+10%’ and ‘Pric-10%’ buttons to the ItemTemplate of the GridView control to display on each and every row of a product belonging to Supplier that is listed in the FormView control. These button controls will invoke the newly created overload of the ‘UpdateProduct’ method from the ProductsBLL layer via the GridView control’s RowCommand event handler, when a user clicks on these button controls. Finally, the functionality of increasing or decreasing a product’s unit price belonging to a supplier listed in the FormView control on the page is demonstrated at run time. For detailed information and source code for this step, please refer to the original article.
