In the same manner as Order Management in restaurant projects we also have Bill Master and Detail, Account Master and Detail, Item Master and Detail and Inventory Master and Detail. It will be easy to view the master and detail of all records. Here is my sample output of the hierarchical DataGridView. Now this final result looks much better than all the previous. Let's see now the hierarchical output of the same result.
But the output is not much better and is not easy to view and understand. We can also merge the same data and show the result as in the following table. But we must display the duplicate results as in the following. The result can be shown without using the Hierarchal grid output. Using the relation we can combine both tables and produce the output. But in the detail table we have used the Order Number for a relation to the Master table. Here we can see all the item details of the order in a separate table. Here we can see that the duplicate data has been stored in a separate table as an Order Master Table. See the following table for Master and Details. To avoid this duplicate data we will create a Master and Detail relation tables.
Here we can see that Order No, Table ID, Waiter Name and Order Date have been repeated. For example for every order there will be one waiter and one Table so if we didn't use the Master Detail table relation then the output will be like this below. To avoid the duplicate data we can use the master Detail table relation to store our data. Let's see an example structure of the order. In restaurant management for each order we will create a unique id in an Order Master table and all the item details related to the order in the Order Detail table. All 4 people will select their item from the menu and place the order to serve their food. In restaurant management, usually all the tables have a unique Table Id or name. Now in a table the total of 4 people are sitting in a restaurant. The waiter from the restaurant will provide a menu card to select the item to place an order. Let's consider four people going to a restaurant to have their lunch. In real projects like Order Management, Production Management and and so on we need to display the data in the hierarchical result.įor example let's use an Order Management project for a restaurant. Why to use a Nested or Hierarchical DataGridView

Users can download the code and can customize it depending on their requirements. My intent is to create a simple and easy program for users. I have extended the DatagGridView Helper class to create a Master/Detail DatagGridView.
