Nested datagridview in vb net windows application

Selecting rows in the master table causes the detail table to update with the corresponding child data. In this walkthrough, you will build the form using two DataGridView controls and two BindingSource components.

When you are finished, you will have a form that shows all the customers in the database in the master DataGridView and all the orders for the selected customer in the detail DataGridView. The following code provides basic form initialization and includes a Main method.

If you use the Visual Studio designer to create your form, you can use the designer generated code instead of this code, but be sure to use the names shown in the variable declarations here. Implement a method in your form's class definition for handling the detail of connecting to the database. This example uses a GetData method that populates a DataSet object, adds a DataRelation object to the data set, and binds the BindingSource components.

Be sure to set the connectionString variable to a value that is appropriate for your database. Storing sensitive information, such as a password, within the connection string can affect the security of your application. Using Windows Authentication also known as integrated security is a more secure way to control access to a database.

For more information, see Protecting Connection Information. The following example includes code that resizes DataGridView columns to fit the displayed data. You will see two DataGridView controls, one above the other. On top are the customers from the Northwind Customers table, and at the bottom are the Orders corresponding to the selected customer.

This application gives you a basic understanding of the DataGridView control's capabilities. You can customize the appearance and behavior of the DataGridView control in several ways:. Change border and header styles. Enable or restrict user input to the DataGridView control. Validate user input to the DataGridView control.

Handle very large data sets using virtual mode. Customize the appearance of cells. Skip to main content. Contents Exit focus mode. Prerequisites In order to complete this walkthrough, you will need: Access to a server that has the Northwind SQL Server sample database. Data; using System.Beings you are new to programming with windows forms application is even a better reason for going the route of a third party control as per Reed's suggestion.

Suppose someone gave you a custom grid that was capable of expanding as you need and at some point in time it fails to function and there is nobody that can fix it for you?

With a 3rd party grid created by a well-known company will always have solutions and patches to ensure you still functioning. Back to Grids, creating and maintaining such a grid personally speaking is more trouble then it is worth and in that regard would not blink an eye to recommend to the customer we need this grid, if not purchased we would revisit the requirement and adjust as needed rather than roll my own grid for expanding data.

Please remember to mark the replies as answers if they help and unmark them if they provide no help, this will help others who are looking for solutions to the same or similar problem.

I agree with you that the DataGrid for Windows Forms is awful to look at, the only thing is that it comes with Visual Studio including Express and therefore in the Express version is free. I mean that making a program using VB needs more than only code to copy and past.

Few days before one of codeproject member asked a question on how to create a Nested or Master Detail or Hierarchical DataGridView for winforms.

I started working on creating a Nested DataGridView sample program which should be useful to all. My aim is to create a simple and easy program for users. User can download the code and can customize depend on their requirement. In real time projects like Order Management, Production management and etc. The waiter from the restaurant will give a menu card to select the item to place an order. Now in a Table total 4 peoples are sitting.

In a restaurant management usually for all tables there will be a unique Table Id or name. All 4 peoples will select their item need from menu card and place the order to serve their food. 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 Order Detail table. Why we need Master and Detail Table? To avoid the duplicate data we can use the master Detail table relation to store our data. To avoid this duplicate data we will create a Master and Detail relation tables.

See the below table for Master and Details. Here we can see all the item details of order in separate table. But in the detail table we have used the Order NO for a relation to the Master table. Using the relation we can combine both the table and produce the out output. The result can be shown without using the Hierarchal grid output. But we have to display the duplicate result as below.

We can also merge the same data and show the result like this below table. But the output is not much good and not easy to view and understand.

Now this final result looks much better then all. It will be easy to view the master and detail of all records. Same like this in our all real time projects we will use the Master and detail relation to display our data. You can view my DataGridView helper class details from my article. I have created two separate list class to populate the master and detail result. In form load called the method to add the details to each list class. This event will be used for the master grid Image click event.

In cell click event if the image column is clicked. I will change the image to Expand and Collapse depends on the selected image name. In cell click event I will get for the current selected Order No.Home Categories. Need Help? Our Support Team is here to help. Ask Question. Form Controls. Populating DataGridView.
