Handling vast volumes of data is becoming a normal practice in today’s digital era, and storing them in a database is a crucial part. However, getting and showing this data in an understandable manner might be difficult. In this post, we’ll look at how to use C# to Load data into ListView from DataBase in C#.

Understanding Listview

Before we go into the specifics of loading data into Listview from a SQL Server database, it’s important to understand what Listview is. The Listview control in C# displays data in a tabular style. It enables users to effortlessly sort, filter, and pick data. Listview is a great control for displaying big amounts of data because it has a lot of customization possibilities and is very user-friendly.

Creating a Connection to the SQL Server Database

Following the installation of the SQL Server database, the following step is to connect to it using C#. The SqlConnection class is one of the most often used techniques in C# for establishing a connection to the SQL Server database.

SqlConnection cnn = new SqlConnection("Data Source=MachineName;Initial Catalog=DatabaseName;Integrated Security=True");

Data Loading into a Listview

Following the establishment of the connection, the data from the database is loaded into a listview. The instructions below demonstrate how to load data into a listview using C#:

Create Query to Retrieve Data from SQL Server Database

String sql = "Select Employeeid, FirstName, LastName from Employees";

Create a SqlCommand Object

SqlCommand cmd=new SqlCommand(sql,cnn);

Create a SqlDataReader Object

 SqlDataReader Reader = cmd.ExecuteReader();

Load Data into Listview

while(Reader.Read())
            {
 
 ListViewItemlv = new ListViewItem(Reader.GetInt32(0).ToString());
                lv.SubItems.Add(Reader.GetString(1));
                lv.SubItems.Add(Reader.GetString(2));
                listView1.Items.Add(lv);
 
 
            }

The preceding code generates a query to obtain data from the SQL Server database, a SqlCommand object, and a SqlDataReader object to retrieve the data, and finally loads data into the listview control.

            cnn.Close();
