Multiple Save Using C# and SQL Server

Multiple Save Using C# and SQL Server

Saving data in the database takes you a lot of time but, In this tutorial I will teach you how to save multiple data using C# and SQL server 2005. With the use of this method, it wil lessen your work when saving data in the database.This method has the ability to save multiple data in just a click.

Let’s begin:

Create a database and name it “employeedb”.

After creating the database, open Microsoft Visual Studio and create new Windows Form Application for C#. Then do the following design of a Form as shown below.

mulitiSaveSQLfig.1

Go to the Solution Explorer, double click the “View Code”  to display the code editor.

In the code editor, declare all the classes and variables that are needed.

Note: Put using System.Data.SqlClient; above the namespace to access sql server library.

 //initialize all classes
 SqlConnection conn = new SqlConnection();
 SqlCommand cmd = new SqlCommand();
 SqlDataAdapter da = new SqlDataAdapter();
 DataTable dt = new DataTable();

 //declaring variables
 string query;
 int result;

After declaring the classes and variables, establish a connection betweenSQL server and C#.net in the first load of the Form.

private void Form1_Load(object sender, EventArgs e)
 {
 conn.ConnectionString = "Data Source=.\\SQLEXPRESS;database=employeedb;trusted_connection=true;"; 
 }

After that, double click the “Save” button and do the following code in the method. This code is for saving multiple data in just a click.

private void button1_Click(object sender, EventArgs e)
 {

 try
 {
 //opening connection
 conn.Open();

 int maxrow = dataGridView1.Rows.Count - 2;
 //create a loop for getting the total rows in the datagridview that have filled up.
 for (int i = 0; i <= maxrow ; i++)
 {
 //create an insert query;
 query = "INSERT INTO tblemployee (Name,Address,Contact,Emailadd) VALUES('"
 + dataGridView1.Rows[i].Cells[0].FormattedValue +"','"
 + dataGridView1.Rows[i].Cells[1].FormattedValue +"','"
 + dataGridView1.Rows[i].Cells[2].FormattedValue +"','"
 + dataGridView1.Rows[i].Cells[3].FormattedValue +"')";

 //it holds the data to be executed.
 cmd.Connection = conn;
 cmd.CommandText = query;
 //execute the data.
 result = cmd.ExecuteNonQuery();
 }
 

 //validate the result of the executed query.
 if (result > 0)
 {

 MessageBox.Show("Data has been saved in the SQL database");
 
 }
 else
 {
 MessageBox.Show("SQL QUERY ERROR");
 }
 //closing connection
 conn.Close();

 }
 catch (Exception ex)//catch exeption
 {
 //displaying error message.
 MessageBox.Show(ex.Message);
 }

 }
 }

Frequently Asked Questions

What does this C# code snippet demonstrate?

Focused C# WinForms code pattern: how to add, insert, save, search, display, print, or connect to SQL Server with minimum code. Drop-in pattern you can adapt for your own capstone module.

What .NET and SQL Server versions does this project require?

Most projects in this batch use C# WinForms on .NET Framework 4.5+ (the dominant stack for tutorial sites) with SQL Server 2012 Express or higher. A few newer projects use .NET 6/7/8. To run: install Visual Studio 2019 / 2022 (Community edition is free), install SQL Server Express + SSMS, open the .sln file, build, run.

How do I set up the database for this C# project?

Open SQL Server Management Studio (SSMS) and connect to your SQL Server instance (e.g. localhost\SQLEXPRESS). Right-click Databases > Restore Database OR > New Database then import the included .sql script. Update the connection string in App.config (or in code-behind) with your server name + credentials. Rebuild and run.

Can I use this C# project for a BSIT capstone or thesis?

Yes, but extend it. A bare CRUD form is too narrow for full capstone scope. Add: role-based access (admin/staff/customer login redirect), Crystal Reports or RDLC reports, dashboard with Chart controls, audit log, multi-branch support. Pair with Chapter 1-5 documentation matching your panel’s rubric.

Why am I getting ‘connection error’ or ‘object reference not set’?

Three common C# issues: (1) Connection error: SQL Server isn’t running OR connection string in App.config has wrong server name. Open SQL Server Configuration Manager + verify SQL Server (SQLEXPRESS) service is running. (2) NullReferenceException: a control reference or DB column returned NULL, add a check or use ?? operator. (3) Build error ‘The type or namespace could not be found’: missing assembly reference, add via Project > Add Reference.

Where can I find more C# projects with source code?

Browse the C# Projects hub for the full library. For other .NET stacks see VB.NET Projects (300+ Windows Forms systems). For ASP.NET WebForms see ASP.NET Projects. For BSIT capstone idea lists see 150 Best Capstone Project Ideas.
