Question

Building a customizable grid using asp.net to display data from a SQL database and enabling users to edit

I'm currently working on a new project that involves dynamically writing an SQL table into an asp:gridview for editable purposes. I've come across some solutions, but they all seem to be static, and I need a dynamic solution due to the changing nature of the SQL tables.

It is important for the table to be dynamic because the SQL tables may have columns added, removed, or modified. Thus, a static solution won't work for my project.

My ideal scenario would involve an editing function similar to Excel, where the data can be modified and saved back to the SQL table with a simple save button.

I've been researching for at least 4 hours and haven't found a suitable solution yet. I would greatly appreciate any help or guidance on this issue.

Thank you for your assistance.

Best regards

Here is a simple solution for connecting to a SQL database and updating a table:

using System.Data.SqlClient;

namespace test
{
public partial class Form1 : Form
{
    SqlDataAdapter sda;
    SqlCommandBuilder scb;
    DataTable dt;

    public Form1()
    {
        InitializeComponent();
    }

private void Form1_Load(object sender, EventArgs e)
    {
        SqlConnection con = new SqlConnection (@"Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;");
        sda = new SqlDataAdapter(@"SELECT* FROM dbo.MyTable", con);
        dt = new DataTable();
        sda.Fill(dt);
        dataGridView1.DataSource = dt; 
    }

    private void button1_Click(object sender, EventArgs e)
    {
        scb = new SqlCommandBuilder(sda);
        sda.Update(dt);
        MessageBox.Show("Table updated");
    }
}

}

This code snippet allows you to connect to a SQL database, retrieve a table, and update it with changes made through a button click. Note that adding or removing columns is not supported in this implementation.
