Question

I have made a basic program to add values to a dataSet and display it to a dataGridView:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        DataTable table1 = new DataTable("People");
        table1.Columns.Add("id");
        table1.Columns.Add("Name");
        table1.Columns.Add("Age");
        table1.Rows.Add(1, "Jack", 18);
        table1.Rows.Add(2, "Tim", 18);

        DataSet set = new DataSet("SetPeople");
        set.Tables.Add(table1);

        dataGridView1.DataSource = set;
        dataGridView1.Update();
    }
}

When I try it out nothing seems to happen. The dataGridView remains blank. Any idea where I am going wrong?

Answer 1

try this

   dataGridView1.DataSource = table1;

you don’t need a Ds for just showing a data table in a Gridview
