}

これは、リストボックスに入力するために使用したコードです

今、次のような3つの列を持つグリッドビューが必要です:

Name     Age      Rel

したがって、最初の 3 つの値がグリッドビューの最初の行に挿入され、2 番目の 3 が 2 番目の行に挿入されます。

助けは素晴らしいでしょう。

DataTable を使用して行を格納し、すべてのレコードを読み取った後、それを GridView にバインドできます。

protected void Button1_Click(object sender, EventArgs e)

    GridView.DataSource = table;
    GridView.DataBind();
