Hi!

I want get result like below in GridView in ASP.Net with static method.

Static method meaning without using database.

protected void Page_Load(object sender, EventArgs e)
{
    if(!Page.IsPostBack)
    {
        insertData();
    }
}      
public void insertData()
{
    DataTable dt = new DataTable();
    dt.Columns.Add("Id", typeof(int));
    dt.Columns.Add("Category", typeof(string));
    dt.Columns.Add("Subcategory", typeof(string));
 
    dt.Rows.Add(1, "Fruits", "Apple");
    dt.Rows.Add(2, "Foods", "Oil");
    dt.Rows.Add(3, "Vegetables", "Tomato");
 
    Grid.DataSource = dt;
    Grid.DataBind();
}

Result I want
