DataGridView not updating in c#

Question

Anyone got an explanation of what's going on? Changing code 1 to code 2 fixes the problem -although theoretically there should be no difference. (Theory hits practice like a pumpkin hitting a brick wall).

---

Code 1:

 OutputDataGridView.DataSource = myList;

---

Code 2:

 OutputDataGridView.DataSource = null;
 OutputDataGridView.DataSource = myList;

Answer 1

Hai Larry Try this

protected void btnWhateverClick(object sender, EventArgs e)
{
myGridView.DataSourceID = String.Empty;
myGridView.DataSource = new int[0];
myGridView.DataBind();
}

and you're done.
For Ref DataSource in gridview

Hope this helps

Answer 2
