No overload for 'save_Click' matches delegate 'System.EventHandler'
<p>I have an asp:button <code>&lt;asp:Button runat="server" ID="save_players" Text="Save Changes" OnClick="save_Click" /&gt;</code> which wants to run the following code, but gets an error "No overload for 'save_Click' matches delegate 'System.EventHandler'".</p>

<p>I recon this is because the method signature does not match EventHandler delegate - but I dont know how to fix it. Any help here please?
Here is my C# method:</p>

<pre><code>protected void save_Click(object sender, ListViewCommandEventArgs e)
{
    foreach (ListViewItem item in ListViewAddPlayers.Items)
    {
        if (item.ItemType == ListViewItemType.DataItem)
        {
            string tournyName = (string)(Session["TournyName"]);
            Label gameNumber = (Label)e.Item.FindControl("lblGame");
            TextBox txtPlayer1 = (TextBox)e.Item.FindControl("txtPlayer1");
            TextBox txtPlayer2 = (TextBox)e.Item.FindControl("txtPlayer2");

            string updateCommand = "//QUERY HERE//";
            SqlDataSource2.UpdateCommand = updateCommand;
        }
    }

    Server.Transfer("tourney-standings.aspx?name=" + (string)(Session["TournyName"]));
}
</code></pre>
