How do I access my ImageButton CommandArguments using c#?

I am trying to access my EventArgs from an imagebutton.  How do I do this?

Here is my incomplete code.

<asp:ImageButton ID="edittemplate" OnClick="EditTemplate" runat="server" ImageUrl="images/view.jpg" CommandArgument='<%#DataBinder.Eval(Container.DataItem, "EventID")%>' />

      void EditTemplate(object sender, System.EventArgs e) {

            sSQL = "SELECT * FROM Events WHERE EventID = " + ARGUMENT "id" GOES HERE!!!!!

I solved my own question...Please read the solution below.

1.     Change EditTemplate into an OnCommand call.

<asp:ImageButton ID="edittemplate" OnCommand="EditTemplate" runat="server" ImageUrl="images/view.jpg" CommandArgument='<%#DataBinder.Eval(Container.DataItem, "EventID")%>' />

2.    Change to a CommandEventArgs e

void EditTemplate(object sender, CommandEventArgs e) {

3.    Access using e

sSQL = "SELECT * FROM Events WHERE EventID = " + e.CommandArgument;

add this code and use the query like this
Button sender1 = (Button) sender;

sSQL = "SELECT * FROM Events WHERE EventID = " + sender1.CommandArgument;
