How To Modify Data?

How do I modify data in a sqlDataSource object (like inserting records, editing, deleting) similiary to how I modify data in a GradView using a DataList or repeater? I want to be able to have my own EditTemplate and be able to edit say four fields while I'm only viewing like two of them in the datalist/repeater.

<asp:DataList ID="DataList1" runat="server" DataKeyField="GameId"

DataSourceID="SqlDataSource1" RepeatColumns="1">

<ItemTemplate>

<%# Eval("field1") %><%# Eval("field2") %>....

</ItemTemplate>

<EditTemplate>......</EditTemplate>



</asp:DataList>

 

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"

ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>"

SelectCommand="SELECT ...."></asp:Sql....>

 

When I'm trying to add a edit-button (<asp:Button runat="Server" ID="EditButton" Text="Edit" CommandName="Edit" />) and click it nothing happens....What is missing?
