return confirm for detailsview CommandField

[Johann]

Dear All

I am trying to create a button for the insert and the save action, so
that before the user submits the changes, he is prompted with an alert
box to confirm if he wants to submit the changes or not.

I have the following code at the moment:-

<aspetailsView ID="viewAddressBook" runat="server"
AutoGenerateRows="False" DataKeyNames="ID"
DataMember="DefaultView" DataSourceID="dsAddressBook" Height="50px"
Width="400px"
OnItemInserting="viewAddressBook_ItemInserting"
OnItemUpdating="viewAddressBook_ItemUpdating" SkinID="detailsSkin"
OnItemCommand="viewAddressBook_ItemCommand"
OnItemCreated="viewAddressBook_ItemCreated">
<Fields>
<asp:CommandField ShowEditButton="True" ShowInsertButton="True"
ButtonType="Image" CancelImageUrl="~/Images/CancelIcon.gif"
DeleteImageUrl="~/Images/DeleteIcon.gif"
EditImageUrl="~/Images/EditIcon.gif"
InsertImageUrl="~/Images/SaveIcon.gif"
NewImageUrl="~/Images/NewIcon.gif"
UpdateImageUrl="~/Images/UpdateIcon.gif" />


Can you please help me out

Thanks for your time and help

Johann
