You can pass the original parameter value to your new parameter in your -ING event (here is DELETING) of your SqlDataSource.
You can use the same logic to do update.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" OnDeleting="SqlDataSource1_Deleting" ….
Code:
protected void SqlDataSource1_Deleting(object sender, SqlDataSourceCommandEventArgs e)
{
{
e.Command.Parameters["@pPartNumberID"].Value = e.Command.Parameters["@PartNumberID"].Value;
//Remove Parameter @PartNumberID
e.Command.Parameters.Remove(e.Command.Parameters["@PartNumberID"]);
e.Command.Parameters.Remove(e.Command.Parameters["@PartNumberID"]);
}
