    Folks, Attached I am sending 2 URL's from MSFT ASP.net Quick Start
    Tutorial Web Site.

    1) Run it URL:
    2) View Source URL:

    I do understand from the Master Page
    (GridViewMasterDetailsInsertPage_vb.aspx) the last field from Gridview1
    (Hyper Link field) is calling (DetailsViewEdit_vb.aspx) with
    DataNavigateUrlFields="au_id". Also the Gridview1's SqlDataSource
    ID="SqlDataSource1" and it's SelectCommand="SELECT [au_id], [au_lname],
    [au_fname], [state] FROM [authors] WHERE ([state] = @state)". I
    understand the logic Perfectly.

    Also in (DetailsViewEdit_vb.aspx) its SqlDataSource
    ID="SqlDataSource3" SelectCommand="SELECT [au_id], [au_lname],
    [au_fname], [phone], [address], [city], [state], [zip], [contract] FROM
    [authors] WHERE ([au_id] = @au_id)".

    It's <SelectParameters>
    <asp:QueryStringParameter Name="au_id" QueryStringField="ID"
    Type="String" />

    That is, the value QueryStringParameter Name is coming from Master Page
    I do understand this logic also.

    However after Update or Cancel from (DetailsViewEdit_vb.aspx), it is
    returning to Master Page by using
    I do understand this logic too.

    My intention is this:
    for Example, in (GridViewMasterDetailsInsertPage_vb.aspx) in
    DropDownList1 user selects State = "NY", Gridview1 filters only shows
    records from "NY", they click 'Edit' button to invoke

    I would like to see that after they select 'Update' or 'Cancel' from
    Detail page, Master Page (GridViewMasterDetailsInsertPage_vb.aspx)
    Gridview1 should show only records from State = "NY". Because this is
    the Orginial selection prior to calling (DetailsViewEdit_vb.aspx). If
    so, what will be the Command or Commands and where they will be
    issued? Master or Detail Page?

    Currently Gridview1 is showing null in Master Page after response
    redirect from Detail Page.

    I admit I am new to .Net but I must need to start somewhere. Any Help
    will be sincerely appreciated...
