Question

I have a grid view which pulls through data dictated by a stored procedure.

The stored procedure is called GetEverything.
The statement is made up of information from 2 tables, one with person detail, and one with vessel detail. The stored procedure select statement contains the following Where clause:

WHERE Vessel.ArchiveStatus = 0

By default, every new record that is created using the front end application is given a ‘0’ for ArchiveStatus in the db.

So, the gridview will only show me the records where the ArchiveStatus is 0, which by default is evertything.

The 2 boxes, Check All and Uncheck All are working fully.

What I need now is when a REF or REF(s) are selected and the button ‘Archive Records’ is clicked, for the 0 in the database to be updated to a 1 for that VesselREF.

Can anoyone advise how to do this and give me some example code to put in the Default.aspx.vb file/ Event Handler for the archive records button.

With this is place, the grid view will only display the non-archived records, and I can create a seperate grid view with its own SQL to bring through the archived records.

GridView.aspx

    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
        DataKeyNames="REF,VesselREF" DataSourceID="SqlDataSource1" Height="132px" 
        style="text-align: center; font-family: Calibri; font-size: medium" 
        Width="508px" BackColor="#C4FFC4">
        <AlternatingRowStyle BackColor="White" />
        <Columns>
            <asp:TemplateField HeaderText="REF" InsertVisible="False" SortExpression="REF">

                <ItemTemplate>
                    <a href="Details.aspx?REF=<%# Eval("REF")%>"><%# Eval("REF")%></a>
                    <asp:CheckBox ID="RecordSelector" runat="server" />
                </ItemTemplate>
            </asp:TemplateField>
            <asp:BoundField DataField="Title" HeaderText="Title" SortExpression="Title" />
            <asp:BoundField DataField="FirstName" HeaderText="FirstName" 
                SortExpression="FirstName" />
            <asp:BoundField DataField="Surname" HeaderText="Surname" 
                SortExpression="Surname" />
            <asp:BoundField DataField="VesselName" HeaderText="VesselName" 
                SortExpression="VesselName" />
            <asp:BoundField DataField="VesselREF" HeaderText="VesselREF" 
                InsertVisible="False" ReadOnly="True" SortExpression="VesselREF" />

        </Columns>
    </asp:GridView>

Assuming you’re using TemplateFields and you want to use your stored-procedure to set both archived states:

Protected Sub btnArchive_Clicked(sender As Object, e As EventArgs)Handles btnArchive.Clicked
    For Each row As GridViewRow In GridView1.Rows
        Dim chk As CheckBox = DirectCast(row.FindControl("ChkRef"), CheckBox)
        If (chk.Checked) Then
            Dim refID As Integer = Integer.Parse(row.Cells(5).Text)
            ArchiveRecord(refID, True)
        End If
    Next
End Sub

Public Shared Sub ArchiveRecord(refID As Integer, archive As Boolean)
    Using con = New SqlConnection(My.Settings.MyConnectionString)
        Using cmd = New SqlCommand("StoredProcedureName", con)
            cmd.CommandType = CommandType.StoredProcedure
            cmd.Parameters.AddWithValue("@RefID", refID)
            cmd.Parameters.AddWithValue("@Archive", archive)
            con.Open()
            Dim affectedrecordCount As Integer = cmd.ExecuteNonQuery()
        End Using
    End Using
End Sub
