I have an asp page that allows the user to enter data and once they click the submit button, the data is inserted into a database file.  I have a stored procedure that inserts the data.  I want the ability to get the auto incremented value of that inserted record so that i can let the user know what that value is.  
It is a primary key.
How can I get this value and display it on my page?

Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
 
        lblError.Visible = False
        lblError.Text = String.Empty
               ' Insert form data into Communications database; alert user to let them know the status of the insert
        Try
            ds1.Insert()
            lblError.Visible = True
            lblError.Text = "Record Successfully Added"
        Catch ex As Exception
            lblError.Visible = True
            lblError.Text = "Problem Adding Record"
        End Try
 
 
Protected Sub ds1_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles ds1.Inserting
        e.Command.Parameters("@TONumber").Value = txtTaskOrder.Text
        e.Command.Parameters("@VisitDate").Value = CalendarControl1.SelectedDate.ToString
        e.Command.Parameters("@VisitAgendaTopics_Scope").Value = txtScope.Text
        e.Command.Parameters("@VisitAgendaTopics_TORevisions").Value = txtTORev.Text
        e.Command.Parameters("@VisitAgendaTopics_Schedule").Value = txtSchedule.Text
        e.Command.Parameters("@VisitAgendaTopics_Resources").Value = txtResources.Text
        e.Command.Parameters("@VisitAgendaTopics_Personnel").Value = txtPersonnel.Text
        e.Command.Parameters("@VisitAgendaTopics_ActionStatusFollowUp").Value = txtFollowUp.Text
        e.Command.Parameters("@VisitAgendaTopics_Deliverables").Value = txtDeliverables.Text
        e.Command.Parameters("@VisitAgendaTopics_OtherCommentsIssues").Value = txtOther.Text
        e.Command.Parameters("@ESTSVisitor1").Value = drpESTSRep.SelectedValue
        e.Command.Parameters("@ESTSVisitor2").Value = ddlESTSRep2.SelectedValue
        e.Command.Parameters("@ESTSVisitor3").Value = ddlESTSRep3.SelectedValue
        e.Command.Parameters("@Customer1").Value = drpCustName.SelectedValue
        e.Command.Parameters("@Customer2").Value = ddlCustomer2.SelectedValue
        e.Command.Parameters("@Customer3").Value = ddlCustomer3.SelectedValue
        e.Command.Parameters("@BranchCodes").Value = ddlBranchCode.SelectedValue
 
    End Sub
 
Here's the ASP Code:
 
<asp:SqlDataSource ID="ds1" runat="server" ConnectionString="<%$ ConnectionStrings:Communications_dbConnectionString %>"
            InsertCommand="insertVisitData" InsertCommandType="StoredProcedure" SelectCommand="Select * from Communications">
            <InsertParameters>
                <asp:Parameter Name="TONumber" Type="String" />
                <asp:Parameter Name="VisitDate" Type="DateTime" />
                <asp:Parameter Name="VisitAgendaTopics_Scope" Type="String" />
                <asp:Parameter Name="VisitAgendaTopics_TORevisions" Type="String" />
                <asp:Parameter Name="VisitAgendaTopics_Schedule" Type="String" />
                <asp:Parameter Name="VisitAgendaTopics_Resources" Type="String" />
                <asp:Parameter Name="VisitAgendaTopics_Personnel" Type="String" />
                <asp:Parameter Name="VisitAgendaTopics_ActionStatusFollowUp" Type="String" />
                <asp:Parameter Name="VisitAgendaTopics_Deliverables" Type="String" />
                <asp:Parameter Name="VisitAgendaTopics_OtherCommentsIssues" Type="String" />
                <asp:Parameter Name="ESTSVisitor1" Type="String" />
                <asp:Parameter Name="ESTSVisitor2" Type="String" />
                <asp:Parameter Name="ESTSVisitor3" Type="String" />
                <asp:Parameter Name="Customer1" Type="String" />
                <asp:Parameter Name="Customer2" Type="String" />
                <asp:Parameter Name="Customer3" Type="String" />
                <asp:Parameter Name="BranchCodes" Type="String" />
            </InsertParameters>
        </asp:SqlDataSource>

In your Stored procedure after inserting record into that table issue the statement

set @val = SCOPE_IDENTITY;

declare @val as an Output parameter of datatype int in your procedure.

Your stored procedure will then return the last inserted key.

Hope this helps

Do I have to put something in my code or better yet, where would I let it be known that the stored procedure is returning a value???

If you change your procedure to accommodate the output column to return a value along with above mentioned modifications, then it would suffice.

I am not familiar in ASP.Net and hence I can't guide you on your Front end code on how to retrieve output values from Stored Procedure.
