Changing hyperlink.

I have the hyperlink below that redirects the client to a page where they can isert a new record. I want this to load within the same page.
<asp:HyperLink ID="HyperLink1" ImageUrl="~/images/add.gif" Text="New" NavigateUrl="DetailsViewInsert.aspx" runat="server" /><small>new</small>

*
First EquipmentType is selected, once a type is selected a search is done in inventory for this equipmenttype. This is displayed in a gridview in which the item can be selected or deleted. If selected it allows the option to edit or add a new record. I would like the functionality of the add to be used instead of having to use the hyperlink to a form as stated above. This seems to be redundant to me when the code already exists to do this. I hope I am not confusing the person reading this but I am not familar with the terminology for what I need to accomplish. Thanks.

Below is the code for the app :

<%@ Page Language="VB" %>
<script runat="server">

    Protected Sub DetailsView1_ItemInserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewInsertedEventArgs)
   
        If (Not e.Exception Is Nothing) Then

            ErrorMessageLabel.Text = "An error occured while entering this record.  Please verify you have entered data in the correct format."
            e.ExceptionHandled = True
        End If
        GridView1.DataBind()
    End Sub

    Protected Sub DetailsView1_ItemUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdatedEventArgs)
   
        GridView1.DataBind()
    End Sub

    Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
   
     
        DetailsView1.ChangeMode(DetailsViewMode.ReadOnly)
       
    End Sub

    Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
   
        DetailsView1.ChangeMode(DetailsViewMode.ReadOnly)
    End Sub

    Protected Sub GridView1_PageIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
   
        DetailsView1.ChangeMode(DetailsViewMode.ReadOnly)
    End Sub

    Protected Sub GridView1_Sorted(ByVal sender As Object, ByVal e As System.EventArgs)
        DetailsView1.ChangeMode(DetailsViewMode.ReadOnly)
    End Sub
   
    Protected Sub GridView1_RowDeleted(ByVal sender As Object, ByVal e As GridViewDeletedEventArgs)
   
        If (Not e.Exception Is Nothing) Then
       
            ErrorMessageLabel.Text = "Failed to DELETE due to foreign key contstraint on the table.  You may only delete rows which have no related records."
            e.ExceptionHandled = True
        End If
    End Sub

    Protected Sub DetailsView1_DataBound(ByVal sender As Object, ByVal e As EventArgs)
   
        If (DetailsView1.CurrentMode = DetailsViewMode.Insert) Then
       
            Dim stateTextBox As TextBox = CType(DetailsView1.Rows(6).Cells(1).Controls(0), TextBox)
            stateTextBox.Text = DropDownList1.SelectedValue
            stateTextBox.Enabled = False
        End If
    End Sub
    Protected Sub Dropdownlist1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList1.DataBound
        DropDownList1.Items.Insert(0, New ListItem("SELECT TYPE", "0"))
    End Sub

You did confuse me but thats not hard to do.
Lets say I am the user surfing the site now. You want me to be able to click on a link to open DetailsViewInsert.aspx and just start adding a new records without having to click on anything else? or am I missing something here?

Yes that sounds right. Currently we can do that but we have to click on a hyperlink that redirects to an insert page.

Place your controls (the dropdownlist, gridview, hyperlink) on a panel. The detailsview not.
When clicking the hyperlink set Panel1.Visible=false and your DetailsView1.Visible=true. (et vice versa)

Is that the thing you want to do?
