DataGrid Delete Popup Box asp.net (vb)

SEE HOW DO I MAKE THIS WORK.....
When I click on the "Delete" Button, I am wanting a javascript confirm box to appear.  I want to create this script in the code behind and not in the HTML portion.  Any suggestions for the "onclick" attributes to a datagrid button?

'HERE IS MY DELETE BUTTON in HTML Code
<asp:ButtonColumn Text="Delete" ButtonType="PushButton" CommandName="Delete"></asp:ButtonColumn>


'DATAGRID
 Sub dgLinks_Click(ByVal source As System.Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgLinks.ItemCommand
        If e.CommandName = "Edit" Then
            pnlEdit.Visible = True
           
        ElseIf e.CommandName = "Delete" Then

Goes somethig like this

Sub DataGrid_ItemCreated(Sender As Object, e As DataGridItemEventArgs)
        Select Case e.Item.ItemType
          Case ListItemType.Item, ListItemType.AlternatingItem, ListItemType.EditItem
            Dim myDeleteButton As Button
            myDeleteButton = e.Item.FindControl("btnDelete")

Is there a way where I could make it work within my datagrid_click event within this ElseIf statement?

 ElseIf e.CommandName = "Delete" Then

            Dim objDeleteData As New clDeleteData
            Try
                'Delete News Events
                objDeleteData.DeleteApp(CType(dgLinks.DataKeys(e.Item.ItemIndex), Integer))
                'redirect back to the page
                'Response.Redirect("menu.aspx")
            Catch ex As Exception
                Throw New Exception(ex.Message)
            Finally
                objDeleteData = Nothing
            End Try
        End If
    End Sub
