Unwanted behavior when editing a row in a grid

I have a asp:GridView paged with datatables . The point is that when I give it to edit, although I keep the page in which I am correctly, the row that I edit becomes the last one of the table in the last of the pages. It's obvious that I need to keep that row where it is.

To edit the row, the only thing I do is to mark the editindex and then I call back the function that binders me the grid.

Edit row

Protected Sub gvConfApp_RowEditing(sender As Object, e As GridViewEditEventArgs)
    gvConfApp.EditIndex = e.NewEditIndex
    Me.pmCargarGrid()
    gvConfApp.FooterRow.Visible = False
End Sub

Grid
