Gridview keep selected Row while pagination

Jun 25 2021 3:06 AM

Hi! I have a gridview, with a button which when is pressed, the row is coloured. Only one row can be selected.

But when I change page, I lose the reference of the row and it´s uncoloured. Here´s an example of my code:

<asp:GridView ID="gvListaTit" runat="server" AutoGenerateColumns="False" DataKeyNames="ID_TITULO_DETALLE" GridLines="Both"
                                     HorizontalAlign="Center"  EmptyDataText="No se han encontrado resultados." AllowPaging="True" OnPageIndexChanging="gvListaTit_PageIndexChanging"
                                     PageSize="3" CssClass="table table-bordered">
                                            <asp:BoundField DataField="ID_TITULO_DETALLE" HeaderText="ID_TITULO_DETALLE" />
                                            <asp:BoundField DataField="DENOMINACION" HeaderText="Denominación" />
                                            <asp:BoundField DataField="EXPEDIDO_POR" HeaderText="Expedido Por" />
                                            <asp:TemplateField HeaderStyle-Width="65px">
                                                    <asp:ImageButton ID="btnSeleccionar" runat="server" CssClass="btn btn-simple btn-accion" ImageUrl="~/Imagenes/Iconos/check_24.png" OnClick="Edit"/>


        protected void Edit(object sender, EventArgs e)
            foreach (GridViewRow row1 in gvListaTit.Rows)
                row1.BackColor = System.Drawing.Color.White;

            ImageButton btn = sender as ImageButton;
            GridViewRow row = btn.NamingContainer as GridViewRow;
            if (row.BackColor == System.Drawing.ColorTranslator.FromHtml("#83CFC6"))
                row.BackColor = System.Drawing.Color.White;
                hididTitulo.Value = null;
                row.BackColor = System.Drawing.ColorTranslator.FromHtml("#83CFC6");
                hididTitulo.Value = row.Cells[0].Text;



How can I keep the selected row coloured when I change page? Thanks!
