Update right pane from content of Left pane

[Cristian]

Hi I have a radsplitter declared as follows.

<telerik:RadSplitter ID="RdSplt" runat="server" Height="100%" Width="100%" Skin="Windows7">
                        <telerik:RadPane runat="server" ID="rdPnlIzq" Width="30%" ContentUrl="iuMenuProyectos.aspx">

                        </telerik:RadPane>

                        <telerik:RadPane runat="server" ID="rdPnlDer" Width="70%"
                           >
                            Right Pane
                        </telerik:RadPane >
                    </telerik:RadSplitter>

As you can see the rdPnIZq content is loaded from a different page which contains a radTreeView binded on page load as follows.

protected void Page_Load(object sender, EventArgs e)
       {
           cCatalogo oCatalogo=new cCatalogo();
           var ejes = oCatalogo.obtCatEjes();


           if (!IsPostBack)
           {
               var treeNodeReforma = new RadTreeNode("REFORMAS");
               RadTreeView1.Nodes.Add(treeNodeReforma);
               var reformas = oCatalogo.obtCTReforma();
               foreach (var ctReforma in reformas)
               {

                   treeNodeReforma.Nodes.Add(new RadTreeNode(ctReforma.fcDescRef));
                   foreach (RadTreeNode reforma in treeNodeReforma.Nodes)
                   {
                       var radtreenodeEje = new RadTreeNode("EJES");

                       reforma.Nodes.Add(radtreenodeEje);
                       foreach (var eje in ejes)
                       {
                           var ej = new RadTreeNode(eje.fcEje);
                           radtreenodeEje.Nodes.Add(ej);
                           ej.Nodes.Add(new RadTreeNode("PROYECTOS ESTRATÉGICOS"));

                           foreach (RadTreeNode ctproyEst in ej.Nodes)
                           {

                               var s = oCatalogo.obtCatPE(ctReforma.fiIdReforma, eje.fiIdEje);
                                foreach (var proyEstrategico in s)
                                {
                                    var treeNodePE = new RadTreeNode(proyEstrategico.fcDescPE);
                                    ctproyEst.Nodes.Add(treeNodePE);
                                }

                           }



                           //foreach (RadTreeNode rdtnEje in ej.Nodes)
                           //{
                           //    var radtreenodePE = new RadTreeNode("PROYECTOS ESTRATÉGICOS");

                           //    rdtnEje.Nodes.Add(radtreenodePE);

                           //    var s = oCatalogo.obtCatPE(ctReforma.fiIdReforma, eje.fiIdEje);
                           //    foreach (var proyEstrategico in s)
                           //    {
                           //        var treeNodePE = new RadTreeNode(proyEstrategico.fcDescPE);
                           //        radtreenodePE.Nodes.Add(treeNodePE);
                           //    }

                           //}


                       }

                   }
               }
           }
       }

This page is loaded on the leftpane without problems.
But what I want to do is depending on the tree node I hit, load on the right panel a web page with information related to that node.

I tried the example attached to this KB
http://www.telerik.com/support/kb/aspnet-ajax/splitter/use-ajax-request-to-update-part-of-an-external-page-loaded-in-a-radpane.aspx

But in this example the button on the leftpane is placed within the pane itself no from another page like my treeview.

How can I achieve this with the leftpane content loaded from another page?

Hope your help.

Hello,

Please take a look at the following KB article, I believe it will help you solve this case:
Referencing content page in a splitter pane from the parent page and vice versa

Hi Dobromir just one question. Is it posible to do this in code behind

[Dobromir]

Hi Cristian,

In short, no it is not possible to access the content of an <iframe> from the parent page's code behind or vise versa.

Kind regards,
