How to assign NodeClick handler in Code Behind?

Hi There

I have master/content page with two ContentPlaceHolders: Nav and Main. both Nav and Main contain UserControls, where Nav has a navigation UserControl (RadPanel with RadTreeView) and Main has a RadGrid (kind of obvious, right ;-) ).

Obviously the objective is to populate the RadGrid with data dependent on the node that is clicked.

Instead of bubbling up events from the user controls, which I find awkward, I thought I could put the NodeClick Event Handler in the code behind on the content page and assign the event handler in the page load event:

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

ContentPlaceHolder cph = (ContentPlaceHolder)this.Master.FindControl("ContentPlaceHolderNav");

RadPanelBar rpb = (RadPanelBar)cph.FindControl("RadPanelBar1");

RadPanelItem itm = (RadPanelItem)rpb.Items[1];

UserControl uc = (UserControl)itm.FindControl("Nav");

RadTreeView rtv = (RadTreeView)uc.FindControl("RadTreeView2");

rtv.NodeClick += RadTreeView1_NodeClick;

}

The code works - when stepping through I can see that the TreeView is found - but the event doesn't fire when clicking on a node (-> a breakpoint in RadTreeView1_NodeClick in the content page is not reached).

Is what I'm trying to do not possible? Or does this just need to go somewhere else in the page lifecycle (Page_Init?).

Thx in advance for help and/or pointers!

Rgds - Marcus.

Two Questions: Saving/loading settings between sessions and Allowing users to hide columns at run-time

We currently have a series of hierarchical radgrids that we'd like to replace with the treelist control. I've gotten most of the basic work done w/ regard to porting from the grid to the treelist, but I can't locate information on how to save / load user settings (e.g., column size, sort order, etc.). (We use the TelerikGridHelper for our rad grids and it works like a champ.) Is there an equivalent tool for saving the treelist settings?

Also, we provide our users with the ability to group columns, sort columns and show/hide columns in the radgrid using the header context menu. How is this done for a tree list? Again, I've looked for it in the documentation, but I'm either overlooking it or it's not there.

thanks -
matt

RADUpload not displaying in IE11

RADUpload is not displaying in IE11 browsers. I have already tried the patch, 4.5 .net upgrade and the browser file but still nothing.

http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/incorrectly-rendered-webpage-when-using-internet-explorer-11.aspx

We are using Q1 2013 controls.

When in IE11, if I change the user agent to IE10 or below it works fine. Is there script in your control that checks for the user agent?

What am I missing?

Thanks,
jamie

I have a grid and a button on my page. On click of the button i reload my grid. I have both of them specified in my AJAXSettings.
I use custom skin for my grid. However, after the AJAX update the skin is overridden from the webresource.axd.

<telerik:RadAjaxManagerProxy ID="RadAJAXManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="_btnGo">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rgBalances" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>
