I am having the hardest time trying to get the value of a rad treenode when i'm using the radcontextmenu.  When I right click the item, I'm using the OnClientContextMenuShowing event to be able to capture this information in javascript.  How can I get the value of the treenode that the context menu is associated with.  Also, if I view source on the page with the rad treeview, I can't see the value stored anywhere in the html like I would if I set the value of a ASP.Net treeview control.  Any help would be appreciated as this should be a relatively easy and common scenario.  I don't want to use server side options just to be clear.  Thanks in advance for your help.

Hello,

I have created a custom skin.  It was derived from a classic version skin, changed to match Ajax version taxonomy.  Unfortunately, the default skin (RadPanelBar.css) still overrides many of my settings.  I know my custom skin is working because the results show my images and some of my settings that are not contained within the default Css.  How do I stop the CssClass reference from being added, or how do I add an empty default Css?

Here is my page registration:

 <link href="/_skins/RadPanelBar/SoEasy/PanelBar.SoEasy.css" rel="stylesheet" type="text/css" runat="server" />

(The structure is as indicated within the documentation whereby there is also a PanelBar directory within .../SoEasy that contains my images.)

Here is my control callout:

     <telerik:radpanelbar runat="server" ID="RadPanelbar1" ExpandMode="MultipleExpandedItems" ExpandDelay="3000" CollapseDelay="3000" EnableEmbeddedSkins="false" Skin="SoEasy" DataSourceId="QuickLaunchSiteMap" OnClientLoad="panelLoad" OnClientItemClicking="OnClientItemClickingHandler" OnClientMouseOver="OnClientMouseOverPanHandler" OnPreRender="RadControl_PreRender" PersistStateInCookie="false" ToolTip="">
     
      <ExpandAnimation Type="Linear" Duration="300" />
      <CollapseAnimation Type="Linear" Duration="100" />     
     </telerik:radpanelbar></div>

Here is the resulting output showing the default RadPanelBar having precedence over my custom skin:

<div class="RadPanelBar RadPanelBar_SoEasy nothing" id="ctl00_PlaceHolderLeftNavBar_RadPanelbar1">
  <ul class="rpRootGroup">
   <li class="rpItem rpFirst rpLast"><a class="rpLink rpExpandable rpExpanded" href="/sites/master/site%20pages/go_nowhere.aspx"><span class="rpOut"><span class="rpText">Community Access</span></span></a><div class="rpSlide" style="height: auto; display: block;">
    <ul class="rpGroup rpLevel1" style="overflow: auto; display: block; width: 100%;">
     <li class="rpItem rpFirst rpLast"><a class="rpLink rpExpandable" href="/sites/master/community/default.aspx"><span class="rpOut"><span class="rpText">Enter Private Site</span></span></a><div class="rpSlide">
      <ul class="rpGroup rpLevel2">
       <li class="rpItem rpFirst"><a class="rpLink" href=" class="rpOut"><span class="rpText">Recover Password</span></span></a></li><li class="rpItem rpLast"><a class="rpLink" href=" class="rpOut"><span class="rpText">Create Account</span></span></a></li>
      </ul>
     </div></li>
    </ul>
   </div></li>
  </ul><input type="hidden" name="ctl00_PlaceHolderLeftNavBar_RadPanelbar1_ClientState" id="ctl00_PlaceHolderLeftNavBar_RadPanelbar1_ClientState" autocomplete="off" value='{"expandedItems":["0"],"logEntries":[],"selectedItems":[]}'/>
 </div>

Your help would be appreciated.

Thank you,

I am having a problem with the onkeyup event when using a RadTextBox.  Its seems to fire ok, however the changes to the text field are not reflected before the event fires.  So when it fires, any text entered that causes the event is not being seen in my javascrip fuction.  Has anyone seen this before?  If so, how do i rectify it?

Thanks in advance.

Hello,

I am attempting to evaluate the Telerik suite for purchase.  I am currently going through the RadControl for ASP.net ajax courseware .pdf. (794 Pages).   I am trying to get client side databinding to work for the grid.  I am using the tutorial on page 501 titled client side databinding.

I went through the tutorial and I also simply ran the packaged code of the very same tutorial and I am getting the same error in both my application and the example that was distributed with the tutorial.

I am getting the following error:  'Null" is null or not an object.

This error happens when the following line of code is called from within the javascript function updateGrid(result)

error happens here ---> tableView.set_dataSource(result);

when I break into the c# code, my customer objects are getting populated and when I check what "result" is in the javascript updateGrid() function just before calling the set_dataSource(result) line it shows a populated object.  Not sure why the above line of code keeps bombing. 

Can someone who has worked with these tools please verify to me that the sample project works for this tutorial. Any suggestions?

I am currently evaluating version 2008.3..1125.35 and using VS 3.5 SP 1

Hi:
 In this sample Radcombox with checkboxes

How can I select the first option in the codebehind, so Its text can appear in the textbox and its correspondent checkbox is checked.

Thanks in advance.

I keep getting an error when trying to view the design of a radpanelbar on a form. The control is fine when typing the code and during run time, but cannot be viewed in the Design mode.

The error that is displayed:
"Error Creating Control - telerik:radpanelbar"
Failed to create designer 'Telerik.Web.UI.RadPanelBar, Telerik.Web.UI, Version=2009.2.701.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4'

I am using Visual Studios 2008 Version 3.5 SP1 and RadControl for ASP.NET AJAX Q2 2009.

Any help would be greatly appreciated.
