Select a Default Node and show highlightes

[Jennifer]

Hi, I am using the tree control. When the page loads I want it to look like the 1st node is selected. I am using the Outlook skin so I want it to highlighted blue.

Basically, when the page loads, I have a tree view on the left side of the page and the data that gets displayed is on the right side of the page. So when you first come to the page, the first node needs to be selected and the right side will already have the data displayed in that area.

Can anyone help. Thanks in advance

Also, when I deployed the site, I included the Telerik DLL of course but I added this line in the web.config because I was getting a Telerik error ScriptResource.axd not found
 <!--<httpHandlers>
      <remove verb="*" path="*.asmx"/>
      <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/>
      <add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" validate="false" />
    </httpHandlers>
   
This helped but now another programmer is telling me I cant have this in web.config in IIS7

It works on my machine but not the deployment server.

Does anyone know the answer here

Hello Jennifer,

Well you can easily set the first node to be with property Selected="true" in the markup of your TreeView, but if on the "right side" is a page loaded all the time and all the pages have representation in the treeView (node with the url to the page), than you can put in the Page_Load of the pages something like the following that will connect the treeView's nodes selection with the currently loaded page:

string url = Request.Url.PathAndQuery;
var correspondingNode = RadTreeView1.FindNodeByUrl(url);
correspondingNode.ExpandParentNodes();
correspondingNode.Selected = true;

About the problem with the config - your colleague is right, the httpHandlers section is used only by IIS 6 and below. For IIS 7 you also need to register the handlers in the system.webServer section.

<system.webServer>
  <validation validateIntegratedModeConfiguration="false" />
  <modules>
    <remove name="ScriptModule" />
    <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
  </modules>
  <handlers>
    <remove name="WebServiceHandlerFactory-Integrated" />
    <remove name="ScriptHandlerFactory" />
    <remove name="ScriptHandlerFactoryAppServices" />
    <remove name="ScriptResource" />
    <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />
  </handlers>
</system.webServer>

Hope this is helpful for you!
