I have a combo box on a page with some code in the sekectedindexchanged event (this populates a second combo based on the contents of the first)

Whenever I select an item in the first combo box, it initiates a full page postback despite it being setup in an ajax proxy manager, am I doing something wrong ?

Hi, I have a user control that is wrapped by a RadAjaxPanel.  Inside the user control, I have a RadCombo using a template with a TreeView.  This works fine without the AjaxPanel, but I found that the FindNode javascript is failing to find the TreeView on a partial post-back.  It works fine with full post backs.   I should note, I'm using the sample code here for a treeview inside a RadCombo and I'm also using the sample FindNode and other JavaScript (see below for both), and this is a problem with and without the java script inside a RadCodeBlock.

There must be an issue with OnClientLoad and the controls collection at time of partial post back because this works with a full post back.

Note: I'm loading the combo datasource on init view time - i.e. is not postback.  I think that is correct.

thanks
Marty

Hi,

I have a MasterPage with 2 ContentPlaceHolder's on it. The one is for my menu (created with RadPanel) and the other is the actual contents. Is it possible to update the contents_contentplaceholder from the Radpanel without reloading the complete page and without a splitter control on the page?

Thanx

I have one radgrid for that I have set one property AutoGenerateColumns="true".
But I want one column align to right.
Because by default all the column has align left.

Below is the code snipt.
<radG:RadGrid ID="rdgAccEntriesReconcileReport" AllowFilteringByColumn="false" runat="server" AutoGenerateColumns="true"
  AllowPaging="true" PageSize="40" AllowSorting="true" GridLines="None" Skin="Telerik"
   MasterTableView-Visible="true" Width="100%" OnItemCommand="rdgAccEntriesReconcileReport_ItemCommand" OnItemDataBound="rdgAccEntriesReconcileReport_ItemBound"
   SortingSettings-SortedAscToolTip="Click to sort in ascending or alphabetic order"
    SortingSettings-SortedDescToolTip="Click to sort in descending or reverse alphabetic order" OnSortCommand="sortlist">
      <MasterTableView Width="100%">
  </MasterTableView>
      <ClientSettings>
         <Scrolling AllowScroll="true" UseStaticHeaders="true" />
           <Selecting AllowRowSelect="true" />
              </ClientSettings>
               </radG:RadGrid>

Please help if any additional coding or property need to be set.

Hello!

I am in the initial stages of development of an application that will use Telerik's RADControls for ASP.NET AJAX. The web pages will interact with a WCF web service, which will be accessing a relational database management system.

Considering that this will be my first experience with Telerik components, I would appreciate whether someone could provide some assistance in regard to the most adequate component to use.

I have run some of the RADControls for ASP.NET AJAX Q3 2010 Live Examples and noticed that the Scheduler component might offer the features I am looking for. Could you please confirm this component can interact with a WCF web service?

In the "Scheduler / Resource Availability" example, rooms "Meeting room 201" and "Meeting room 202" are displayed side by side. I was wondering how the Scheduler component would handle a scenario where 10 or 15 rooms would have to be managed. Would it be possible for someone from Telerik to add a few rows to the Room table so that I could check the lay out of the page in the Live Example?

Please, let me know if there is another component that could also be used to track availability of resources.
Thank you in advance.
