I can't find any examples for this, we have Q3 2009 on our environment, I know you guys mentioned that this will be done in 'future' versions, does this version have this feature? I have 2 columns on my combobox using the headertemplate/itemtemplate. Is it possible to sort the items under each column by clicking on the header? Some code examples would be appreciated. Thanks.

Dynamically create controls in dock using Ajax

Hope someone can help

I have a single RadDockZone with two RadDock's called Admin and Content.

On initial page load I dynamically load a user control into the Admin dock area and this control has a number of buttons on it labelled with various functions such as 'Categories', 'Companies' etc.

What I want to happen is if a button is pressed a user control that is related to that button is dynamically created and added to the controls collection of the content dock control. However, I would like it to do this without a full page postback.

Is this possible and if so can anyone tell me how to do it?

One other caveat is that the content user controls have there own RadAjaxPanels etc. on which may spoil things.

Thanks for any help.

Add URL Link in Exported PDF

Hi, I am exporting a RadGrid to PDF. Everything works great.

I now want to add an href URL link into the PDF but outside of the grid. Is this possible?

My preference would be just below the Page Title.

Thanks,

RadToolTip on RadListView, paging problem

Hi all

I have a problem with a paging RadListView with ToolTips on every Item, embedded in a UserControl.
On the first page, everything look well and works like expected (mouse over a thumbnail picture opens a tooltip with a bigger image).
On all other pages, the tooltip does not appear.
i compared the html source code of both pages and both pages are identical.

i tried to do it like in the online example: what's wrong?

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="RadListViewTissue"> 
        
                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="RadListViewTissue" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                            <telerik:AjaxUpdatedControl ControlID="RadToolTipManager1" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                        </UpdatedControls>

Diff engine out of memory exception

We have been using the RadEditor's diff engine for some time now to compare strings, and it has worked quite well for us. Recently, however, we have run into a problem where were are seeing the exception "system.outofmemoryexception was thrown" when comparing two long XML strings.

Here is how we use the diff engine:

    
            Dim strValue1 As String  
        
            Dim strValue2 As String  
        
            Dim strResult As String  
        
            Dim diff As New Diff.DiffEngine  
        
            ' ...code here assigns long XML strings to strvalue1 and strvalue2; srvalue1's length = 93145; strvalue2's length = 113236...  
        
            strResult = diff.GetDiffs(strValue2, strValue1)

Are there length limitations for the strings that can be passed to the diff engine?

Thanks,

Full RadEditor with MOSS and Internet Explorer

Hello,

I am testing the Full RadEditor for MOSS in list items, and it looks like it doesn't work in Internet Explorer 6 and 8 (I haven't tested with 7). More specifically the content of the RadEditor is never persisted.

However, it works fine with FireFox and Chrome.

Is anyone from Telerik aware of this issue?

Thanks in advance for your help,

Raphael.

[Solved] How to set "All day" event to persist across timezone changes?

Example scenario: Headquarters office creates an AllDay event, and that particular user is in Central Standard Time. When the employees from the Eastern or Pacific timezone offices look at the calendar the appointments do not show as "all day" but instead as a huge appointment ranging from 1:00am day of the event, to 1:00am the day after an event (times given are just an example), however all users in the CST offices see the appointment correctly.
---------------------------------------------------

The UTC correction is getting applied to these all day events, and In need to make sure that doesn't happen. I figure I can intercept this in the GetAppointments & GetAppointment events of the provider, but I'm just not sure how to apply this appropriately.

For my holidays (which works correctly) I'm using:

    
            apt.Start = Convert.ToDateTime(holiday.StartDate).Subtract(owner.TimeZoneOffset); 
        
            apt.End = Convert.ToDateTime(holiday.EndDate).Subtract(owner.TimeZoneOffset);

The diffrence between my holiday data and the appointment data the users are creating is the hours. Holidays are set as 12AM (2010-01-01 00:00:00.000) and the users are set to their timezone (e.g. 2010-01-01 06:00:00.000). Since the hour is unpredictable based on the creating users timezone, would it be advisable to just set the what ever is in the hour (06 in the example above) to 00 ?

Does this sound like an accurate chain of events?

Intercept the setting of the current date
determine the time span and find if this is a 24hr event (what happens in n-day events? 72hrs, 48hrs, etc.)
If it is, continue, if it's not set the existing DateTime.
Set the dates hour to zero
subtract the current TimeZoneOffset of the scheduler
set the new value as the DateTime to use

[Solved] LoadingMessage not showing

I've tried adding a 'Loading'-message while the tree expands the childnodes, but the code below doesn't show any message. What am I missing?

Admin.aspx:

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Admin.aspx.cs:

using Telerik.Web.UI;

public partial class TestAdmin : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
   RadTreeNode root = new RadTreeNode("Root", "0");

root.ExpandMode = TreeNodeExpandMode.ServerSide;

   RadTreeView1.Nodes.Add(root);
        }
    }

    protected void RadTreeView1_NodeExpand(object sender, RadTreeNodeEventArgs e)
    {
  RadTreeNode node;

  for (int i = 0; i < 1000; i++)
  {
   node = new RadTreeNode("New node " + i.ToString(), "New value");

node.ExpandMode = TreeNodeExpandMode.ServerSide;

   e.Node.Nodes.Add(node);
  }
    }
}
