Tooltip lost after SortItems (with workaround)

This is an fyi post for anyone one who might be have a simular problem. I plan on submitting a problem ticket as well.

I have a project which requires two listboxes (transfer back and forth).  The "select from listbox" contains a list of Clients (with each client having a corresponding time zone. One of the requirements is have a dropdown containing time zones just below the "select from listbox". When you select a timezone from the dropdown, the Listbox should select all Clients with matching timezones (so you can easily transfer all clients for that time zone).

No real problem so far, I simply added the RadListBoxItems to the Listbox one at a time looping through the datatable setting the time zone of the client to the tooltip of the RadListBoxItem. With some javascript I snagged from the forums here I was able to loop through the listbox and compare the tooltip with the dropdown selected value, selecting the item if it matches.

Instead of turning on AutoPostBackOnTransfer, I added a button "Sort Lists" that can be clicked if the user feels the need to sort the lists.

Here's where the problem occurs, it seems as though any RadListBoxItem that is moved during the SortItems process looses it's tooltip (if an item isn't moved the tooltip will reamin).

I was able to work around this problem by adding an attribute to the RadListBoxItem (it seems attributes do persist after a sort) and then looping through the ListBox after SortItems and reassigning the Tooltip.

markup :

<table><tr>

<td valign="top">

<asp:Label ID="lblPracticeSelect" runat="server" Text="Practice Select:"></asp:Label><br />

          <telerik:RadListBox ID="rlbPracticeSelect" runat="server" Height="257px" Width="225px"

What is this error and how do I get rid of it?

I've added a chart to my project and am now getting this error. This is an old project I inherited from another programmer. I'm using Q!2010 now, there weren't any Telerik controls previously, or maybe there were and when they weren't used it wasn't cleaned up properly. Anyway I have no idea how to remove anything from the GAC so if someone could help me out here...

CS0433: The type 'Telerik.Charting.Styles.FillStyleSeries' exists in both 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\4d20d014\b4535af6\assembly\dl3\0a6c2faf\0053f0c5_92f6ca01\Telerik.Web.UI.DLL' and 'c:\WINDOWS\assembly\GAC_MSIL\Telerik.Charting\2.0.1.0__d14f3dcc8e3e8763\Telerik.Charting.dll'

Thanks,
Celeste

branding PanelBar

Greetings,

I have been working with a site where administrators can change the color of the site. I have been trying to style my PanelBar to inherit the values from parent. I have tried some of the style examples provided with demo and few different ways. So far I had no luck. I was wondering if there is simple setting I can set to make background color to parent color?

Thanks in advance

2 Treeviews - binding on checkednodes

Hi all,
what i am trying to do is have two treeviews on a page. one is bound to a datasource with checkboxes.

What i want to happen is that as a user checks the checkboxes in one treeview, just the checked items appear in the second treeview.

I tried to bind the second treeview to the RadTreeView1.Checknodes list, but that list does not maintain the different levels of the item. eg. a list like

A
- B
- C
- D
E
- F

So if i select A (that is set to select all the children as well) binding to the checkednodes just gives a flat treeview

A
B
C
D

I want to to come out indented as the original.

Note: if B is selected, A is selected as a partial selection (tristate checkbox) so the full branch should always be selected.

Ideas?

RadEditor, EditModes and Google Crome

Hi,

In Google Chrome (tested in ver. 8 dev and 9 dev.) RadEditor throws an exception "INVALID_ACCESS_ERR: DOM Exception 15" only if EditModes is set to "Preview". Exactly the same RadEditor, but with EditModes="Design" works fine. I'm using RadControls version 2010.3.1109. Problem was in the previous versions too.
In the Firefox 3.6.12 same RadEditor works fine in both modes.

RadRotator is automatically reseting scroll position

Hi,
We've have a radrotator on a page (see http://www.playitback.org/player.aspx?f=257&c=387 as example) in which users can scroll through sets of slides. When the user clicks on a slide, the OnItemClick="ShowImage" is triggered and the image is updated with a new source. The problem I am having is that when a user clicks on image which is located after the initial set (e.g. slide 11), then the position of the RadRotator rewinds and positions back at the start.

Is there anyway of implementing it so that it doesn't reset the scroll position?

Thanks
R

Issue: Radrotator Slideshow and showNext()

Hi..

I'm having trouble with Radrotator Slideshow.

I've had the Radrotator Slideshow with animation type "Fade" for quite a while now. It has been working flawlessly for quite a while as a "banner" module for my project.

I recently updated telerik (for some other reason), so It's the newest version.. Now I also want to add buttons to my slideshow, to allow going back or forward in my banner module. I still want it to work like slideshow though, automatically rotating, like it always have.

So what I did was:
- Add javascript:
    function showNextItem(dir, id) {
        var oRotator = $find(id);
        if (dir == 0) {
            oRotator.showNext(Telerik.Web.UI.RotatorScrollDirection.Right);
        }
        else {
            oRotator.showNext(Telerik.Web.UI.RotatorScrollDirection.Left);
        }
    }

- And add two images OUTSIDE the radrotator with onclick functions like showNextItem(1,'<% =rotator.ClientID %>');

.. At first sight it worked perfectly, but after testing a little, I soon realised that in IE, after clicking abit and letting it scroll a bit (and perhaps change window and back again), the buttons stop working. :-( I can't reproduce the same error in firefox.

Edit: I CAN reproduce the same error in firefox, and in Firefox the slideshow also seems to stop when the problem occurs.

Any Ideas what might be wrong?

Thanks,
Jørgen.
