RadRotator issues with controlbuttons, ajaxpanel,etc

Hi,

I've used radrotator to display some products. Below is the code sample, there are current two problems I'm facing (as listed below)

I'm showing the product description when either user selects the radrotatoritem or when user clicks on the ControlButtons.

1)If I toggle between either of this option I get an error (error screenshot attached)
2)If I toggle between either of this option the product description is shown incorrectly for a product which i've not selected at all. This happens when i toggle between the ControlButtons and clicking on the products themselves.
3) Sometimes I get this error like the below one

A]System.Collections.Generic.List`1[SelectProducts+fileInfo] cannot be cast to [B]System.Collections.Generic.List`1[SelectProducts+fileInfo]. Type A originates from 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' in the context 'LoadNeither' at location 'C:\Windows\assembly\GAC_32\mscorlib\2.0.0.0__b77a5c561934e089\mscorlib.dll'. Type B originates from 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' in the context 'LoadNeither' at location 'C:\Windows\assembly\GAC_32\mscorlib\2.0.0.0__b77a5c561934e089\mscorlib.dll'.

Could you please help me resolve these issues? Thanks

Chrome & Redirect causes Controls in FormDecorator to stay hidden

When a page containing a FormDecorator control is loaded in Chrome via a Redirect, most (but not all) times the controls all stay hidden. I read another post about the delay between the hiding of the controls, decorating them, and showing them, but in this case the controls stay hidden. The issue actually happens on several different pages that are loaded sometimes via a redirect. The pages work normally in Chrome if not redirected to them and work normally in IE and Firefox.

I'm guessing its related to caching redirects in Chrome, but i'm unable to find a workaround (other than disabling the FormDecorator). Any ideas that i might try?

Here's a snippet of my code. The div "displayContainer" contains the controls. Another thing i noticed is that the "skipped" controls stay hidden too.

<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" Skin="Office2007"
        DecorationZoneID="displayContainer" DecoratedControls="All"  ControlsToSkip="Select"  />
 
<div id="displayContainer"> ... </div>

Thanks,
Scott

RadGrid DetailsTable Width

Hi All

I have a RadGrid with a single DetailsTable. How do I force Wrap and set a fixed width on the column of my detail table to match the full width of the master-table. I have tried alot but epxanding the Details it does not wrap and expands the masterview larger than when not expanded. The wrap is mainly for my "Narrative" col in details view.

Any ideas greatly appreciated

Thanks
Stuart

Dynamic Tooltip Problem

Hi all!

I have a problem implementing the RadToolTipManager in my solution. Because the panel that contains it should update itself and my tooltip ascx be generated dynamically. He jumps.

I show an example of my scenario:

Image handler images not displayed when using https in IE9

Hi,

our website works via https.

images generated by image handler are not displayed in IE9 in RadEditor, although they are ok in ImageEditor preview panel :(
https://localhost/[Our site]/Pages/ImagePHandler.ashx?RID=4

If I manually correct the link to make it look like this:
http://localhost/[Our site]/Pages/ImagePHandler.ashx?RID=4

- everything is ok, but this is weird.

p.s. Firefox is ok in all cases.

What can I do?

Dock position changes when clicked on handle

I am having multiple docks of different size ininside a dockzone in a matrix form. The format of the matrices can be small-small-small, medium-small and large in one row.
When a small dock (next or previous to medium dock) is clicked on its handle/grip (intention is to just select the dock NOT to drag), it automatically gets repositioned to the last place in dockzone. If I click on dockbody, it works properly.
I believe this is happening due to client drag/drop events. Can we identify/trap a single click on dock handle?
attachment is the snapshot of dockzone containing docks.

Regards,
Deepak

Odd Behaviour : RadGrid

Found an issue on the following scenario:
1. Radgrid is filled from NeedDataSource event, with GridEditColumn
2. A dropdownlist that will serve as a selective filter for the contents for the radgrid, placed either in the commandtemplate or somewhere else; on dropdownlist selectedindexchange, bind the radgrid according to the selection method
3. Here's the problem
Radgrid is filled with selected record but when "Edit" is clicked on the current record (item), it will rebind the radgrid from the first load (no filter, ALL record) and the item in Edit is now the "first" item in the record.

Any solution? Thanks.

TFS 2010 Build

I've seen various postings that somewhat discuss the issue of using TFS 2010 to do builds on projects that have Telerik references but nothing that describes specifically what needs to be done so I am seeking clarification.

I have a VS2010 solution, within it there is a class library project, unit test project, web project and web deployment project. The web project has a reference to the Telerik Web UI library and while the copy local flag is "true" and the file exists in the local bin directory the physical reference path is a path in my windows profile (Application Data) where hotfix builds are downloaded (via the Telerik VS Extensions). It should be noted that my bin directory in the web project is not checked into source control. Local builds obvisouly work fine but TFS builds fail because the Telerik.Web.UI dll cannot be found since it is not there on the build server. What I am looking for is clarification on exactly what I need to do get the TFS builds to work - I do not have a seperate license for the build server so I don't think installing my license would work without violating licensing agreement. Also, given that I can dynamically update to the a new hotfix version manually copying over the "updated" dll everytime I get a new version would be a time consuming and manual process. Can someone please tell me exactly, in step by step detail what is the best approach to getting the TFS builds to work (and with potentical dynamic updates to the referenced Telerik.Web.UI dll version).
