RadDockLayout, RadZones, RadDock, User-Control, AJAX in Code-Behind

Hi Telerik Team,

My goal is to create a RadDockLayout, RadZones and several RadDocks dynamically. Additionally my RadDocks' content are user-controls that I am dynamically loading at run-time. And all the controls mentioned are wrapped into Update Panels.

What I want to achieve is to have no RadControls defined in the Code In-Front and rather have everything in the code-behind (C#).

My problem is that my controls are disappearing on subsequent post-back (which are initiated by my user-controls). I am aware that I need to re-create the controls on the Page_Load(), but no luck.

Telerik.Web.UI.dll or one of its dependencies requires a later version of the .NET Framework

I have web application with target framework 3.5. When I try to add reference to Telerik.Web.UI.dll (version 2011.2.915.40) I get the following error:
"Telerik.Web.UI.dll or one of its dependencies requires a later version of the .NET Framework than the one specified in project"

If I will add the dll despite the warning I get another error during compilaton:
"SMDiagnostics.dll or one of its dependencies is built by a runtime newer than the currently loaded runtime and cannot be loaded"

Which version of Telerik.Web.UI.dll will work with Framework 3.5?

Error after upgrade

Hi,

I have recently upgraded to .net 4.5.1 and Telerik 2014.1.403.45 and am getting an error in one of my pages. It is a pretty complex page and has grids, radpanes, menu, tabstrip, splitter, toolbar, tooltipmanager and other telerik controls.

The error happens when a user clicks a button that opens a radwindow. The radwindow has a content template and before opening the window we post back to update the content template.

The error is "Uncaught TypeError: Cannot read property 'id' of null"

The line that errors is "if(e[c].id==this._getUpdatePanelID()". e[c] is null. e is an array of 30 DIVs and item 26 is null (all the others are non-null)

The page is pretty complex so it's not easy to give you a test page to show you the error. I could probably put the app on an external web server although I would have to give you a username and password to use on a confidential basis.

Cheers,
Iain

Image Editor not alreays work

Hi Telerik Team,

Our company are using RadEditor and we enabled Image Editor function in Image Manager.

1. We use single web server in our environment, so we use default ImageCacheStorageLocation.
2. we override the Editor's Content Provider, all the files store in db
3. in the same folder, some of images can be displayed in Image Editor popup window but some of them are not
4. If we open an image which can be displayed in Image Editor popup window, we can see there will be 6 requests, the last two requests are images
5. if we open an image which cannot be displayed, we can only see 4 requests.

Do you have any idea why cause this issue and how can we fix it?

You can check the attachment for more details.

Thanks a lot!

Focus stuck in TreeList

I have a TreeList that contains a TextBox and an accompanying update button.

If I change the textbox and click the Update button, everything works as expected.

If I change the textbox and press Enter, the focus is stuck in the TextBox. When I then click a (submit)button outside of the TreeList, no event is triggered. If I first click anywhere outside the TextBox and outside the button and after that click the button, the click event is fired.

Of course, this problem only occur in IE (9), not in Firefox.

Anyone with a clue to why this happen?

<telerik:TreeListTemplateColumn HeaderText="Quantity">

<ItemTemplate>

<asp:Panel ID="Panel_Quantity" runat="server" DefaultButton="RadButton_UpdateCart">

Paging based on groups in Radgrid

Hi,
Our company has purchased the licensed product of telerik and would like to have some answers for the below query.

We are not able to implement paging on the basis of groups. For example we have 5 groups and have 10 rows in each group then if we set page size to 4 then first 4 groups should be displayed and 5th group should be displayed on 2nd page. But what happens is that only 4 rows of Ist group is displayed and 12 page numbers were created.

We have to implement paging based on groups instead of total records in the groups.

Please help. Its urgent.
