Moving Dock to different Zone, hide Radchart and show image.

Dear Telerik,

Currently I have 4 different RadDockZone each with a RadDock in it. On the bottom of my page I have a RadRotator with 10 RadDockZone each with a RadDock too. Inside each RadDock I have the RadChart to display the chart from my SQL database. Currently I'm using these code to drag and exchange RadDock between zones, and it's working great.

I would like that whenever I drag a RadDock into the rotator, the dock would display an Image instead of the RadChart's graph. Each of the raddock should has its own image.The initial RadDock in the Rotator on page load only display the image too. Is this something possible to do using Javascript, or I have to do with code behind and autopostback?

I've been trying to figure out without success. Please help me on this problem.

Thank you,
Loc Huynh

RadToolBarDropDown Items Missing

I have the following definition for a RadToolBar:

<telerik:RadToolBarDropDown Text="Export Options">

<Buttons>

<telerik:RadToolBarButton runat="server" ImageUrl="~/_assets/images/report/excel.png" ToolTip="Export to Excel" />

<telerik:RadToolBarButton runat="server" ImageUrl="~/_assets/images/report/csv.png" ToolTip="Export to CSV (Raw Data Dump)" />

</Buttons>

</telerik:RadToolBarDropDown>

For some reason these items won't show up (see attachment). The parent RadToolBar instance is using the Windows7 skin, although I also tried the Vista skin and no luck there either. There is no data binding on this toolbar - all items are static and the RadToolBarDropDown in question is at the root level (inside the main <Items> collection). I'm on Q2 2011.

Thoughts?

Refresh Rad Grid's CONTEXT MENU on RadWindow Close

Hi All,

I am using the technique show in this forum to refresh a RadGrid on a RadWindow close:

http://www.telerik.com/community/forums/aspnet-ajax/window/refresh-radgrid-on-close-of-radwindow.aspx

This works like a charm. :) My challenge is, however, while the grid refreshes itself beautifully, the context menu targeting the grid "disables" itself. Specifically, when the user right-clicks, nothing happens at all.

When I refresh the page, the context menu "re-enables" itself, and I'm back off to the races.

To resolve this, I've tried to DataBind the context menu in the Code Behind (in the AjaxRequest procedure as show in the forum post above). But, that did not help.

So, I think my specific question is how do I "reactivate" a context menu targeting a RadGrid after I run the procedure shown in the forum post above?

Thanks you very much for any help that you can provide.

Jim

Line break does not clear current block element (unexpected behavior?)

When I enter text in the RadEditor for SharePoint 2010 (a page content field), highlight the text and select Heading 1 from the menu, and then press enter, the new line is still within the H1 element (and has similar styles applied).

I expected that the H1 element would be closed (unless I specifically extended it by pressing shift+enter).

I have demonstrated this behavior on my trial install of RadEditor for SharePoint (as well as on the Telerik demo at http://sharepoint.telerik.com/aspnet-ajax/web-parts/Pages/Content-Editor-Web-Part-using-RadEditor.aspx), in IE8 and Chrome 15. (Behavior is as expected in Firefox 7.)

Unfortunately, this is the same as the behavior of SharePoint 2010's default rich-text editor. I reported the behavior to Microsoft (see http://social.msdn.microsoft.com/Forums/en-US/sharepoint2010general/thread/49f4276d-c709-43ad-9ebd-e5fc44c1b4f4/), which they say they will address in a future update. This is the primary reason why I am evaluating 3rd-party rich-text editors.

Are there any workarounds for this behavior?

Change font color when editing.

Hi.

I need to load text to RadEditor from database that can be changed by user from website. The problem is that default text colour must be black, and all changes that user makes must be in red colour only. How can I achieve this? I tried to use something like

function OnClientSelectionChange(editor, args) {

editor.get_document().execCommand("ForeColor", false, "Red");

}

But in this case font colour changes to red event when user select some part of the text with mouse or with keyboard, and that is totally wrong. I also tried to handle "keydown" event for the content area, but in this case each symbol is wrapped by span tag, so I get something like

<span style="font: red;">r<span style="font: red;">e<span style="font: red;">s</span></span><span>

And this is incorrect to, also, it causes problems with performance in the case of long text. Could someone please help me with this issue?

Problem with 2011R2 upgrade

Hi,

I am having some troubles with the 2011 R2 version of the components. I was using the ones from the 2010R2 and it was working fine. But I got a few days ago the newer version and i used the upgrade wizard.
Once I tried to launch my app, my login page didn't have neither css nor javascript and I got that javascript error :

Erreur : La feuille de style http://url/Common.css n'a pas été chargée car son type MIME, « text/html », n'est pas « text/css »

That text says that the stylesheet found has a "text/html mimetype but is waiting for a "text/css" one

I also realised with firebug, that the css stream I got from the server was not a css file, but the entire html page. However, once I was logged in, everything worked well, and including when i logged out.

So I looked for what changes did the wizard and I saw that the runAllManagedModulesForAllRequests attribute set to true in the module section of the web.config (System.webServer -> modules) was the origin of the problem. Once deleted, it works well.

My question is, why do I get those problems with this attribute? Do I need it anyway?

Thanks for reply

Group collapses when entering edit mode

Hello,

When a header item is expanded and the user enters edit mode on any item under that header, the group collapses. After re-expanding the header, the item is in edit mode. Is this behavior by design? If so, is there a way (VB.Net) around it? Thanks!

Sorting on individual columns based on the same DataField value.

I have a RadGrid bound to a query result. One of the query fields is an Id value which I use as the DataField value in several GridBoundColumn columns. I've overriden GridBoundColumn.FormatDataValue so I can use the Id to look up an object in a session state collection. Depending on the column's HeaderText value, FormatDataValue returns different properties of the retrieved object.

This all works lovely, except sorting is based on the Id value, not on what's actually in the grid. Furthermore, the UI indicates that all the Id-based columns are the same, presumably because they have the same DataField value. In the attached screenshot, I clicked on the City column. I would expect Chicago to sort ahead of London and Washington, but the rows are sorted by Address Id and the UI shows all the Address Id-based columns as currently sorted.

How can I revise things to make sorting work as I would expect?

Code to reproduce the problem follows.

Please note: I'm not looking for an answer that says, "flatten your data before putting it in the grid." I understand that I could do that. Remember this is a trivial example of a much more complex application. I do not want to avoid the issue I've presented; I want to solve it.

Thank you kindly!
