I believe I've discovered a fairly severe error in the Rad Editor. I discovered this while using DNN 5.6.1, but the Rad Editor demo on this website behaves the same way. This bug appears in Firefox, but not in Internet Explorer.

Set the editor to use <p> paragraph tags instead of <br> break tags, by setting the following:
<property name="NewLineBr">false</property>

Within the editor, add an image to the blank content area.
The image should display correctly. Press the Enter key to create a new paragraph after the image, and the image should "disappear."

If you inspect the source code, you should notice that the image tag has been replaced by the  

Again, this bug seems to only be in Firefox.

How to add a ContextMenu item dynamically

Hello telerik team,
I want to implement such a function: When right click different element , add different contextmenu item to the bottom of original menu items and can fire some costomer method when clicking it.

For Example:
Now, I have two elements, the one is <input type='text'> , another is <input type='radio'> , when right click the first one, add a menu item called "Edit textbox" to the contextmenu, when click it, run the customer function "OpenTextEditWindow", and the second one is similar with the first one. How should I do?

I am looking forward to your reply

Hide filters depending on item count

Is it possible to hide the filter controls depending on the item count of the RadGrid, or if the pager is shown?

Ideally I don't want to show the filter boxes if the results already fit on one page, has anyone done this before?

Cheers

Jon

RadListBox + CheckBoxes + Validation Callout Extenders

Hey all,

A common subject is how to validate that a RadListBox with CheckBoxes="true" have at least one item checked (not selected).

Here is a post that explains a good solution to make it work.
http://www.telerik.com/community/forums/aspnet-ajax/listbox/radlistbox-checkboxes-true-and-requiredfieldvalidator.aspx

The solution above says we need to remove the ControlToValidate from the CustomValidator attached to the RadListBox.

This would work great unless you happen to use validation callout extenders to show a tooltip over invalid fields. In this case, in order to position the tooltip, the validator must have a _controlToValidate property.

So how do we get the RadListBox to work with validation callout extenders? In our case we dynamically add our validators to the page with extension methods. I suppose we could add a custom attribute to the validators that would be like ControlToValidate2="rlbStates" and the callout extender could check this property if ControlToValidate was null...

Any ideas that are more "built-in" and less "hacky"?

Thanks!
Thad

Microsoft JScript runtime error: 'Sys.WebForms.PageRequestManager' is null or not an object

Hello,

I'm trying to get File Explorer hooked up to a SQL Server 2008 database, and I can't get past this error. It displays the folders, and I can see it hitting the database and returning records, but when the page loads it throws this error:

Microsoft JScript runtime error: 'Sys.WebForms.PageRequestManager' is null or not an object

Does anyone have a solution for this error? Also, the files are being saved as binary streams, so if anyone has any code on how to convert these back into files using File Explorer, I'd be in much gratitude.

Thanks,

Scott

Centering RadDock's Titlebar text.

Hi Telerik,

This should (hopefully!) be really simple.

I have this:

.RadDock .rdTop{text-align:center;}

This does basically what I want -- it centers the title of the RadDock. But, when the calculation is made on where to center it, it takes into consideration the far LHS of the RadDock to the start of the first command on the RHS. This is causing my text to be displayed off-center compared to the content in the RadDock.

Is there a way to do something like text-align:center text-shift-right: 38px? I tried using text-indent, but it seems to indent how far the icons are from the RHS and not the text itself.

Thanks!

Self opening window

Hi

I open my window in code behind using VisibleOnPageLoad and AjaxRequest. I also set a navigation url in this ajax request. When I want to close window I call javascript function on page which was loaded as content of the window. Function look like this:


<script type="text/javascript">
    
    function GetRadWindow() {
        var oWindow = null;
        if (window.radWindow) oWindow = window.radWindow;
        else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
        return oWindow;
    }
 
    function CloseAndRebind() {
        GetRadWindow().BrowserWindow.selectionFinalize();
        GetRadWindow().Close();
        return false;
    }
    
</script>
>

But when window is closed, it opening itself.
