Hello,
In the page_load event I set the RADEditors on that page to enabled = false if some conditions are fulfilled. The reason is that sometimes the user is only allowed to read the content of the editors. The content comes from the database.
The problem is that the lay out of the editors is gone, only the content is shown and because there are no scroll bars, the height of the editor is too big. How can I get scrollbars around the editors or keep the normal lay out in this situation? I use RADControls for ASPNET AJAX Q2

Thanks in advance,
Barbara

Hello,

I am using the RadEditor is a Publishing Pages scenario and it workd beutifully. However, when I use a Dataview webpart to trieve field content entered with the "AllowSpecialTags" attribute enabled The page renders the following markup;


I realize this markeup must be encoded somehow so that SharPoint will not strip out special tags, attributes, and scripts. So is there a way, using a dataview webpart, to display the content entered using the RadEditor control?

Thank you in advance, any help is appreciated.

Recently I noticed that under IE7 if I ctrl+click dates within a radcalendar supporting multiple selection a new tab window will open as if a link was clicked.  I do not get this when using FF 3.5, but unfortunately most of my users are in IE 7.

As an example, go to the Telerik Calendar "First Look" page.  If you Ctrl+click on the calendar, a new tab should NOT appear.  Now, unclick any of the check boxes shown.  Ctrl+click a new date and a new tab DOES appear.

Now, I have only noticed this under IE7, but it may occur in other versions of IE7.  I am looking for a way to stop this behavior as many users commonly use the Ctrl+click to select multiple dates (even though it is not required with this control).

Any suggestions?

Hi,

I'm using the editor in lists and have some columns defined as Rich Text and some as Enhanced Rich Text.  I want to be able to restrict the Enhanced Rich Text (which will be used just for simple HTML) much more than the Rich Text columns in terms of toolbar options.  However, if I remove the BasicToolBar buttons they disappear from the Rich Text as well as the EnhancedRichText toobars.  Essentially, I would like only the EnhancedToolbar to appear for thet EnhancedRichText and only the BasicToolbar for the standard Rich Text.

Is there a way of doing this?

Thanks.

Has anyone encountered an alert 'Cannot write to the target folder'? We are and are puzzled. If anyone can shed some light on this, that would be great as I have a client yelling at me. Thanks.

Hi,

I have a radgrid for which allowcolumnfiltering will be managed by a radio button Yes. if the user clicks on Yes then filtering on column should be enabled. I am facing an issue when custom filtering on column is on by clicking on radio button Yes.

When I give value to a column and click on filter button, the filter options(EqualTo,NotEqualTo....) is display as text on the response. I made EnableAjaxSkinRendering property to true but still the issue persists.

Everything works perfectly when i remove radiobutton updates from RadAjaxManager.

Please find code below.

thanks,
Mahesh

Dear,

I have a problem with Internet Explorer 7 using in the same page the following controls :

RadWindowManager
RadAjaxManager
RadGrid

For Example, if I do a sort in the grid, it appears on the top of the page an empty space.

If I remove a control RadWindowManager or RadAjaxManager, it is all right.
