Hi,

We're using the RadEditor in the administration area of our custom CMS, and we'ld like to be able to specify multiple files for the ContentAreaCssFile property:

1. the main website skin CSS file of the target website, so the (text) styling in the editor looks familiar to the person editing the content
2. a temporary CSS file just for the editor itself, eg. to specify a temporary visible (dashed) border for a DIV element which is inserted using a custom dialog

How do we accomplish this?

Best regards, Marja

I'm trying to fix up a page so that the RadGrid has working filters. This has been fine on other pages, but the presence of a GridBoundColumn with a join in the DataField, and a GridCalculatedColumn is making this difficult.

My findings:
 - Originally, EnableLinqExpressions ("ELE") was set to "false", but this meant that filtering didn't work
 - ELE = false and removing the Calculated field --> Filtering works
 - ELE = false and removing the Joined filed --> Filtering is broken
 - ELE = true --> I get a Telerik.Web.UI.ParseException: ')' or ',' expected. No clear column as the culprit, error seems derived from the GridyDynamicQueryable.Select()
 - ELE = true and removing Calculated field --> Filtering works
 - ELE = true and removing Joined field --> Filtering works

And my boiled-down code:

It seems to me that there's an error with the code of a filtering function when a Join and Calculated field are being used. I also don't want to have to denormalise my database, but if I can't find a resolution soon, I'll have to do that.

Hi,

When using the grid to input content through the edit form templates for example.
How are people validating the input against script attacks and such.

Cheers,

Jon
