Is it possible to set up a different theme for only the detail portion of the hierarchical grid? There does not appear to be any way in the existing gridview theme to specify cell colors and borders, row properties, etc. for the contents of the detail portion of the grid. When I change them in the existing grid theme, they do not apply to the child portion, even when I change them in the Visual Style Builder's RadGridView GridDetailViewRowElement or it's subelements. (Other changes I made in the theme do apply, so I am certain the theme is found properly). Ideally I would like the child rows to be styled differently from the parent rows, and so far the only way I seem to be able to affect them is through the CellFormatting event, but that is painful. Thank you for your time.

Problem with ExamplesVB demo

Have recently installed as trial Telerik Winforms Q2 SP1 2008. When I load the ExmplesVB demo into VS 2008 I receive in the region of 40+ errors and well over 200+ warnings. Same when I rebuild. I can run the compiled executable if I choose last working build even though there never was a correctly compiled build.
The rebuilt demo seems then to run in much the same way as the demo that loads at the end of the package install. There are however the same problems or errors. These are mainly with Themes which gives an exception and doesn't work and also with the media player. Most of the errors produced in the build are undefined property errors related to the Media demo.
Is there an update to the demos which works?
It looks like the demo is not completely finished and debugged.
Any help much appreciated.

Export To CSV error

When one of the values of a cell is "Department Stores", it errors out. Initially I thought it might be the space, but other values with space work fine. I have a cellformating event handled, but it does not get there. In other words, it errors out before the event fires

Here is the stack trace

System.NullReferenceException: Object reference not set to an instance of an object.

at Telerik.WinControls.UI.Export.CSV.CellElement.EscapeQuotesInValue()

Getting Height of innerControl

Hello,

I meet difficulties to autoresize my Pageview (in explorerBar mode)
I add several PageviewPage inside, and I would like to get the inner control container height in order to autoresize my page view.

When Pages are collapsed, I would like to set my pageview's height
(see attached picture collapsed.png)

I put autosize mode of my PageView à true.But it's not autosizing.
I tried the RadPageViewExplorerBarElement as children[0] of my pageview. But the autosize mode is not the good one too.
I also tried the RadPageViewContentAreaElement but not working.

What is the container inside my pageview which contains the RadPageViewPages?
This container is autoscrolled (my page view is not autoscrolled) and seems autosize.
We can see the vertical scroll of this container on picture container.png (yellow painted).
What is this container? I really need to get his height.

As far I know, it's not the pageview, explorerbar, contentArea neither.

Maybe you know a better way to autosize my pageview following the collapsed and extand event?
Please let me know.

Thanks a lot for help.

Regards

PageView
