    I have a RadComboBox that sits in a RadToolbar that when drops down over a HTMLPlaceHolder has z-order issues - in that the HTMLPlaceHolder text is over the ComboBox dropdown text. Is this a known issue being worked on?

    Hi Dennis,

    This is a limitation in the current version of the RadHtmlPlaceholder. It is caused by the fact that the HtmlPlaceholder control is rendered in the Html Page and sits above the whole Silverlight application. That is why it is displayed above all the Silverlight content ( popups also).

    For the moment the only workaround to this will be if you hide the html placeholder when you open the combobox dropdown.

    is there a way to reverse the direction of the combobox dropdown?  default behavior is to drop down or up depending on how much space is available, but is there a way to force it to drop up or down?

    Hi,

    I'm using Version 2010.2.924.1040 of the Telerik controls and have a z-order issue with the HTMLPlaceHolder control.
    When i open a RadRibbonBar which overlaps a HTMLPlaceHolder control the HTMLPlaceHolder control shows over the RadRibbonBar.
    Has this issues been corrected yet? Any workarounds?

    Regards,
    Mark.

    Hello MarkBr,

    There are still no workarounds for this behavior. As Valio explained essentially the RadHtmlPlaceholder is an IFRAME element that is positioned above the Silverlight plugin and therefore we cannot control its z-order.

    I hope this isn't a showstopper for you. Let us know if you need more info.

    Hello Tina,

    It actually is a blow since we have spent quite some time to display Reporting Services Reports in our Silverlight application.
    Our application is actually connecting to report server and then displaying the generated report in html format in the HtmlPlaceHolder.
    Everything is working fine except that the HtmPlaceHolder is displayed above the RadRibbonBar which holds our menus.

    Is there any other way to display Reporting Services Report in the silverlight application?

    Regards,
    Mark.

    Hello MarkBr,

    You can try using the RadRichTextBox control that has HTML support. I attached two sample projects illustrating how to display Html files in the RadRichTextBox. The second application illustrates how to use the RadBook to preview html files. I hope that will help you.
