    Hi there:

    First of all Congrats for the new Design and performance of Telerik Forums :D you're great guys.

    Now, my problem jejeje. I've been using radpanel bars and I'm trying to customize their styles with the Telerik theme builder. I've localized the collapse and expand images in the element tree:

    ------RadPanelGroupElement (Properties: GroupCollapseExplorerBarImage, GroupExpandExplorerBarImage)

    At the last Element I've found those images, but even when I changed them, nothing happened. I don't know if those are the correct images that I've need to change.

    Could you help me with that issue?

    Hi David,

    Thank you for the nice words about the Forums - we are actively working on their next version I am sure you will enjoy the improvements that we will implement.

    I'm sorry for the inconvenience you have experienced using RadPanelBar. It seems that the caption images for expand/collapse are hard coded and I won't be able to provide you a solution, or even a work-around. However we will have a SP release next week and I will do my best to fix this issue and make it possible to change the expand/collapse image through the VSB tool or by using the control's API.

    Please let me know if there is something else regarding RadPanelBar.

    Kind regards,

    Hello Mira,

    Thank you for your interest. Unfortunately, this issue has not been addressed yet. Our team apologizes for the inconvenience.

    Nevertheless, I managed to produce a workaround for this case. The only way to apply custom images to RadPanelBarCaptionButtons is to set their Image property each time the RadPanelBarGroupElements have been expanded or collapsed. This will also allow you to customize the image size, location, and ImagePrimitiveAngle. For further information, please refer to the attached sample project.

    I hope this is helpful. Our team apologizes once again. We will address this issue in the future releases. Please, let me know if the provided workaround is convenient for you.

    I'm having a similar issue with the asp ajax RadPanelBar control.

    I want to change the icon shown on an expandable panel for its different states but cant see how this is done. I've even visited the Telerik Visual Style Builder site (which I appreciate is only Beta) and while the icon is shown in the style, it can't be edited. Is the ability to change this icon in the list of changes scheduled for this control?

    Found it...


    However, I'd still like to know how to hide the default arrows on the right?

    Hi Karl,

    Please, add the following css to hide the expand arrows of the panelbar items:
               display: none !important;

    All the best,

    Can the images (up and down arrows on the right side of the panel bar) be changed yet in the new version?

    Hello Michael,

    Yes, by using the css class selector below you can change the expand/collapse image:
    div.RadPanelBar_Office2010Silver .rpExpandable span.rpExpandHandle,
     div.RadPanelBar_Office2010Silver .rpExpanded span.rpExpandHandle {  
        background-image: url("PanelBar/Expandable.png"); 

    You can also find the image sprite (as an attached image) of the expand/collapse arrow that is applied in general to a RadPanelItem.

    Can you please tell me how to shift Expand/Collapse images to the left hand side instead of right (the default position of Expand/Collapse images).

    Thanks and Regards,
