    I have a radbutton control in a radgrid that blinks when I mouse over or mouse out.
    The project is using Telerik.Web.UI version 2012.1.411.35 and is running in DNN v6.2.2.
    Looking at the Google Chrome development window; it seems like the image is being reloaded but before it is reloaded an about:black page is shown. (see attached image)
    Any idea why it would be going back to the server to get this image and why about:blank is displaying?

    <telerik:RadButton ID="INFO" runat="server" AutoPostBack="False" CausesValidation="False"
                                        Height="20px" OnClientMouseOver="infoRow"
                                        Text="" UseSubmitBehavior="False"  Width="36px" Image-ImageUrl="/images/i_info.png" Image-EnableImageButton="True" rowid="" Image-IsBackgroundImage="True">
                                   </telerik:RadButton>


    Thanks

    Hi Michael,

    Most probably the blinking effect is caused by a problem with caching the image of the RadButton. Please check if the issue persists when you specify the button's background image by creating a CSS class that sets the image as background via the background CSS property and passing the name of this class to the CssClass property of the RadButton.
