    Hello,

    I was having a lot of trouble getting the radtooltip to work correctly in a customwebcontrol (source is appended). For IE all is working ok. For Firefox and Opera there is an issue. When I set the alternatetext property of the image the tool tip won't show in both browser. When it's empty it is al working ok. As a workaround i leave the alttext empty although it's against our policies. You know an other solution for this problem?

    Thanks,
    Carol

    Hi Carol,

    I believe the alttext property is specific to IE and not supported by other "standards based" browsers.  You should use the "Title" attribute which is supported by all and this should cure your problem.

    regards
