the target for the callback could not be found or did not implement icallbackeventhandler

[Eric]

I am receiving the the following error on the  rad combobox.  The combobox is contained within a tooltip.  The actual tooltip is a user control.  I am also using a master page.  The tooltip works fine without the combobox.

When ever I click the combo box, in the tooltip, you see the combo box expand behind the tooltip and the following error pops up.

Attached is the error message screenshot.

I can't seem to get any rad control to work in the tooltips without showing behind the tooltips.  The combo box is the only one that has caused an error.  The other rad controls just show behind the tooltip without errors.

I have the same rad combobox on a child page and it works fine....  except that as soon as the dropdown is shown, the textbox looses focus.

Below is the user control code that I have in the tooltip.

Please let me know what I'm doing wrong and I thank you in advance for any help.

Thanks,

-eric

Hi Eric,

When content has been loaded on demand in the RadToolTipManager it is inside an update panel and the scenario is quite complex internally. Currently client callbacks are not supported and this is what the combobox uses for its load-on-demand mechanism. This improvement is already logged in our PITS and you can follow, vote and comment in this URL: http://feedback.telerik.com/Project/108/Feedback/Details/119654.

Regarding the appearance - it is most likely caused by the z-index of the different controls and you can see the default values here: http://www.telerik.com/help/aspnet-ajax/controlling-absolute-positioning-with-zindex.html.
You can either use the approach given there to modify them, or use CSS overrides (in the latter case do examine the actual popup elements to get the correct class).

I was able to solve the same issue by moving out the RadSearchBox control out of a container control.

I cannot find the page from the given PITS URL. Has this been fixed (I mean.. improved)?

Hi Kyle,

The PITS was discontinued in favor of the Feedback portal and you can find the feature request here: http://feedback.telerik.com/Project/108/Feedback/Details/119654 so you can vote, comment and track its status. I am sorry to say that this feature has not been implemented yet. If you need it immediately, please open a support ticket and I can offer some guidance but the process is not very easy and we cannot guarantee proper functionality.
