RadCombobox pronlem with client callback

[Ganesh]

Hi All,
            in my application i have
one checkbox,
one button &
one RadCombobox

when we check the Checkbox & click on button ,the RadcomboBox's visible property will set to false.

& when we uncheck the Checkbox & click on button ,the RadcomboBox's visible property will set to true.

i.e radComboBox keeps appearing & dissappearing.

in this scenario i am getting the following error,

the target 'xyz' for the callback could not be found or did not implement IcallbackEventHandler.

please help me to solve this.

Thanks in advance.

Hello Ganesh,

This is indeed weird. We could not stumble upon such a problem at our side. I suggest that you try to populate the combobox items from a webservice. This should solve the problem. An example can be seen at:
Populate from WebService

Hope this helps.

Kind regards,

Hello,

I am also getting the same error message. In my case I am using RadToolTip to open a user control in a modal popup. My RadComboox reside in the user control. I get the error as soon as I type something in the combobox or try to expand it.
