[Solved] dropdownlist doen't come up ?

[Elton]

Hello Telerik

I try to cancel the postback from combo box onselectedindexchange, because for some value I need post back and some not.

What I m doing is :

in ajax OnInitializeRequest event I do:

args.set_cancel(true);

This does stop the post back but the problem is it also stops all combo boxes in the page! the drop down of the combo box can not dispay.

Any idea on this?

Regards,
Elton

Hi Elton,

What about hooking on the OnClientSelectedIndexChanging event of the combobox and canceling the event there by calling the event arguments' set_cancel(true) method? This will stop the postback.

Hope this helps.

I have similar problem. Once post back start the drop down box can no longer be accessed. The auto complete  feature works but drop down list no where to be found. This only happens on certain system not sure why.

I have the same issue with a RadComboBox inside a WebUsercontrol that is inside an ajaxified Gid. When I click Submit on the usercontrol and validators fire as false the ComboBoxes stop working. I can still pick items by using the arrows or customtext but the drop down is gone. I can only get it back by throwing a postback which i don't want to do. I think this is a bug I have tried almost everything to get the dropdown to open but its like its gone.
