Radcombo box options are not moving along with the radcombobox while scrolling

[Pratap]

Hello Telerik team,

I have a weird problem and it became a show stopper for me.
Problem: "Rad combobox options are not moving along with the rad combobox while scrolling"

RadCombobox is in <asp:Content which is in child page. and the <asp:Content is place in a rad splitter.
Below gives  clear idea about  the layout i am using.

Master Page==>Rad Splitter==>RadPane==><asp:Content==>RadComboBox

scrollbar is there for RadPane.
Please provide me a solution asap.

Thanks in Advance.

Hi Pratap,

The error that you receive "Sys is undefined" indicates that the MS Ajax framework is not loaded. The most possible reason for this problem to occur is if you have registered the JavaScript before the script manager control on the page. Could you please try to place the JavaScript of the forum thread linked above below the declaration of the ScriptManager control on your page? If the problem still occurs, could you please provide a sample page reproducing the problem?

Hi Dobromir,
Thanks for your suggestion and it really worked but this  hideDropDown() function is not working and its giving error
"Object doesn't support this property or method".
I am using classic rad controls. Please give me the alternative function to collapse/close radcombobox options when i have radcombobox client object.

Thanks

Hi Pratap,

The client-side method for Classic RadComboBox is HideDropDown() (note the capital H). Also, the approach to get reference to the client-side object of classic control is a bit different - instead of using $find("ControlID") you need to use the following code:
var combo = <%= RadComboBox1.ClientID %>;
Detailed information regarding RadCombo Classic client-side API is available in the following article:
http://www.telerik.com/help/aspnet/combobox/combo_client_basics.html

Also, if you are using RadSplitter Classic you will need to modify the code from the above mentioned forum thread to use the correct methods as well. Here you can find the client-side API of RadSplitter Classic.

Kind regards,
