RadGrid Paging on Multiple Lines but should be on a single line

I have a basic RadGrid control on a page. I only set the grid property AllowPaging="True" and the only Pager Style is <PagerStyle Mode="NextPrevAndNumeric" />. When the form loads up the paging is showing on 4 separate lines. I just want it to be on one line like all of the samples. Any ideas why this is happening? Do I need to apply CSS?

Filtering Dynamic RadGrid

I am trying to add Excel like filtering for a dynamic RadGrid. I found this example that shows filtering with client-side binding: http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/basic-filtering/defaultcs.aspx. However, I do not have GridBoundColumns because my RadGrid is dynamic. How do I go about adding Excel like filtering if I do not know the columns beforehand? Please show an example.

Thanks

RadAjaxManagerProxy - master and content page the dropdownlist shows twice after adding it in RadAjaxManagerProxy.

RadAjaxManagerProxy - master and content page the dropdownlist shows twice after adding it in RadAjaxManagerProxy. for information see line code - 63

if i dont add it the selected index change doesnt fire/change.

what to achieve - when user change the dropdown from master page (all the way right top in video name - select framework, the content page information should be refreshed without full page refreshed( i have achieved it using RadAjaxManagerProxy). when i select the tab Rating model and click on add new record-> change perspective, it doesnt update the relevant text box,autopostback is not working if i dont add in Radajaxmanagerproxy.

if i add the line 63 and so on, it shows controls twice.

why and how to fix it.

Search in RadComboBox (inside RadGrid) on asp button click

Hi there is a RadComboBox inside EditItemTemplate of RadGrid along with a Button.

I am using _ItemsRequested event just to do the search in RadComboBox but not loading the whole list into it on click of RadComboBox.

Current functionality is:
When user click on textarea of RadComboBox, type/key-in any thing, then only the Combo binds the searched related Items into it.

Now I want to get below functionality on button click:
when user click on textarea of RadComboBox, type/key-in any thing, and click on button..then only the Combo shall bind the searched related Items into it.
