how to replace default textbox from filteringItem

[Hiren]

I want to replace default textbox with radcombo and want to remove filter icon. I got samples for google like filtering but that sample is working when there is no default gridboundcolumns defined and datafield is not attached. I want to retain my design time columns and want to those Datafields and want to apply google like filtering.

can anyone tell me how to replace textbox control with radcombo [google like filtering], below is sample grid which i am using

<telerik:RadGrid ID="rgdRefer" runat="server" GridLines="Vertical" AllowSorting="True"
                       AllowPaging="True" AutoGenerateColumns="False" EnableEmbeddedSkins="false" Skin="CustSkin"
                       PageSize="5" CellSpacing="0" OnItemCommand="rgdRefer_ItemCommand"
                       OnItemDataBound="rgdRefer_ItemDataBound" Width="1020px" OnColumnCreating="rgdRefer_ColumnCreating"
                       AllowFilteringByColumn="true"
                       onneeddatasource="rgdRefer_NeedDataSource">
                       <GroupingSettings CaseSensitive="false" />
                       <SortingSettings EnableSkinSortStyles="false" />
                       <ClientSettings>
                           <Scrolling AllowScroll="true" UseStaticHeaders="true" ScrollHeight="180px" />
                       </ClientSettings>
                       <MasterTableView AllowNaturalSort="false" DataKeyNames="Id" Width="100%">
                           <Columns>
                               <telerik:GridButtonColumn HeaderText="Select" UniqueName="ibtnEdit" ImageUrl="~/App_Themes/BDefault/images/select_icon2.png"
                                   ButtonType="ImageButton" Visible="false" CommandName="EditUser" />
<telerik:GridBoundColumn HeaderText="Custom Field 12" DataField="CTA_5" UniqueName="CTA_5"
                                   SortExpression="CTA_5" Visible="false" />
                               <telerik:GridBoundColumn HeaderText="Custom Field 13" DataField="CTA_6" UniqueName="CTA_6"
                                   SortExpression="CTA_6" Visible="false" />
