    Dear Telerik team I request you to please help me in resolving below issue as I am not much familiar with Telerik and Sharepoint environment. I posted my issue in other forums too but did not got any solution.

    There is a "RadGrid" inside which there is a "RadComboBox" and a "asp:Button" next to it.
    This RadGrid is NOT ​​inside "RadAjaxPanel" due to some reason.
    When user key-in any text in RadComboBox and click on Button, only then the searching (related to key-in text) is started in RadComboBox and displayed in a DropDownList.

    Now, when user type/key-in any text in RadComboBox and click on Button, then the related data binds to DropDownList of RadcomboBox but the DropDownList appears to stick at the bottom of the page and the whole page scroll shifts to half of the page.
    and When I click outside of DropDownList then page becomes normal & DropDownList get closed. 

    Please let me know why is this happening when I DONOT put RadGrid inside RadAjaxPanel ?

    Below is the code I am using so far:

    <telerik:RadMultiPage ID="RadMultiPage6" runat="server" SelectedIndex="0" Width="100%">
        <telerik:RadPageView ID="RadPageView5" runat="server" Width="100%">                                                                            
        <%--<telerik:RadAjaxPanel ID="RadAjaxPanel5" runat="server">--%>
            <telerik:RadGrid ID="RGGSTAcCode" runat="server" AutoGenerateColumns="false" 
               ShowFooter="True" GroupingEnabled="False" ShowStatusBar="true"        
               AllowAutomaticInserts="False" AllowAutomaticUpdates="False" AllowAutomaticDeletes="true"
               OnNeedDataSource= "rggstAcCode_NeedDataSource" OnItemDataBound="rggstAcCode_ItemDataBound"                   
               OnInsertCommand="rggstAcCode_InsertCommand" OnDeleteCommand="rggstAcCode_DeleteCommand"
               OnUpdateCommand="rggstAcCode_UpdateCommand" EnableEmbeddedSkins="true" Skin="Outlook">
            <mastertableview commanditemdisplay="Top" autogeneratecolumns="false" datakeynames="AccountCodeID"
               insertitempageindexaction="ShowItemOnCurrentPage" ShowFooter="True" ShowHeadersWhenNoRecords="true">
               <CommandItemSettings AddNewRecordText="New" />
                    <telerik:GridEditCommandColumn UniqueName="imagebutton1" ButtonType="ImageButton"></telerik:GridEditCommandColumn>
                    <telerik:GridTemplateColumn UniqueName="AccountCode" HeaderText="Account Code">
                         <asp:Label ID="lblAcCode" Text='<%# Eval("AccountCode") %>' runat="server"></asp:Label>
                         <asp:Label ID="lblAcCode2" runat="server" Text='<%# Eval("AccountCode") + " - " + Eval("AccountDescription")%>' Visible="false"></asp:Label>
                         <telerik:RadComboBox ID="ddlAccountCode" runat="server" Height="200" Width="260" DropDownWidth="310"      
                           EnableLoadOnDemand="True" OnItemsRequested="ddlAccountCode_ItemsRequested" EnableItemCaching="true" 
                           ShowMoreResultsBox="True" EnableVirtualScrolling="true" AllowCustomText="true" MarkFirstMatch="true"
                           Filter="Contains" HighlightTemplatedItems="true" CausesValidation="true" AppendDataBoundItems="true"
                           DataTextField="AccountDescription" DataValueField="AccountCodeID"
                           OnClientDropDownOpening="OnClientDropDownOpening" OnClientItemsRequested="OnClientItemsRequested">                                   
                         <asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click" OnClientClick="ButtonClicked()" UseSubmitBehavior="true" /> 
                    //Other columns
                    <EditColumn ButtonType="ImageButton" />
                 <PagerStyle AlwaysVisible="True" PageSizeControlType="RadComboBox" />


    //disable opening of RadCombo dropdown when click on left image of dropdown
    function OnClientDropDownOpening(sender, args) {
    if (sender.get_items().get_count() == 0 || sender.get_text() == "") {
    //hide RadCombo dropdown If the text area is blank
    function OnClientItemsRequested(sender, eventArgs) {
    if (sender.get_items().get_count() < 1 || sender.get_text() == "")


    protected void ddlAccountCode_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
            Session["Text"] = e.Text;
            Session["NumberOfItems"] = e.NumberOfItems;
            RadComboBox combo = (RadComboBox)sender;
            combo.ShowDropDownOnTextboxClick = false;
            combo.HighlightTemplatedItems = true;
        protected void btnSearch_Click(object sender, EventArgs e)
                GridEditableItem editedItem = (sender as Button).NamingContainer as GridEditableItem;
                RadComboBox combo = (RadComboBox)editedItem.FindControl("ddlAccountCode");
                //clear the previous items on every new search
                combo.OpenDropDownOnLoad = true; // opens dropdown of RadComboBox on button click
                combo.HighlightTemplatedItems = true; // to highlight the searched text
                //Code related to search in RadComboBox
            catch (Exception ex)

     Please note that I am using Sharepoint in my application.

    I tried all possible ways to solve this issue like: 

    1.  MaintainScrollPositionOnPostback="true"

    2. Setting the RadGrid scroll position in ClientSettings tag

    3. used few javascript code 

    but nothing worked in my scenario. Please somebody help me, I am facing this issue since long and I have to complete it at the soonest.

    Thanks in advance.

    Added back the RadAjaxPanel for RadGrid, and added the filtering logic in `StoredProcedure`, that I was doing before from code behind.<br/>
    i.e., removed below line of code from .aspx.cs page:

    //code related to search in RadComboBox
    DataView dv = new DataView(dt);
    dv.RowFilter = string.Format("AccountDescription LIKE '%{0}%'", txt);
    //--other code

    and added this logic in StoredProcedure query. Due to RadAjaxPanel, DropDownList of RadComboBox is aligned to its proper position and all is working fine now.

    Thank you
