RenderMode Inline ignored for panel with multiple controls

Good afternoon,

I am using ASP.NET AJAX version 2023.3.1010.45,

I have a page with a ComboBox and Grid. By choosing an Item in the ComboBox and clicking a Button, it will locate the Item in the Grid. If an Item is inserted into or deleted from the Grid, the ComboBox needs to update. Both controls have the same ObjectDataSource as their data source. This is why they share an Ajax Panel.

I am using a RadAjaxManager and RadAjaxLoadingPanel as follows (setting UpdatePanelsRenderMode to Inline):

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" UpdatePanelsRenderMode="Inline">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadComboItems">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridItems"/>
                    <telerik:AjaxUpdatedControl ControlID="RadComboItems" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="RadGridItems">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridItems" />
                    <telerik:AjaxUpdatedControl ControlID="RadComboItems" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default" BackgroundTransparency="30" RenderMode="Lightweight">
    </telerik:RadAjaxLoadingPanel>

The ComboBox and Grid appear in the same RadAjaxPanel (also with RenderMode Inline):

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1" RenderMode="Inline">
    <label for="RadComboItems">Input/Select Item:</label>
    <telerik:RadComboBox ID="RadComboItems" runat="server" Height="200px" Width="200px" DataSourceID="odsItems" EnableVirtualScrolling="true" DataTextField="ItemId" DataValueField="RowNum" EmptyMessage="--Select a value--" RenderMode="Lightweight" EnableAjaxSkinRendering="true">
    </telerik:RadComboBox>
    <telerik:RadButton RenderMode="Lightweight" runat="server" Text="Select" ID="btnFindItems" OnClick="btnFindItems_Click" EnableAjaxSkinRendering="true" />

    <telerik:RadGrid ID="RadGridItems" RenderMode="Lightweight" runat="server" AllowPaging="True" DataSourceID="odsItems" AllowSorting="True" AllowAutomaticUpdates="True" AllowAutomaticInserts="True" AllowAutomaticDeletes="True" OnUpdateCommand="RadGridItems_UpdateCommand"                                    OnItemDataBound="RadGridItems_ItemDataBound" OnItemCommand="RadGridItems_ItemCommand" OnItemDeleted="RadGridItems_ItemDeleted" OnItemInserted="RadGridItems_ItemInserted" OnItemUpdated="RadGridItems_ItemUpdated" OnPreRender="RadGridItems_PreRender" CellSpacing="-1" GridLines="Horizontal" OnDetailTableDataBind="RadGridItems_DetailTableDataBind" AllowFilteringByColumn="true" OnInfrastructureExporting="RadGridItems_InfrastructureExporting">
....
....
    </telerik:RadGrid>
</telerik:RadAjaxPanel>

When the page first renders, the ComboBox and Button render as expected:

<div class="RadAjaxPanel" id="ctl00_maincontent_ctl00_maincontent_RadComboItemsPanel" style="display: inline;">

Once the Button is pressed though, the rendering changes to Block:

<div class="RadAjaxPanel" id="ctl00_maincontent_ctl00_maincontent_RadComboItemsPanel">

Is there anyway to prevent this from happening, without having to specify this on the page:

    <style type="text/css">
        .RadAjaxPanel
        {
            display: inline !important;
        }
    </style>

Kind regards,

Richard

Add Load on Demand radcombobox within a radgrid

I was curious if there was a way to add a radcombobox with load on demand abilities within an exisiting radgrid. I really just need to have it that when you start typing it will then populate any items that start with the letter/numbers you are typing dynamically. For example, if I typed Batt it would autofill Battery or if I had done Serial Number it would populate all that apply. I have seen it outside of a grid but not within. In the picture below would like to have the asset_type autofill options from database that are in the asset_type column. Any examples would be great.

SetFocusOnError not working for combobox

Hey guys,

I'm finishing setting up some validation controls on a page for a client. I'm having some trouble with getting RadComboBox to jump up when validating. I'm using SetFocusOnError="true" and all other element's on the page are functioning correctly including other telerik controls.

I did find an old forum post with an employee saying that there was an error on telerik's end but, it's from 2007 so it may not be valid anymore.
http://www.telerik.com/community/forums/aspnet/combobox/validation-focus-not-setting-on-combobox.aspx

<telerik:RadComboBox ID="FrmReferredBy" runat="server" AllowCustomText="false" CausesValidation="false" /><asp:RequiredFieldValidator ID="FrmReferredByValidator" runat="server" Text="*" ControlToValidate="FrmReferredBy" Display="Dynamic" SetFocusOnError="true" />

If you have other questions or need more code just let me know. Thanks!

Peace,
Spencer

RadComboBox AutomaticLoadOnDemand issue

We have a serious issue when using this feature, following code generates attached error. It occurs when scrolling or clicking the "Show more results"

                                      <asp:SqlDataSource ID="sds_geneesmiddel" ConnectionString="<%$ connectionstrings:lef %>" SelectCommand="select Left(Naam, 70) as Naam, id from geneesmiddel order by Naam" runat="server"></asp:SqlDataSource>

                                                    <telerik:RadComboBox DataSourceID="sds_geneesmiddel" DataTextField="Naam" DataValueField="id"
                EnableAutomaticLoadOnDemand="true" ShowMoreResultsBox="true" EnableVirtualScrolling="true"
                ItemsPerRequest="10" Width="100%" Height="150px" Filter="Contains" EmptyMessage="Typ de naam" DropDownAutoWidth="Enabled" ID="rcb_geneesmiddel" runat="server">

                                                    </telerik:RadComboBox>

This is something I have to solve today, please react urgently.
