Updated Controls Appear on a New Line


Product Progress® Telerik® UI for ASP.NET AJAX


What can I do when updated Telerik UI for ASP.NET AJAX controls appear on a new line?


Controls render on a new line when they are added to the AjaxManager settings. The reason for this behavior is that the AjaxManager dynamically inserts UpdatePanels around the updated controls. The UpdatePanel is, by default, rendered as a <div>, which is a block-level HTML element and leads to changes in the layout.


The AjaxManager exposes the UpdatePanelsRenderMode property which enables you to control the render mode of the dynamically inserted UpdatePanels. You can define the UpdatePanelRenderMode property for each updated control and set both properties to either Block or Inline, which will determine whether the wrapping element will be displayed as a block or as an inline element.

When working with the AjaxManager, you can use the global UpdatePanelsRenderMode property to set the render mode for all generated UpdatePanels to inline or to block, or to set it explicitly for a particular UpdatedControl.

The Inline render mode will ensure that the layout will not change when the AJAX settings are added. Otherwise, the AjaxManager will persist the default render mode of the UpdatePanel.

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" UpdatePanelsRenderMode="Inline">
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                <telerik:AjaxUpdatedControl ControlID="Label1" UpdatePanelRenderMode="Inline" />
                <telerik:AjaxUpdatedControl ControlID="Label2" />
