What I am trying to do is :
On Click of "Details" button in Grid i want to make "Pane_TxtContacts" visibility to false & "Pane_NotesSection" visibility to true. And On "Edit" Click i am having Inline Edit & nothing to be done in respect with visibility.
So to attain this i put this in ajax manager. Aspx code for that is as below:

<telerik:RadAjaxManager runat="server" ID="ajax_manager" OnAjaxRequest="ajax_manager_AjaxRequest">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="Grid_contacts">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="Grid_contacts" LoadingPanelID="RadAjaxLoadingPanel1" />
                        <%--<telerik:AjaxUpdatedControl ControlID="Splitter_bottom" LoadingPanelID="RadAjaxLoadingPanel1" />--%>
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="ajax_manager">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="Grid_contacts" LoadingPanelID="RadAjaxLoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="Grid_contacts">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="Splitter_bottom" LoadingPanelID="RadAjaxLoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="btn_Save">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="Splitter_bottom" LoadingPanelID="RadAjaxLoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="btn_Cancel">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="Splitter_bottom" LoadingPanelID="RadAjaxLoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="LinkButtonShowUpload">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="LinkButtonShowUpload" />
                        <telerik:AjaxUpdatedControl ControlID="UpdateImagePanel" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="BtnCancelUpload">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="LinkButtonShowUpload" />
                        <telerik:AjaxUpdatedControl ControlID="UpdateImagePanel" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>
        <telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1" Skin="Vista" />

All works fine for "Details" with this code. But when i Click on Edit it does not result correctly showing error "Sys.ArgumentException:Value must not be null for Controls & behaviors. Parameter Name:element".
And,
When i remove the following statements from ajaxmanager than "Edit" works well but details doesn't
<telerik:AjaxSetting AjaxControlID="Grid_contacts">
                    <UpdatedControls>

Hello,

Testing a similar scenario as the described one, a javascript exception was thrown due to the fact that RadGrid initiated an internal command from a button column and its parent control was then hidden with Display = false;

Try this scenario to see if the exception is still thrown. Do not make RadGrid hidden after an event it has thrown. You can instead have an external control update both RadPanes. See if this fixes  the problem.

Also check your RadAjaxManager settings. You can try replacing RadAjaxManager with a RadAjaxPanel around the RadSplitter and see if you still get the exception.
