I am trying to place a radscheduler as a user control on one of my pages, I am getting this error

script control 'RadAjaxManager1" is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptSescriptors. Parameter name: scriptControl.

it's weird because when I run my code on my local machine everything is honky dory, but once I move it to the server it no longer works.

any ideas on why this would be happening?

code:
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
......
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <%--//commentedout to seperate grid from scheduler
            <telerik:AjaxSetting AjaxControlID="RadGrid1">--%>
            <telerik:AjaxSetting AjaxControlID="RadScheduler3">
            <UpdatedControls>
                <%--//commentedout to seperate grid from scheduler
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" />--%>
                <telerik:AjaxUpdatedControl ControlID="RadScheduler3" LoadingPanelID="RadAjaxLoadingPanel1" />
            </UpdatedControls>

                    </UpdatedControls>

Hello,

I'm getting the same javascript error while integrating a RadGrid in RadScheduler.

I followed the advanced form customization guide (because my advanced form is more complex). I defined a custom user control in which there is a RadTabStrip with 3 tabs and inside one of them I integrated a RadGrid, with paging, sorting and filtering. The RadScheduler is defined in a user control that is the content of a masterpage, and it's ajaxified using RadAjaxManager (declared into masterpage but set using the Proxy inside the usercontrol). It is databound to a collection filled from a database, as well as the the DataTable bound to RadGrid.

Here is some excerpt from Master and content page to show Ajax, ScriptManager and RadScheduler settings:

Masterpage:

...

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="ScriptManager2" runat="server">

<Scripts>

<asp:ScriptReference Path="AdvancedForm.js" />

</Scripts>

</telerik:RadScriptManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"></telerik:RadAjaxManager>

...

<asp:ContentPlaceHolder ID="PlaceHolder" runat="server" />

...

</form>

</body>

Content page:

...

<asp:Content ID="Content1" ContentPlaceHolderID="PlaceHolder" runat="server">

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadScheduler1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadScheduler1" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" />

....

<telerik:RadScheduler ID="RadScheduler1" runat="server" ... >

<AdvancedForm Modal="true" />

<AppointmentTemplate>

...

</AppointmentTemplate>

<InlineInsertTemplate>

<scheduler:InlineInsertForm runat="server" ID="InlineInsertForm1" Mode="Insert" Subject='<%# Bind("Subject") %>'... />

</InlineInsertTemplate>

<AdvancedInsertTemplate>

<scheduler:AdvancedForm runat="server" ID="AdvancedInsertForm1" Mode="Insert" Subject='<%# Bind("Subject") %>' ... />

</AdvancedInsertTemplate>

<AdvancedForm EnableCustomAttributeEditing="True" />

<AdvancedEditTemplate>

<scheduler:AdvancedForm runat="server" ID="AdvancedEditForm1" Mode="Edit" Subject='<%# Bind("Subject") %>' ... />

</AdvancedEditTemplate>

</telerik:RadScheduler>

</asp:Content>

Since every action which triggers a postback (in this case, sorting, changing page and filtering) causes the loss of the state of the advanced form (every field becomes empty), I wrapped the RadGrid in a RadAjaxPanel. Now any of that action gives me the javascript error "Script control 'rfltMenu' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors()." and if I remove filtering support, it gives me the same error on another grid component and so on.

I read that the RegisterWithScriptManager attribute was introduced to handle these errors, I've set it to false and called the RegisterScriptControl() passing the RadGrid instance in the OnPreRender method of the AdvancedForm usercontrol, but to no avail.

Here is some excerpt from the usercontrol:

Excerpt from AdvancedForm.aspx:

<telerik:RadAjaxPanel ID="contactsRefreshPanel" runat="server">

<telerik:RadGrid AutoGenerateColumns="false" ID="ContactsGrid"

OnNeedDataSource="ContactsGrid_NeedDataSource"

AllowSorting="True" AllowFilteringByColumn="true"

AllowPaging="True" PageSize="2"

RegisterWithScriptManager="false"

runat="server">

<PagerStyle Mode="NextPrevAndNumeric" />

<MasterTableView AutoGenerateColumns="false" TableLayout="Auto">

<Columns>

<telerik:GridBoundColumn DataField="Name" HeaderText="Nome" SortExpression="Name"

UniqueName="Name" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Surname" HeaderText="Cognome" SortExpression="Surname"

UniqueName="Surname" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Company" HeaderText="Azienda" SortExpression="Company"

UniqueName="Company" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Email" HeaderText="Email" SortExpression="Email"

UniqueName="Email" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="CellularPhone" HeaderText="Cellulare" SortExpression="CellularPhone"

UniqueName="CellularPhone" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

</telerik:RadAjaxPanel>

Excerpt from AdvancedForm.cs:

public partial class AdvancedForm : System.Web.UI.UserControl

{

...

protected void Page_Load(object sender, EventArgs e)

{

UpdateButton.ValidationGroup = Owner.ValidationGroup;

UpdateButton.CommandName = Mode == AdvancedFormMode.Edit ? "Update" : "Insert";

InitializeStrings();

InitializeRecurrenceEditor();

// A series of client scripts registered

}

...

protected void ContactsGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

ContactsGrid.DataSource = Default.GetDataTable("SELECT * FROM Contacts");

}

...

protected override void OnPreRender(EventArgs e)

{

base.OnPreRender(e);

if (!FormInitialized)

{

FormInitialized = true;

}

if (!this.DesignMode)

{

// Test for ScriptManager and register if it exists

ScriptManager sm = ScriptManager.GetCurrent(Page);

if (sm == null)

throw new HttpException("A ScriptManager control must exist on the current page.");

sm.RegisterScriptControl(ContactsGrid);

}

...

}

Perhaps there something in the Ajax settings which isn't correct? I tried many things, including using RadAjaxManagerProxy to ajaxify the grid only but without results.
Any other suggestion is welcome. I'm stuck on this problem for 2 days.

By the way, I'm using RadControls Q1 2011 SP2.

Thanks in advance!

Hi Francesco,

I noticed that you have configured RadAjaxManagerProxy to ajaxify RadScheduler. In this case, all controls in the advanced form will also be ajaxified and there is no need to wrap RadGrid in an UpdatePanel.

I did a sample using your code, but everything worked as expected. Please, test the attached demo and let me know what is different at your side.
