CssFiles don't work when RadEditor inside RadWindow

I have the following RadEditor:

<telerik:RadEditor ID="RadEditor1" runat="server" EditModes="Design, Preview" Skin="Outlook" EnableResize="true">

<CssFiles>

<telerik:EditorCssFile Value="StyleSheet.css" />

</CssFiles>

<Content>

Editor content 1

</Content>

</telerik:RadEditor>

The css inside StyleSheet.css is applied to the content of the RadEditor as expected. However, when this RadEditor is placed inside a RadWindow the css doesn't work.

How can I get the css to work when the RadEditor is inside a RadWindow?

RadToolTipManager OnAjaxUpdate not firing after RadAjaxManager OnAjaxRequest

EDIT: I just realize The title is misleading. The OnAjaxUpdate DOES fire, but I get the error: 'Sys.ArgumentNullException: Sys.ArgumentNullException: Value cannot be null.Parameter name: panelsUpdated[0]'.

I have a RadGrid inside a panel and I Ajaxify the panel as an AjaxSetting using an RadAjaxManager. A popup window let's the user add items to the grid on closing via javascript, which then calls the RadAjaxManager's AjaxRequest. This all works great.

I have a couple RadToolTipManager's that are wired to elements in the RadGrid. On page load or reload, the tooltips work great. However, if the user adds an item via the popup window which calls the RadAjaxManager's AjaxRequest, the tootips don't work (unless the page is refreshed which defeats the purpose). All the user gets is the native tooltip text and nothing else.

So, after reading the forums, I realized I needed to add each RadTooltipManager as AjaxSettings in the RadAjaxManager. I did that and the tooltip begins to fire now, but after a few seconds it tosses an error: 'Sys.ArgumentNullException: Sys.ArgumentNullException: Value cannot be null.Parameter name: panelsUpdated[0]'.

Here's the HTML side of things...

<telerik:RadCodeBlock>

<script type="text/javascript">

function OnClientClose(oWnd, args) {

var arg = args.get_argument();

if (arg) {

var retValue = arg.ReturnValue;

if (arg.ReturnValue == "ONE" || arg.ReturnValue == "TWO") {

var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");

ajaxManager.set_enableAJAX(true);

///this calls RadAjaxManager1_AjaxRequest() server side

ajaxManager.ajaxRequest(arg.ReturnValue);

}

else {

__doPostBack('__Page', 'REFRESH|' + retValue)

}

</script>

</telerik:RadCodeBlock>

<des:PageManager ID="PageManager1" runat="server" AJAXFramework="TelerikRadAJAX"

AJAXControlID="ScriptManager1">

<ChangeMonitor Enabled="True" UseValidationGroups="True" />

</des:PageManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="pnlONE">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnlONE" LoadingPanelID="AjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="pnlTWO">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnlTWO" LoadingPanelID="AjaxLoadingPanel1" />

<telerik:AjaxUpdatedControl ControlID="RadToolTipManager1" />

<telerik:AjaxUpdatedControl ControlID="RadToolTipManager3" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="AjaxLoadingPanel1" runat="server" Transparency="55"

BackColor="#E0E0E0">

<div style="text-align: center">

<asp:Image ID="imgPanelImage" runat="server" AlternateText="Loading..." ImageUrl="~/Images/ajax-loader.gif" />

</div>

</telerik:RadAjaxLoadingPanel>

And the C# side....

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

RadToolTipManager1.TargetControls.Clear();

RadToolTipManager3.TargetControls.Clear();

//this is called from ajaxRequest() client side

if (e.Argument == "ONE")

grdONE.DataBind();

else if (e.Argument == "TWO")

grdTWO.DataBind();

}

protected void grdTWO_ItemDataBound(object sender, GridItemEventArgs e)

{

...

this.RadToolTipManager1.TargetControls.Add(...)

this.RadToolTipManager3.TargetControls.Add(...)

...

}

protected void OnAjaxUpdate(object sender, ToolTipUpdateEventArgs args)

{

this.UpdateToolTip(args.Value, args.UpdatePanel);

}

private void UpdateToolTip(string elementID, UpdatePanel panel)

{

...

}

Any ideas?

Thanks for any help,
Robert

ASPX page sequence is the default one but some time the sequence of the Column should be changed Programmatically after setting the DataSource

Thanks in advance ,

Radfilter DropDown Highlighted after selection

hey guys, i noticed that on the RadFilter (not Grid Radfilter) - that when there's a drop down list and something is selected - it stays highlighted - i assume this is by design until of course you click the "Apply" button. in my scenario - i'd like to attach an Enter Key event to the page - which i've done & it works fine. However, when using the DropDown List - this isn't the case. it holds the focus until you say "tab" or do another action.
is there some client code that will give the control back to the page when something is selected??
thanks again for any suggestions on this.
