Recurrence Rule ignoring "End After 'X' Occurrences" and using tomorrow as the "End By" date

I am using the 2010.3.1510.40 version. When I add an event with recurrence all works fine if I leave it with no end date.
However, if I try to use the "End After 'X' occurrences" option, the rule that is generated does not include anything for that limit and I get an event that recurs forever.
Also, if I try to use the date picker to end a recurrence by a certain date, the rule that is generated has tomorrow's date (no matter what I chose for the end date).

Here is the generated rule for an event that I set with Weekday occurrence, starting on 7/4/2011 and it was supposed to end on 7/9/2011:
DTSTART:20110704T180000Z
DTEND:20110704T200000Z
RRULE:FREQ=DAILY;UNTIL=20110624T050000Z;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR

The "UNTIL" is specified as 6/24/2011 so, needless to say, none of the occurrences ever showed up.

Is there a workaround for this issue?

Thanks.

Microsoft JScript runtime error: 'null' is null or not an object

We have successfully used several Rad Controls in our preexisting AJAX enabled project, but are unable to get spell check working on the RadEditor.

When I click on the spell icon I get the following error:

Microsoft JScript runtime error: 'null' is null or not an object

The debugger shows the error as occurring in the following function:

// Name: HTMLEditor.EditPanel.debug.js

// Assembly: AjaxControlToolkit

// Version: 3.5.50508.0

// FileVersion: 3.5.50508

_invokingRequest: function(sender, args) {

if (this._contentPrepared) {

return;

}

var webRequest = args.get_webRequest();

var body = webRequest.get_body();

// change body here...

var reg = new RegExp("([\\?&])(" + this.get_contentElement().name + "=)([^&$]*)([&$])", "g");

this._prepareContentForPostback(this.get_content());

>>> body = body.replace(reg, "$1$2" + escape(this.get_contentElement().value) + "$4"); <<<- body is null

this._contentPrepared = true;

webRequest.set_body(body);

},

I followed the directions for adding RadControls for ASP.NET AJAX to an existing application found here: http://www.telerik.com/help/aspnet-ajax/introduction-adding-radcontrols-prometheus-existing-application.html … and the recommendations for getting started with the editor here: http://www.telerik.com/help/aspnet-ajax/editor-getting-started.html
It should be noted the documentation specified configuration options in Step 9 which did not exist on the Smart Tag Menu (yes, we have the Telerik.Web.UI.dll in the project’s bin folder). Unable to add from the designer, I followed the directions found here: http://www.telerik.com/help/aspnet-ajax/editor-enable-spellcheck.html and manually added the spell check handler to my web.config, resulting in the editor displaying on the UI with a spell check icon on the toolbar.

I also tried substituting in a RadScriptManger in place of the ASP ScriptManger, but that only led to another problem:

Microsoft JScript runtime error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the AjaxScriptManager in System.Web.Ajax.dll, or use the ToolkitScriptManager in AjaxControlToolkit.dll.

We are developing in VS 2008. Any help is appreciated.

Best Practices to Create Online Help?

In years past, when I strictly built WinForms applications I'd use an old product called RoboHelp to build the Windows help files. It worked fine and was the right tool for the job.

Fast forward to 2011 and I'm in the midst of an ASP.Net 3.5 Intranet application. I'm now looking to provide some online help for it, which would include:

Context sensitive help from each page in the app.
A general search facility where the user could enter keywords and be shown the applicable help topics.

I could, of course, build this help engine from scratch but I'm thinking there must be a better, easier way. I'm thus curious whether the great minds at Telerik might have some suggestions, including the use of some of your controls in the ASP.Net AJAX toolkit.

A fairly open question, I know, but am hoping you can give me some good ideas,

Robert

Popup Edit User Control StartupScript

Hi,

I am using the popup form edit mode in the radgrid. In the edit form I have a user control. I want to run some javascript when the control is loaded. I tried using the Page.ClientScript in the Page_Load event of the control itself but that script never gets called.

Where is the appropriate event to hook into?

Add New Node Context Menu - Capture Text

I have a context menu where I add new nodes. I used this example to create the context menu:http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/contextmenu/defaultcs.aspx. My issue is that when a user add's a new node I need to capture what the user names the node, so that I can add it to the database. Currently the code uses javascript to set the node as editable on Page Load.

How do I go about capturing the text value the user inputs when adding a new node?

JAVASCRIPT

<script type="text/javascript">

//<!--

function onClientContextMenuShowing(sender, args) {

var treeNode = args.get_node();

treeNode.set_selected(true);

//enable/disable menu items

setMenuItemsState(args.get_menu().get_items(), treeNode);

}

function onClientContextMenuItemClicking(sender, args) {

var menuItem = args.get_menuItem();

var treeNode = args.get_node();

menuItem.get_menu().hide();

switch (menuItem.get_value()) {

case "Rename":

treeNode.startEdit();

break;

case "addLocation":

break;

}

//this method disables the appropriate context menu items

function setMenuItemsState(menuItems, treeNode) {

for (var i = 0; i < menuItems.get_count(); i++) {

var menuItem = menuItems.getItem(i);

switch (menuItem.get_value()) {

case "Rename":

formatMenuItem(menuItem, treeNode, 'Rename "{0}"');

break;

case "addLocation":

if (treeNode.get_parent() == treeNode.get_treeView()) {

menuItem.set_enabled(false);

}

else {

menuItem.set_enabled(true);

}

break;

}

//formats the Text of the menu item

function formatMenuItem(menuItem, treeNode, formatString) {

var nodeValue = treeNode.get_value();

if (nodeValue && nodeValue.indexOf("_Private_") == 0) {

menuItem.set_enabled(false);

}

else {

menuItem.set_enabled(true);

}

var newText = String.format(formatString, extractTitleWithoutMails(treeNode));

menuItem.set_text(newText);

}

//checks if the text contains (digit)

function hasNodeMails(treeNode) {

return treeNode.get_text().match(/$[\d]+$/ig);

}

//removes the brackets with the numbers,e.g. Inbox (30)

function extractTitleWithoutMails(treeNode) {

return treeNode.get_text().replace(/\s*$[\d]+$\s*/ig, "");

}

//-->

Columns loose their width

I have a radgrid and because I wanted the expand button to be shown on the right most column part of the grid, i set in mastertableview the attribute ExpandCollapseColumn-Visible="false" and added a new GridTemplateColumn with a button that performs the expand command.

<telerik:GridTemplateColumn ItemStyle-Width="27px" ItemStyle-Height="46px" Resizable="false"                 >
            <ItemTemplate>
                <asp:Button CommandName="ExpandCollapse" runat="server" ID="EC"   CssClass="expandbutton" />
            </ItemTemplate>
        </telerik:GridTemplateColumn>
Obviously in code behind, I intercept my command and the nestedviewtemplate in my case is shown correctly on expand. So far so good, expand and collpase work fine, the problem is that on expand, the columns of my grid (outer grid) loose their size(some become smaller, same become larger than in the all collapsed state). I tried setting Resizable=false on all GridTemplateColumn, but no result....
Any ideas? Can you please help?

Thank you,
Marina
