Trial version issues for RadControls for ASPNET AJAX Q1 2009

To whom it may concern:

I have downloaded a trial version of RadControls for ASPNET AJAX Q1 2009 and come acoss of the following issues, just wantt o confirm whether it is related to the trial:

1. "Error: Sys.WebForms.PageRequestManagerParserErrorException: The

message received from the server could not be parsed. Common

causes for this error are when the response is modified by calls to

Response.Write(), response filters, HttpModules, or server trace is

enabled."

2. Cannot load a user control with embedded RadGrid in the content page:

"Control 'ctl00_ctl01_RadGridRolesPanel' of type 'OurUpdatePanel' must be placed inside a form tag with runat=server."

The code is as below:

UserControl ctrl = this.LoadControl("~/User Controls/Roles.ascx") as UserControl;

this.Page.Controls.Add(ctrl);

3. If I move the javascript from the master page to the .js file:

function InitiateAsyncRequestComboBox(sender, eventArgs) {

var ajaxPanel = $find("<%= RadAjaxPanel1.ClientID %>");

ajaxPanel.ajaxRequest("SelectedApplication:" + eventArgs.get_item().get_text());

}

function InitiateAsyncRequestPanelBar(sender, eventArgs) {

var ajaxPanel = $find("<%= RadAjaxPanel1.ClientID %>");

ajaxPanel.ajaxRequest("ClickedItem:" + eventArgs.get_item().get_text());

}

the above ajaxPanel returns null. However, leaving it into the site.master file is not debugable.

Cheers

William

I just noticed that when I place the RadGrid in Edit or Insert mode and the MasterEditTemplate shows the grid has paged down to the last page. Can this be prevented?

Call to RadEditor inside updatepanel

When I call via server side RadEditor which is inside a standard update I get an error in Firefox 3.0 as below. Does it need to be inside a RadUpdatePanel?

Reditor.Controls.Add(r);
[Exception... "Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsISupports.QueryInterface]" nsresult: "0x80004002 (NS_NOINTERFACE)" location: "JS frame :: chrome://snipit/content/snipitOverlay.js :: anonymous :: line 150" data: no]

this._upperAbbrMonths = this...s.dateTimeFormat.AbbreviatedMonthNames);

This the server side code:

            r.Width = 740;
            r.Height = 600;
            r.ID = "RadEditor1";

            Reditor.Controls.Add(r);
}

Self referentail grid - with setting of expandable flag.

Hi,
Currently I am working with self referential grid, I want to get first level of nodes once and when user clicks expand button, I want to get the second level of nodes from DB. To acheive this I want to set flag GridDataItem.CanExpand to true (since all the nodes may not be expandable).Unfortunately It says that the property "canexpand" is read only.

This is the blocker for my requirement.

Additionally I should be able to change the rows in detail tables and, in fact detail tables insertion and removal based on some external link clicks.

Please do let me know if following are possible.
Insert and Delete detail tables of self referential grid based on some external link clicks.
Instead of getting all levels of self-referential grid at time, if I can get only top most nodes and work on getting rest of nodes based on the expansion of grid rows(HierarchyLoadMode="serverOnDemand").

Any help would on this would really be a great favour.

Incorrect Toolbar Icons

In Rad Editor 2008.3.1314.35.

It appears that Icon Possitions in the Editor style sheet for the Save and Cancel Buttons are incorrect.

The Save button is rendering as a tiny arrow and the Cancel Button is rendering as a Envelope with a Lock over it.
..\RadControls for ASPNET AJAX Q3 2008\Skins\editor.css
Contains

.Cancel

{

background-position: -1687px center;

}

.FileSave,

.FileSaveAs,

.Save,

.SaveLocal

{

background-position: -1407px center;

}

These position appear to be the Icon locations in the previous version of the Style Sheet.

How should I edit the editor.css to reflect the correct locations?

hidden menu dropdown inside rotator

I've tried placing radMenu items inside a rotator (as described here: http://blogs.telerik.com/KevinBabcock/Posts/09-02-28/RadRotator_and_RadMenu_for_ASP_NET_AJAX_Building_an_Interactive_Menu_Together.aspx) and have found that if the menu has a dropdown - it gets cutoff at the edge of the rotator.

I've tried setting the z-index, changing the CSS overflow settings - but nothing seems to work. Any way around this?

RadTreeView not showing ability to expand structure

I am working with a load on demand version within a tabbed view and within a splitter. I create my first node with the idea that when you click on the plus sign you can expand to the next node, but my plus signs do not show up in this example. It seems that the ExpandMode="ServerSideCallBack" is not working at all. I am finding simple formats are working but even the imageurl I have passed is not showing either. Thoughts on what I might be doing wrong or am missing?
