Add New Record and + sign function differently in Radgrid

Hi,

We have two Radgrids on a web content page. For one grid, the edit form is an aspx page. When you click edit in the grid, an aspx page is loaded into the edit section of the grid. We created an eventhandler for onbeforeunload event for the aspx page, so when user leaves the aspx page(have the edit section open) and click on a button, linkbutton, leave the content page...etc, a popup will display. This works great except clicking the Add New Record in the other grid displays our pop up and clicking the +sign(left to Add New Record) doesn't, which confuses our users. Refresh button and its sign have the same issue.

Could any body help me?
Thanks & Regards,
Zwu

OnAjaxUpdate Error in Tooltip RadGrid

I basically want to use the Tool / ToolTipified Grid from the Telerik, I followed pretty much the same instructions with a bit of differences in ascx. But it gave me the error:

RadToolTipManager response error:
Exception=Sys.WebForms.PageRequetManagerServerErrorException: Object reference not set to an instance of an object.

And the tooltip fires but content is not populated.

Below are my codes:

With DisableFilter(RemoveScripts) still have some <script removed when multiple <script tags exist in content

Using version: Version 2009.3.1208 (Dec 8, 2009)

I have disabled the RemoveJavascript filter using the following code:
RichTextEditor.DisableFilter(EditorFilters.RemoveScripts);
RichTextEditor.DisableFilter(EditorFilters.EncodeScripts);

Now, in the UI in HTML mode I paste in the following code:
<script type="text/javascript" src="http://cdn.widgetserver.com/syndication/subscriber/InsertWidget.js"></script><script>if (WIDGETBOX) WIDGETBOX.renderWidget('ea4c7da5-c69b-4b5d-be46-c584cc005caf');</script><noscript>Get the <a href="http://www.widgetbox.com/widget/magic8ball">Magic 8 Ball</a> widget and many other <a href="http://www.widgetbox.com/">great free widgets</a> at <a href="http://www.widgetbox.com">Widgetbox</a>! Not seeing a widget? (<a href="http://docs.widgetbox.com/using-widgets/installing-widgets/why-cant-i-see-my-widget/">More info</a>)</noscript>

Click Save and the radEditor's contents at the server are:
<script type="text/javascript" src="http://cdn.widgetserver.com/syndication/subscriber/InsertWidget.js"></script>

Can someone explain to me why the other script content has been removed?

Thank you,

Image manager / Image editor arrow keys don't work

When I use the Telerik Editor, and clik on the Image Manager, a window with folders and files on the server appear.
When I try to move between folders or files with the up/down arrow keys, the whole explorer moves instead of changing the image preview between folder or files, as windows explorer does.
Is there any way to make that the up/down arrow keys change between files, to see different image previews without having to use the mouse?
Thank you!

Authentication Failed. Pop Ups. ImageMap and Tooltip

Hello, please see the following link, it is my source code:
http://www.fronseetechnology.com/ShortSalesWeb/Default.aspx

You will notice the US map, try hovering over some states, I know it does the issue for sure on CA. You will notice all of the pop-ups I am getting and it is just not working. I used the sample application here:
http://www.telerik.com/community/forums/aspnet-ajax/tooltip/imagemap-with-tooltip-and-database-data.aspx

and here: http://demos.telerik.com/aspnet-ajax/tooltip/examples/imagemaptooltipmanager/defaultcs.aspx

- Im not sure what I have wrong, it looks like it is trying to work, but there are authentication issues (i imagine with the web service?). Does anyone have any suggestions? OH, a big thing I was thinking about, instead of using a web service (.asmx), cant I just call a [webmethod] directly in the code behind? I have tried this with other code, but not this ImageMap and tooltipmanager. I gave Everyone permission to the directory on the server, and still these issues. Someone please help!!! Thank you

How to trigger Ajax load of a RadComboBox and select the first item loaded.

Hi,

After looking at the doc, I can't find all the hooks I need for a seemingly logical scenario: I have many RadComboBoxes on a page, and I need to load one or the other of them via client "onclick" events. For example, when a user clicks a checkbox, I need to load a related RadComboBox and also set the selected index to the first item loaded. I cant expect the user to check the checkbox and then also click on the RadComboBox to trigger it. Does anybody have an example or a tip how to do this? The easy part is the Ajax loading, the difficult part seems to be: fire and event to get the RadComboBox to start its ajax loading and also set the first item as selected in the ComboBox.

I have seen this post:
http://www.telerik.com/community/forums/aspnet-ajax/combobox/ajax-refresh-of-radcombobox.aspx

but aside from being very complex for a simple scenario (which I could live with), it doesn't work :-) No matter where I put the AjaxManager etc on my (non trivial) page, I get:
Please, see whether wrapping the code block, generating the exception, within RadCodeBlock resolves the error. ---> System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
eb.UI.ControlCollection.AddAt(Int32 index, Control child)....
Web.UI.RadAjaxControl.MoveUpdatePanel(Control initiator, Control updated)
inner exception stack trace ---
Web.UI.RadAjaxControl.MoveUpdatePanel(Control initiator, Control updated)...

It is wrapped, of course, just as in the example presented...

THANKS!
