I am using RADEditor for MOSS. I created function to set focus in textbox and assigned
RadEditor.OnClientLoad = "JavaScript function name";
my code to set focus is in JavaScript function.
My problem is that javascript function executes fine in IE6, but it doesn't set focus in textbox. Same code works fine in Firefox.
Can anybody please help me?

I've run into a problem when I use an RadAjaxManager on a control that contains controls from the AjaxControlToolkit. It seems the minimal amount of code to cause the problem is to take a control deriving from INamingContainer such as a wizard and either place it in a RadAjaxPanel or reference it in a RadAjaxManager. Then place an AjaxControlToolkit control such as the MaskedEditControl on the page.
When an async postback occurs an "Object reference not set to an instance of an object." error is thrown.
A little debugging showed the error was coming from the ExtenderControlBase.GetScriptDescriptors method in the AjaxControlToolkit and the targetControl parameter provided was null.
I've found a temporary solution where I handle the OnPreRender event of each AjaxControlToolkit control and set it's TargetControlID to the UniqueID of the target control. Is this a bug in the RadAjaxManager or is this temporary solution the correct solution?
Thanks,
Chris

I have been through the different examples of using MasterPages and UserControls with RadAjax for a couple of days. I have gotten pretty far. Here is my masterpage (relevant sections only):
Here is my Default.aspx:
Default.aspx.cs:
And the user control MyGrid.ascx:
| <asp:ScriptManager ID="ScriptManager1" runat="server" /> |
| <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" EnableHistory="True" /> |

Here is my Default.aspx:

And the user control MyGrid.ascx:

// --> It seems you wire up the OnAsyncPostBackError event of the Script Manager and run any Logging that needs to be done there and you can change the output <-- //
I am now getting the following Stack Trace for my error that is occuring when I have a usercontrol inside a wizard. When I wire up a button to ajaxify the whole wizard and then click on a button that fires an event i get this error.
With the old RadAjaxManager there was a method called OnAjaxRequestError that could be called to catch erros and display them on screen. Now it appears that method is not there in Prometheus or I have totally missed it.
I am getting a rather ubiquitous error or Object reference is not set to an instance of an object. Just wonderign what I can use to catch the error and get a little bit more out of it.

I am hoping to overcome the infamous "Browser Back" issue. When the user clicks on an item in a Radgrid and travels to a different page, I need to have that same grid and data available if the user navigates "Browser Back" to the page. To do this, I am trying to use "Prometheus" Ajax. I added the following to my page:
<asp:ScriptManager runat="server" id="ScriptManager1">
</asp:ScriptManager>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="loadingPanel" EnableHistory="True">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="rgSearchResults">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="rgSearchResults" LoadingPanelID="loadingPanel" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel ID="loadingPanel" runat="server" Width="75px" Height="75px" Transparency="20">
<asp:Image ID="Image2" runat="server" AlternateText="Loading..." ImageUrl="RadControls/Ajax/Skins/Default/Loading.gif" />
</telerik:RadAjaxLoadingPanel>
where rgSearchResults is the radgrid that I am very interesting in preserving in the Browser Back situation. I also turned off the ajax on rgSearchResults. I don't experience any compilation errors, but I get a postback when I click within the grid on a linkbutton. I then tried it on a simple linkbutton outside of the grid, but experienced the same result.
I am not sure if it is related, but in my Source view, the editor underlines "ScriptManager" as an error (unrecognized), but does not produce an error. It compiles. If I look in my toolbox, there is in fact a ScriptManager, so I am not sure why it is underlining as an error.
I am not sure if this is related or not, but once I added the ScriptManager and AjaxManager, I received a js error on the page that reads: 'Sys' is undefined. If I remove the ScriptManager and AjaxManager, the js error goes away.
<asp:ScriptManager runat="server" id="ScriptManager1">
</asp:ScriptManager>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="loadingPanel" EnableHistory="True">

I need to have the user select images from the database using dbcontentprovider (which is working BTW, thank you), and also be able to include files from the filesystem. That is, I want to be able to create html that looks like this:
start:
<img src="http://localhost:51833/KnovoloWeb/ItemHandler.aspx?path=Root/Content113/turtle.jpg" /><br />
<img alt="" src="/photo/img/01B.jpg" />
end:
Can I do this with different folders in the image manager button? Or, can I add a second Image Manager button to the editor, one for images from the file system and one for images from the database?
Thanks
