Dynamically created tooltip inside a radgrid

Hello

I'm using rad q3 2008

I would like to implement what i think must be a fairly common scenario but i can't find anything on how to do it in the documentation.

I have a datagrid and one of the columns contains a hyperlink. When the user hovers over the hyperlink I would like a tooltip to be displayed.

The tooltip inside the radgrid row is created dynamically so I don't know how to add it to the target controls collection of the tool tip manager

I tried this but to no avail in the item data bound event of the grid

Dim tip As RadToolTip = e.Item.FindControl("tipStartAddress")

RadToolTipManager1.TargetControls.Add(tip.ClientID,

True)

Furthermore once i have got this bit to work I would like to have the tooltip load its content on demand. I really don't know how i would trigger an OnAjaxUpdate event for a tooltip and add controls to it on the server.

Also, the documenation only talks about the radtooltip with an updatepanel. I use radajax now. I presume you can use a tooltip with rad ajax

many thanks in advance

AutoResizeHeight in Firefox

I've noticed a bug in Firefox when setting the AutoResizeHeight property of the RadEditor to "true". After the editor is re-sizes, the cursor repositions to the top of the editor - so, if you were to continue typing, your text would begin appear at the beginning of the editor. This is reproducible on the AutoResizeHeight demo here: http://demos.telerik.com/aspnet-ajax/editor/examples/autoresizeheight/defaultcs.aspx

Place your cursor after the last "9.0+" (in the Linux column of the Netscape row) and hit enter. Begin typing and your text will appear at the top of the editor.

I've been able to reproduce this in Firefox 3.0.9 & 3.0.11.

[Solved] Error when loading frmo XML file

Hi all,

I have the following XML file as a data-source for the RadTreeView:

    
            <?xml version="1.0" encoding="UTF-8"?> 
        
            <codeBook xmlns:xsp="http://apache.org/xsp" xmlns:util="http://apache.org/xsp/util/2.0" xmlns:xsp-session="http://apache.org/xsp/session/2.0" xmlns:xsp-request="http://apache.org/xsp/request/2.0" xmlns:i18n="http://apache.org/cocoon/i18n/2.0" version="1.2.2" ID="ZA4350"> 
        
            <docDscr> 
        
            <citation> 
        
            <titlStmt> 
        
            <titl> 
        
            Title text goes here

            </titl> 
        
            </titlStmt> 
        
            </citation> 
        
            </docDscr> 
        
            </codeBook>

I load it using the following statement:

    
            RadTreeView rt = new RadTreeView(); 
        
            rt.LoadContentFile("file.xml");

I am getting the following error:

<codeBook xmlns=''> was not expected.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: <codeBook xmlns=''> was not expected.

I have read similar posts in these forums but don't see an answer to my problem. I can't alter the data to add an xmlns attribute to each element.

Any ideas?

Grid Columns Alignment/Performance Issue

Hi Telerik Team,

We are having issues in Grid Columns and Items alignment. Actually, we are doing alignment of columns and items on Grid's PreRender Event but that is not getting aligned. If we do the above process in Grid's ItemDataBound Event then this event is getting fired for every record(Item) in the DataSource which is degrading the System's Performance.

Please suggest how to do the above process while keeping System's Performance up-to-date.

Thanks,
Rajesh

[Solved] Could not load file or assembly 'Telerik.Web.UI...

Greetings, sorry to bring this issue up again. I have been researcing it for much too long now and need to ask for help.

I am demo'ing the RadControls for ASP.NET AJAX and have run into this error on my server. I am developing on a Vista Laptop with MS Visual Web Developer 2008 Express (demo'ing that too) and the trial version of RadControls. I have written a very excellent program that runs fine on my computer. The problem is when I build the site and upload the files to my server. It's like IIS cannot locate the telerik dlls in the /Bin folders.

Other Info:
I have a website set up under IIS with the /Bin folder in the root directory. My files I am playing with are also located in this directory. I have ASP.NET v3.5 installed. I found a forum about adding the dlls into the GAC but when I try to do that, it tells me the names aren't "strong."

Does anyone have a clue what I am doing wrong? I'm a programmer really so I am sure I've forgotten something or bumbled something up on the server. Any help and direction would be greatly appreciated.
