ascx onload

I have an ascx page that has a couple of RadComboBox controls. Those comboboxes have a RadTreeView template populated with some values. When the user clicks on the nodes the combobox's text changes. This all works pretty well. My problem however is that when the user submits the form, and he missed one or more fields, the checked nodes remain checked (which is a good thing) but the text in the combobox gets cleared again. I need to fire an onload event in which I can run through the treeviews and set the text of the comboboxes.

The code that I use to try to get this effect:

    
            function addEvent(evnt, elem, func)  
        
                { 
        
                    if (elem.addEventListener) // W3C DOM 
        
                        elem.addEventListener(evnt,func,false); 
        
                    else if (elem.attachEvent) // IE DOM 
        
                    {  
        
                        var r = elem.attachEvent("on"+evnt, func); 
        
                    } 
        
                    return r; 
        
                } 
        
                addEvent(window.onload,load()); 
        
            function load() 
        
                { 
        
                    var comboClass = $find("<%= rcClass.ClientID %>"); 
        
                    var comboCountry = $find("<%= rcCountry.ClientID %>"); 
        
                    var comboTm = $find("<%= rcTrademark.ClientID %>"); 
        
                    var comboYearFrom = $find("<%= rcYearFrom.ClientID %>"); 
        
                    var comboYearTo = $find("<%= rcYearTo.ClientID %>"); 
        
                    var comboType = $find("<%= rcType.ClientID %>"); 
        
                    var treeClass = comboClass.get_items().getItem(0).findControl("TreeClass"); 
        
                    var treeCountry = comboCountry.get_items().getItem(0).findControl("TreeCountry"); 
        
                    var treeYearTo = comboYearTo.get_items().getItem(0).findControl("TreeYearTo"); 
        
                    var treeYearFrom = comboYearFrom.get_items().getItem(0).findControl("TreeYearFrom"); 
        
                    var treeTrademark = comboTm.get_items().getItem(0).findControl("TreeTrademark"); 
        
                    setText(comboClass,treeClass,0); 
        
                    setText(comboCountry,treeCountry,2); 
        
                    setText(comboTm,treeTrademark,1); 
        
                    setYear(comboYearFrom); 
        
                    setYear(comboYearTo);      
        
                }

However, I get the error in the load() function that all the comboboxes return 'null'.

Show from server-side

How can I show and hide a tooltip from the server? I don't want the tooltip to be displayed when the user puts the mouse over the control. I want to be able to control when it is displayed or hidden from the server-side.

confirm if radwindow must be close. (Showing a radconfirm on close of a window )

Hi, me again, I need to do the same like its exposed on the forum:
some similar
but I have different mistakes, this is the scenario:

    
            function onBeforeClose(sender, arg)  
        
            {  
        
                function callbackFunction(arg)  
        
                {  
        
                    if (arg)  
        
                    {  
        
                        sender.remove_beforeClose(onBeforeClose);  
        
                        sender.close();  
        
                    }  
        
                }  
        
            arg.set_cancel(true);  
        
            radconfirm("Are you sure", callbackFunction, 300, 100, null, "Close RadWindow");  
        
            }  
        
            //this function call a window when I click a menu item 
        
            function menuClick(sender,arg)  
        
            {    
        
            //show window .... 
        
            //.... 
        
            //this comment lines not work, I try both 
        
            //wnd.add_beforeClose(onBeforeClose);  
        
            //sender.add_beforeClose(onBeforeClose);  
        
            //but this work. its a closing event not before close 
        
            wnd.add_close(onBeforeClose); 
        
            }

and when i close this its the message error: arg.set_cancel is not a function,
I read on the forum something like if its no the right method this error shows but, 'add_beforeClose' dont work to me yet.
there another way to call this event?
I'm a litle confused.

    Thanks in advance.

Help with manipulating elements inside the editor with javascript

I have a small app that uses the radeditor. In it I insert pictures into the editor’s document by pasting some HTML using the pasteHTML method.

Wht I paste is normaly this image tag or similar one:

"<img alt="" id="Tempdivphoto0" src="PhotoFeeders/GetNewTempForumPostPhotoThumbNail.aspx?ForumPostTempPhotoIndex=0&Time=1238702704906" />"

When the user submits the document, my application then has to change all the <img> tags that were pasted into <div> tags. I dothis in javascript with this small function:

The id of the <img> tag is in this: $find(element).get_TempID()

Posteditor is the clientID of the editor

if

($get($find(element).get_TempID(), $find(Posteditor).get_document()) != null) {

var temImg = $get($find(element).get_TempID(), $find(Posteditor).get_document());

var div = $find(Posteditor).get_document().createElement("div");

var uniqueIDv = this._UniqueID;

div.id = uniqueIDv + index.toString();

div.className =

'ForumPostPhotoDivCss';

$find(Posteditor).get_document().body.insertBefore(div, temImg);

$find(Posteditor).get_document().body.removeChild(temImg);

The problem I am having is this:

If the user only types some text and pastes images then the HTML of the editor looks something like this and all works fine:

this is a test

However, if the user selects the entire content of the editor and decides to align it ‘centre’ then the HTML in the editor looks like this and it does not work because of the tag surounding it.

this is a test

The same problem occurs when the user selects the content of the editor and puts it in bold, then it wraps it up in these tags an it also does not work.

this is a test

The error is this line:

$find(Posteditor).get_document().body.insertBefore(div, temImg);

Where it says:

Error: [Exception... "Node was not found" code: "8" nsresult: "0x80530008 (NS_ERROR_DOM_NOT_FOUND_ERR)" location: "http://localhost:1761/BCW_Web/Scripts/ForumsAJAX.js Line: 369"]

Source File: http://localhost:1761/BCW_Web/Scripts/ForumsAJAX.js

Line: 369

How can I reference the div and/or the image correctly when they are wraped inside or <div> tags?

Why did you change the Default skin!?!?!?!?

I've spent months working with the default skin. I purchase the product to get it into production and you change the Default skin!!! Now I have to spend more of my free time hacking this crap to get it to look like the 2008 default skin. AND I have a damn demo tomorrow.

Can you feel my rage here!?

Removing last character in a paragraph... bug?

Hi,

I'm using RadEditor 5.3.2 in MOSS and I configured to use it in a list. So far, so good.

Then I select a paragraph, or some text, and apply a custom css using the "Apply Css" button. Good! Then, if I remove the last character in the selected text/paragraph above, the styles is applied to the entire html after the initial tag.

Is that a bug or I'm doing something wrong?

Thanks in advance,

Guilherme

How to customize slider and buttons

Is there a way to customize the Decrease, Increase button so I can position them differently and change the size of those buttons?
I want a horizontal slider but I want the Decrease (Previous) and Increase (Next) buttons to be about 50px above the slider.

Is there a way to make the horizontal slider thicker? Or make it look like this?
