Client binding - Webservice method called twice

Hi all,

with the latest release, I am using Web services databinding for my data-grid.

What I can figure out using a basic net profiler (Firebug extension in Firefox), is that the webservice method to retrieve the data is called twice (with a consequent doubled load on the Web, Business logic and Database tiers).

I am using the basic code in the samples. Any work-around on that?

Thanks,
Enrico Foschi

RadTreeNodeData - Client side dataBind()???

Hi,

I am trying to load a RadTreeView using client side databinding using Hierarchal data from database.
Could you please let me know whether the following is possible using RadTreeNode
1. How can i convert the Hierarchal data (I have got more that 3 child node levels) from the database, dynamically to build the RadTreeNodeData[ ] object, so that i can pass it to the RadTreeView using Webservice call or AJAX request?
2. Is there a dataBind() client side property in the RadTreeView alike RadGrid object, so that i can retreive the RadTreeNodeData[] object and bind it to the RadTreeView object? Or <WebServiceSettings Path=".." Method=".."> settings is the only way to bind the RadTreeView using Webservice call?

Actually my requirement is to load the RadTreeView control which is available inside the ItemTemplate of RadComboBox control. I want to populate the RadTreeView control on dropdown opening event.

Thanks for your support.

Thanks and regards
Sundar

[Solved] RadControls in TableCells within Master Pages

I have a RadDatePicker in a TableRow1
I have another RadDatePicker in a TableRow2
This table is on a ascx page posting to a master page.
In the design it looks fine but when I debug instead of them being right on top of each other there is a huge space between the rows.
I checked styles and they are not set to anything extraordinary.
It also does this same thing for a RadComboBox set in a TableCell.

Is there something I need to format or a special property? Do I have to make a change to the master page to allot for the radcontrols?

It seems as though the cell is allotting space for the when the javascript works.

Thanks.

RADFileExplorer Item selection

I'm evaluating RadFileExplorer as an alone component. There is a way to select an Item server side? Or js?
I've found only the possibility to set:
Configuration.ViewPaths and InitialPath.

Rotator does not re-position when resizing a page with centered body

Hi, I have my page center on the browser, as follows:

<body style="width: 960px; margin: 5px auto 0;">

On the left hand side, I have a navigator menu. Below it, I put a rotator to show some news.

Problem: when I resize the browser window (IE), the rotator does not relocate. However, it works on FF3 and Opera.

Any idea?

Thanks

ImageManager script and server side action

Hi,

I have many problems to build my ImageManager and make one Button_Click server side in the same action. To lauch the Image Manager I use one classical javascript like :

    
            <script type="text/javascript">  
        
                var currentTextBoxID;    
        
                function ImageManagerFunction(sender, args)    
        
                {    
        
                    var selectedItem = args.SelectedItem;    
        
                    var resultImageObject = args.Result;    
        
                    var txt = $get(currentTextBoxID);    
        
                    txt.value = selectedItem.getPath();    
        
                }            
        
                </script> 
        
                <asp:TextBox ID="Linkthumb4" runat="server"></asp:TextBox> 
        
                <telerik:dialogopener runat="server" id="DialogOpener1" >    
        
                </telerik:dialogopener> 
        
                <button onclick="currentTextBoxID='<%= Linkthumb4.ClientID %>';$find('<%= DialogOpener1.ClientID %>').open('ImageManager');return false;">Select</button>

And the constructor server side. My problem is that I need to lauch another action server side with the button_Click event. I have tried changing the single button to one asp:button runat server and add the javascript with one attributes.add, but in this case the "<%= %>" are not well interpreted.

<

asp:Button ID="Action" runat="server" Text="Select" Width="60px"/>

script.
in addition..
function

lauch()

{

currentTextBoxID=$get(

'Linkthumb4'); NO working well to search the Linkthumb4.Client ID

$find($get(

'DialogOpener1')).open('ImageManager'); NO working well get DialogOpener1.ClientID

}

codebehind

Action.Attributes.Add(

"onClick", "lauch();return false;"); added server side to add after my code
...mycode

Someone have one solution to build completly this ImageManager server side or to attach one complementary action server side to asp:button without postback event.

Thanks.

[Solved] eventhandler for Html area

Hello,

I intend to fire an event if the user changes some content in the design and html mode, too by using code like this:

OnKeyDownTextEditorHandler = function (e)
{
//do some stuff
};

myEditor.attachEventHandler("onkeydown", OnKeyDownTextEditorHandler);

This is working fine for the design mode but in the Html mode there is no event fireing anymore. I found some old posts, telling u have to find the editor in the dom and append the event manually.This solution can not be the only one. There has to be a buildin editor feature which solves that issue because it is usual and often needed I guess. Maybe someone can give me a hint.

thank u

[Solved] Paste problems with MS Word 2003 and Firefox 3.0.3

Hi,

I've read some threads concering paste issues with RadEditor control.

Unfortunately i haven't found solution to my issue.

The problem arises when pasting the text from MS Word to RadEditor (in Mozilla Firefox 3.0.).

RadEditor is wrapped in the DetailsView and when i click the upload link the content is saved in the

database. When previewing the content in the Literal control (in IE 7) strange syntax is displayed:

The problem is that IE doesnt recognize this as a comment (because of <!--[ instead of <!--) and

displays is as the text in the website. To make things clearer: The problem is that FF puts some

additional html comments when pasting content from MS WORD. IE does not recognize that as

a comment and displays it.

Things work just fine If i try the other way around (paste text from MS WORD in IE and preview it in FF).

Could someone help me with this issuse as it is annoying.

thx
